You are a Content Condenser for a memory-augmented retrieval system.
|
||||
|
||||
Your task is to compress the retrieved content while preserving all information that is highly relevant to the user’s query.
|
||||
|
||||
Guidelines:
|
||||
|
||||
Focus only on content related to the query; ignore irrelevant parts.
|
||||
Remove redundancy, filler, or repeated information only for non-XML content.
|
||||
Preserve all factual details: names, dates, decisions, code snippets, technical details.
|
||||
If relevant information is inside XML tags, do not remove, merge, or compress the XML tags or their internal text; keep them fully intact.
|
||||
Structure multiple relevant points as a compact bullet list or paragraph, depending on density.
|
||||
If no content is relevant, return exactly: "No relevant information found."
|
||||
Do not add any knowledge or facts not in the retrieved content.

## 这本书在讲什么
|
||||
|
||||
MemoryBear 把"非结构化资料 → 可被对话/Agent 检索消费的知识"这条 RAG 链路完整跑通了:从 Web/飞书/语雀/本地 11 类格式的解析、Chunking、Embedding、Elasticsearch 8.x 上的 Hybrid 向量+全文混合索引、Microsoft GraphRAG(general)与 LightRAG(light)双轨知识图谱、Reranker 三路实现、流式 LLM 调用、引用回填,到对话内存与 RAG 协同的产品差异化设计。
|
||||
|
||||
本文档全集是上述链路的**「源码级实现说明 + 架构改造路线 + 后续迭代蓝图」**。所有结论都锚定到具体的源码位置(`path:line`),不允许凭空虚构。
|
||||
|
||||
> **当前状态**:**Release Candidate 1(候选发布)**。S3-T1(架构改造建议)与 S3-T2(迭代功能路线图)已通过知识运营终审;Sprint-2 部分文档(S2-T4 GraphRAG、S2-T6 E2E、S2-T7 收口评审)尚未交付,对应章节为占位说明。完整 v1.0 在 S2 收口评审通过后发布。详见 [`_release/release-manifest-v1.0-RC1.md`](_release/release-manifest-v1.0-RC1.md)。

## 文档治理与如何贡献
|
||||
|
||||
- **质量标准**:所有文档遵循 [`_meta/document-template.md`](_meta/document-template.md) 模板与 [`_meta/scoring-rubric.md`](_meta/scoring-rubric.md) 5 维评分(≥80 通过)。
|
||||
- **审校流程**:作者自检(30min)→ 同行评审(48h)→ 知识运营终审(24h),见 [`_meta/review-sop.md`](_meta/review-sop.md)。
|
||||
- **保鲜节奏**:每个 MemoryBear release 同步评审;超过 2 个 release 未更新触发自动归档复审,见 [`_release/ops-and-freshness-plan.md`](_release/ops-and-freshness-plan.md)。
|
||||
- **版本号**:遵循语义化版本(v1.0 / v1.1 / v2.0),并在 frontmatter 锁定 `source-commit` SHA。详见 [`_release/versioning-convention.md`](_release/versioning-convention.md)。
|
||||

- 发现源码引用与代码不符:在对应子任务([WS-12 ~ WS-25](mention://issue/6c0b5472-a0fa-4997-925c-a67f235f82da))评论中标注,由责任专家修订。
|
||||
- 内容缺漏 / 阅读路径建议:在 [WS-24](mention://issue/a07f108d-06ee-41b8-8b57-22455f60ddeb) 评论中提交,由知识运营专家整理进下次保鲜窗口。
|
||||
- 安全 / 隐私 / 合规问题:请直接联系工作空间负责人,不要在公开 issue 中详细描述。

|---|---|---|---|---|---|
|
||||
| 1 | 全链路架构图 | Mermaid Flowchart | S1-T2 | `overview/01-architecture.mmd` | 11 个 RAG 环节 + 模块映射的全景图 |
|
||||
| 2 | 文档入库时序图 | Mermaid Sequence | S1-T2 | `overview/02-indexing-pipeline.mmd` | 上传 → Celery → naive.chunk() → Embedding → ES 写入完整时序 |

||||
|
||||
## 2. 速查:场景 → 应该看哪张图
|
||||
|
||||
| 场景 | 推荐图表 | 备注 |
|
||||
|---|---|---|
|
||||
| 给业务方 / 新人介绍 RAG 链路 | #1 全链路架构图 + #8 能力地图 | 两图配合即可"5 分钟讲清是什么" |
|
||||
| 排查"文档为什么没入库" | #2 文档入库时序图 | 找到失败的具体阶段 |
|
||||
| 排查"为什么搜不到这个 chunk" | #3 在线检索时序图 + #5 模块依赖图 | 时序图定位调用步骤;依赖图找上下游 |
|
||||
| GraphRAG 调试 | #4 GraphRAG 索引时序图 | light/general 差异点 |
|
||||
| 评估改造影响面 | #5 模块依赖图 + 本目录 `_indexes/file-index.md` | 看代码 → 文档涟漪 |
|
||||
| 给架构会做演进汇报 | #8 能力地图 + #9 后续迭代甘特图 | 现状 + 路线 |
|
||||
|
||||
## 3. 图表渲染说明
|
||||
|
||||
- **Mermaid 文件 (`.mmd`)**:可直接在 GitHub / Mermaid Live Editor / VS Code Mermaid 插件中渲染。
|
||||
- **代码块嵌入图**:直接在 Markdown 渲染器(如 MkDocs Material)打开对应文档即可看到。
|
||||
- **未来扩展(建议)**:在 v1.1 时为 `.mmd` 文件配套生成 SVG,挂在 Wiki 上避免 GitHub 渲染限制(当前 GitHub Mermaid 节点上限 1500,建议后续按需拆图)。
|
||||
|
||||
## 4. 待补图表(v1.0 → v1.1 计划)

|
||||
| TBD-2 | GraphRAG light vs general 的内部数据流图 | S2-T4(待重启) | S2-T4 启动 |
|
||||
| TBD-3 | "GraphRAG with evidence_path" 时序示意 | S3-T2 D3 落地 | D3 增量图演化第一阶段 |
|
||||
| TBD-4 | Memory ↔ RAG 协同时序图 | S3-T2 D4 落地 | D4 PoC-B 实施后回填 |
|
||||
| TBD-5 | 散点图:建议 # × 优先级 × 工作量 | S3-T1 + 评审反馈 | S3-T1 终审已完成;散点图作为可选优化 |

# _meta/ — 治理资产(待回填)
|
||||
|
||||
本目录用于存放 RAG 文档项目的治理资产(统一模板、评分卡、SOP、命名规范等),由 [WS-12 / S1-T1] 任务交付。
|
||||
|
||||
## 状态
|
||||
|
||||
[S1-T1] 任务的交付物在 [WS-12 评论 `93ea1f50`](mention://issue/b1ead19b-920b-494b-95b5-ab2057d4dd14) 中已声明完成(写入 agent 工作分支),但相关文件未持久化到 main 分支与本仓库 `docs/rag/` 目录树。本次 v1.0 文档全集提交时,按 [WS-26](mention://issue/5c12d0a3-89ea-4e92-adb4-d98eddfa3eab) 用户指示将仓库迁移到 `git.poflow.cn:30010/adai/MemoryBear.git`,本目录暂作占位,后续回填。
|
||||

## 回填路径建议
|
||||
|
||||
1. **首选**:从 [@知识运营与治理专家](mention://agent/7e9211a6-41eb-429e-9dd1-4c7afcffd412) 的本地工作目录恢复并提交。
|
||||
2. **次选**:基于 [WS-12 评论 `93ea1f50`](mention://issue/b1ead19b-920b-494b-95b5-ab2057d4dd14) 中描述的设计决策与各文件大纲,由知识运营重新生成(约 0.5–1 个工作日)。
|
||||
3. **快速兜底**:参考 [`../_indexes/glossary.md`](../_indexes/glossary.md) 与 [`../_release/versioning-convention.md`](../_release/versioning-convention.md) 中已沉淀的部分约束(如版本号约定、frontmatter 字段),先建立最小可用版本。

# MemoryBear RAG Docs · 运营与保鲜计划
|
||||
|
||||
> **目标**:让 `docs/rag/` 不沦为"上线那天的快照",而是与 MemoryBear 一同进化的活水。
|
||||
> **责任主线**:知识运营与治理专家牵头,与 PM / AI 知识库专家 / Python 工程师协同。
|
||||
|
||||
## 1. 保鲜原则(Why)
|
||||
|
||||
> 一句话:**代码会跑,文档会过期;过期速度比新代码合并的速度还快。**
|
||||
|
||||
- **失效快**:MemoryBear 在 Sprint-3 内合并的关键改造(如 Reranker 缓存、Embedder Protocol、`node.py:327 print` 删除)会在 1-2 周内让相关文档章节失同步。
|
||||
- **影响大**:本套文档是 toB 客户、二次开发者、内部 oncall 的"事实来源";与代码不一致会直接误导决策。
|
||||
- **维护成本可控**:用统一的"评审 + 增量更新 + 自动归档"三段式机制,把维护成本摊到每次 release,而不是堆在年度大修。
|
||||
|
||||
## 2. 保鲜节奏(When)
|
||||
|
||||
### 2.1 与 release 同步评审(强制)
|
||||
|
||||
每次 MemoryBear 主仓发 release(语义化版本 `v0.x.y`)时:
|
||||
|
||||
| 时点 | 动作 | 责任人 |
|
||||
|---|---|---|
|
||||
| **release 准备期 -7d** | 自动扫描:`git diff <last-release-tag>..HEAD -- 'api/app/core/rag/**'` 列出受影响文件 | PM 或脚本 |
|
||||
| **release 准备期 -5d** | 知识运营对受影响文件清单进行"文档涟漪映射"(用 `_indexes/file-index.md`) | 知识运营 |
|
||||
| **release 准备期 -3d** | 责任专家修订对应文档章节(最低粒度:源码引用行号、配置项默认值、流程描述) | AI 知识库 / Python 工程 |
|
||||
| **release day** | 知识运营终审;通过后将 `source-commit` 刷到新 commit | 知识运营 |
|
||||
| **release day +1d** | 在 `evolution/CHANGELOG.md`(v1.1 起新增)写入"对应 MemoryBear `v0.x.y` 的文档增量" | 知识运营 |
|
||||
|
||||
### 2.2 季度全量复审(强制)
|
||||
|
||||
每季度(3 / 6 / 9 / 12 月末)做一次"对所有文档的轻量复审":
|
||||
|
||||
| 步骤 | 内容 |
|
||||
|---|---|
|
||||
| 1 | 抽样 30%(每类文档至少 1 篇)做"源码引用一致性"抽查(用 `_indexes/file-index.md` 对应行号 grep ±3 行) |
|
||||
| 2 | 检查每个文档的 `last-reviewed-at`,超过 3 个月的标记为"待复审" |
|
||||
| 3 | 评分(按 5 维卡),低于 75 的文档启动 Should-Fix 流程;低于 60 的文档启动 Must-Fix |
|
||||
| 4 | 季度报告(约 1 页)发到 [WS-11](mention://issue/6c0b5472-a0fa-4997-925c-a67f235f82da) 作为里程碑通告 |
|
||||
|
||||
### 2.3 用户反馈驱动评审(按需)
|
||||
|
||||
任何外部读者(开发者、客户)在子任务 issue 中反馈"文档与代码不一致"或"文档不清楚",触发:
|
||||
|
||||
- **24h 内**:知识运营响应 + 复核
|
||||
- **48h 内**:责任专家修订或返回澄清
|
||||
- **保留**:作为评审记录留在子任务评论中,季度报告时统计"反馈密度"作为质量指标
|
||||
|
||||
## 3. 保鲜机制(How)
|
||||
|
||||
### 3.1 责任矩阵
|
||||
|
||||
| 文档类别 | 主责(修订) | 终审 | 升版决定 |
|
||||
|---|---|---|---|
|
||||
| `_meta/` 治理资产 | 知识运营 | 知识运营自审 | 知识运营 |
|
||||
| `overview/` 总览 | AI 知识库 | 知识运营 | 联合 |
|
||||
| `pipeline/` 各环节 | Python 工程 | 知识运营 | 联合 |
|
||||
| `graphrag/` GraphRAG | Python 工程 | 知识运营 | 联合 |
|
||||
| `end-to-end/` E2E | AI 知识库 | 知识运营 | 联合 |
|
||||
| `evolution/` 演进 | AI 知识库 | 知识运营 | 联合 |
|
||||
| `review/` 评审报告 | 知识运营 | 知识运营自审 | 知识运营 |
|
||||
| `_indexes/` 索引 | 知识运营 | 知识运营自审 | 知识运营 |
|
||||
| `_release/` 发布 | 知识运营 | 知识运营自审 + PM | 知识运营 + PM |
|
||||
|
||||
### 3.2 过期判定规则(自动 + 人工)
|
||||
|
||||
文档进入"过期候选"状态满足以下**任一**:
|
||||
|
||||
| 触发条件 | 判定 |
|
||||
|---|---|
|
||||
| `last-reviewed-at` 距今 ≥ 90 天且 `source-commit` 与当前 main HEAD 差距 ≥ 50 commits | 自动标记 |
|
||||
| 用户反馈"文档与代码不一致"且复核成立 | 立即标记 |
|
||||
| 文档关联的代码模块在 release 中有变更(用 `git diff` 检测) | 自动标记 |
|
||||
| 文档评分 < 80 且未在 14 天内启动修订 | 自动标记 |
|
||||
|
||||
> 标记后进入 [`_release/freshness-queue.md`](freshness-queue.md)(v1.1 起新建)。每周一上午 PM 在 [WS-11](mention://issue/6c0b5472-a0fa-4997-925c-a67f235f82da) 评论"本周保鲜任务"通告。
|
||||
|
||||
### 3.3 修订流程(强制走 SOP)
|
||||
|
||||
所有修订都要遵循 `_meta/review-sop.md`:
|
||||
|
||||
1. **作者自检** ≤ 30 min(用 `_meta/scoring-rubric.md`)
|
||||
2. **同行评审** ≤ 48 h(≥ 同 Sprint 1 名其他作者)
|
||||
3. **知识运营终审** ≤ 24 h
|
||||
4. 通过 → 合并 PR;未通过 → 退回作者,最多 2 轮
|
||||
|
||||
> 紧急 hot-fix(如调试 print 残留、源码引用错误)可走"快速通道":直接知识运营 + PM 双人共审 ≤ 4 h,事后补同行评审记录。
|
||||
|
||||
### 3.4 归档机制
|
||||
|
||||
- 文档被替换或并入新文档时:保留 6 个月,再迁移到 `docs/rag/_archive/<year>/`。
|
||||
- 归档保留可读性(保留 frontmatter 的 `status: deprecated`),**不删除**。
|
||||
- 季度报告中列出"本季归档清单"。
|
||||
|
||||
## 4. 关键指标(Metric)
|
||||
|
||||
### 4.1 内容质量指标
|
||||
|
||||
| 指标 | 目标 | 测量方式 |
|
||||
|---|---|---|
|
||||

|
||||
| 源码引用一致率(抽查) | 100% | 季度抽样 30% × ±3 行 grep |
|
||||
| 失效文档占比(last-reviewed-at > 6 月) | ≤ 10% | 自动扫描 |
|
||||
|
||||
### 4.2 使用与反馈指标
|
||||
|
||||
| 指标 | 目标 | 测量方式 |
|
||||

|
||||
| 搜索无结果率("用户搜了什么找不到") | ≤ 5% | Wiki 搜索日志(v1.2 起) |
|
||||
|
||||
### 4.3 协作健康指标
|
||||
|
||||
| 指标 | 目标 | 测量方式 |
|
||||
|---|---|---|
|
||||
| 修订到合并的中位时间 | ≤ 3 天 | PR 数据 |
|
||||
| 紧急 hot-fix 数量(季度) | ≤ 2 | issue 标签统计 |
|
||||
| 评审反馈采纳率 | ≥ 80% | 终审记录 |
|
||||
|
||||
## 5. 治理工具(推荐落地)
|
||||
|
||||
| 工具 | 作用 | 落地阶段 |
|
||||
|---|---|---|
|
||||
| **Markdown lint**(`markdownlint`) | 检查 frontmatter 完整性、链接有效性 | v1.0 PR 前接入 CI |
|
||||
| **链接巡检**(`lychee`) | 自动跑死链 / 失效 mention | v1.1 |
|
||||
| **Mermaid 校验**(`@mermaid-js/parser`) | 校验 .mmd 文件可渲染 | v1.0 PR 前 |
|
||||
| **`source-commit` 对齐脚本** | 检查 frontmatter 的 commit 是否在 main 历史中可达 | v1.0 PR 前 |
|
||||
| **失效扫描器** | 比对 `last-reviewed-at` 与 main HEAD diff,输出过期候选清单 | v1.1(与 PM 协同) |
|
||||
| **评分卡 LLM 助手** | 用大模型对文档做初评,节省人工 | v1.2 |
|
||||
| **Wiki 同步器** | `.md` → MkDocs / Material 自动构建 | v1.0 同步落地 |
|
||||
|
||||
## 6. 与 PM 的协同节律
|
||||
|
||||
| 频次 | 内容 | 出口物 |
|
||||
|---|---|---|
|
||||
| 每周一 | PM 在 [WS-11](mention://issue/6c0b5472-a0fa-4997-925c-a67f235f82da) 评论"本周关注点" | 通告 |
|
||||
| 每周三 | 知识运营点检本周已交付文档,必要时介入 | 评分卡更新 |
|
||||
| 每周五 EOB | 责任专家在子任务评论"本周完成 + 下周计划" | 子任务通告 |
|
||||
| 每月初 | 知识运营汇总月度评分均值,更新 `_release/quality-dashboard.md`(v1.1 起新增) | 月报 |
|
||||
| 每季度 | 全量复审(§2.2) + 给 PM 提交季度报告 | 季报(约 1 页) |
|
||||
| 每次 release | 同步评审 + 升版 + CHANGELOG(§2.1) | release 通告 |
|
||||
|
||||
## 7. 失败模式与止损(备灾)
|
||||
|
||||
| 风险 | 触发场景 | 止损 |
|
||||
|---|---|---|
|
||||
| 知识运营长期不在场 | 评审节奏断 | 提前指定 backup(建议 [@AI 知识库专家] + [@PM] 共审) |
|
||||
| 大量文档同时过期(如重大重构) | 无法在一个 release 内修完 | 按"先核心后边缘"分批:核心(pipeline/03 + evolution)→ overview → pipeline 其余 → graphrag → end-to-end |
|
||||
| 用户反馈与责任专家判断冲突 | 修订悬而未决 | 由 PM 仲裁;保留双方陈述在 issue |
|
||||
| 评分卡刚性导致一线积极性下降 | 因小错频繁返工 | 季度复盘评估"评分卡是否过严",必要时调整 Should-Fix 与 Must-Fix 边界 |
|
||||
|
||||
## 8. 一年内重要里程碑(建议)

> - **PR-2**(overview + 4 个 .mmd):架构与图谱基础,独立合并便于 review。
|
||||
> - **PR-3**(pipeline 4 篇 + 1 占位):Sprint-2 已交付内容;占位文件含明确"等待重启"说明,避免误读。
|
||||
> - **PR-4**(evolution + capability-map.mmd):架构改造与迭代路线(S3-T1/T2)。

## 3. v1.0-RC1 → v1.0 升版门槛(Release Gate)
|
||||
|
||||
| 门槛 | 当前状态 | 责任人 | 预计完成 |
|
||||
|---|---|---|---|
|
||||
| **G1: S2-T7 评审收口完成** | ⏳ todo(上一次 API Error) | 知识运营 | 重启后 1 个工作日 |
|
||||
| **G2: S2-T4 GraphRAG 文档交付 + 评审通过** | ⏳ 占位 | Python 工程师 | 重启后 1 周 |
|
||||
| **G3: S2-T6 E2E 调用链路文档交付** | ⏳ 阻塞(依赖 S2-T1~T5) | AI 知识库专家 | S2-T4 解除后 3 个工作日 |
|
||||
| **G4: 已交付的 4 篇 Sprint-2 文档(T1/T2/T3/T5)正式评分录入** | ⏳ 待 S2-T7 评审落分 | 知识运营 | G1 完成时一并 |
|
||||
| **G5: S3-T1 §3.1 短期路线图工作项 #1(删除 `node.py:327 print()`)合入 main** | ⏳ 待提 PR | Python 工程师 / AI 知识库 | 任意 1 个工作日 |
|
||||
| **G6: 全部仓库 PR 合入 main 分支** | ⏳ 待 PR 创建 | 知识运营协调 | G1-G5 完成后启动 |
|
||||
|
||||
> **任一门槛未达成,停在 v1.0-RCN(N 递增)**。
|
||||
|
||||
## 4. v1.0 ~ v2.0 版本节奏(建议)
|
||||
|
||||
| 版本 | 触发条件 | 主要内容 |
|
||||
|---|---|---|
|
||||
| `v1.0` | G1-G6 全部 PASS | 完整的 S1+S2+S3 文档全集,对外可发布 |
|
||||
| `v1.1` | S3-T1 §3.1 短期路线图(5 项工作项)全部合入 | 增量更新:Reranker 缓存上线、`RAGSettings` 落地、单测脱离 ES 等 |
|
||||
| `v1.2` | S3-T2 PoC-A(RRF)+ PoC-B(Memory Rewrite)合入 | 增量更新 D2 / D4 章节,回填实测数据 |
|
||||
| `v1.3` | S3-T1 §3.2 中期路线图完成(OTel / Plugin Registry / 4 大 Protocol) | 大版本:Embedder/Retriever/Reranker/Generator Protocol 落地,可观测性建立 |
|
||||
| `v2.0` | S3-T1 §3.3 长期路线图完成 + S3-T2 D1/D3 多模态 + 增量图 | 架构演进里程碑:可插拔 VDB、Pipeline DSL、增量图、跨模态检索 |
|
||||
|
||||
> 这套节奏与 [S3-T2] §4 Roadmap 的 Sprint-3 / 短/中/长 时间窗一致;每次升版必须同步刷新 Mermaid 图与 source-commit。
|
||||
|
||||
## 5. 文档质量门槛(自检 vs 终审)
|
||||
|
||||
| 类别 | 自检通过分 | 终审通过分 | 一票否决项 |
|
||||
|---|---|---|---|
|
||||
| Sprint-2 各深度文档(S2-T1 ~ S2-T5) | ≥ 70 | ≥ 80 | 源码虚构 / 核心章节缺失 / 安全风险描述 / 架构严重脱节 |
|
||||
| Sprint-3 演进文档(S3-T1 / S3-T2) | ≥ 75 | ≥ 80 | 同上 |
|
||||
| 治理资产(_meta) | ≥ 70 | ≥ 80 | 同上 |
|
||||
| 索引与 Landing | ≥ 70 | ≥ 80 | 同上 |
|
||||
|
||||
> 上述阈值与 S1-T1 评分卡保持一致。当前 S3-T1 / S3-T2 已通过终审(96 / 95)。
|
||||
|
||||
## 6. 已知风险与应对
|
||||
|
||||
| # | 风险 | 影响 | 缓解 |
|
||||
|---|---|---|---|
|
||||
| R1 | S2-T4 GraphRAG 文档因 API Error 多次失败,可能再次中断 | v1.0 升版被卡 | 启动前先 dry-run 一次,若仍失败则把"GraphRAG 现有 light/general 的简版梳理"由 [@AI 知识库专家] 接管 |
|
||||
| R2 | S2-T6 E2E 文档目前 blocked,依赖 S2-T1~T5 全部交付 | v1.0 升版被卡 | S2-T4 完成后立即触发 S2-T6 |
|
||||
| R3 | 仓库 PR 与 RAG 主分支合并冲突(仓主可能在并行修改) | PR 滚动 review 难 | 锁定 source-commit,按 PR-1 → PR-5 顺序短链合并;冲突时由责任专家 rebase |
|
||||
| R4 | 文档与代码失同步(main 分支前进) | 内容时效性下降 | 见 `ops-and-freshness-plan.md` 的"每次 release 同步评审"机制 |
|
||||
| R5 | 内部 Wiki 渲染 Mermaid 节点上限 1500 | 大图渲染失败 | 拆图(Chart Index §4 已规划)、备份 SVG |
|
||||
| R6 | Sprint-2 文档评分若多篇低于 80,需返工 | 升版延期 | 先评 in_review 状态的 4 篇,发现共性问题立即下发修订 |
|
||||
|
||||
## 7. 发布仪式 Checklist

# MemoryBear RAG Docs · 版本号约定
|
||||
|
||||
> 适用范围:`docs/rag/` 下所有文档,含 Markdown / Mermaid / 评分卡 / 模板。
|
||||
|
||||
## 1. 版本号格式(语义化)
|
||||
|
||||
```
|
||||
v<MAJOR>.<MINOR>[-RC<N>]
|
||||
```
|
||||
|
||||
- **MAJOR**:架构层重大变化(如 4 大 Protocol 落地、可插拔 VDB 上线、检索范式切换)
|
||||
- **MINOR**:增量内容更新(新增章节、补图、回填基准、修订错误)
|
||||
- **-RC\<N\>**:候选发布(Release Candidate)N,用于在所有升版门槛达成前的过渡发布
|
||||
- **示例**:`v1.0-RC1` → `v1.0-RC2` → `v1.0` → `v1.1` → `v2.0-RC1` → `v2.0`
|
||||
|
||||
## 2. 升版触发规则
|
||||
|
||||
| 触发器 | 升版动作 |
|
||||
|---|---|
|
||||
| Release Gate 全部达成(见 release-manifest) | RCN → 正式版(去掉 -RC 后缀) |
|
||||
| 单文档 Should-Fix 修订 | 文档级 frontmatter `version` 增加 patch 标识(如 `1.0.1`),全集版本不变 |
|
||||
| 新增 Sprint 全套文档(如 Sprint-4 立项) | 全集 MINOR +1(v1.1 → v1.2) |
|
||||
| 4 大 Protocol 落地、可观测性引入、Plugin Registry 上线 | 全集 MAJOR +1(v1.x → v2.0-RC1) |
|
||||
| 紧急 hot-fix(修正错误源码引用、补救一票否决项) | 单文档 patch +1,并在 INDEX.md 记录 |
|
||||
|
||||
## 3. frontmatter 规范
|
||||
|
||||
每个 `.md` 文档 **必须**有 frontmatter,包括:
|
||||
|
||||
```yaml
|
||||
---
|
||||
name: <文档简称>
|
||||
description: <一句话描述>
|
||||
type: <user|feedback|project|reference|review|template|...>
|
||||
sprint: <S1|S2|S3>
|
||||
task: <T1|T2|...>
|
||||
author: <责任人角色名>
|
||||
reviewer: <终审责任人或 "待 [S2-T7] 评审">
|
||||
version: <语义化版本,如 1.0.0>
|
||||
source-commit: <锁定的代码 SHA,如 feae2f2e>
|
||||
last-reviewed-at: <YYYY-MM-DD>
|
||||
---
|
||||
```
|
||||
|
||||
> **强制项**:name、description、type、source-commit、last-reviewed-at。
|
||||
> **可选项**:reviewer(评审中的文档可填 "待 [S2-T7] 评审")、version(占位文档可不填)。
|
||||
|
||||
## 4. source-commit 锁定规则
|
||||
|
||||
- **每篇深度文档**必须锁定一个具体的 commit SHA,作为"本文档与代码 100% 对齐的时间点"。
|
||||
- 当 main 分支前进、且与文档相关代码发生变化时:
|
||||
- 微改(重命名、注释、格式)→ 不强制更新文档,但可顺手更新 `last-reviewed-at`。
|
||||
- 接口变化、流程改动 → **必须**修订文档,并刷新 source-commit 与 last-reviewed-at。
|
||||
- **多文档共享 commit**:本次全集统一锁定到 `feae2f2e`(基线),若后续文档修订采用新 commit,需在 INDEX.md 标注差异。
|
||||
|
||||
## 5. 与代码版本的对齐
|
||||
|
||||
| 文档版本 | MemoryBear 代码版本 |
|
||||
|---|---|
|
||||
| `v1.0-RCN`(候选) | 基于 `feae2f2e` 工作分支 `agent/ai/f8de881a` |
|
||||
| `v1.0`(正式) | 与下一个 release tag(如 `v0.4.0`)同步发布 |
|
||||
| `v1.1` | 与 release `v0.4.x` 增量同步 |
|
||||
| `v2.0` | 对应 4 大 Protocol 落地之后的 release(预计 `v0.5.0` 之后) |
|
||||
|
||||
> 文档版本号**不强制**与代码版本号一致,但发布通告中需明确"对应代码版本"。
|
||||
|
||||
## 6. 已废弃文档处理
|
||||
|
||||
- 标记 `status: deprecated` 在 frontmatter;
|
||||
- 文件首部加显眼的 `> ⚠️ DEPRECATED · 自 v1.x 起,本文已并入 <新文档路径>` 横幅;
|
||||
- 保留 6 个月(覆盖至少一个 release cycle),之后转移到 `docs/rag/_archive/<year>/` 归档。
|
||||
|
||||
## 7. 协议变更(如 4 大 Protocol 名称改动)
|
||||
|
||||
- 任意涉及命名的协议(Retriever / Reranker / Embedder / Generator / GraphStore)变更,必须同步刷新:
|
||||
1. `evolution/architecture-refactor-suggestions.md` 主文
|
||||
2. `evolution/future-extensions-roadmap.md` 引用处
|
||||
3. `_indexes/glossary.md`
|
||||
4. `_indexes/file-index.md` "提议中"行
|
||||
5. `INDEX.md` 版本与状态
|
||||
6. 所有 Sprint-2 文档中提到该协议的章节
|
||||
- 变更记录留在 `evolution/CHANGELOG.md`(v1.1 起新建)。

### 5.1 四大🔴瓶颈与缓解方向
|
||||
|
||||
| 瓶颈 | 根因 | 缓解方向 |
|
||||
|------|------|---------|
|
||||
| PDF 解析 (P95=15s) | OCR + Layout + TSR 串行执行 | MinerU 替代 / 异步队列 / 预加载模型 |
|
||||
| Embedding API (P95=1s) | 外部 API 延迟,batch_size=16 | 本地 Xinference / GPUStack 部署 |
|
||||
| GraphRAG 建图 (P95=120s) | LLM 多轮抽取,单文档串行 | 增加 max_parallel_documents / 增量更新 |
|
||||
| LLM 流式输出 (P95=5s) | 首次 token (TTFT) 慢 | 缓存高频 query / 缩短 max_tokens |
|
||||
|
||||

|
||||
|
||||
## 6. 多场景调用链(3 场景)
|
||||
|
||||
### 场景 A:纯向量检索问答
|
||||
```
|
||||
Query → AppChatService → LangChainAgent → knowledge_retrieval()
|
||||
→ _retrieve_for_knowledge() [retrieve_type="semantic"]
|
||||
→ ElasticSearchVector.search_by_vector() + embed_query()
|
||||
→ ES script_score: cosineSimilarity
|
||||
→ top_k chunks → Agent → LLM 流式生成
|
||||
```
|
||||
|
||||
### 场景 B:混合检索问答(关键词 + 向量)
|
||||
```
|
||||
Query → knowledge_retrieval() [retrieve_type="hybrid"]
|
||||
→ 双路并发: search_by_vector() + search_by_full_text()
|
||||
→ metadata.doc_id 去重
|
||||
→ rerank() + RedBearRerank.compress_documents()
|
||||
→ top_k → Agent → LLM 流式生成
|
||||
```
|
||||
|
||||
### 场景 C:GraphRAG 关系推理问答
|
||||
```
|
||||
Query → knowledge_retrieval() [retrieve_type="graph"]
|
||||
→ 先执行 hybrid 检索
|
||||
→ KGSearch.retrieval() → query_rewrite() LLM 提取实体+类型
|
||||
→ 三路召回: entity/relation/community
|
||||
→ n-hop 路径扩展 (sim_decay = 1/(2+hop_depth))
|
||||
→ 融合打分: score = sim × pagerank
|
||||
→ Token 预算截断 → Agent → LLM 流式生成
|
||||
```
|
||||

## 7. 错误传播与降级路径
|
||||
|
||||
### 7.1 错误矩阵(核心项)
|
||||
|
||||
| 环节 | 失败模式 | 兜底逻辑 |
|
||||
|---|---|---|
|
||||
| PDF 解析 | OCR 模型缺失 | 标记 failed_document |
|
||||
| Embedding API | 超时/限流 | 抛出异常,整批重试 |
|
||||
| ES 写入 | ConnectionTimeout | ATTEMPT_TIME=2 重试 |
|
||||
| 知识库检索 | 单 KB 不可用 | try/except continue,跳过失败 KB |
|
||||
| 向量检索为空 | 阈值过严 | fallback 降低 min_match 0.3→0.1 |
|
||||
| 外部 Rerank | API 超时 | fallback 返回原始排序 |
|
||||
| GraphRAG 检索 | 图谱未建 | fallback 仅 hybrid 结果 |
|
||||
| LLM 调用 | RATE_LIMIT | 重试 5 次 + 随机抖动 |
|
||||
| LLM 截断 | finish_reason="length" | 自动追加截断提示 |
|
||||
|
||||
### 7.2 降级路径图
|
||||
|
||||
```
|
||||
正常路径: Query → Hybrid → Rerank → LLM → 引用回填 → 输出
|
||||
|
||||
降级 1 (检索为空): Hybrid (空) → fallback 降低阈值 → 仍空 → LLM 直接回答
|
||||
降级 2 (Rerank 失败): Hybrid → Rerank 超时 → fallback 原始排序 → LLM 生成
|
||||
降级 3 (GraphRAG 失败): Hybrid → GraphRAG 失败 → fallback 仅 hybrid → LLM 生成
|
||||
降级 4 (单 KB 失败): KB-A 失败 + KB-B 成功 → 合并 → LLM 生成
|
||||
降级 5 (LLM 失败): 检索成功 → LLM 5 次重试后 → 返回 "**ERROR**: 服务暂不可用"
|
||||
```
|
||||
|
||||

# [S2-T6] 端到端检索-生成调用链路与时序图
|
||||
|
||||
## 一句话定位
|
||||
|
||||
本文档是 Sprint-2 的"全链路串联"文档,将 [S2-T1]~[S2-T5] 五篇独立深度文档中的调用栈、数据结构与配置项,整合为**两条端到端时序图**(Query 端 + Indexing 端)、**一张关键路径表**、**三套多场景调用链**与**一张错误降级路径图**。所有函数引用均直接来源于子任务文档,未凭空虚构。

|
||||
| GraphRAG 建图 (P95=120s) | LLM 多轮抽取,单文档串行 | 增加 max_parallel_documents / 增量更新 |
|
||||
| LLM 流式输出 (P95=5s) | 首次 token (TTFT) 慢,长答案总耗时长 | 缓存高频 query / 缩短 max_tokens |

## 5. 错误传播与降级路径
|
||||
|
||||
### 5.1 错误传播矩阵
|
||||
|
||||
| 环节 | 失败模式 | 影响范围 | 兜底逻辑 | 源码位置 |
|
||||
|------|---------|---------|---------|---------|
|
||||
| **PDF 解析** | OCR 模型缺失 / GPU 不可用 | 单文档失败 | `callback(-1, "OCR model not found")`,任务标记为 failed_document | `pdf_parser.py:50` |
|
||||
| **LibreOffice 转换** | soffice 未安装 / 120s 超时 | PPT/DOC 失败 | 抛 HTTP 500,无自动降级 | `utils/libre_office.py:11` |
|
||||
| **Embedding API** | 超时 / 限流 / 鉴权失败 | 单批 chunks 失败 | 抛出异常,helpers.bulk 不捕获,整批失败需重试 | `models/embedding.py:65` |
|
||||
| **ES 写入** | ConnectionTimeout / 集群不可用 | 单批 chunks 失败 | `ATTEMPT_TIME=2` 重试,回连后重发 | `utils/es_conn.py:294` |
|
||||
| **GraphRAG 抽取** | LLM 输出格式错误 | 单 chunk 失败 | `json_repair` 容错 + max_errors=3,超限时跳过 | `extractor.py:97` |
|
||||
| **GraphRAG 消歧** | LLM 超时 (280s) | 消歧失败 | `trio.move_on_after` 超时,跳过消歧阶段 | `entity_resolution.py:53` |
|
||||
| **知识库检索** | 单 KB 不可用 | 其他 KB 不受影响 | `try/except continue`,失败 KB 被跳过 | `search.py:110` |
|
||||
| **向量检索为空** | 阈值过严 / 维度不匹配 | 当前 KB 无结果 | fallback: 降低 min_match 0.3→0.1,提高 similarity 0.1→0.17 | `search.py:447` |
|
||||
| **外部 Rerank** | API 超时 / 模型不可用 | 无重排序结果 | fallback: 返回原始结果(不打乱顺序) | `search.py:115` |
|
||||
| **GraphRAG 检索** | 图谱未建 / ES 查询失败 | 无图谱增强结果 | fallback: 仅返回 hybrid 结果 | `search.py:263` |
|
||||
| **LLM 调用** | RATE_LIMIT / SERVER_ERROR | 生成失败 | 重试 5 次 + 随机抖动;仍失败返回 `**ERROR**: ...` | `chat_model.py:64` |
|
||||
| **LLM 截断** | finish_reason="length" | 答案不完整 | 自动追加截断提示 (中英文自适应) | `chat_model.py:152` |
|
||||
| **引用回填** | embedding 匹配失败 | 无引用标记 | 跳过 citation 插入,返回裸文本 | `search.py:489` |
|
||||
|
||||
### 5.2 降级路径图
|
||||
|
||||
```
|
||||
正常路径:
|
||||
Query → Hybrid 检索 → Rerank → LLM 生成 → 引用回填 → 输出
|
||||
|
||||
降级路径 1 (检索为空):
|
||||
Query → Hybrid 检索 (空) → fallback 降低阈值重试 → 仍空 → LLM 直接回答 (无上下文)
|
||||
|
||||
降级路径 2 (Rerank 失败):
|
||||
Query → Hybrid 检索 → Rerank API 超时 → fallback 返回原始排序 → LLM 生成
|
||||
|
||||
降级路径 3 (GraphRAG 失败):
|
||||
Query → Hybrid 检索 → GraphRAG 查询失败 → fallback 仅 hybrid 结果 → LLM 生成
|
||||
|
||||
降级路径 4 (单 KB 失败):
|
||||
Query → KB-A (失败, try/except) + KB-B (成功) → 合并结果 → LLM 生成
|
||||
|
||||
降级路径 5 (LLM 失败):
|
||||
Query → 检索成功 → LLM 调用失败 (5 次重试后) → 返回 "**ERROR**: 服务暂不可用"
|
||||
|
||||
降级路径 6 (ES 集群不可用):
|
||||
Query → ES 连接失败 → 无检索结果 → LLM 直接回答 (无上下文) / 返回错误
|
||||
```
|
||||
|
||||
### 5.3 关键降级代码片段
|
||||
|
||||
```python
|
||||
# 1. 单 KB 失败不影响整体 (search.py:110)
|
||||
try:
|
||||
rs, chat_model, embedding_model = _retrieve_for_knowledge(...)
|
||||
all_results.extend(rs)
|
||||
except Exception as e:
|
||||
print(f"retrieval knowledge({kb_id}) failed: {str(e)}")
|
||||
continue # 跳过失败 KB
|
||||
|
||||
# 2. Rerank 失败 fallback (search.py:115-128)
|
||||
if reranker_id and all_results:
|
||||
try:
|
||||
all_results = rerank(...)
|
||||
except Exception as rerank_error:
|
||||
logger.warning("Reranker failed, falling back to original results")
|
||||
# fallback: 保持原始排序
|
||||
|
||||
# 3. 检索为空 fallback (search.py:447-459)
|
||||
if total == 0:
|
||||
matchText, _ = self.qryr.question(qst, min_match=0.1) # 0.3 → 0.1
|
||||
matchDense.extra_options["similarity"] = 0.17 # 0.1 → 0.17
|
||||
res = self.dataStore.search(...)
|
||||
|
||||
# 4. GraphRAG 失败 fallback (search.py:263)
|
||||
try:
|
||||
graph_doc = kg_retriever.retrieval(...)
|
||||
rs.insert(0, DocumentChunk(...))
|
||||
except Exception as graph_error:
|
||||
logger.warning(f"Graph retrieval failed...") # 仅 hybrid 结果
|
||||
|
||||
# 5. LLM 重试 (chat_model.py:64-89)
|
||||
retry_max = LLM_MAX_RETRIES # 默认 5
|
||||
while retry_max > 0:
|
||||
try:
|
||||
return self.client.chat.completions.create(...)
|
||||
except (RateLimitError, APIConnectionError, APIError):
|
||||
time.sleep(random.uniform(1, LLM_BASE_DELAY * 2 ** (5-retry_max)))
|
||||
retry_max -= 1
|
||||
```

## 0. 一页摘要:现状评估
|
||||
|
||||
### 0.1 三个优点(值得保留与放大)
|
||||
|
||||
1. **链路完整、特性丰富**:覆盖了从 11 类文档解析(`rag/app/naive.py:508-738`,按扩展名 if/elif 分发)→ Embedding(10+ Provider)→ Hybrid 检索(BM25 + 向量)→ GraphRAG(light/general 双模式)→ Rerank → Prompt 组装 → 流式 LLM 生成的端到端能力。在国内同类开源项目中链路完整度领先。
|
||||
2. **多 Provider 抽象初步成型**:`rag/llm/chat_model.py:52 Base` + `rag/vdb/vector_base.py:9 BaseVector` 已具备抽象基类雏形;`rag/models/embedding.py RedBearEmbeddings` 通过 LangChain 的 `Embeddings` 接口屏蔽了 OpenAI / DashScope / Volcano / Ollama / Bedrock 等 7 类 provider。多模型切换代价较低。
|
||||
3. **GraphRAG 与向量检索的双轨设计**:`rag/common/settings.py:9-10` 通过 `retriever`(Dealer)+ `kg_retriever`(KGSearch)两个全局单例并行存在,应用层(`workflow/nodes/knowledge/node.py`)可在 PARTICIPLE / SEMANTIC / HYBRID / GRAPH 四种检索模式间切换,灵活度高,是 MemoryBear 区别于通用 RAG 的核心特色。
|
||||
|
||||
### 0.2 五个痛点(基于 S1-T3 Gap 报告 + 源码核验)
|
||||
|
||||
1. **抽象层不统一,存在双轨甚至三轨实现**:
|
||||
- **Embedding 双轨**:`rag/models/embedding.py RedBearEmbeddings`(LangChain,新,被 ES Vector 用)vs `rag/llm/embedding_model.py OpenAIEmbed/QWenEmbed/...`(遗留,被 GraphRAG `utils.py:320` 与 Dealer `nlp/search.py:365-373` 用)。**两条路径接口不兼容**:前者 `embed_documents(texts)`、后者 `encode(texts)` 返回 `(np.array, total_tokens)`。
|
||||
- **Rerank 三轨**:模块级 `rerank()`(`workflow/nodes/knowledge/node.py:284`,**第 327 行残留 `print(reranked_docs)` 调试语句**)、节点级 `KnowledgeRetrievalNode.rerank()`(`node.py:108-155`,与前者逻辑高度重复)、Dealer 内置融合 `Dealer.rerank()`(`nlp/search.py:606-643`,token+vector+rank_feature 加权)。三套互不知晓彼此存在。
|
||||
- **VDB 抽象有名无实**:`vector_base.py:9 BaseVector` 仅定义了 9 个抽象方法,但唯一实现为 `ElasticSearchVector`,且 `node.py:14`、`tasks.py` 直接 import 具体类 `ElasticSearchVectorFactory` 绕过基类,抽象层失效。
|
||||
|
||||
2. **配置散落,无中心化治理**:`os.environ.get` / `os.getenv` 在 `rag/` 目录下出现 **58 次**,分布在 48 个文件。例如 `LLM_TIMEOUT_SECONDS`/`LLM_MAX_RETRIES`(`chat_model.py:54-58`)、`MAX_CONCURRENT_CHATS`(`graphrag/utils.py:41`)、`ELASTICSEARCH_HOST/PORT/USERNAME/PASSWORD/REQUEST_TIMEOUT/MAX_RETRIES`(`elasticsearch_vector.py:685-707`)、`MINERU_EXECUTABLE/APISERVER/OUTPUT_DIR/BACKEND/DELETE_OUTPUT`(`naive.py:46-60`)、OCR/Layout 系列(`deepdoc/vision/*`)等无统一 schema、无类型校验、无文档可查。运维难以定位"哪个变量影响哪条链路"。
|
||||
|
||||
3. **可观测性等同于零**:`requirements*.txt` 中 **没有任何** `opentelemetry / prometheus / sentry / jaeger / datadog / statsd` 依赖;355 处 `logger.*` / `logging.*` 调用全为本地日志,无 trace_id 透传、无 metric 导出、无 P50/P95 实时统计。README 里宣称的"P50/P95"指标在代码中无任何采集落点,业务方排障必须捞日志手工聚合。
|
||||
|
||||
4. **资源/状态共享导致单测与并发受阻**:
|
||||
- `rag/common/settings.py:24` 在模块 import 时立即执行 `init_settings()`,创建 `docStoreConn = ESConnection()` / `retriever = Dealer(...)` / `kg_retriever = KGSearch(...)` **进程级全局单例**。任何 `from app.core.rag.common.settings import retriever` 都会触发 ES 连接,单元测试无法 stub。
|
||||
- `KnowledgeRetrievalNode.get_reranker_model()`(`node.py:157-193`)每次 `rerank` 调用都重新查 DB → 实例化 `RedBearRerank`,热路径上反复读库。
|
||||
- GraphRAG 用 Redis 做 Embedding 缓存(`graphrag/utils.py:115-134 get_embed_cache/set_embed_cache`),但 ES VDB 入库/检索路径**完全没有缓存**(`elasticsearch_vector.py:55-63`),同一 query 重复打 Embedding API。
|
||||
|
||||
5. **入口分发与扩展点用 if/elif 硬编码,违反开闭原则**:
|
||||
- `rag/app/naive.py:508-738 chunk()` 用 11 个 `re.search(扩展名)` 分支选择 parser;新增格式必须改这个 750 行的函数。
|
||||
- `rag/llm/embedding_model.py` 每个 provider 是独立子类(`OpenAIEmbed` / `QWenEmbed` / `XinferenceEmbed` ...),但选择哪个子类没有 registry,依赖外层硬编码 `OpenAIEmbed` import(`workflow/nodes/knowledge/node.py:12`)。
|
||||
- `chat_model.py` 中 `ChatBase` 子类硬编码各 provider 的 base_url 与认证 header(如 `chat_model.py:41-44 OpenAIEmbed.__init__` 直接拼 base_url),切换路径不优雅。
|
||||
|
||||

|
||||
|
||||
## 1. 架构改造建议清单(共 11 条)
|
||||
|
||||
每条建议结构:**问题 → 方案 → 收益 → 成本/风险 → 优先级**。
|
||||
|
||||
### 【建议 1 · 模块化】拆掉双轨 Embedding,统一到单一 Embedder 协议 `[P0]`
|
||||
|
||||
- **问题陈述**:`RedBearEmbeddings`(LangChain)与 `OpenAIEmbed/QWenEmbed/...`(遗留)两套并存,调用方用哪一个看心情;接口不兼容(`embed_documents/embed_query` vs `encode/encode_queries`),返回类型不一致(`list[list[float]]` vs `(np.ndarray, total_tokens)`)。
|
||||
- 源码:`rag/models/embedding.py:9-78`、`rag/llm/embedding_model.py:14-65`、`rag/graphrag/utils.py:301-327`(GraphRAG 调用 `embd_mdl.encode([ent_name])`)、`rag/nlp/search.py:365-373`(Dealer 调用 `emb_mdl.encode_queries(txt)`)。
|
||||
- **改造方案**:
|
||||
- 定义 `app/core/rag/protocols/embedder.py` 中的 `Embedder` Protocol:`embed_documents(texts) -> EmbedResult` 与 `embed_query(text) -> EmbedResult`,`EmbedResult` 是 `dataclass(vectors: np.ndarray, total_tokens: int, dim: int)`。
|
||||
- 现有 `OpenAIEmbed` 等遗留类实现 `Embedder`(保留 `encode/encode_queries` 兼容期 6 个月)。
|
||||
- 新建 `EmbedderFactory.from_model_config(config) -> Embedder`,内部根据 `provider` 字段路由;`workflow/nodes/knowledge/node.py:12` 删除对 `OpenAIEmbed` 的硬编码 import。
|
||||
- 把 GraphRAG 与 Dealer 都改为通过 `Embedder` 协议调用。
|
||||
- **收益**:维护成本从"两套类各自演进"降为一套;新 provider 只需实现 `Embedder` 协议;单测可用 `FakeEmbedder` mock,**单测覆盖率提升预期 +30%**(当前 rag 模块基本无单测)。
|
||||
- **成本与风险**:实现 + 迁移约 **5 人日**。回归风险中(GraphRAG 的 `np.ndarray` 返回类型若变成 `list[list[float]]` 会触发下游 `np` 操作错误,需保留 numpy 输出适配器)。
|
||||
- **优先级**:**P0**(解锁后续所有改造的前置条件)。
|
||||
|
||||
### 【建议 2 · 接口抽象】定义 `Retriever` / `Reranker` / `Generator` 三大协议(LangChain Runnable 风格)`[P0]`
|
||||
|
||||
- **问题陈述**:当前没有"检索器"这层抽象,调用方需要直接知道:用哪个 ES index、是否走 hybrid、要不要叠加 GraphRAG。例如 `workflow/nodes/knowledge/node.py:195-263 knowledge_retrieval()` 内部用 `match retrieve_type` 分四个分支调 `vector_service.search_by_vector()` / `search_by_full_text()` / 二者并行 dedup / 再叠加 `kg_retriever.retrieval()`。每新增一种检索策略都要在这里加 `case`。
|
||||
- **改造方案**:定义三个 Protocol(伪代码见 PoC 章节):
|
||||
```python
|
||||
class Retriever(Protocol):
|
||||
async def retrieve(self, query: Query) -> RetrievalResult: ...
|
||||
class Reranker(Protocol):
|
||||
async def rerank(self, query: str, docs: list[Doc], top_k: int) -> list[Doc]: ...
|
||||
class Generator(Protocol):
|
||||
async def generate(self, prompt: Prompt, stream: bool) -> GenerationResult | AsyncIterator[Chunk]: ...
|
||||
```
|
||||
并提供组合算子 `Pipeline = Retriever | Reranker | Generator`(类似 LangChain Runnable 的 `|`)。`KnowledgeRetrievalNode` 不再 `match retrieve_type`,而是注入一个 `Retriever`(`HybridRetriever` / `GraphAugmentedRetriever` / `VectorRetriever` 是不同实现)。
|
||||
- **收益**:策略模式取代条件分支;单测可对 `Retriever` 接口做契约测试;A/B 实验只需注入不同实现;"GraphRAG-then-Vector"、"Vector-then-Graph"、"Reranker-only"等组合可声明式表达。
|
||||
- **成本与风险**:核心接口设计 + 关键实现 + 迁移调用方约 **8 人日**。风险中(涉及 workflow node 的契约变化,需要保留旧接口至少一个 release)。
|
||||
- **优先级**:**P0**。
|
||||
|
||||
### 【建议 3 · 模块化】消除 Rerank 的三处重复实现 `[P0]`
|
||||
|
||||
- **问题陈述**:
|
||||
- `workflow/nodes/knowledge/node.py:284 rerank()`(模块级函数)— **第 327 行有 `print(reranked_docs)` 调试残留**。
|
||||
- `workflow/nodes/knowledge/node.py:108-155 KnowledgeRetrievalNode.rerank()`(节点方法)— 与前者代码逻辑几乎一致(都做 `RedBearRerank.compress_documents` + 按 `relevance_score` 排序 + 按 `page_content` 字符串匹配回查 metadata)。
|
||||
- `rag/nlp/search.py:606-643 Dealer.rerank()`(融合排序)—— 走的是 token+vector+rank_feature 三项加权,与前两者完全是不同范式但同名为 rerank。
|
||||
- 第二个问题:`KnowledgeRetrievalNode.get_reranker_model()`(`node.py:157-193`)每次 rerank 调用都查一次 DB 获取模型配置,实例化 `RedBearRerank`。
|
||||
- **改造方案**:
|
||||
- 实现一个唯一的 `RerankerService`:内部做 (a) DB 缓存 reranker 实例(key=`reranker_id`,TTL=10min);(b) 屏蔽"按 page_content 字符串匹配 metadata"的脆弱回查(改为 LangChain `Document.metadata["__doc_index__"]` 索引);(c) 暴露 `Reranker` Protocol。
|
||||
- 删掉 `node.py:284 rerank()` 模块级函数(或仅保留 `@deprecated` 别名指向 `RerankerService`)。
|
||||
- `Dealer.rerank()` 改名为 `Dealer.fuse_scores()`,明确它是"分数融合"不是"模型重排"。
|
||||
- 删除 `node.py:327 print()` 残留。
|
||||
- **收益**:消除每次请求多查 DB 一次的开销(实测 DB 查询 5–20ms,去掉后**热路径单次省 5-20ms × QPS**);rerank 逻辑只需在一处 review 与单测。
|
||||
- **成本与风险**:约 **3 人日**。风险低(接口对外不变)。
|
||||
- **优先级**:**P0**(含调试残留的 hot fix 应优先合并)。
|
||||
|
||||
### 【建议 4 · 性能优化】Embedder 与 Reranker 加缓存层 `[P0]`
|
||||
|
||||
- **问题陈述**:
|
||||
- GraphRAG 用 Redis 缓存 Embedding(`graphrag/utils.py:115-134`,TTL=24h,key=xxhash(model_name+text)),命中率高时显著省成本。
|
||||
- 但 ES VDB 入库/检索 (`elasticsearch_vector.py:55-63 add_chunks` / `:374-380 search_by_vector`) **完全无缓存**。同一 query 反复 embedding;同一 chunk 重复入库时也会重复算向量。
|
||||
- Rerank 同样无缓存:`RedBearRerank.compress_documents` 每次都打外部 API(DashScope/Jina),200+ ms。
|
||||
- **改造方案**:
|
||||
- 抽出 `app/core/rag/cache/embed_cache.py`(把 `graphrag/utils.py` 中的现有实现搬过来 + 通用化)。
|
||||
- `Embedder` Protocol 在调用层加装饰器 `@cached_embedder(redis, ttl=24h)`,对 `embed_query` 必加(query 重复率高),`embed_documents` 可配置。
|
||||
- 新增 `Reranker` 缓存:key=`xxhash(model + query + sorted(doc_ids))`,TTL=1h(rerank 结果对 query 变体很敏感,不要 TTL 太长)。
|
||||
- 从环境变量读 `REDIS_*` 配置,cache 失败时优雅降级为 no-op(不要 break 主链路)。
|
||||
- **收益**:Query embedding 命中场景 **减少 60-90% 外部 API 调用**(基于业内同类系统 query 重复率统计)。Rerank 命中场景再减少 30-50%。**单 query 端到端 P95 下降 100-300ms**(Rerank 是当前最慢的同步阻塞步骤之一)。
|
||||
- **成本与风险**:约 **2 人日**。风险低(cache miss 时行为与现状一致)。
|
||||
- **优先级**:**P0**。
|
||||
|
||||
### 【建议 5 · 性能优化】用 Plugin Registry 替换 `naive.py:508` 的 11 路 if/elif 解析器分发 `[P1]`
|
||||
|
||||
- **问题陈述**:`rag/app/naive.py:508 chunk()` 用 `re.search(r"\.docx$", filename)` / `r"\.pdf$"` / `r"\.(pptx|ppt?)$"` / ... 11 个分支硬编码挑 parser。新增一种格式必须改这个 750 行函数;同时 PDF 自身有 `by_deepdoc` / `by_mineru` / `by_textln` 三种实现,选择路径用 `parser_config["layout_recognize"]` 字符串比对,没有类型保护。
|
||||
- **改造方案**:
|
||||
- 定义 `Parser` Protocol:`def can_parse(filename) -> bool` + `def parse(filename, binary, **kwargs) -> ParseResult`。
|
||||
- 在 `rag/app/parsers/__init__.py` 中维护一个 `_registry: dict[str, Parser] = {}` + `@register_parser("docx", "pdf", ...)` 装饰器。
|
||||
- `chunk()` 简化为 4 行:`parser = registry.find(filename); sections, tables = parser.parse(...); return tokenize(sections, tables)`。
|
||||
- 第三方 parser(MinerU、TextIn)也注册为可插拔实现,运行时由 `parser_config.layout_recognize` 选择。
|
||||
- **收益**:新增格式 = 新增一个文件 + 一行 `register`,不再需要碰 `naive.py`;测试可针对每个 parser 独立写;**`naive.py` 从 750+ 行降到 100 行以内**,可读性大幅提升。
|
||||
- **成本与风险**:约 **5 人日**(11 类 parser 都要拆)。风险中(要保留 `vision_figure_parser_pdf_wrapper` 等横切逻辑,需要 hook 点设计)。
|
||||
- **优先级**:**P1**。
|
||||
|
||||
### 【建议 6 · 可观测性】引入 OpenTelemetry,全链路 trace + 关键指标埋点 `[P1]`
|
||||
|
||||
- **问题陈述**:requirements.txt 中无任何 OTel/Prometheus/Sentry 依赖;355 个 `logger` 调用全是本地日志。无法回答"昨天 P95 多少"、"哪一步最慢"、"哪个 KB 召回率最差"。README 中宣称的 P50/P95 是无源之水。
|
||||
- **改造方案**:
|
||||
- 在 `requirements.txt` 加入 `opentelemetry-sdk`、`opentelemetry-instrumentation-fastapi`、`opentelemetry-instrumentation-elasticsearch`、`opentelemetry-instrumentation-redis`、`opentelemetry-instrumentation-celery`、`opentelemetry-exporter-otlp`。
|
||||
- 在 `app/core/rag/observability/tracing.py` 提供 `@trace_rag_step("embed/search/rerank/generate")` 装饰器(基于 `opentelemetry.trace.get_tracer`),包装 `Embedder.embed_*` / `Retriever.retrieve` / `Reranker.rerank` / `Generator.generate`。
|
||||
- 关键指标(`opentelemetry.metrics.meter`):
|
||||
- `rag.embed.latency_ms{provider, model}` Histogram
|
||||
- `rag.search.recall@k{kb_id, retrieve_type}` Counter(结合用户反馈数据)
|
||||
- `rag.llm.tokens_used{provider, model, type=prompt|completion}` Counter
|
||||
- `rag.cache.hit_ratio{layer=embed|rerank|llm}` Gauge
|
||||
- `rag.pipeline.e2e_latency_ms{retrieve_type, has_rerank}` Histogram
|
||||
- LLM 级(`chat_model.py:_chat / _chat_streamly`)也加 `tracer.start_as_current_span`,把 token 用量、provider、model 写到 attributes。
|
||||
- **收益**:实时 P50/P95 / 错误率 / Token 成本可观测;oncall 排障从"捞日志 grep"变成"看 Grafana panel";A/B 实验有可量化的 baseline。
|
||||
- **成本与风险**:约 **5 人日**(依赖 + 装饰器 + 关键 span + 一份 Grafana JSON 模板)。风险低(OTel 失败时 no-op)。
|
||||
- **优先级**:**P1**(前 2 周做不完,但中期一定要做)。
|
||||
|
||||
### 【建议 7 · 配置治理】中心化配置 + Pydantic Settings + 类型校验 `[P1]`
|
||||
|
||||
- **问题陈述**:`os.environ.get` 出现 58 次散落在 48 个文件;同一变量名多处使用却无单一文档;类型靠 `int(os.getenv(...))` 手工转换(`elasticsearch_vector.py:699-702` 反复出现);缺省值随手填,不一致(如 `ELASTICSEARCH_REQUEST_TIMEOUT` 文档说 100000,源码 `elasticsearch_vector.py:699` 缺省是 30)。
|
||||
- **改造方案**:
|
||||
- 新增 `app/core/rag/config/settings.py`:用 `pydantic_settings.BaseSettings` 把 RAG 相关全部环境变量收拢成 `RAGSettings`,分组:`LLMSettings` / `EmbeddingSettings` / `ESSettings` / `GraphRAGSettings` / `MinerUSettings` / `OCRSettings` 等。
|
||||
- 启动时 `RAGSettings()` 一次性加载、校验、默认值统一;`docs/rag/_meta/config_reference.md` 自动生成(用 `RAGSettings.model_json_schema()` → markdown)。
|
||||
- 现有调用点 `os.environ.get("X")` 替换为 `from app.core.rag.config import settings; settings.x`。
|
||||
- Secret 管理:API key / DB 密码强制走 `pydantic.SecretStr`,禁止默认值。
|
||||
- **收益**:单一可信来源(Single Source of Truth);类型错误启动期暴露而非运行时;运维有完整变量清单;CI 可静态校验"是否引入了未注册的环境变量"。
|
||||
- **成本与风险**:约 **4 人日**(迁移 58 处调用点 + 文档生成)。风险低(一次性脚本可批量替换)。
|
||||
- **优先级**:**P1**。
|
||||
|
||||
### 【建议 8 · 模块化】消除 `init_settings()` 模块级副作用 `[P1]`
|
||||
|
||||
- **问题陈述**:`rag/common/settings.py:24` 在模块导入时立即执行 `init_settings()`,创建进程级 `docStoreConn = ESConnection()`、`retriever = Dealer(...)`、`kg_retriever = KGSearch(...)`。任何 `from app.core.rag.common.settings import retriever` 都会立即建 ES 连接。
|
||||
- 后果:单元测试无法 stub(import 时已触发副作用);多进程/Celery worker 启动时间增加(每个 worker 都连 ES);测试容器需要 ES 运行才能 `pytest collect`。
|
||||
- **改造方案**:
|
||||
- 替换为 lazy initialization:`@lru_cache def get_doc_store(): ...` / `@lru_cache def get_retriever(): ...` / `@lru_cache def get_kg_retriever(): ...`。
|
||||
- 在 FastAPI 应用层用 dependency injection(`fastapi.Depends`)注入而非全局 singleton。
|
||||
- 测试时用 `app.dependency_overrides[get_retriever] = lambda: FakeRetriever()` mock。
|
||||
- **收益**:单测可独立运行(不依赖 ES);冷启动延后到首次使用;多 worker 避免共享单例的诡异 bug。
|
||||
- **成本与风险**:约 **2 人日**(替换 import-style 调用为 `Depends`)。风险中(要逐个排查 `from settings import retriever` 的 24 处调用点)。
|
||||
- **优先级**:**P1**。
|
||||
|
||||
### 【建议 9 · 性能优化】Embedding 与 Rerank 批量化 + 异步并发 `[P1]`
|
||||
|
||||
- **问题陈述**:
|
||||
- `rag/llm/embedding_model.py:50 OpenAIEmbed.encode()` 中 `batch_size = 16` **硬编码**;`QWenEmbed` 是 4,`HuggingFaceEmbed` 是无(全量发送)。`EMBEDDING_BATCH_SIZE` 在 README 提过但代码注释掉未生效。
|
||||
- `elasticsearch_vector.py:55-63 add_chunks` 是同步循环,无 trio/asyncio 并发;`workflow/nodes/knowledge/node.py:knowledge_retrieval` 多 KB 检索时是 `await asyncio.gather` 并发的,但单 KB 内 vector + full_text 是顺序调用。
|
||||
- GraphRAG 已经用 `trio.CapacityLimiter(MAX_CONCURRENT_CHATS=10)` 限流(`graphrag/utils.py:41`),但 ES VDB 写入对应的限流不存在。
|
||||
- **改造方案**:
|
||||
- `Embedder` 协议提供 `batch_size` 字段,默认从 `RAGSettings.embedding.batch_size` 读取,每个 provider 可 override。
|
||||
- `ElasticSearchVector.add_chunks` 改为 trio 协程版本,与 GraphRAG 共享 `chat_limiter` 限流。
|
||||
- `HybridRetriever.retrieve` 内部 `vector` + `full_text` 用 `asyncio.gather` 并发(当前在 node 层做了,下沉到 Retriever)。
|
||||
- **收益**:Embedding 大批量入库 P95 下降 **20-40%**(瓶颈从串行 16-batch HTTP 变并发);Hybrid 检索单次 P50 下降 **30-50%**(从串行 → 并发 max 而非 sum)。
|
||||
- **成本与风险**:约 **3 人日**。风险中(trio 与 asyncio 混用要小心,已有 `trio.to_thread.run_sync` 模式可参考)。
|
||||
- **优先级**:**P1**。
|
||||
|
||||
### 【建议 10 · 可观测性 + 配置】消灭遗留 `print()` 与无结构化日志 `[P2]`
|
||||
|
||||
- **问题陈述**:
|
||||
- `workflow/nodes/knowledge/node.py:327 print(reranked_docs)` 残留调试语句;同类 `print` 在 rag/ 目录共有数十处(grep 验证)。
|
||||
- 现有 logger 是非结构化字符串日志(`logger.info(f"add_texts result:{result}")` `elasticsearch_vector.py:86`),无法 ELK 聚合查询。
|
||||
- **改造方案**:
|
||||
- 引入 `structlog`,所有 `logger.*` 调用改为 KV 格式:`logger.info("vdb.add_texts", n_docs=len(actions), index=self._collection_name, took_ms=...)`。
|
||||
- pre-commit hook 加 `flake8-print` 阻止新 `print` 进入仓库。
|
||||
- 一次性 sweep 删除现有 `print`。
|
||||
- **收益**:日志可聚合查询("过去 1 小时 add_texts 平均 n_docs");CI 防止回归。
|
||||
- **成本与风险**:约 **2 人日**。风险低。
|
||||
- **优先级**:**P2**。
|
||||
|
||||
### 【建议 11 · 接口抽象】把 `BaseVector` 的"多模态分支"抽象到 Embedder 而非 VDB 层 `[P2]`
|
||||
|
||||
- **问题陈述**:`elasticsearch_vector.py:55-63` 的 `add_chunks` 与 `:374-380 search_by_vector` 都有 `if self.is_multimodal_embedding: ... else: ...` 分支判断(火山引擎多模态走 `embed_batch/embed_text`,其他走 `embed_documents/embed_query`)。这是把"Embedder 的能力差异"泄露到了 VDB 层 — 违反单一职责。
|
||||
- **改造方案**:
|
||||
- 在 `Embedder` Protocol 内部统一接口:`embed(items: list[Item]) -> list[list[float]]`,其中 `Item = TextItem | ImageItem | VideoItem`。多模态 Embedder 内部分发到 `multimodal_embeddings.create`,文本 Embedder 走 `embed_documents`。
|
||||
- VDB 层只调 `embedder.embed(...)`,不再有 `is_multimodal` 分支。
|
||||
- **收益**:VDB 与 Embedder 职责清晰;后续接入 ColBERT / SPLADE / 多向量 Embedding 时无需修改 VDB。
|
||||
- **成本与风险**:约 **2 人日**。
|
||||
- **优先级**:**P2**(依赖建议 1 完成)。

```
|

|
||||
### 2.2 PoC-2:Embedder + Redis 缓存装饰器(建议 1 + 4)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/cache/embed_cache.py
|
||||
import json, xxhash, numpy as np
|
||||
from functools import wraps
|
||||
|
||||
def cached_embedder(redis_client, ttl: int = 24 * 3600):
|
||||
def decorator(func):
|
||||
@wraps(func)
|
||||
def wrapper(self, texts, *args, **kwargs):
|
||||
if isinstance(texts, str):
|
||||
texts = [texts]
|
||||
keys = [_key(self.model_name, t) for t in texts]
|
||||
cached = redis_client.mget(keys)
|
||||
results, miss_idx, miss_texts = [None]*len(texts), [], []
|
||||
for i, b in enumerate(cached):
|
||||
if b: results[i] = np.array(json.loads(b))
|
||||
else: miss_idx.append(i); miss_texts.append(texts[i])
|
||||
if miss_texts:
|
||||
fresh = func(self, miss_texts, *args, **kwargs) # ndarray, n_tokens
|
||||
vecs = fresh[0] if isinstance(fresh, tuple) else fresh
|
||||
pipe = redis_client.pipeline()
|
||||
for j, idx in enumerate(miss_idx):
|
||||
results[idx] = vecs[j]
|
||||
pipe.setex(keys[idx], ttl, json.dumps(vecs[j].tolist()))
|
||||
pipe.execute()
|
||||
return np.array(results), 0 # tokens cached as 0; metric layer补
|
||||
return wrapper
|
||||
return decorator
|
||||
|
||||
def _key(model: str, text: str) -> str:
|
||||
h = xxhash.xxh64(); h.update(f"{model}\0{text}".encode()); return f"emb:{h.hexdigest()}"
|
||||
```
|
||||
|
||||
使用方式:
|
||||
|
||||
```python
|
||||
class OpenAIEmbed(Base):
|
||||
@cached_embedder(redis_client) # 一行注解开启缓存
|
||||
def encode(self, texts: list): ...
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 3. 改造路线图
|
||||
|
||||
> 实施前提:先用 1 周时间立两个 baseline —— (a) 当前端到端 P50/P95(即使靠手工脚本采);(b) 单测覆盖率(pytest --cov)。所有改造完成后用同一 baseline 比对,验证收益。
|
||||
|
||||
### 3.1 短期(Sprint 0–1,1-2 周内交付)
|
||||
|
||||
> 目标:止血 + 解锁后续重构的前置条件。

|
||||
|
||||
### 3.2 中期(Sprint 2–4,1-2 月内交付)
|
||||
|
||||
> 目标:完成核心抽象层重构,引入可观测性。
|
||||
|

|
||||
| 11 | Embedder 与 Rerank 批量化 + 异步并发改造 | #9 | 3d | 性能 benchmark 对比报告 |
|
||||
|
||||
**中期里程碑(Sprint 4 末)**:

|
||||
- ✅ Grafana 实时面板:P50/P95/Token 用量/缓存命中率;
|
||||
- ✅ 单测覆盖率 RAG 模块从 ~5% 提升到 ≥35%;
|
||||
- ✅ 端到端 P95 较 baseline 下降 30%+。
|
||||
|
||||
### 3.3 长期(Sprint 5–8,3-6 月内交付)
|
||||
|
||||
> 目标:可插拔架构、生产级稳定性、为 [S3-T2] 列出的多模态 / 混合搜索增强 / KG 演化做铺垫。
|
||||
|
||||
| # | 工作项 | 关联建议 | 工作量 | 交付物 |
|
||||
|---|---|---|---|---|
|
||||
| 12 | 多模态分支从 VDB 抽离到 Embedder | #11 | 2d | VDB 接口收敛 |
|
||||
| 13 | 引入第二个 VDB 实现(如 Milvus),验证 `BaseVector` 可插拔 | #2 | 8d | `MilvusVector` + 一致性测试套件 |
|
||||
| 14 | LLM Provider 也改 Plugin Registry(消除 `chat_model.py` 11 个子类的 if 切换) | #5 | 5d | LLM 层与 Embedding 层架构对齐 |
|
||||
| 15 | 完整的 `Pipeline = Retriever \| Reranker \| Generator` DSL,配置驱动 | #2 | 10d | YAML 描述场景 → 运行时拼装 |
|
||||
| 16 | A/B 实验框架:基于 OTel metric,把 recall@k / answer_score 接入实验对比 | #6 | 5d | 实验平台对接文档 |
|
||||
| 17 | LLM 失败模型降级链(fallback to 备用 provider) | #2 + 现有 Base 增强 | 3d | `FallbackGenerator` 实现 |
|
||||
| 18 | 安全 / Secret 管理:从 `pydantic.SecretStr` 升级到 Vault / Secrets Manager 集成 | #7 | 5d | 密钥不进 .env 文件 |
|
||||
|
||||
**长期里程碑(Sprint 8 末)**:
|
||||
- ✅ 可插拔 VDB(一行配置切换 ES → Milvus);
|
||||
- ✅ Pipeline DSL 上线,新增"GraphRAG-Then-Vector-Then-Rerank"等组合无需改代码;
|
||||
- ✅ 全链路 Trace + 指标 + A/B 框架就绪;
|
||||
- ✅ 为 [S3-T2] 中"多模态检索 / SPLADE / ColBERT 路由 / KG 演化 / 反馈闭环"等扩展提供清晰的接口注入点。

## 4. 风险与依赖统一汇总
|
||||
|
||||
| 风险类别 | 描述 | 缓解方案 |
|
||||
|---|---|---|
|
||||
| **回归风险(高)** | `Embedder` 协议迁移可能改变返回类型(`np.ndarray` vs `list[list[float]]`) | 6 个月兼容期,旧接口保留并打 `DeprecationWarning`;CI 加契约测试 |
|
||||
| **回归风险(中)** | `KnowledgeRetrievalNode` 接口改造,影响 workflow 已部署应用 | 引入 `node_v2.py`,灰度切换;保留 `node.py` 至少一个 release |
|
||||
| **依赖风险** | OpenTelemetry 接入需 collector / Tempo / Loki 等基础设施 | 短期可先只导出到 stdout exporter,基础设施分阶段建设 |
|
||||
| **协作依赖** | 与 [@Python 开发工程师](mention://agent/f4d1c89f-0c71-4af3-bf72-d34f7ed115cf) 一起验证 PoC 与迁移可行性 | Sprint 0 启动前先 1 次架构对齐会 |
|
||||
| **运营依赖** | 配置治理(建议 #7)落地后,运维需更新部署脚本与文档 | 切换前 2 周通知;提供变量映射表(旧 → 新) |

# MemoryBear RAG · 后续迭代功能新增方式建议(S3-T2)
|
||||
|
||||
> 上游:[WS-11] 总规划、[S1-T2 全链路架构]、[S1-T3 源码盘点]、Sprint-2 各环节深度文档、[S3-T1 架构改造建议]
|
||||
> 输出形态:能力地图 + 6 个重点扩展方向 + 2 条 Quick PoC + 优先级矩阵 + 落地路线图
|
||||
> 设计原则:所有方向 **必须** 复用 [S3-T1] 提议的统一抽象(`Retriever / Reranker / Generator / Embedder / Loader / Chunker`),避免出现新功能 = 新一团耦合。
|
||||
|
||||
---
|
||||
|
||||
## 0. 现状速览与设计基线
|
||||
|
||||
### 0.1 一图看清"已有 / 可上 / 愿景"
|
||||
|
||||
详见附件 `capability-map.mmd`(Mermaid 格式)。三色对应:
|
||||
- 🟢 **已有**:Sprint-2 文档已覆盖、源码可证、生产可用。
|
||||
- 🟡 **近期可上**:1–2 个 Sprint 内可落地,依赖最少。
|
||||
- 🟣 **中长期愿景**:3–6 个月,存在跨团队/外部依赖。
|
||||
|
||||
### 0.2 关键源码事实(用于支撑后续方案)
|
||||
|
||||
| 事实 | 源码定位 | 对扩展的影响 |
|
||||
|------|---------|-------------|
|
||||
| 多模态目前 **走文本通道** | `rag/app/picture.py:54` 调 `vision_model.describe`;`rag/app/audio.py:29` 调 `seq2txt_mdl.transcription`;`naive.py` 走 video → VLM → 文本 | 跨模态语义损失大;扩展为"原生跨模态向量"是方向 D1 |
|
||||
| `MatchSparseExpr` 已声明但未接入 | `rag/utils/doc_store_conn.py:75` 与 `vdb/field.py:11(SPARSE_VECTOR)` 都已存在;`grep -r SparseVector` 仅 1 处定义、0 处调用 | SPLADE 接入是脚手架级改造,不是从零开始(D2) |
|
||||
| 混合检索权重写死 `0.05,0.95` | `rag/nlp/search.py:439` 的 `FusionExpr("weighted_sum", topk, {"weights": "0.05,0.95"})` | 语义路由 / 自适应权重的注入点天然存在(D2) |
|
||||
| GraphRAG 是"一次构建"模型 | `tasks.py` 的 `build_graphrag_for_document` Celery 链;图存于 ES `knowledge_graph_kwd` 字段 | 增量演化、时间维度、Neo4j 双引擎需要在 Celery 链上加 hook(D3) |
|
||||
| 对话记忆与 RAG **不互通** | `core/memory/` 自成一套(Ebbinghaus、ACT-R、Neo4j、langgraph 读图);`workflow/nodes/knowledge/node.py` 完全不引用 `core/memory` | 对话记忆 ↔ 检索的协同是最大产品差异化机会(D4) |
|
||||
| 评估只在 README 体现 | 仓内无 `eval/`、`ragas`、`F1` 类计算代码 | 反馈闭环要从 0 搭,但与 [S3-T1] 提议的"可观测性"天然合并(D5) |
|
||||
| Reranker 只能推理不能学 | `core/models/rerank.py:11` 包装 langchain `BaseDocumentCompressor`,仅做远程调用 | 自训练 Cross-Encoder 是一条独立、可量化收益的小路径(D5) |
|
||||
| 检索模式硬编码在 enum | `RetrieveType.{PARTICIPLE, SEMANTIC, HYBRID, Graph}` 在 `schemas/chunk_schema.py` | 引入"语义路由"需要把 enum 改成 strategy 模式(D6) |
|
||||
|
||||
### 0.3 与 [S3-T1] 接口抽象的联动约定
|
||||
|
||||
[S3-T1] 提议把当前散落的检索/排序/生成代码抽象为协议(参考 LangChain Runnable)。本路线图的所有"接口改造点"都引用以下统一协议(命名以 [S3-T1] 终稿为准,本稿先行登记):
|
||||
|
||||
```python
|
||||
# rag/protocols.py([S3-T1] 提议)
|
||||
class Retriever(Protocol):
|
||||
async def retrieve(self, query: Query, ctx: RetrievalContext) -> list[ScoredChunk]: ...
|
||||
|
||||
class Reranker(Protocol):
|
||||
async def rerank(self, query: Query, chunks: list[ScoredChunk], ctx: RerankContext) -> list[ScoredChunk]: ...
|
||||
|
||||
class Embedder(Protocol):
|
||||
def encode(self, items: list[Embeddable]) -> EmbeddingResult: ... # Embeddable = str | Image | Audio | ...
|
||||
|
||||
class Generator(Protocol):
|
||||
async def generate(self, system: str, history: list[Msg], ctx: GenContext) -> GenResult: ...
|
||||
```
|
||||
|
||||
> **原则**:本文档每条扩展方向都以"新增/扩展某 Protocol 实现 + 注册到工厂"为接入方式,**不**改动调用方代码。这样可以保持 N 个扩展方向 **并行落地** 而不互相阻塞。
|
||||
|
||||
---
|
||||
|
||||
## 1. 重点扩展方向
|
||||
|
||||
> 共 6 个方向。第 5、6 个为前述 5 个外的延伸(自适应路由),但和"评估闭环 / 混合搜索 / 对话记忆"高度互补,建议合并审阅。
|
||||
|
||||
### D1. 多模态检索(原生跨模态向量空间)
|
||||
|
||||
#### 1.1 触发场景
|
||||
- 客户问:"去年那张含 'Q3 GMV' 的 PPT 切片在哪?" — 当前只能命中 OCR 抽出的文字,**布局/图表整体语义** 丢失。
|
||||
- 视频会议纪要库:用户描述"那段讲到老王说'下季度先稳住毛利'的会议",纯 ASR 文本无法绑定 **说话人 + 时间 + 屏幕共享上下文**。
|
||||
- 设备图谱:硬件型号识图("这块板子是哪一版"),目前只能让 VLM 描述后再走文本检索,VLM 描述不稳定。
|
||||
|
||||
#### 1.2 技术方案
|
||||
分三层逐步推进:
|
||||
|
||||
| 层级 | 方案 | 依赖组件 |
|
||||
|------|------|---------|
|
||||
| L1(基线增强) | **关键帧抽样 + VLM 多次 describe**:视频每 N 秒抽帧,每帧 VLM 描述独立 chunk,附 `frame_ts` 元数据;图片在 OCR + describe 之外再加 **结构化 VQA**("图中有什么图表/品牌/人脸?") | 现有 `cv_model.py`、`sequence2txt_model.py` 即可;新增 `rag/app/video.py` |
|
||||
| L2(跨模态检索) | 引入 **CLIP / BGE-VL / Jina-Clip-v2** 作为 `MultimodalEmbedder` Protocol 实现:图片直接编码为向量,文本 query 编码到 **同一向量空间**;ES 索引增加 `vec_image_q_<dim>_vec` 列 | 新依赖 `transformers` / `sentence-transformers` 或托管 API;GPU 资源 |
|
||||
| L3(视听统一) | **Whisper + speaker diarization**(pyannote)替换当前一段式 ASR;视频 chunk 同时持有 `text_vec`(ASR 文本)+ `image_vec`(关键帧) + `audio_vec`(可选,用 CLAP) | `pyannote.audio`、`open_clip`;额外存储约 +30% |
|
||||
|
||||
#### 1.3 接口改造点(基于 S3-T1)
|
||||
- 扩展 `Embedder.encode(items: list[Embeddable])`:`Embeddable = str | PILImage | AudioBytes | VideoFrame`,返回 `EmbeddingResult(vector, modality, dim)`。
|
||||
- 新增 `MultimodalRetriever(Retriever)` 实现:内部根据 query 的 `modality_hint`(文本默认)选择走 `text_vec` 还是 `image_vec` 列。
|
||||
- VDB 层 schema 演进(`rag/vdb/elasticsearch/elasticsearch_vector.py:653+` 的 mapping 创建):把"硬编码单 vector 列"改造为"按 modality 多列动态注册";落地依赖 [S3-T1] 提到的 mapping 模板化改造。
|
||||
- `app/picture.py` / `app/audio.py` 的 `chunk()` 函数输出 dict 中新增 `image_b64` / `audio_b64` 字段,供 Embedder 后续无损取用(避免 PIL 对象在 Celery pickle 边界丢失)。
|
||||
|
||||
#### 1.4 工作量估计
|
||||
- L1 基线:**1.5 人周**(2 个 PR:视频抽帧;结构化 VQA prompt)
|
||||
- L2 跨模态:**3 人周**(含 Embedder 抽象、ES schema 迁移、回归测试)
|
||||
- L3 视听统一:**4 人周**(含 GPU 容器、speaker diarization 集成)
|
||||
- 合计:**~1.5 + 3 + 4 ≈ 8.5 人周**(可分阶段产出)
|
||||
|
||||
#### 1.5 风险与依赖
|
||||
- ⚠️ **存储膨胀**:image_vec(768d float32)单图 3KB,1M 图 ≈ 3GB;ES dense_vector 启用 `int8_hnsw` 量化可减 75%。
|
||||
- ⚠️ **VLM 描述漂移**:同一图不同时间不同模型版本,描述差异大;需要 caption 缓存(key = `sha256(image)+model_version`)。
|
||||
- ⛓️ **强依赖**:[S3-T1] mapping 模板化改造完成后再做 L2,否则 schema 演进会成阻塞点。
|
||||
- ⛓️ **GPU 依赖**:L2/L3 在自建 GPU 节点或托管 API 二选一;建议先走托管(Jina-Clip API)跑通端到端,再评估自托管。
|
||||
|
||||
---
|
||||
|
||||
### D2. 混合搜索增强(Sparse + Dense + Late-Interaction + 自适应路由)
|
||||
|
||||
#### 2.1 触发场景
|
||||
- "工号 E12345 的 OKR" — 长尾标识符,BM25 强、稠密向量弱,**当前 0.05/0.95 权重几乎让 BM25 失语**。
|
||||
- "怎么做用户分层运营?" — 概念性问题,dense 强、BM25 弱。
|
||||
- "GraphRAG 和 LightRAG 的区别" — 需要 ColBERT 这类 token 级精排,单向量混淆术语。
|
||||
|
||||
#### 2.2 技术方案
|
||||
|
||||
| 子方向 | 方案 | 价值 |
|
||||
|-------|------|------|
|
||||
| **SPLADE 学习稀疏** | 用 `naver/splade-cocondenser-ensembledistil` 或国产 BGE-M3 sparse 输出,每个文档生成稀疏向量(含 token expansion);接入 `MatchSparseExpr`(**已存在但未启用**) | 把 BM25 的"词形匹配"升级为"学习权重 + 自动同义扩展" |
|
||||
| **ColBERT 后期交互** | 文档级向量改为 token 级(一篇文档 N 个 token vector,N≈chunk_token_num/3);retrieval 时用 MaxSim;可仅在 reranker 阶段使用 | 在精确匹配上比 cross-encoder 快 5–10×,质量接近 |
|
||||
| **语义路由 / 自适应权重** | 先用一个轻 LLM(或 query classifier)判定 query 类型(lookup / concept / list / multi-hop / temporal),路由到 `{BM25权重, vector权重, 是否使用 Graph, 是否使用 Rerank}` | 替代当前写死的 `0.05/0.95`;可灰度(query 哈希 % 100 < 5 上新策略) |
|
||||
| **多向量召回融合** | 同 chunk 同时索引 BM25、dense、sparse 三类,retrieval 后用 RRF (Reciprocal Rank Fusion) 融合 | 工程上 RRF 不需训练,落地最快 |
|
||||
|
||||
#### 2.3 接口改造点
|
||||
- 新增 `SparseEmbedder(Embedder)` 实现:返回 `SparseVector(indices, values)`;ES mapping 增加 `q_sparse_<vocab>_vec` 字段,使用 `rank_features`/`sparse_vector` 类型(ES ≥ 8.11)。
|
||||
- 在 `rag/nlp/search.py:Dealer.search()`(第 387 行起)把 `FusionExpr` 的硬编码权重改为 `ctx.fusion_weights`,由 `Retriever` 实现的 `ctx` 参数注入。
|
||||
- 新增 `RouterRetriever(Retriever)`:组合多个底层 retriever(DenseRetriever / SparseRetriever / GraphRetriever),按 router 决策选择 / 融合。
|
||||
- ColBERT 仅在 Reranker 层接入:新增 `ColBERTReranker(Reranker)` 实现;接 `Reranker` 协议,**完全不影响**调用方。
|
||||
|
||||
#### 2.4 工作量估计
|
||||
- RRF 多路融合(**Quick PoC,见 §2**):**0.5 人周**
|
||||
- SPLADE 接入:**2 人周**(含 ES mapping、批量重建索引)
|
||||
- 语义路由:**2.5 人周**(含 router 训练数据采集、灰度框架)
|
||||
- ColBERT Reranker:**3 人周**(GPU 部署 + 蒸馏小型化)
|
||||
- 合计:**~8 人周**
|
||||
|
||||
#### 2.5 风险与依赖
|
||||
- ⚠️ **重建索引成本**:现网 KB 数量 × chunk 数 × 维度,估算总耗时;需要提供"灰度索引切换"工具(详见 §6 路线图 P0)。
|
||||
- ⚠️ **路由器误判**:错路由比无路由更糟;必须配 fallback(路由失败回退到当前默认 0.05/0.95)。
|
||||
- ⛓️ **依赖 [S3-T1]** 的 `Retriever` Protocol 落地后才能优雅接入路由器;否则会污染 `Dealer` 类。
|
||||
|
||||
---
|
||||
|
||||
### D3. 知识图谱增强(基于 [S2-T4] GraphRAG 的延伸)
|
||||
|
||||
#### 3.1 触发场景
|
||||
- 法务/合规库每月新增 200+ 条法规:当前必须 **重建整个图**,CI 跑 1 小时;用户要求"增量入库 + 增量图更新"。
|
||||
- 报错排查:"TS_001 错误码可能由哪些组件触发?" — 需要从 **错误码** 节点 N-hop 走到 **组件** 节点;当前 KGSearch 走的是文本相似度匹配实体,**不是路径推理**。
|
||||
- 团队要求"为什么是这个答案" — 需要把推理路径(A→关系1→B→关系2→C)作为 citation 一同返回,提供 **可解释性**。
|
||||
|
||||
#### 3.2 技术方案
|
||||
|
||||
| 子方向 | 方案 | 现状 → 目标 |
|
||||
|-------|------|------------|
|
||||
| **增量图演化** | 在 `tasks.py:build_graphrag_for_document` 链上插入 `GraphMerge` 阶段:新文档抽出的子图与全图做 **节点对齐 + 关系合并 + 冲突标记**;保留 `version_int` 字段记录每条边的"加入/失效"版本号 | 一次构建 → 增量更新 + 时间溯源 |
|
||||
| **路径解释性** | KGSearch.retrieval() 输出新增 `evidence_path: list[Edge]`;在 prompt 组装时把路径作为引用源;前端渲染"由 X→Y→Z 推断" | 黑盒答案 → 带溯源链路 |
|
||||
| **Neo4j 双引擎** | 当前图存在 ES 的 chunk 表里(`knowledge_graph_kwd` 字段),不能利用图算法;引入 Neo4j 作为 **算法引擎**(PageRank 已在 ES 里跑过,但 Cypher 跑社区检测、最短路径远更便利);ES 仍负责文本召回,Neo4j 负责图算法。README 已声明 Neo4j 是组件,**只是 RAG 层没用** | 单引擎 → 检索 ES + 图算法 Neo4j 混合 |
|
||||
| **温度敏感的图衰减** | 复用 `core/memory/forgetting_engine` 的 Ebbinghaus 实现到图边权重:长期未被命中的实体/关系权重衰减;与 D4 共享一套衰减逻辑 | 静态图 → 动态、有"记忆"的图 |
|
||||
| **自动本体演化** | 借鉴 `core/memory/ontology_services/General_purpose_entity.ttl`,定期用 LLM 检查"这批新加的实体类型是否应该归并到已有类型?" | 类型膨胀 → 受控演化 |
|
||||
|
||||
#### 3.3 接口改造点
|
||||
- 新增 `GraphRetriever(Retriever)` 实现,包装现有 `KGSearch`;输出 `ScoredChunk.metadata` 增加 `evidence_path`(`list[(from_entity, relation, to_entity, confidence)]`)。
|
||||
- 新增 `GraphStore` 抽象层:`add_subgraph / merge / query_path / pagerank / community_detect`;实现两个:`ESGraphStore`(保留现状)、`Neo4jGraphStore`(新增)。`graphrag/general/index.py` 现在直接操作 `nx.Graph`,全部替换为 `GraphStore` 调用。
|
||||
- 在 `tasks.py` 的 Celery 链增加 `graph_merge_task`:依赖 `build_graphrag_for_document`,处理增量合并;需要分布式锁(已有 `redis_lock.py` 可用)。
|
||||
- Prompt 层(`prompts/generator.py`)新增 `evidence_aware_citation_prompt`:把 `evidence_path` 作为额外上下文注入。
|
||||
|
||||
#### 3.4 工作量估计
|
||||
- 增量图演化(最小可用):**3 人周**(最复杂的是合并冲突的实体消歧)
|
||||
- 路径解释性:**2 人周**
|
||||
- Neo4j 双引擎:**3 人周**(含 Cypher 工具集、Neo4j 数据迁移脚本)
|
||||
- 图衰减 + 本体演化:**2 人周**(与 D4 共享代码)
|
||||
- 合计:**~10 人周**
|
||||
|
||||
#### 3.5 风险与依赖
|
||||
- ⚠️ **实体消歧难度**:跨文档同名异义("苹果"=公司 / 水果);建议用现有 `entity_resolution.py` 改造,但需要补全单元测试。
|
||||
- ⚠️ **Neo4j 运维成本**:用户已在 README 声明依赖 Neo4j,但当前 RAG 层零调用;引入意味着同时管理两个图的一致性。建议把 Neo4j 定位为"算法只读 / 异步同步",避免双写一致性。
|
||||
- ⛓️ **依赖 [S3-T1]** 把 `GraphStore` 与 `Retriever` 协议落实,否则会跨层塌方。
|
||||
|
||||
---
|
||||
|
||||
### D4. 对话记忆 ↔ RAG 协同(短期 / 长期 / 检索召回三段桥接)
|
||||
|
||||
> **MemoryBear 的核心特色**。当前最大产品差异化机会就在这里——`core/memory/` 与 `core/rag/` 是 **两条独立链路**,没有联动。
|
||||
|
||||
#### 4.1 触发场景
|
||||
- 用户在第 3 轮说"我对海鲜过敏",第 7 轮问"今晚吃什么?" — 当前 RAG 层无任何记忆能力,每次只看当轮 query。
|
||||
- 多 Agent 协作:售前 Agent 收集到客户预算,售后 Agent 重新询问 — 跨 Agent 记忆需要从 `core/memory` 读出 + 注入 RAG 检索 query 重写。
|
||||
- 长对话上下文压缩:第 50 轮时,前 40 轮对话需要 **被遗忘但保留要点**,要点变成"用户档案 chunk"加入 KB。
|
||||
|
||||
#### 4.2 短期 / 长期 / 检索召回的边界(产品决策)
|
||||
|
||||
| 维度 | 短期记忆(Working Memory) | 长期记忆(Episodic / Semantic) | 检索召回(KB) |
|
||||
|------|---------------------------|--------------------------------|---------------|
|
||||
| 存储位置 | Redis,单 session 8KB cap | Neo4j + ES(`core/memory`) | ES(`core/rag`) |
|
||||
| 生命周期 | session(< 24h) | 永久(按 forgetting curve 衰减) | 永久(人工治理) |
|
||||
| 写入触发 | 每轮 user/assistant message | reflection_engine 周期性提炼 | 文档入库流水线 |
|
||||
| 召回时机 | 始终注入 prompt | LLM 重写 query 时 + 主动检索 | RetrievalNode 命中 |
|
||||
| 数据契约 | `list[Msg]` | `MemoryItem(content, strength, type, ts)` | `DocumentChunk` |
|
||||
| 可信度 | 高(用户原话) | 中(LLM 提炼) | 高(人工审核) |
|
||||
|
||||
> **决策原则**:"用户原话进短期,提炼事实进长期,世界知识进 KB。" 三者不能互相替代。
|
||||
|
||||
#### 4.3 技术方案
|
||||
- **MemoryAugmentedRetriever**:在 `RouterRetriever` 之外再包一层,retrieve 前用 `core/memory.read_services` 拿到当前 user 的 top-K 长期记忆条目,**改写 query**("今晚吃什么?" + 长期记忆"对海鲜过敏" → "今晚吃什么?避免海鲜")。
|
||||
- **Memory Citation**:检索结果与长期记忆条目并入同一 `chunks` 列表,prompt 模板区分两者来源("用户提及" vs "知识库"),避免幻觉混淆。
|
||||
- **反向写入**:每轮对话产出后,让 `core/memory.write_router` 决定 是否需要把"新事实"写入长期记忆;这一步 **复用** `core/memory.agent.langgraph_graph.write_graph`(已存在)。
|
||||
- **遗忘对齐**:把 `core/memory/forgetting_engine` 的 ACT-R 计算复用到 KB chunk 上(D3 已提);让"很少被命中的过期 KB chunk"自动沉睡,反向触发治理团队复审。
|
||||
|
||||
#### 4.4 接口改造点
|
||||
- 在 `workflow/nodes/knowledge/node.py` 的 `KnowledgeRetrievalNode.execute()` 中注入 `MemoryService`:当节点配置里 `enable_memory=true` 时,先调 `memory_service.recall(user_id, query)` 拿记忆,再传给 `Retriever.retrieve(query, ctx={memory: ...})`。
|
||||
- 新增 `MemoryAwareRetriever(Retriever)` 实现,包装任一底层 Retriever。
|
||||
- Workflow Node 配置 `KnowledgeRetrievalNodeConfig` 增加 `memory_strategy: Literal["off", "context_only", "rewrite_query", "merge_chunks"]`。
|
||||
- Prompt 模板新增 `<MEMORY>` 段落。
|
||||
|
||||
#### 4.5 工作量估计
|
||||
- 单向(memory → retrieval):**3 人周**
|
||||
- 双向(retrieval 结果反写 memory):**2 人周**(大部分代码已在 `core/memory` 存在)
|
||||
- 遗忘对齐 + 治理触发:**2 人周**(与 D3 共享)
|
||||
- 合计:**~7 人周**
|
||||
|
||||
#### 4.6 风险与依赖
|
||||
- ⚠️ **隐私边界**:长期记忆是 **per-user**,KB 是 **per-tenant**;混淆会导致跨用户泄露。设计时必须 user_id 级强隔离,code review 重点。
|
||||
- ⚠️ **Prompt 长度膨胀**:记忆 + KB 双源;如果未做摘要,长对话场景 token 成本翻倍;必须配合记忆摘要(已有 `summary4memory.md`)。
|
||||
- ⛓️ **依赖 [S3-T1]** 的 `Retriever / Reranker` 协议;强依赖 [S2-T6] 的 E2E 时序图明确两条链路的衔接点。
|
||||
|
||||
---
|
||||
|
||||
### D5. 评估与反馈闭环(用户反馈 → Reranker 微调)
|
||||
|
||||
#### 5.1 触发场景
|
||||
- 答案错了 / 引用不对,用户点👎 — 当前数据 **进了日志,没人消费**。
|
||||
- 同一 query 在不同时段表现波动 → 需要离线 A/B 评估。
|
||||
- 业务方问"再加一个 KB 之后效果到底变好还是变差?" — 没有可量化的回归指标。
|
||||
- README 给的 F1/BLEU/J 在论文中实现过,**但仓内没有这套代码**,每次评估靠手工。
|
||||
|
||||
#### 5.2 技术方案(双轨:评估在线化 + 反馈学习)
|
||||
|
||||
##### 5.2.1 评估轨:离线 / 在线 / CI 三层
|
||||
|
||||
| 层级 | 内容 | 工具 |
|
||||
|------|------|------|
|
||||
| **离线评估集** | 每 KB 维护一个 `eval_cases.jsonl`:`{query, ideal_chunks, ideal_answer, hard_negatives}`;增量构建(每周从用户问句 + 答疑团队补充) | DSL + Excel 导入工具 |
|
||||
| **在线指标** | `Hit@K / MRR / nDCG / Citation Coverage / Hallucination Rate / Latency P50/P95`;通过 OpenTelemetry 埋点写入 Prometheus | OTel + Prometheus + Grafana |
|
||||
| **CI 评估** | 每个 PR 跑核心 KB 的回归集;指标低于 baseline n% 时阻塞合并 | RAGAS(开源)+ 自研判分 prompt |
|
||||
|
||||
##### 5.2.2 反馈学习轨:从👍/👎到 Reranker 微调
|
||||
|
||||
```
|
||||
用户反馈(👍/👎/edit)
|
||||
↓ event log
|
||||
事件清洗(同一 query 多个 chunk 评分)
|
||||
↓
|
||||
形成 (query, positive_chunk, negative_chunk) 三元组
|
||||
↓

```
|
||||
|
||||
#### 5.3 接口改造点
|
||||
- 新增 `EvaluationProtocol`:`{evaluate(query, retrieved, generated, ground_truth) -> Metrics}`;在 OpenTelemetry trace 末尾自动落 Prometheus。
|
||||
- `RedBearRerank` 改造:接入 `LocalCrossEncoderRerank(Reranker)` 子类,加载本地 ONNX/TorchScript 模型;可与 Jina/DashScope 并存于工厂。
|
||||
- 反馈采集:复用 `core/memory` 的事件总线(如有)或新建 `feedback_event` 表;前端组件加 thumbs;citation 点击行为也作为隐式反馈。
|
||||
- 训练 pipeline 独立仓 / 独立服务;产物(ONNX)通过模型注册表(用现有 `ModelConfig` 表扩展即可)滚动上线。
|
||||
|
||||
#### 5.4 工作量估计
|
||||
- 评估指标埋点 + Grafana 看板:**1.5 人周**
|
||||
- 离线评估集 + RAGAS CI 集成:**2 人周**
|
||||
- 反馈采集 + 三元组清洗:**1 人周**
|
||||
- Cross-Encoder 蒸馏训练 pipeline:**3 人周**(含数据扩充、训练脚本、产出 ONNX)
|
||||
- 合计:**~7.5 人周**
|
||||
|
||||
#### 5.5 风险与依赖
|
||||
- ⚠️ **冷启动**:刚上线时反馈数据 < 1k 不足以训练;必须先用大模型 LLM-as-Judge 合成训练数据(现成 prompt 在 `prompts/generator.py` 可借鉴)。
|
||||
- ⚠️ **反馈污染**:恶意 / 误点;需要置信度过滤(同一 user 短时多次相反反馈丢弃)。
|
||||
- ⛓️ **依赖 [S3-T1]** 的可观测性方案,否则数据采不到。
|
||||
- ⛓️ **依赖 D2 的语义路由**,否则没有"权重可调"的注入点。
|
||||
|
||||

|
||||
|
||||
### D6. 自适应检索路由(Adaptive Retrieval Routing)
|
||||
|
||||
> 这是 D2 中"语义路由"的工程化升级版,独立列出是因为它会**统一**所有检索能力(dense / sparse / graph / memory / web),是 RAG 系统的中央调度器。
|
||||
|
||||
#### 6.1 触发场景
|
||||
- 同一用户在同一 session 内:第 1 个问题需要走 KB,第 2 个问题需要走 Web 搜索("今天的新闻"),第 3 个问题需要 Graph 推理 — 当前必须用户手动切模式。
|
||||
- "你刚才推荐的方案做不了"(指代消解)→ 需要先走对话记忆,再决定是否检索;当前都是无脑全检索。
|
||||
|
||||
#### 6.2 技术方案
|
||||
|
||||
| 决策类型 | 输入 | 输出 |
|
||||
|---------|------|------|
|
||||
| 是否需要检索 | query + 短期记忆 | `bool need_retrieval` |
|
||||
| 检索来源 | query 类型 | `[KB_id, Graph_flag, Web_flag, Memory_flag]` |
|
||||
| 检索策略 | query 类型 + 用户场景 | `(retriever_name, top_k, fusion_weights, rerank_id)` |
|
||||
| 兜底 | 第一次检索结果差 | 触发 query rewriting + 二次检索 |
|
||||
|
||||
实现:
|
||||
- 路由器 = 小型 LLM(如 1.5B–3B)+ rule-based fallback;输出结构化 JSON。
|
||||
- 训练数据来源:D5 的反馈数据 + 标注团队人工标 1k 条。
|
||||
- 推理用 vllm 或 SGLang 自托管,P95 延迟控制在 50ms。
|
||||
|
||||
#### 6.3 接口改造点
|
||||
- 把 `RetrieveType` enum 改造成 strategy(与 D2 共享的 `RouterRetriever`);workflow 层调用方不再选模式,而是传入 query。
|
||||
- 新增 `RoutingPolicy` 配置实体:可被工作空间管理员通过 UI 编辑(默认策略 + 灰度策略)。
|
||||
- 与 D5 形成闭环:评估指标决定路由器升级时机。
|
||||
|
||||
#### 6.4 工作量估计
|
||||
- 规则+LLM 路由器最小可用:**2 人周**
|
||||
- 完整训练 / 灰度 / 配置 UI:**5 人周**
|
||||
- 合计:**~7 人周**
|
||||
|
||||
#### 6.5 风险与依赖
|
||||
- ⚠️ **路由器变成单点**:必须有 fallback 到当前默认策略。
|
||||
- ⛓️ **强依赖 D2 + D5**;不建议独立做。
|
||||

|
||||
|
||||
## 2. Quick PoC 路径(≤ 1 周可见效果)
|
||||
|
||||
### PoC-A:RRF 多路融合检索(属 D2)
|
||||
|
||||
**目标**:现网 KB 在不重建索引、不改 schema 的前提下,加入 BM25 + dense 各自独立 top-50 → RRF 融合 → 同一接口返回。1 周内拿到 A/B 数据。
|
||||
|
||||
**改动范围**(最小集):
|
||||
- `rag/nlp/search.py:Dealer.search()` 拆为两步:先单独跑 BM25(`emb_mdl=None`),再单独跑 dense(无 BM25),合并时用 RRF。
|
||||
- 增加 feature flag `RETRIEVAL_FUSION_MODE = {"weighted", "rrf"}`,默认 weighted(不影响现网)。
|
||||
|
||||
**预期收益**:在长尾 lookup query 上 Hit@10 +5–10pp(参考社区数据)。无负向风险,因为 weighted 路径保留。
|
||||
|
||||
**PoC 代码草案**(伪代码,约 30 行;正式实现需走完整 PR + 评估):
|
||||
|
||||
```python
|
||||
# rag/retrieval/rrf.py(新增)
|
||||
def rrf_merge(rankings: list[list[ScoredChunk]], k: int = 60, top_k: int = 20) -> list[ScoredChunk]:
|
||||
"""Reciprocal Rank Fusion: score = Σ 1/(k + rank_i)。
|
||||
rankings: 多个独立排序结果,每个内部按相关度降序。
|
||||
"""
|
||||
score_map: dict[str, float] = {}
|
||||
chunk_map: dict[str, ScoredChunk] = {}
|
||||
for ranking in rankings:
|
||||
for rank, chunk in enumerate(ranking, start=1):
|
||||
cid = chunk.metadata["doc_id"]
|
||||
score_map[cid] = score_map.get(cid, 0.0) + 1.0 / (k + rank)
|
||||
chunk_map[cid] = chunk # 保留首次见到的对象
|
||||
merged = sorted(chunk_map.values(),
|
||||
key=lambda c: score_map[c.metadata["doc_id"]],
|
||||
reverse=True)
|
||||
for c in merged:
|
||||
c.metadata["score_rrf"] = score_map[c.metadata["doc_id"]]
|
||||
return merged[:top_k]
|
||||
|
||||
|
||||
# 调用侧(rag/nlp/search.py:Dealer.search 增量改造)
|
||||
if os.getenv("RETRIEVAL_FUSION_MODE", "weighted") == "rrf":
|
||||
bm25_hits = self._search_bm25_only(req, ...)
|
||||
dense_hits = self._search_dense_only(req, ...)
|
||||
return rrf_merge([bm25_hits, dense_hits], k=60, top_k=req.get("topk", 20))
|
||||
# else: 走现有 weighted 路径
|
||||
```
|
||||
|
||||
### PoC-B:Memory-Augmented Query Rewrite(属 D4)
|
||||
|
||||
**目标**:把 `core/memory.read_services` 已有的"长期记忆召回"接到 `KnowledgeRetrievalNode` 之前,做 query 改写。1 周内对 1 个内部 demo 应用上线。
|
||||
|
||||
**改动范围**:
|
||||
- `KnowledgeRetrievalNode.execute()` 第一行加 5 行:拿 user_id(已有 `user_ids`),调 `memory_service.get_user_summary(user_id)`,把 summary 拼到 query 前。
|
||||
- 新增 feature flag `MEMORY_AUGMENT_RETRIEVAL = false`(默认关闭)。
|
||||
- 不改 prompt,不改 schema,不改 ES。
|
||||
|
||||
**预期收益**:在多轮对话场景下,第 N 轮 query 的指代消解正确率提升;无回归风险(flag 默认关)。
|
||||
|
||||
```python
|
||||
# workflow/nodes/knowledge/node.py:KnowledgeRetrievalNode.execute() 头部增量
|
||||
if os.getenv("MEMORY_AUGMENT_RETRIEVAL") == "true" and user_ids:
|
||||
from app.services.user_memory_service import get_user_summary
|
||||
summary = get_user_summary(user_ids[0], ttl_sec=3600) # 已存在 / 类似函数
|
||||
if summary:
|
||||
query = f"[用户背景: {summary}]\n{query}"
|
||||
```
|
||||
|
||||
> **注意**:上述两段代码均为 PoC 草案,真实落地需要:1)完整单测;2)评估对比;3)feature flag 走配置中心;4)权限审查(D4 涉及隐私)。

|
||||
## 6. 与 [S3-T1] / [S3-T3] 的对齐清单
|
||||
|
||||
- ✅ 每个方向都标注了"接口改造点",所有改造均落到 [S3-T1] 提议的 `Retriever / Reranker / Embedder / Generator / GraphStore / Loader` Protocol;不新增其它接口。
|
||||
- ✅ 所有方向有"工作量、风险、依赖"三件套,可被 [S3-T3] 终审按统一模板核对。
|
||||
- ✅ Quick PoC 已覆盖 D2 与 D4 各 1 条(≥ 2 条要求达成)。
|
||||
- ✅ 优先级建议已按"用户价值 × 实现成本 × 风险"三维评分给出,并配有路线图甘特图。
|
||||
- ✅ 多模态、混合搜索、KG 增强、对话记忆、评估闭环均覆盖(5/5);额外补充自适应路由作为联动方向。

## 1. 一句话定位
|
||||
|
||||
GraphRAG 是 MemoryBear 知识库系统的**知识图谱增强检索模块**,通过 LLM 从文档中抽取实体-关系三元组构建知识图谱,在检索阶段利用图谱结构(实体关联、社区报告、多跳路径)补充传统向量检索的语义盲区,实现"结构化知识 + 语义向量"的混合召回。

## 5. Light vs General 差异
|
||||
|
||||
| 维度 | Light | General |
|
||||
|---|---|---|
|
||||
| 实体抽取 Prompt | LightRAG 风格,含 content_keywords | MS GraphRAG 风格,更简洁 |
|
||||
| Gleaning 终止 | 自然语言 yes/no | 强制单字 Y(logit_bias) |
|
||||
| 实体消歧 | ❌ 不支持 | ✅ 支持 |
|
||||
| 社区发现 | ❌ 不支持 | ✅ Leiden 算法 |
|
||||
| 社区报告 | ❌ 不支持 | ✅ LLM 生成报告 |
|
||||
| 实体嵌入 | 仅实体名向量 | 支持 Node2Vec(备用) |
|
||||
| 思维导图 | ❌ 不支持 | ✅ 支持 |
|
||||
| 建图耗时 | ~5-15 分钟 | ~30-60 分钟 |
|
||||
| 适用规模 | < 1K 文档 | > 1K 文档 |
|
||||
|
||||
**切换条件:** `parser_config["graphrag"]["method"] == "general"` 时启用 General,否则默认 Light。

## 1. Loader(数据加载层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | 外部系统:飞书 API、语雀 API、Web URL、用户上传接口 |
|
||||
| **输入** | 飞书:folder_token, app_id, app_secret;语雀:user_id, token;Web:entry_url, max_pages;上传:multipart/form-data |
|
||||
| **输出** | **原始文件内容**:`CrawledDocument` (dataclass) 或 **本地文件路径** (.docx/.pdf/.md/.html/.xlsx) |
|
||||
| **输出数据结构** | `CrawledDocument(url, title, content, content_length, crawl_timestamp, metadata)`;本地文件:`str` (path) |
|
||||
| **下游** | Parser:接收文件路径或 bytes,调用对应 format-specific parser |
|
||||
| **边界约定** | Loader 不做任何格式解析(不提取正文、不做 OCR)。仅负责:鉴权 → 获取/下载 → 存盘。格式识别由 Parser 层的 `naive.chunk()` 根据文件扩展名决定。 |
|
||||
|
||||
---
|
||||
|
||||
## 2. Parser(文档解析层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Loader:接收文件路径 `str` 或二进制 `bytes` |
|
||||
| **输入** | `(filename: str, binary: bytes \| None, from_page, to_page, callback, vision_model)` |
|
||||
| **输出** | `sections: List[Tuple[str, str]]` — (text_content, layout_tag);`tables: List[Tuple[Tuple[Optional[Image.Image], Union[str, List[str]]], List[Tuple]]]` |
|
||||
| **输出数据结构** | 元组列表,其中 tag 表示布局类型("Title"/"Text"/"Table"/...),text 可能含位置标签 `@@page\tx0\tx1\ttop\tbottom##` |
|
||||
| **下游** | Chunking:接收 `sections` + `tables`,执行合并与分块 |
|
||||
| **边界约定** | Parser 负责格式-specific 的**纯提取**,不负责语义分块。PDF Parser 特殊:需输出 OCR 结果 + 布局信息 + 表格 HTML。Parser 之间互不调用——由 `naive.chunk()` 统一 dispatch。 |
|
||||
|
||||
---
|
||||
|
||||
## 3. Chunking(文本分块层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Parser:`sections` + `tables` |
|
||||
| **输入** | `sections: List[Tuple[str, str]]`, `tables`, `chunk_token_num: int`, `delimiter: str`, `parser_config: dict` |
|
||||
| **输出** | `res: List[Dict]` — 分块后的文档字典列表 |
|
||||
| **输出数据结构(关键字段)** | `content_with_weight: str`(原始文本), `content_ltks: str`(粗粒度分词), `content_sm_ltks: str`(细粒度分词), `image: PIL.Image`(可选), `page_num_int: int`, `position_int: List[int]`, `top_int: int`, `doc_type_kwd: str` |
|
||||
| **下游** | Embedding:接收 `res`,提取 `content_with_weight` 进行向量化;GraphRAG:接收 `res` 中的文本进行实体关系抽取 |
|
||||
| **边界约定** | Chunking 不调用 Embedding,也不直接写入 VDB。它只负责将长文本切分成符合 token 预算的 chunks,并填充分词/位置元数据。多模态(图片/音频)的分块结果也统一为此数据结构。 |
|
||||
|
||||
---
|
||||
|
||||
## 4. Embedding(向量化层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Chunking:接收 chunk dicts 的 `content_with_weight` |
|
||||
| **输入** | `texts: List[str]`(batch,默认 ≤16 条) |
|
||||
| **输出** | `(np.array, total_tokens)` — `np.array` shape `(batch_size, vector_dimension)` |
|
||||
| **输出数据结构** | NumPy ndarray,float32;向量维度由模型决定(如 OpenAI text-embedding-3: 1536d) |
|
||||
| **下游** | VDB:接收 `(chunk_text, vector, metadata)` 组装成 `DocumentChunk` 后入库 |
|
||||
| **边界约定** | Embedding 层无状态,不管理模型生命周期。Provider 通过工厂模式实例化(`Base._FACTORY_NAME` 匹配)。输入文本超长时自动截断(OpenAI 截到 8000 tokens,QWen 截到 2048)。支持 `encode_queries()` 单条 query 编码。 |
|
||||
|
||||
---
|
||||
|
||||
## 5. VDB(向量数据库层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Embedding:接收 `(text, vector, metadata)`;Chunking:接收 chunk dicts 中的 metadata |
|
||||
| **输入** | `DocumentChunk(page_content: str, vector: List[float], metadata: dict)`;或检索时:`query: str, top_k: int, indices: str, score_threshold: float` |
|
||||
| **输出(入库)** | ack / error;**输出(检索)**:`List[DocumentChunk]` |
|
||||
| **存储 Schema** | `page_content: text(ik_max_word)`, `metadata: object(doc_id, document_id, knowledge_id, sort_id, status)`, `vector: dense_vector(cosine, dynamic_dims)` |
|
||||
| **下游** | Retrieval:通过 `search_by_vector` / `search_by_full_text` / `search` (hybrid) 获取结果 |
|
||||
| **边界约定** | VDB 同时承担**文档存储**(全文索引)和**向量存储**(密集向量索引)双重职责。ES 是唯一的后端(无 Milvus/Pinecone 等)。GraphRAG 的实体/关系/社区报告也以相同 chunk 格式存储于此。 |
|
||||
|
||||
---
|
||||
|
||||
## 6. GraphRAG(知识图谱层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Chunking:接收 chunk dicts 的 `content_with_weight`;Celery:异步触发 `build_graphrag_for_document` |
|
||||
| **输入(索引)** | `(document_id, chunk_text)` tuples;`chat_model: Base`, `embedding_model: OpenAIEmbed`, `vector_service: ElasticSearchVector` |
|
||||
| **输入(检索)** | `question: str, workspace_ids: List[str], kb_ids: List[str], emb_mdl, llm` |
|
||||
| **输出(索引)** | `nx.Graph`(全局图)存储到 ES;`entity` chunks + `relation` chunks + `community_report` chunks(General only) |
|
||||
| **输出(检索)** | `Dict` with `page_content` = "Entities CSV + Relations CSV + Community Reports",`metadata` 含引用信息 |
|
||||
| **下游** | VDB:索引/存储实体、关系、社区报告 chunks;Retrieval:`KGSearch.retrieval()` 返回的 chunk 被 `insert(0, ...)` 插入标准检索结果 |
|
||||
| **边界约定** | GraphRAG 是**独立异步流程**,不与标准 RAG 索引同步。Light 和 General 共享相同的存储格式但 General 多出 community_report。GraphRAG 不替代 VDB,而是**在 VDB 之上增加图语义层**。检索时 KG 结果优先级最高(insert at position 0)。 |
|
||||
|
||||
---
|
||||
|
||||
## 7. Retrieval(检索层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | VDB:通过 `search_by_vector` / `search_by_full_text` 获取候选;GraphRAG:`KGSearch.retrieval()` 获取图语义结果;Workflow Node:`KnowledgeRetrievalNode.execute()` 发起调用 |
|
||||
| **输入** | `query: str, config: Dict(knowledge_bases[], merge_strategy, reranker_id, reranker_top_k, use_graph)` |
|
||||
| **输出** | `List[DocumentChunk]` — 按相关性降序排列的文档块 |
|
||||
| **输出数据结构** | `DocumentChunk(page_content: str, metadata: dict)`,其中 metadata 含 `score`, `doc_id`, `document_id`, `knowledge_id`, `highlight` |
|
||||
| **下游** | Reranking:接收候选列表,可选执行重排序;Prompt:接收 chunks 组装上下文 |
|
||||
| **边界约定** | Retrieval 层支持 4 种模式:PARTICIPLE(全文)、SEMANTIC(向量)、HYBRID(混合)、GRAPH(图增强)。多 KB 时逐 KB 检索后合并。HYBRID 的默认权重为 BM25 0.05 + Vector 0.95。检索失败(空结果)时自动降级(min_match 0.1 + similarity 0.17 重试)。 |
|
||||
|
||||
---
|
||||
|
||||
## 8. Reranking(重排序层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Retrieval:接收候选 `List[DocumentChunk]` |
|
||||
| **输入** | `query: str, docs: List[DocumentChunk], top_k: int`;或 `reranker_id: UUID` |
|
||||
| **输出** | `List[DocumentChunk]` — 重排序后的文档块(长度 ≤ top_k) |
|
||||
| **输出数据结构** | 同 Retrieval 输出,metadata 中更新 `score` 为重排序后的分数 |
|
||||
| **下游** | Prompt:接收重排序后的 chunks 组装上下文 |
|
||||
| **边界约定** | Reranking 是**可选层**。未配置 reranker_id 时,HYBRID 结果按 metadata.score 降序截断。配置了 reranker_id 时,调用外部 Rerank API(Jina / DashScope / Xinference)。Rerank 失败时**降级**到原始结果(不阻断流程)。 |
|
||||
|
||||
---
|
||||
|
||||
## 9. Prompt(Prompt 组装层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Reranking:接收排序后的 chunks;Workflow:接收用户 query |
|
||||
| **输入** | `chunks: List[DocumentChunk], query: str, system_prompt: str`(可选) |
|
||||
| **输出** | `system: str, history: List[Dict]` — LLM 可调用的消息格式 |
|
||||
| **输出数据结构** | `system: str`(含检索上下文 + 系统指令),`history: [{"role": "user", "content": query}]` |
|
||||
| **下游** | LLM:`Base.chat(system, history, gen_conf)` |
|
||||
| **边界约定** | Prompt 层**不**调用 LLM,只负责**文本组装**。组装逻辑包括:citation_prompt(引用标注格式)、keyword_extraction(用于缓存 key)、content_tagging(内容分类)。Prompt 模板以 `.md` 文件形式存储在 `prompts/` 目录,通过 `template.py` 动态加载。 |
|
||||
|
||||
---
|
||||
|
||||
## 10. LLM(大模型生成层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | Prompt:接收 `system` + `history` |
|
||||
| **输入** | `system: str, history: List[Dict], gen_conf: dict(temperature, top_p, max_tokens)` |
|
||||
| **输出** | `(answer: str, tokens: int)` 或流式 `Generator[str \| int]` |
|
||||
| **输出数据结构** | 字符串(生成的回答文本);流式模式下逐 token 返回 |
|
||||
| **下游** | Post-Process:`insert_citations()` 插入引用标注 |
|
||||
| **边界约定** | LLM 层**无上下文记忆**(stateless),每次调用携带完整 history。支持 10+ Provider,通过 `_FACTORY_NAME` 工厂模式匹配。流式输出通过 `chat_streamly()` 实现,返回 Generator。错误处理:API 异常时抛出,由上层(Workflow / Celery)捕获。 |
|
||||
|
||||
---
|
||||
|
||||
## 11. Post-Process(后处理层)
|
||||
|
||||
| 维度 | 定义 |
|
||||
|------|------|
|
||||
| **上游** | LLM:接收生成的 `answer`;Retrieval:接收原始 `chunks` + `chunk_v`(向量) |
|
||||
| **输入** | `answer: str, chunks: List[DocumentChunk], chunk_v: List[np.array], embd_mdl, tkweight, vtweight` |
|
||||
| **输出** | `(answer_with_citations: str, cited_ids: Set[str])` |
|
||||
| **输出数据结构** | 字符串(含 `[1]`, `[2]` 等引用标记),`Set[str]`(被引用的 chunk id 集合) |
|
||||
| **下游** | User:最终展示;Cache:写入 Redis 缓存 |
|
||||
| **边界约定** | Post-Process 只做**引用标注插入**(`insert_citations()`),不做内容修改。引用定位算法基于 `pagerank * similarity` 评分。代码块(```...```)内**不**插入引用。缓存键由 `(model_name, prompt_text)` 组合生成,TTL 由 Redis 配置决定。 |

## 留白与重叠风险点
|
||||
|
||||
| 风险区域 | 说明 | 建议归属 |
|
||||
|----------|------|----------|
|
||||
| **Parser ↔ Chunking 边界** | Parser 输出的 `sections` 格式(含 tag 和位置信息)被 Chunking 的 `naive_merge` 直接消费。若 Parser 改了 tag 格式,Chunking 会受影响。 | **统一在 Parser 文档中定义 `sections` 数据契约**,Chunking 文档只引用该契约。 |
|
||||
| **Embedding ↔ VDB 边界** | Embedding 输出维度必须与 VDB mapping 中 `dense_vector` 的 dims 一致。动态维度由首次 encode 决定。 | **Embedding 文档声明维度获取方式**,VDB 文档只引用。 |
|
||||
| **GraphRAG ↔ VDB 边界** | GraphRAG 的实体/关系/社区报告以 `DocumentChunk` 格式存入 VDB,与标准 chunk 共用同一 ES index。 | **VDB 文档定义通用存储格式**,GraphRAG 文档只说明使用了该格式。 |
|
||||
| **Retrieval ↔ Reranking 边界** | Retrieval 的 HYBRID 模式在 Node 层已做 dedup,但 `knowledge_retrieval()` 函数也有独立 rerank 调用。 | **Reranking 文档**说明两种调用路径(Node 层 vs 函数层)的区别。 |
|
||||
| **Prompt ↔ LLM 边界** | Prompt 组装的 `history` 格式必须与各 Provider 的 API 格式兼容。 | **Prompt 文档**声明输出格式规范,LLM 文档说明各 Provider 的适配。 |

## 三、入口链路梳理
|
||||
|
||||
### 3.1 文档入库链路(Indexing Pipeline)
|
||||
|
||||
```
|
||||
REST POST /document 或 /knowledge/{id}/sync

↓ 调用
|
||||
rag/app/naive.py:508 chunk(filename, binary, ...)
|
||||
↓ 路由 by file extension
|
||||
├─ PDF → by_deepdoc() → deepdoc/parser/pdf_parser.py:34 RAGPdfParser.__call__:1124
|
||||
├─ PDF alt → by_mineru() → deepdoc/parser/mineru_parser.py:41 MinerUParser.parse_pdf()

|
||||
↓
|
||||
rag/app/naive.py:257 naive.__call__() — 提取 sections + tables
|
||||

||||
rag/vdb/elasticsearch/elasticsearch_vector.py:55 add_chunks()
|
||||
↓ 调用
|
||||
rag/vdb/elasticsearch/elasticsearch_vector.py:65 create()
|
||||
↓ 调用
|
||||
embedding_model.py: encode() → LLM API → ES bulk index
|
||||
```
|
||||
|
||||
### 3.2 在线检索链路(Query Pipeline)
|
||||
|
||||
```
|
||||
REST POST /retrieval
|
||||
或
|
||||

|
||||
↓ 调用
|
||||
rag/common/settings.py:10 kg_retriever (单例)
|
||||
↓ 调用
|
||||
rag/graphrag/search.py:19 KGSearch.retrieval()
|
||||
```
|
||||
|
||||
### 3.3 GraphRAG 构建链路
|
||||
|
||||
```
|
||||

|
||||
↓
|
||||
rag/graphrag/general/index.py:122 run_graphrag_for_kb(kb_id, ...)
|
||||
↓ 流水线
|
||||
1. init_graphrag() → 创建 ES 索引
|
||||
2. GraphExtractor.extract() → 逐 chunk 抽取实体/关系
|
||||
├─ general/graph_extractor.py:34 GraphExtractor (Microsoft GraphRAG 风格)
|
||||
└─ light/graph_extractor.py:31 GraphExtractor (LightRAG 风格,条件切换)
|
||||
3. graph_merge() → 合并子图

## 四、Gap 报告(代码 vs S1-T2 架构预期)
|
||||
|
||||
### 4.1 "架构里列了但代码里没有 / 命名/范围不一致"
|
||||
|
||||
| # | 差异项 | S1-T2 架构预期 | 代码实际 | 影响与建议 |
|
||||
|---|---|---|---|---|
|
||||
| 1 | **缺少 Milvus/Weaviate/Qdrant 支持** | VDB 环节预期讨论"向量数据库选型",暗示可能多库 | 仅 `rag/vdb/elasticsearch/` 有实现,`BaseVector` 无其他子类 | 架构文档中 VDB 章节需要明确限定为 Elasticsearch 8.x,或规划扩展接口 |
|
||||
| 2 | **`rag_utils` vs `rag/utils` 命名冲突** | 预期目录:`api/app/core/rag/{deepdoc,crawler,integrations,llm,vdb,graphrag,prompts,app}` | 实际存在 `rag/utils`(文件工具/ES 连接)**和** `rag_utils/`(Chunk LLM 分析)两个独立目录,仅下划线差异 | 极易混淆,建议将 `rag_utils/` 重命名为 `rag/chunk_analytics/` 或合并到 `rag/app/` 下游 |
|
||||
| 3 | **`nlp/search.py` 中的 `Dealer` 是遗留/旁路模块** | 架构中 `rag/nlp` 预期为"分词/NLP 工具" | `rag/nlp/search.py:349 Dealer` 实际是一个完整的 BM25/hybrid 搜索调度器,与 `rag/vdb` 的 ES 向量搜索并行存在两套检索体系 | 两套检索代码并存(`nlp/search.py` 主要被 GraphRAG 使用,`vdb/elasticsearch` 被 Workflow 使用)。架构文档应明确标注 `nlp/search` 是 GraphRAG 专用旧通道 |
|
||||
| 4 | **缺少独立的 Reranking 模块** | S1-T2 预期有独立的 Reranking 环节 | 重排序逻辑散布在多处:`workflow/nodes/knowledge/node.py:108 rerank()`、`rag/vdb/elasticsearch/elasticsearch_vector.py:560 rerank()`、以及 `rag/nlp/search.py:606 rerank()` | 建议 Sprint-2 文档将 Reranking 单独成章,汇总这三处实现并标注差异(Workflow 节点用 RedBearRerank,VDB 层也有独立 rerank,NLP 层有 model-based rerank) |
|
||||
| 5 | **Prompt 目录含大量 .md 模板但无统一版本管理** | Prompt 工程是独立环节 | `rag/prompts/` 有 31 个 `.md` 模板文件 + `template.py`(加载器)+ `generator.py`(工厂函数),但模板修改无版本控制/审计机制 | 建议文档中标注 prompt 管理现状:文件驱动、运行时加载、无 A/B 或版本回滚机制 |
|
||||
| 6 | **Deepdoc vision 模型加载路径硬编码** | 架构预期模型管理可配置 | `deepdoc/vision/` 各 recognizer 硬编码从 `huggingface_hub.snapshot_download(repo_id="InfiniFlow/deepdoc")` 下载到 `res/deepdoc/`,仅 `HF_ENDPOINT` 环境变量可配 | 建议文档中明确标注模型路径约束,为后续模型热更新/私有化部署做铺垫 |
|
||||
| 7 | **GraphRAG light 是条件分支而非独立模块** | S1-T2 预期 GraphRAG 有 light 和 general 两个独立目录 | `light/` 仅含 `graph_extractor.py` + `graph_prompt.py`(2 个逻辑文件),其余全部复用 `general/` 的 `Extractor` 基类、`utils.py`、`index.py` | Sprint-2 文档应将 light 标记为"general 的条件子模式",避免读者误以为两套完整流水线 |
|
||||
|
||||
### 4.2 "代码里有但架构没列"
|
||||
|
||||
| # | 差异项 | 代码位置 | 说明 |
|
||||
|---|---|---|---|
|
||||
| 1 | **rag/app 按 doc_type 路由的 11 种解析策略** | `rag/app/{naive,book,paper,qa,audio,picture,manual,laws,mail,one,textin_parser}.py` | S1-T2 架构只提到 "Loader / Parser",未提及 MemoryBear 特有的 doc_type 路由体系(book/paper/qa/audio 等) |
|
||||
| 2 | **MinerU 第三方解析器集成** | `rag/deepdoc/parser/mineru_parser.py` | 架构中 Parser 环节未提及 MinerU(第三方 PDF 解析服务)作为 PDF 解析的替代方案 |
|
||||
| 3 | **TextIn 第三方解析器集成** | `rag/app/textin_parser.py` | 同上,未提及 TextIn API 作为另一 PDF 解析备选 |
|
||||
| 4 | **rag_utils(Chunk LLM 分析)** | `api/app/core/rag_utils/` | 架构中无此模块定位,它实际做 chunk 摘要/标签/洞察,与 Memory 系统耦合 |
|
||||
| 5 | **Toc(目录)智能提取链路** | `rag/prompts/generator.py:408-717` | 大量 LLM-driven TOC 检测/提取/索引/关联代码,架构大纲中未单列 "TOC 处理" 环节 |
|
||||
| 6 | **Crawler(网页抓取)** | `rag/crawler/` | 架构中 Loader 环节可能包含爬虫,但代码量 1,200+ LOC 值得单独标注 |
|
||||
| 7 | **res/ 静态资源(NER、同义词表)** | `rag/res/{ner.json,synonym.json,mapping.json}` | 架构中未提及术语权重/同义词扩展的资源文件体系 |

## 0. 一句话定位
|
||||
|
||||
把"任意来源、任意格式"的原始资料,沉淀为带元数据、可被 Embedding/索引消费的标准化 **Chunk** 序列;这一段是 RAG 召回质量的"硬天花板"——它做不好,下游再多优化都救不回来。
|
||||
|
||||
## 1. 设计目标与适用场景
|
||||
|
||||
| 目标 | 落地策略 |
|
||||
|---|---|
|
||||
| 多源接入(爬虫 / 飞书 / 语雀 / 本地文件) | `crawler/`、`integrations/feishu`、`integrations/yuque` 三套 SDK,均落到本地文件后再走统一 `chunk()` 入口 |
|
||||
| 多格式解析(PDF/Word/Excel/PPT/HTML/MD/JSON/TXT/图片/音视频) | `app/naive.py:chunk()` 单一编排入口,按扩展名分派到 `deepdoc/parser/*` 与 `app/{audio,picture}.py` |
|
||||
| 复杂 PDF 还原(表格、图、版面) | `RAGPdfParser` + OCR + 版面识别 + TSR + XGBoost 段落连接模型 |
|
||||
| 长文 Chunking 既保语义又控 token | `naive_merge` / `naive_merge_docx` / `hierarchical_merge` / `tree_merge` 多种策略,统一以 `cl100k_base` 计算 token |
|
||||
| 同一篇资料的多模态(图 + 文 + 表) | `tokenize_chunks_with_images`、`tokenize_table` 把图片/表格作为附属信息挂在 chunk 上 |
|
||||
| 健壮性 | 鉴权 token 缓存、退避重试、robots.txt 合规、编码自动嗅探、嵌入文件递归解构 |
|
||||
|
||||
适用于:私有知识库、企业文档库、技术资料归档;不适用于:实时流式数据、对端到端延迟<200ms 的场景(OCR 与版面识别是 CPU/GPU 重负载)。
|
||||
|
||||
## 2. 术语表
|
||||
|
||||
- **Section**:解析器吐出的中间结构 `(text, position_or_layout)` 元组列表,是 Chunking 之前的"原料"。
|
||||
- **Chunk**:最终交给 Embedding 的文本片段,一般 ≤ `chunk_token_num` 个 token(默认 128–512)。
|
||||
- **Token**:用 `tiktoken.cl100k_base` 编码后得到的 BPE token 数(与 OpenAI gpt-4 同口径)。
|
||||
- **Layout**:页面区块类别(title / text / figure / table / equation 等),由 YOLOv10 检测。
|
||||
- **TSR**:Table Structure Recognition,复杂表格行/列/合并单元格的结构还原。
|
||||
- **OCR**:文字检测 + 文字识别两阶段的图像字符抽取。
|
||||
- **Embed file**:内嵌在 docx/xlsx/pptx 内部的子文件(如 docx 里嵌的 Excel),需递归解析。

## 4. Loader 章节
|
||||
|
||||
### 4.1 Web Crawler(`crawler/`)
|
||||
|
||||
- **入口**:`WebCrawler(entry_url, max_pages, delay_seconds, timeout_seconds, user_agent, include_patterns, exclude_patterns)`,源码 `api/app/core/rag/crawler/web_crawler.py:19`。
|
||||
- **架构**:BFS(`deque` + `visited_urls`)+ 五个独立组件:`URLNormalizer` / `RobotsParser` / `RateLimiter` / `HTTPFetcher` / `ContentExtractor`,全部通过组合而非继承装配,便于替换。
|
||||
- **同域限制**:`URLNormalizer.is_same_domain()` 强制只爬入口域名,避免无界扩散(`url_normalizer.py:102-124`)。
|
||||
- **去重**:`URLNormalizer.normalize()` 做:小写 host、去 fragment、去默认端口、剥离 utm_*/fbclid/gclid 等追踪参数、按字母序排 query。`url_normalizer.py:28-100`。
|
||||
- **robots.txt 合规**:`RobotsParser.can_fetch()` 与 `get_crawl_delay()`,使用 stdlib 的 `urllib.robotparser`,每域名缓存。robots.txt 拉取失败时**默认允许**(permissive fallback),`robots_parser.py:60-69`。

||||
- **限速**:`RateLimiter` 默认 1s/请求,`set_delay()` 可被 `Crawl-delay` 动态覆盖(上限 60s 防呆);`backoff(2.0)` 用于 429/503 指数退避,`rate_limiter.py:38-58`。
|
||||
- **HTTP 重试**:`HTTPFetcher` 内置 `max_retries=3`,退避 `1s → 2s → 4s`;429 与 503 显式触发重试,404/4xx 立即返回不重试,5xx 重试到耗尽。`http_fetcher.py:54-180`。
|
||||
- **编码处理**:`HTTPFetcher._get_decoded_content` 五级回退:HTML meta charset → response.encoding(跳过 ISO-8859-1) → UTF-8 → GBK/Big5/Shift-JIS/EUC-KR 等 → latin-1 with errors='replace'。`http_fetcher.py:182-248`。
|
||||
- **正文抽取**:`ContentExtractor.extract` 基于 `lxml`:移除 `script/style/nav/header/footer/aside`,按 `<article>/<main>` → `[role=main]` → `class/id =~ content|main|article|post` → `<body>` 顺序找主体;用 `is_static_content` 检测"脚本多文本少"的 SPA 页面并直接跳过。`content_extractor.py:24-72`。
|
||||
- **错误统计**:`stats.error_breakdown` 记录每种错误类型的计数,便于事后分析。`web_crawler.py:210-215`。
|
||||
|
||||
```python
|
||||
# api/app/core/rag/crawler/web_crawler.py:103-145(节选)
|
||||
while self.url_queue and self.pages_processed < self.max_pages:
|
||||
url = self.url_queue.popleft()
|
||||
if url in self.visited_urls: continue
|
||||
self.visited_urls.add(url)
|
||||
if not self.robots_parser.can_fetch(url): # robots.txt
|
||||
self.stats['skipped'] += 1; continue
|
||||
self.rate_limiter.wait() # 限速
|
||||
fetch_result = self.http_fetcher.fetch(url) # 重试 + 退避
|
||||
if not fetch_result.success:
|
||||
self._record_error(fetch_result.error or "Unknown error"); continue
|
||||
content_type = fetch_result.headers.get('Content-Type', '').lower()
|
||||
if not any(s in content_type for s in ['text/html', 'application/xhtml+xml']):
|
||||
self.stats['skipped'] += 1; continue # 非 HTML 跳过
|
||||
extracted = self.content_extractor.extract(fetch_result.content, url)
|
||||
if not extracted.is_static:
|
||||
self.stats['skipped'] += 1; continue # JS-only 站点跳过
|
||||
```
|
||||
|
||||
### 4.2 飞书集成(`integrations/feishu/`)
|
||||
|
||||
- **入口**:`FeishuAPIClient(app_id, app_secret, api_base_url, timeout, max_retries)`,`integrations/feishu/client.py:24`,是异步客户端(`httpx.AsyncClient`),用 `async with` 管理生命周期。
|
||||
- **鉴权**:`tenant_access_token` 模式,`get_tenant_access_token()` 用 `cachetools.TTLCache(maxsize=1, ttl=7200-300)` 缓存(飞书原生 2 小时有效,提前 5 分钟失效)+ `asyncio.Lock` 双检锁防并发请求 token。`client.py:51-127`。
|
||||
- **文件类型分派**:`download_document` 按 `document.type` 分两条路径:
|
||||
- **在线文档(doc/docx/sheet/bitable)**:`_export_file` 走"创建导出任务 → 轮询 ticket → 下载 file_token"三步,最多轮询 10 次、间隔 2s,超时抛 `FeishuAPIError`。`client.py:311-406`。
|
||||
- **附件文件(file/slides)**:`_download_file` 直接 GET `/drive/v1/files/{token}/download`,从 `Content-Disposition` 解析 `filename*=UTF-8''xxx` 编码文件名。`client.py:408-452`。
|
||||
- **限流与重试**:装饰器 `@with_retry`(`feishu/retry.py:124-137`)。`RetryStrategy.RETRYABLE_ERRORS = (FeishuNetworkError, FeishuRateLimitError, httpx.TimeoutException/ConnectError/ReadError)`,`MAX_RETRIES=3`,退避 `[1, 2, 4]s`;HTTP 429/502/503/5xx 重试,4xx(除 429)不重试;飞书业务码 `99991400/99991401`(限流码)也强制重试。`feishu/retry.py:24-76`。
|
||||
- **错误模型**:精细化异常树 `FeishuAuthError / FeishuAPIError / FeishuNotFoundError / FeishuPermissionError / FeishuRateLimitError / FeishuNetworkError / FeishuDataError`,调用方据此决定告警级别。`feishu/exceptions.py:1-46`。
|
||||
- **分页与递归**:`list_folder_files` 单页(page_size=200);`list_all_folder_files(recursive=True)` 自动展开子文件夹。`client.py:226-269`。
|
||||
|
||||
```python
|
||||
# api/app/core/rag/integrations/feishu/client.py:78-120(鉴权 + 双检锁缓存)
|
||||
cached_token = self._token_cache.get("access_token")
|
||||
if cached_token: return cached_token
|
||||
async with self._token_lock:
|
||||
cached_token = self._token_cache.get("access_token")
|
||||
if cached_token: return cached_token
|
||||
response = await self._http_client.post(
|
||||
"/auth/v3/tenant_access_token/internal",
|
||||
json={"app_id": self.app_id, "app_secret": self.app_secret})
|
||||
data = response.json()
|
||||
if data.get("code") != 0:
|
||||
raise FeishuAuthError(f"Authentication failed: {data.get('msg')}",
|
||||
error_code=str(data.get("code")), details=data)
|
||||
token = data.get("tenant_access_token")
|
||||
self._token_cache["access_token"] = token
|
||||
return token
|
||||
```
|
||||
|
||||
### 4.3 语雀集成(`integrations/yuque/`)
|
||||
|
||||
- **入口**:`YuqueAPIClient(user_id, token, api_base_url, timeout, max_retries)`,`integrations/yuque/client.py:27`。
|
||||
- **鉴权**:个人 PAT,HTTP header `X-Auth-Token`,无需 OAuth/token 刷新(语雀的 token 是长期 token),故没有 token 缓存层。`client.py:55-66`。
|
||||
- **API 三段式**:`get_user_repos()` → `get_repo_docs(book_id)` → `get_doc_detail(id, raw=1)`;`get_doc_detail` 用 `params={"raw": 1}` 拉原始 markdown。`client.py:119-291`。
|
||||
- **格式分派(download_document)**:根据 `doc.format` 决定本地文件后缀:
|
||||
- `markdown` / `lake` → `.md`(lake 也按 markdown 保存,因为 lake 在 raw 模式下输出兼容 md)
|
||||
- `html` → `.html`
|
||||
- `lakesheet` → `.xlsx`,需 `zlib.decompress(bytes(sheet_data, 'latin-1'))` 解压后由 `generate_excel_from_sheet` 用 openpyxl 重建工作簿(含字体、对齐、颜色、合并单元格)。`client.py:293-545`。
|
||||
- **限流与重试**:与飞书同构,`yuque/retry.py:21-118`,`RetryStrategy` 配置一致;HTTP 状态码 401→`YuqueAuthError`、403→`YuquePermissionError`、404→`YuqueNotFoundError`、429→`YuqueRateLimitError`,由 `_handle_api_error` 统一翻译。`client.py:73-117`。
|
||||
- **健壮性**:`get_user_repos`/`get_repo_docs` 对单条数据 `try/except` 跳过坏记录而不整体失败(容忍语雀 schema 漂移)。`client.py:158-160, 221-223`。
|
||||
|
||||
### 4.4 本地文件(`app/naive.py:chunk`)
|
||||
|
||||
- 是所有 Loader 的最终汇入口;接收 `filename` 与 `binary` 两种入参,二者互斥(推荐 `binary`,源码内 `extract_embed_file` 显式不支持 path 模式,详见 `app/naive.py:541`)。
|
||||
- **嵌入文件递归**:根调用(`is_root=True`)会先用 `extract_embed_file()` 抽出 docx/xlsx/pptx 内部嵌入的子文件(通过 zip 名单 `word/embeddings/`、`xl/embeddings/`、`ppt/embeddings/` 或 OLE 容器的 `Ole10Native`),逐个递归 `chunk()`,结果合入 `embed_res`。`utils/file_utils.py:69-130` + `app/naive.py:533-552`。
|
||||
- **超链接深挖**:`parser_config.analyze_hyperlink=True` 时,docx/pdf 内部超链接经 `extract_links_from_docx` / `extract_links_from_pdf` 抽出后,每条 URL 调用 `extract_html` 拉回 HTML 二进制并递归 `chunk(url, html_bytes, is_root=False)`。`app/naive.py:556-566, 793-803`。
|
||||
- **callback 进度上报**:`chunk(..., callback=progress_callback)`,约定 `callback(prog: float, msg: str)`,关键节点:0.05(嵌入抽取)/ 0.1(开始解析)/ 0.6(OCR 完)/ 0.63(版面)/ 0.65(表格)/ 0.67(合并)/ 0.8(解析完)。
|
||||
|
||||
## 5. Parser 章节
|
||||
|
||||
### 5.1 总分派器(`app/naive.py`)
|
||||
|
||||
`chunk()` 是入口,按文件扩展名走分支:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/app/naive.py:97-102
|
||||
PARSERS = {
|
||||
"deepdoc": by_deepdoc,
|
||||
"mineru": by_mineru,
|
||||
"textln": by_textln,
|
||||
"plaintext": by_plaintext, # default
|
||||
}
|
||||
# api/app/core/rag/app/naive.py:553-764
|
||||
if re.search(r"\.docx$", filename, re.IGNORECASE): ...
|
||||
elif re.search(r"\.pdf$", filename, re.IGNORECASE): ... # 走 PARSERS dict
|
||||
elif re.search(r"\.(pptx|ppt?)$", ...): ... # LibreOffice → pdf
|
||||
elif re.search(r"\.(da|wav|mp3|...)$", ...): ... # app/audio.py
|
||||
elif re.search(r"\.(png|jpeg|...)$", ...): ... # app/picture.py
|
||||
elif re.search(r"\.(csv|xlsx?)$", ...): ExcelParser
|
||||
elif re.search(r"\.(txt|py|js|java|...)$", ...): TxtParser
|
||||
elif re.search(r"\.(md|markdown)$", ...): Markdown(MarkdownParser 子类)
|
||||
elif re.search(r"\.(htm|html)$", ...): HtmlParser
|
||||
elif re.search(r"\.(json|jsonl|ldjson)$", ...): JsonParser
|
||||
elif re.search(r"\.doc$", ...): tika # Apache Tika via JVM
|
||||
```
|
||||
|
||||
PDF 的 `parser_config.layout_recognize` 决定底层走哪条 PDF 引擎,默认 `DeepDOC`:
|
||||
|
||||
| layout_recognize | 引擎 | 调用 | 适用 |
|
||||
|---|---|---|---|
|
||||
| `DeepDOC` | `Pdf(RAGPdfParser)` | `by_deepdoc` | 复杂版面、扫描件 |
|
||||
| `Plain Text` | `PlainParser` | `by_plaintext` | 纯文本 PDF,速度快 |
|
||||
| `MinerU` | `MinerUParser` | `by_mineru` | 高质量结构化(外部进程或 HTTP) |
|
||||
| `TextLn` | `TextLnParser` | `by_textln` | TextIn API(云端付费) |
|
||||
| 任意(含 `vision_model`) | `VisionParser` | `by_plaintext` 分支 | 多模态 LLM 直读 |
|
||||
|
||||
### 5.2 PDF 解析(`deepdoc/parser/pdf_parser.py`,1387 行)
|
||||
|
||||
`RAGPdfParser` 是大头,调用栈:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/app/naive.py:373-412 (Pdf.__call__ 节选)
|
||||
self.__images__(filename if not binary else binary, zoomin, from_page, to_page, callback)
|
||||
callback(0.6, f"OCR finished")
|
||||
self._layouts_rec(zoomin) # 版面识别
|
||||
callback(0.63, "Layout analysis")
|
||||
self._table_transformer_job(zoomin) # TSR
|
||||
callback(0.65, "Table analysis")
|
||||
self._text_merge(zoomin=zoomin) # 文本合并
|
||||
self._extract_table_figure(...) # 提取表与图
|
||||
self._naive_vertical_merge()
|
||||
self._concat_downward() # XGBoost 段落连接(updown_concat_xgb)
|
||||
self._final_reading_order_merge()
|
||||
return [(b["text"], self._line_tag(b, zoomin)) for b in self.boxes], tbls
|
||||
```
|
||||
|
||||
要点:
|
||||
- **OCR**:`OCR()`(`deepdoc/vision/ocr.py:522`)= `TextDetector` + `TextRecognizer` 组合;`pdfplumber` 把每一页 `to_image(resolution=72*zoomin=216).annotated`,再过 OCR。`pdf_parser.py:1006-1122`。
|
||||
- **版面识别**:`LayoutRecognizer4YOLOv10`(默认,10 个 label:title / Text / Reference / Figure / Figure caption / Table / Table caption / Equation 等),或 `AscendLayoutRecognizer`(Ascend NPU),由 `LAYOUT_RECOGNIZER_TYPE` 环境变量切换。`pdf_parser.py:53-67` + `vision/layout_recognizer.py:147-160`。
|
||||
- **表格结构识别**:`TableStructureRecognizer`(`vision/table_structure_recognizer.py`),裁出 table 区域后把行/列重组成 HTML;与 docx 的"按上下文找最近标题"风格一致。`pdf_parser.py:178-220`。
|
||||
- **段落连接模型**:`updown_cnt_mdl`(XGBoost),输入是上下相邻两块的 31 维特征(句末是否标点、x0 距离、行内 token 数、字号差、layout_type 等),决定要不要把下一块续到上一块。`pdf_parser.py:113-156` + `pdf_parser.py:70-83`(模型从 HuggingFace `InfiniFlow/text_concat_xgb_v1.0` 拉)。
|
||||
- **位置标签**:每个文本块带 `@@<page>\t<x0>\t<x1>\t<top>\t<bottom>##` 的位置 tag,`remove_tag()` 用 `re.sub(r"@@[\t0-9.-]+?##", "", txt)` 去掉,`extract_positions()` 反解。`pdf_parser.py:1219-1229`。
|
||||
- **GPU 加速**:通过 `pip_install_torch()` + `torch.cuda.is_available()` 把 XGBoost 推到 CUDA;`PARALLEL_DEVICES > 1` 时用 `trio.CapacityLimiter` 做多卡并行。`pdf_parser.py:50-77, 1095-1106`。
|
||||
- **HuggingFace 模型分发**:`InfiniFlow/text_concat_xgb_v1.0` 通过 `snapshot_download` 拉到 `res/` 目录;推荐 `export HF_ENDPOINT=https://hf-mirror.com` 解决国内拉取慢,`deepdoc/README.md:42`。
|
||||
|
||||
#### 5.2.1 备选 PDF 引擎
|
||||
|
||||
- **`PlainParser`**(`pdf_parser.py:1300`):`pypdf.PdfReader` 直接 `extract_text()`,每行一段 + 解析 outline 目录;无 OCR、无版面、无图,纯文本极快。
|
||||
- **`VisionParser`**(`pdf_parser.py:1334`):把每一页转成 PIL.Image,整页直接喂给 `vision_model`(`QWenCV` / `AzureGptV4` 等),让多模态 LLM "看图说话"产出 markdown。`@@page\tx0\tx1\ty0\ty1##` 位置 tag 由 `(0, 0, width/zoomin, 0, height/zoomin)` 占位生成(即整页矩形),方便下游对齐 chunk 与原图。
|
||||
- **`MinerUParser`**(`mineru_parser.py:41`):调用外部 `mineru` 进程(CLI 模式)或 `MINERU_APISERVER`(HTTP 模式,默认 `host.docker.internal:9987`),后端可选 `pipeline / vlm-http-client / vlm-transformers / vlm-vllm-engine`;输出 zip 解压后融合为 sections + tables。`naive.py:45-62`。
|
||||
- **`TextLnParser`**(`app/textin_parser.py`):合合 TextIn 云端 PDF→Markdown 服务,需要 `TEXTLN_APP_ID/SECRET_CODE`。
|
||||
|
||||
### 5.3 Word 解析(`deepdoc/parser/docx_parser.py` + `naive.py:Docx`)
|
||||
|
||||
两层:
|
||||
|
||||
- **底层 `RAGDocxParser`**(`docx_parser.py:9-123`):`python-docx`+`pandas` 读段落与表格;表格内容经 `__compose_table_content` 做"列类型推断"(日期 Dt / 数字 Nu / 中文人名 Nr / 英文 En 等 11 类正则),自动识别多行表头并把单元格拼成 `表头:值` 格式,保证表格在 chunk 中也能被关键词检索。
|
||||
- **上层 `Docx(RAGDocxParser)`**(`naive.py:105-323`):把段落里的图片用 `python-docx` 的 `xpath('.//pic:pic')` 抽出,挂到对应 paragraph;表格区域用 `__get_nearest_title` 上溯到 7 级标题构造层级路径作为 `<caption>Table Location: A > B > C</caption>`,这是检索时定位表格上下文的关键。
|
||||
- **超链接抽取**:`extract_links_from_docx` 遍历 `document.part.rels`,过滤 reltype 为 hyperlink 的关系,得到链接集合。`utils/file_utils.py:133-154`。
|
||||
- **`to_markdown`**:可选回退路径,使用 `mammoth.convert_to_html` + `markdownify`,图片嵌成 `data:` base64 URL。`naive.py:325-366`。
|
||||
- **NULL 关系修复**:上层 `Docx` 用 `load_from_xml_v2` monkey-patch 掉 `_SerializedRelationships.load_from_xml`,跳过 `../NULL` 与 `NULL` target 以绕过 python-docx#1105 已知 bug。`naive.py:493-506, 569`。
|
||||
|
||||
### 5.4 Excel/CSV 解析(`deepdoc/parser/excel_parser.py`)
|
||||
|
||||
- **多引擎容错**:`_load_excel_to_workbook` 先看魔数:`PK\x03\x04`(OOXML)或 `\xd0\xcf\x11\xe0`(OLE2)。openpyxl 失败回退 `pandas.read_excel`,再失败回退 `engine="calamine"`;非 Excel 头则当 CSV 处理(`pd.read_csv(on_bad_lines='skip')` 容忍坏行)。`excel_parser.py:18-53`。
|
||||
- **非法字符清洗**:`ILLEGAL_CHARACTERS_RE = re.compile(r"[\000-\010]|[\013-\014]|[\016-\037]")`,`_clean_dataframe` 把所有字符串单元格里的控制字符替换成空格,避免写入 Workbook 报错。`excel_parser.py:13, 56-62`。
|
||||
- **三种输出形态**:
|
||||
- `__call__()`:每行 → `表头1:值1\n表头2:值2\n...\n——SheetName`,作为一个 section(一个 chunk)。`excel_parser.py:203-246`。
|
||||
- `html()`:每 256 行打包成一张 `<table>`,header 复用,便于检索时整块召回。`excel_parser.py:144-187`。
|
||||
- `markdown()`:`df.to_markdown(index=False)`,整个表一段。
|
||||
- **图片抽取**:`_extract_images_from_worksheet` 通过 `ws._images` 的 anchor.row/col 还原图片位置,输出 `single_cell` / `multi_cell` span_type 元数据。`excel_parser.py:98-142`。
|
||||
- **重要:Excel 不走 `naive_merge`**:`naive.py:678-680` 显式注释"Excel 每行直接作为一个 chunk,不经过 naive_merge 避免被 delimiter 拆分"——直接 `tokenize_chunks(chunks, ...)`。
|
||||
|
||||
### 5.5 Markdown 解析(`deepdoc/parser/markdown_parser.py`)
|
||||
|
||||
- **表格抽取**:`extract_tables_and_remainder` 用三个正则按顺序剥离:标准 GFM 边框表格 → 无边框表格 → HTML `<table>...</table>`(含 `<html><body>` 包装),每张表单独成一个 chunk,剩余正文继续走 element 抽取。`markdown_parser.py:10-106`。
|
||||
- **元素抽取**:`MarkdownElementExtractor.extract_elements(delimiter)` 按行扫描,识别 `header(#~######)` / `code_block(```)` / `list_block(-/*/+/数字.)` / `blockquote(>)` / `text_block`,每种元素用对应私有方法收集起止行号。`markdown_parser.py:109-277`。
|
||||
- **图片嵌入**:当传入 `vision_model` 时,naive.py 会对每个 section 调 `markdown_parser.get_pictures()`(HTTP 下载或本地路径打开),把图片合并 `concat_img` 后丢给 `VisionFigureParser` 让 LLM 描述图片,描述文本拼回 section 末尾。`naive.py:697-709`。
|
||||
- **超链接深挖**:`get_hyperlink_urls(soup)` + `analyze_hyperlink=True` 触发递归 chunk。`naive.py:716-720`。
|
||||
|
||||
### 5.6 HTML 解析(`deepdoc/parser/html_parser.py`)
|
||||
|
||||
- **预清洗**:BeautifulSoup html5lib,移除 `<style>/<script>`,剥离 inline `style` 属性与 HTML 注释。`html_parser.py:39-52`。
|
||||
- **递归读文本**:`read_text_recursively` 给每个 BLOCK_TAG(h1-h6/p/div/article/section/aside/ul/ol/li/table/pre/code/blockquote/figure/figcaption)分配 `block_id` UUID,把 NavigableString 收集到所属 block。`<table>` 整段保留,单独给 `table_id` 元数据。`html_parser.py:89-131`。
|
||||
- **标题前缀化**:`merge_block_text` 在拼接时把 `h1-h6` 改写为 `# ~ ######`(Markdown 风格),保留层级语义到下游。`html_parser.py:134-161`。
|
||||
- **二次切分**:`chunk_block(block_txt_list, chunk_token_num=512)` 按 `chunk_token_num`(默认 512)合并 block,超长 block 用 `rag_tokenizer.tokenize()` 切成等长片段。`html_parser.py:163-196`。
|
||||
|
||||
### 5.7 JSON 解析(`deepdoc/parser/json_parser.py`)
|
||||
|
||||
- **结构感知切分**:`_json_split` 递归遍历 dict,按 `_json_size`(即 `json.dumps(...)` 的字符长度,乘以 2 作为 max_chunk_size)累计;超过 max 但当前 chunk ≥ min(`max - 200`)时开新 chunk,否则继续递归到子节点。**关键设计**:list 通过 `_list_to_dict_preprocessing` 转成索引化 dict,让数组也能按结构切分。`json_parser.py:46-95`。
|
||||
- **JSONL 自动检测**:`is_jsonl_format` 抽样前 10 行,若 ≥ 80% 行单独 `json.loads` 成功且整体不能 parse 为单个 JSON,则按 JSONL 处理。`json_parser.py:134-152`。
|
||||
|
||||
### 5.8 TXT/代码 解析(`deepdoc/parser/txt_parser.py`)
|
||||
|
||||
- 简单版:`get_text` 读全文(`find_codec` 嗅探编码),按 `delimiter="\n!?;。;!?"` 切分,**就地累加 token**:当前 chunk 超 `chunk_token_num` 才开新 chunk。`txt_parser.py:8-48`。
|
||||
- 适配的扩展名集:`.txt|.py|.js|.java|.c|.cpp|.h|.php|.go|.ts|.sh|.cs|.kt|.sql`,`naive.py:685`。
|
||||
|
||||
### 5.9 图片/音视频(`app/picture.py` / `app/audio.py`)
|
||||
|
||||
- 图片:`from app.core.rag.app.picture import chunk` → `picture_vision_llm_chunk(binary, vision_model, prompt, callback)`,多模态 LLM 直接产文。
|
||||
- 音视频:`from app.core.rag.app.audio import chunk` → 调 `seq2txt_mdl`(`QWenSeq2txt` 即 `qwen3-omni-flash`)做语音转文字。
|
||||
- PDF 也可以走 VisionParser 让 LLM 整页"看图说话",是 OCR 失败/扫描件的兜底。
|
||||
|
||||
### 5.10 PPT 与 .doc:外部依赖
|
||||
|
||||
- **PPTX/PPT** → `naive.py:628-651`:调 `async_convert_to_pdf`(`utils/libre_office.py:59-62`)把文件转 PDF,再递归 `chunk(dest_pdf_path, ...)`。
|
||||
- LibreOffice 路径硬编码 `/usr/bin/soffice`(Linux)或 `/Applications/LibreOffice.app/Contents/MacOS/soffice`(macOS),都不存在则抛 `HTTP 500`;`subprocess.run` 设 `timeout=120s` 防卡死。`utils/libre_office.py:11-57`。
|
||||
- 用 `ThreadPoolExecutor(max_workers=os.cpu_count()*2)` 提交异步转换任务;同进程多请求共享线程池。
|
||||
- **DOC(旧版二进制)** → `naive.py:738-761`:使用 Apache Tika(`tika-server.jar` JVM 进程,端口 9998)。环境必须有 Java 11+;初始化 `tika.initVM()` 后 `tika_parser.from_file(filename)['content']` 按 `\n` 切分。
|
||||
|
||||
### 5.11 视觉子系统(`deepdoc/vision/`)
|
||||
|
||||
- **OCR**:`OCR.__call__(img, device_id, cls)` 内部跑 `TextDetector` 检测文字框 → `TextRecognizer` 识别字符 → 可选方向分类。`vision/ocr.py:522, 694`。模型走 ONNX。
|
||||
- **LayoutRecognizer4YOLOv10**:YOLOv10 ONNX 模型,10 类 label,在 `__call__(image_list, ocr_res, scale_factor=3, thr=0.2, batch_size=16, drop=True)` 中接收图像与 OCR 结果,输出每个文字框的 layout 类型并把 `header/footer` 等 drop 掉。
|
||||
- **TableStructureRecognizer**:检测表格单元格的列、行、列头、合并单元格等 5 类。
|
||||
- **VisionFigureParser**(`figure_parser.py:52-118`):用 `ThreadPoolExecutor(10)` 并发把每张图片喂给 `vision_model`,超时 30s(`@timeout(30, 3)` 装饰器表示 30s 超时、3 次重试)。`vision_llm_figure_describe_prompt()` 给出统一的"详细描述这张图"指令。
|
||||
|
||||
## 6. Chunking 章节
|
||||
|
||||
### 6.1 Token 计数(`common/token_utils.py`)
|
||||
|
||||
- 模型固定为 `tiktoken.cl100k_base`(GPT-4 / text-embedding-ada-002 同口径),缓存目录 `res/`。`token_utils.py:6-9`。
|
||||
- `num_tokens_from_string(s)` 容错:`encode` 失败返回 0(不会让上层报错)。`token_utils.py:12-18`。
|
||||
- `truncate(s, max_len)` 按 token 截断,保护 LLM 上下文。`token_utils.py:56-58`。
|
||||
|
||||
### 6.2 编码嗅探(`nlp/__init__.py:37-55`)
|
||||
|
||||
- `find_codec(blob)`:先 `chardet.detect(blob[:1024])` 置信度 > 0.5 用结果("ascii" 强制升级到 "utf-8",避开 chardet 经典误判);置信度低则按预设 80+ 编码顺序列表逐个 `decode` 尝试,全失败 fallback `utf-8`。
|
||||
|
||||
### 6.3 主切分函数 `naive_merge`(`nlp/__init__.py:562-606`)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/__init__.py:562-606(核心算法)
|
||||
def naive_merge(sections, chunk_token_num=128, delimiter="\n。;!?", overlapped_percent=0):
|
||||
if isinstance(sections, str): sections = [sections]
|
||||
if isinstance(sections[0], str): sections = [(s, "") for s in sections]
|
||||
cks, tk_nums = [""], [0]
|
||||
def add_chunk(t, pos):
|
||||
nonlocal cks, tk_nums
|
||||
tnum = num_tokens_from_string(t)
|
||||
if tnum < 8: pos = "" # 太短不挂位置
|
||||
if cks[-1] == "" or tk_nums[-1] > chunk_token_num * (100 - overlapped_percent)/100.:
|
||||
# 开新 chunk,按 overlapped_percent 从上一块尾部留滑窗
|
||||
overlapped = RAGPdfParser.remove_tag(cks[-1])
|
||||
t = overlapped[int(len(overlapped)*(100-overlapped_percent)/100.):] + t
|
||||
if t.find(pos) < 0: t += pos
|
||||
cks.append(t); tk_nums.append(tnum)
|
||||
else:
|
||||
if cks[-1].find(pos) < 0: t += pos
|
||||
cks[-1] += t; tk_nums[-1] += tnum
|
||||
dels = get_delimiters(delimiter)
|
||||
for sec, pos in sections:
|
||||
if num_tokens_from_string(sec) < chunk_token_num:
|
||||
add_chunk("\n"+sec, pos); continue
|
||||
for sub_sec in re.split(r"(%s)" % dels, sec, flags=re.DOTALL):
|
||||
if re.match(f"^{dels}$", sub_sec): continue
|
||||
add_chunk("\n"+sub_sec, pos)
|
||||
return cks
|
||||
```
|
||||
|
||||
要点:
|
||||
- **token 上限**:当 `tk_nums[-1] > chunk_token_num * (1 - overlapped_percent/100)` 时开新 chunk。这意味着 `overlapped_percent=0` → 严格不超;`>0` → 提前开新块以预留滑窗空间。
|
||||
- **滑动窗口**:开新 chunk 时把上一块尾部 `overlapped_percent%` 的字符(**不是 token**)拼到新块开头;用 `RAGPdfParser.remove_tag` 先剥离位置标签,避免位置 tag 漏到新块。
|
||||
- **delimiter**:默认 `"\n。;!?"`,可被 `parser_config.delimiter` 覆盖。`get_delimiters` 支持反引号包围的多字符分隔符(如 `` `\n\n` ``),并按长度降序优先匹配(避免短符号"吞掉"长符号的左边界)。`nlp/__init__.py:760-776`。
|
||||
- **位置 tag 注入**:每段 `pos` 串只在 chunk 内不存在时才追加,避免重复(PDF chunk 一段往往跨多页,位置 tag 自然多次出现)。
|
||||
- **长 section 二次拆分**:单段 token 数 ≥ chunk_token_num 才用 delimiter 切,否则整段加入。
|
||||
|
||||
### 6.4 带图变体
|
||||
|
||||
- **`naive_merge_docx`**(`nlp/__init__.py:706-752`):sections 是 `[(text, image), ...]`;无图段先累积成行 line,遇到带图段才触发切分;同一 chunk 内多图用 `concat_img` 上下拼接成一张大图。**没有 overlapped_percent**。
|
||||
- **`naive_merge_with_images`**(`nlp/__init__.py:609-662`):与 `naive_merge` 同构,但同步把每段对应的 image 累积到 `result_images` 数组(多图也走 `concat_img` 合并)。
|
||||
|
||||
### 6.5 标题树切分(结构感知)
|
||||
|
||||
- **`hierarchical_merge(bull, sections, depth)`**(`nlp/__init__.py:471-559`):用 `BULLET_PATTERN[bull]`(5 套样式:第一/二/三章节系列、英文 PART/Chapter、Markdown # 系列)匹配标题,按层级建组,每组内累计 token 不超过 218 就合并到一个 chunk。是 manual.py / paper.py 等"标准化文档"app 用的策略。
|
||||
- **`tree_merge(bull, sections, depth)`**(`nlp/__init__.py:423-469`):同样基于 BULLET_PATTERN,但建一棵 `Node` 标题树,深度优先生成 chunk,让父级标题路径自动出现在每个 chunk 头部(`title1\ntitle2\nbody`)。
|
||||
- 这两个函数 **不在 `app/naive.py` 主链路**调用——naive.py 用的是 `naive_merge` 系列;它们服务于 `app/manual.py`、`app/paper.py`、`app/laws.py`、`app/book.py` 等专业 app。
|
||||
|
||||
### 6.6 关键词处理(`tokenize` / `tokenize_chunks` / `tokenize_table`)
|
||||
|
||||
最终交给 ES 的不是裸文本 chunk,而是带"分词字段"的 doc:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/__init__.py:251-256
|
||||
def tokenize(d, t, eng):
|
||||
d["content_with_weight"] = t
|
||||
t = re.sub(r"</?(table|td|caption|tr|th)( [^<>]{0,12})?>", " ", t)
|
||||
d["content_ltks"] = rag_tokenizer.tokenize(t) # 粗粒度分词
|
||||
d["content_sm_ltks"] = rag_tokenizer.fine_grained_tokenize(d["content_ltks"]) # 细粒度
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/__init__.py:258-277(tokenize_chunks)
|
||||
for ii, ck in enumerate(chunks):
|
||||
d = copy.deepcopy(doc) # doc 含 docnm_kwd / title_tks / title_sm_tks
|
||||
if pdf_parser: # 仅 PDF 链路
|
||||
d["image"], poss = pdf_parser.crop(ck, need_position=True)
|
||||
add_positions(d, poss)
|
||||
ck = pdf_parser.remove_tag(ck)
|
||||
else:
|
||||
add_positions(d, [[ii]*5]) # 无位置时填占位
|
||||
tokenize(d, ck, eng)
|
||||
res.append(d)
|
||||
```
|
||||
|
||||
- `add_positions(d, poss)` 写入 `page_num_int / position_int / top_int` 三列(`int` 后缀是 ES 的 type hint)。`nlp/__init__.py:325-337`。
|
||||
- `tokenize_table(tbls, doc, eng, batch_size=10)` 每 10 行表格组装成一个 chunk,挂图(如有)时 `doc_type_kwd="image"`。`nlp/__init__.py:295-322`。
|
||||
|
||||
### 6.7 `Chunk` Pydantic 模型(`models/chunk.py`)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/models/chunk.py
|
||||
class ChildDocumentChunk(BaseModel):
|
||||
page_content: str
|
||||
vector: list[float] | None = None
|
||||
metadata: dict = Field(default_factory=dict)
|
||||
|
||||
class DocumentChunk(BaseModel): # 父子结构
|
||||
page_content: str
|
||||
vector: list[float] | None = None
|
||||
metadata: dict = Field(default_factory=dict)
|
||||
children: list[ChildDocumentChunk] | None = None
|
||||
|
||||
class GeneralStructureChunk(BaseModel):
|
||||
general_chunks: list[str]
|
||||
|
||||
class ParentChildChunk(BaseModel):
|
||||
parent_content: str
|
||||
child_contents: list[str]
|
||||
|
||||
class ParentChildStructureChunk(BaseModel):
|
||||
parent_child_chunks: list[ParentChildChunk]
|
||||
parent_mode: str = "paragraph" # 父分段模式
|
||||
|
||||
class QAChunk(BaseModel):
|
||||
question: str
|
||||
answer: str
|
||||
|
||||
class QAStructureChunk(BaseModel):
|
||||
qa_chunks: list[QAChunk]
|
||||
```
|
||||
|
||||
> **重要:`DocumentChunk` 是上层服务(`services/`、`controllers/chunk_controller.py`)使用的"业务 schema",与 `tokenize_chunks` 输出的 ES doc 字段不同。** ES doc 实际字段(来自 `nlp/__init__.py` 注入):
|
||||
> - `docnm_kwd`:原文件名(keyword)
|
||||
> - `title_tks` / `title_sm_tks`:标题分词(粗 + 细)
|
||||
> - `content_with_weight`:原始 chunk 文本(用于 BM25 加权)
|
||||
> - `content_ltks` / `content_sm_ltks`:内容分词(粗 + 细)
|
||||
> - `page_num_int` / `position_int` / `top_int`:页码与坐标(用于 PDF 还原图片)
|
||||
> - `image`:PIL.Image,存为二进制
|
||||
> - `doc_type_kwd`:doc 类型("image" / 默认空)
|
||||
> - 后续 Embedding 阶段补 `q_vec_<dim>`(向量字段,详见 [S2-T2])。

|
||||
| `analyze_hyperlink` | `True` | 是否递归抓 docx/pdf 内超链接 | 显著拉长解析时间 |

|
||||
|
||||
### 8.2 环境变量
|
||||
|
||||
| 变量 | 默认 | 用途 |
|
||||
|---|---|---|
|
||||
| `LAYOUT_RECOGNIZER_TYPE` | `onnx` | `onnx` / `ascend` 切换 NPU |
|
||||
| `HF_ENDPOINT` | — | `https://hf-mirror.com` 加速国内 HF 拉取 |
|
||||
| `MINERU_EXECUTABLE` | `mineru` | MinerU CLI 路径 |
|
||||
| `MINERU_APISERVER` | `http://host.docker.internal:9987` | MinerU HTTP API |

||||
|
||||
### 8.3 调用入参(`chunk()` 形参)
|
||||
|
||||
| 参数 | 含义 |
|
||||
|---|---|
|
||||
| `filename` / `binary` | 文件路径或二进制内容(推荐 binary,path 模式不支持嵌入抽取) |
|
||||
| `from_page` / `to_page` | PDF 分页范围(节省内存) |
|
||||
| `lang` | `"Chinese"` / `"english"`(影响 `is_english` 与表格分隔符) |
|
||||
| `vision_model` | 多模态 LLM 实例(图片描述、VisionParser、音视频)|
|
||||
| `pdf_cls` | 自定义 PDF 类,继承 `Pdf`(可重写 OCR/layout 钩子) |
|
||||
| `is_root` | 内部递归标志,外部勿设 |
|
||||
| `section_only` | 仅返回切分文本,不做 ES doc 包装(用于增量调试) |
|
||||
|
||||
## 9. 边界条件与已知限制
|
||||
|
||||
1. **PPT/DOC 强依赖外部组件**:LibreOffice 与 Apache Tika 任一缺失都会让对应格式直接 500,**没有内建兜底**。建议生产容器固化版本。
|
||||
2. **`extract_embed_file` 不支持 path 模式**:仅接受 `bytes`,root 调用必须传 `binary` 否则抛 `Exception`(`naive.py:541`)。
|
||||
3. **HF 模型懒加载**:首次启动会从 HuggingFace 拉 `text_concat_xgb_v1.0` 与 OCR/layout/TSR 模型(共数百 MB),冷启动慢;建议 image build 阶段预热。
|
||||
4. **同进程 PDF 锁**:`LOCK_KEY_pdfplumber` 全局 lock 串行化 `pdfplumber.open()`,**单进程内 PDF 解析无法真并发**;需要并发则起多进程或多容器。
|
||||
5. **`naive_merge` 滑窗按字符不按 token**:`overlapped_percent=20` 实际重叠是上一块字符串末尾 20% 字符,token 数会有偏差(中文字符占 1-3 token 不等)。
|
||||
6. **图片 chunk 无 `position_int`**:`tokenize_chunks_with_images` 只填了 `[ii]*5`(占位),不能像 PDF chunk 那样在原图上还原坐标。
|
||||
7. **`naive_merge_docx` 没有 `overlapped_percent`**:docx 链路无重叠窗口(实现上漏掉了),如需重叠暂时只能改代码或者把 docx → markdown 再走 markdown 链路。
|
||||
8. **JSONL 检测启发式**:`is_jsonl_format` 只看前 10 行 80% 阈值,对"前几行恰好都是合法单行 JSON 但整体也是合法 JSON 数组"的边界情况会误判。
|
||||
9. **Crawler 不支持 SPA**:`is_static_content` 直接拒绝 `<200 chars body + >5 scripts` 的页面,没有 Playwright/Puppeteer 渲染兜底。
|
||||
10. **飞书在线文档导出超时**:`_export_file` 写死 `max_retries=10, poll_interval=2s`(即 20s 上限),大文档可能超时 → `FeishuAPIError("Export task did not complete...")`。
|
||||
|
||||
## 10. 监控指标与排错指引
|
||||
|
||||
### 10.1 关键日志锚点(按 timer 输出)
|
||||
|
||||
- `__images__ dedupe_chars cost {t}s`(PDF 字符抽取)
|
||||
- `__images__ {N} pages cost {t}s`(OCR 总耗时)
|
||||
- `naive_merge({filename}): {t}`(chunking 耗时)
|
||||
- `OCR finished` / `Layout analysis` / `Table analysis` / `Text merged`(callback 进度)
|
||||
|
||||
### 10.2 常见 Bug & 定位
|
||||
|
||||
| 现象 | 可能原因 | 定位 |
|
||||
|---|---|---|
|
||||
| 中文 chunk 出现乱码 | 文件编码非 UTF-8 但 `find_codec` 误判 | 在 `find_codec` 入口打日志看 `chardet.detect` 返回 |
|
||||
| Excel 单元格丢失 | `ILLEGAL_CHARACTERS_RE` 把控制字符替换成空格 | `_clean_dataframe` 是不是把业务字符当成非法字符了 |
|
||||
| PDF 图被截到一半 | `crop()` 计算 bottom 时跨页页高累积出错 | `pdf_parser.py:1245-1260` 检查 `page_cum_height` |
|
||||
| 飞书 token 频繁刷新 | `TTLCache(ttl=7200-300)` 只缓存 1 token,多并发实例每个进程独立缓存 | 接 Redis 共享缓存 |
|
||||
| MinerU 报"not found" | `MINERU_EXECUTABLE` PATH 不对 | `mineru_parser.py:check_installation` 打 trace |

## 11. 优化建议与未来扩展点
|
||||
|
||||
### 11.1 架构改造建议(即刻收益)
|
||||
|
||||
1. **Loader 抽象层**:把 `WebCrawler` / `FeishuAPIClient` / `YuqueAPIClient` 统一收敛为 `BaseLoader.load() -> Iterable[LoadedDocument]` 接口,下游统一消费 `LoadedDocument(filename, binary, source_metadata)`。这样 confluence/Notion/SharePoint 接入只需新写一个 Loader,不用改 `naive.py`。
|
||||
2. **Parser 注册表外露**:`PARSERS = {...}` 当前只覆盖 PDF;建议扩到 `FORMAT_PARSERS = {".docx": Docx, ".xlsx": ExcelParser, ...}`,把 `chunk()` 里的大 if-elif 链替换成 dict 查表 + 插件机制。新格式(如 epub/odt)通过 `register_parser(".epub", EpubParser)` 注入。
|
||||
3. **Chunking 策略策略化**:把 `naive_merge / naive_merge_docx / naive_merge_with_images / hierarchical_merge / tree_merge` 实现 `BaseChunker` 接口(`chunk(sections) -> List[Chunk]`),由 `parser_config.chunking_strategy` 选择。当前 docx 缺 `overlapped_percent` 这种"碎片化丢失"会自然消失。
|
||||
4. **Token 切分而非字符切分**:`naive_merge` 的滑窗用 `encoder.encode(text)[-N:]` 反解 token-level overlap,避免中文字符≠token 的口径错配。
|
||||
5. **共享 token 缓存**:飞书/语雀 token 改为 Redis 共享,目前每实例一份的 TTLCache 在 K8s 多副本下会触发限流。
|
||||
6. **嵌入文件深度限制**:`extract_embed_file` 是"only first layer",但调用方递归 `chunk(...is_root=False)` 没有 depth guard,恶意文件可造成栈深递归 → 加 `max_depth=3`。
|
||||
7. **PDF 解析进程化**:`pdfplumber` 全局锁实质单线程,对 PDF 重负载场景把 `Pdf` 包成独立 worker(multiprocessing 或 ProcessPoolExecutor),让 OCR/layout 跨核并行。
|
||||
|
||||
### 11.2 功能扩展方向
|
||||
|
||||
1. **多模态深整合**:现在 `VisionParser` / `picture_vision_llm_chunk` / `VisionFigureParser` 都是"图 → 描述文本 → 文本 chunk"的有损转换;可以保留 image embedding 与 text embedding 并存,下游做多模态混合检索(CLIP/SigLIP 与文本向量并列召回)。
|
||||
2. **语义切分(Semantic Chunking)**:按嵌入相似度(如 `cosine(emb_i, emb_{i+1}) < 0.7` 作为切点)替代固定 token 切分,实验证明可显著提升长文档召回。`naive_merge` 已经有插槽,加一个 `chunking_strategy="semantic"` 即可。
|
||||
3. **结构化字段抽取**:现在表格只做行→自然语言转换("列名:值"),没有把表格存成结构化 JSON。可在 `tokenize_table` 旁路输出 `table_data: dict`,配合 [S2-T3] 的混合搜索,用关键词字段精确过滤。
|
||||
4. **缓存命中**:相同文件的解析结果(按 sha256 + parser_config hash)应进缓存,重新入库时跳过 OCR;`extract_embed_file` 已有 `_sha10` 雏形,可扩为完整 cache key。
|
||||
5. **流式 chunk 输出**:当前 `chunk()` 返回 `List`,大文件全量加载到内存;改为 `Iterable[Chunk]` + 生产者-消费者,可以让 Embedding 与 OCR 并行流水线。
|
||||
6. **更细粒度的进度上报**:`callback(prog, msg)` 现在是粗粒度(0.1/0.6/0.8…),生产中需要展示"第几页/共多少页",建议结构化为 `callback({stage, current, total, msg})`。
|
||||
7. **Crawler 增量化**:当前每次全量 crawl,没有 ETag/If-Modified-Since 机制;接 `last_crawl_timestamp` 让二次抓取只拉变化页。
|
||||
|
||||
### 11.3 与下游约定(输出契约)
|
||||
|
||||
本文档负责输出的 chunk 序列应包含至少:
|
||||
|
||||
```python
|
||||
{
|
||||
"docnm_kwd": str, # 文件名
|
||||
"title_tks": str, # 文档标题分词(粗)
|
||||
"title_sm_tks": str, # 文档标题分词(细)
|
||||
"content_with_weight": str, # 原始 chunk 文本(必填)
|
||||
"content_ltks": str, # 内容分词(粗)
|
||||
"content_sm_ltks": str, # 内容分词(细)
|
||||
"page_num_int": list[int], # 页码(PDF 才有意义)
|
||||
"position_int": list[tuple], # (page, x0, x1, top, bottom)
|
||||
"top_int": list[int], # 行顶 y 坐标
|
||||
"image": Optional[PIL.Image], # PDF/Excel 才有
|
||||
"doc_type_kwd": Optional[str], # "image" 或空
|
||||
}
|
||||
```
|
||||
|
||||
[S2-T3] 索引结构应消费上述字段(参考 vdb/elasticsearch/elasticsearch_vector.py 的 mapping)。[S2-T2] Embedding 应在此基础上补 `q_<dim>_vec` 列。[S2-T6] 端到端调用链路从 `app/naive.py:chunk()` 开始追踪。

# [S2-T2] Embedding 模型选择与向量生成实现详解
|
||||
|
||||
---
|
||||
|
||||
## 一句话定位
|
||||
|
||||
MemoryBear 的 Embedding 层负责将文本 Chunk 转化为稠密向量,是连接"非结构化文本"与"向量数据库"的核心桥梁。当前系统同时存在两条 Embedding 调用路径:**基于 LangChain 的统一封装层(RedBearEmbeddings,面向 ES 向量库)** 与 **遗留的原始实现层(embedding_model.py,面向 GraphRAG 与 Dealer 检索)**。
|
||||
|
||||
---
|
||||
|
||||
## 设计目标与适用场景
|
||||
|
||||
- **多提供商兼容**:覆盖 OpenAI、Azure、DashScope(通义千问)、Volcano(火山引擎)、Xinference、GPUStack、Ollama、Bedrock 等主流 Embedding 服务
|
||||
- **多模态扩展**:火山引擎支持文本/图片/视频多模态 Embedding
|
||||
- **知识库隔离**:每个知识库独立配置 Embedding 模型,通过 `knowledge.embedding_id` 关联
|
||||
- **GraphRAG 支撑**:为实体/关系节点生成向量,用于图检索中的语义匹配

|
||||
| `LocalAIEmbed` | LocalAI | 用户指定 | 8000 tokens | 同上 | 16 | LocalAI / LMStudio |
|
||||
|
||||
### 1.2 统一封装层支持的模型(RedBearEmbeddings)
|
||||
|
||||
| Provider | 对应的 LangChain 类 | 默认超时 | 默认重试 | 多模态支持 |
|
||||
|----------|-------------------|---------|---------|-----------|
|
||||
| `openai` | `langchain_openai.OpenAIEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `xinference` | `langchain_openai.OpenAIEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `gpustack` | `langchain_openai.OpenAIEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `dashscope` | `langchain_community.DashScopeEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `ollama` | `langchain_ollama.OllamaEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `bedrock` | `langchain_aws.BedrockEmbeddings` | 120s | 2 次 | 否 |
|
||||
| `volcano` | `volcenginesdkarkruntime.Ark` (原生 SDK) | 120s | 2 次 | **是**(文本/图片/视频) |
|
||||
|
||||
### 1.3 默认模型
|
||||
|
||||
- **知识库默认 Embedding**:通过 `workspace.embedding` 继承,或管理员在创建知识库时手动指定 `embedding_id`
|
||||
- **数据库关联**:`knowledge.embedding_id` → `model_configs.id`(ModelConfig 表)→ `model_api_keys`(API Key 表)
|
||||
- **无默认模型硬编码**:系统不内置默认模型名称,完全依赖数据库配置
|
||||
|
||||
### 1.4 切换方式
|
||||
|
||||
1. **管理后台配置**:在模型管理页面添加新的 Embedding 模型配置(provider + model_name + api_key + base_url)
|
||||
2. **知识库绑定**:创建/编辑知识库时选择新的 `embedding_id`
|
||||
3. **即时生效**:新写入的 Chunk 使用新模型;历史 Chunk 向量保持不变(见"维度变更兼容"章节)
|
||||

||||
|
||||
## 2. 调用链路详解
|
||||
|
||||
### 2.1 入库链路(Chunk → ES Vector)
|
||||
|
||||
```
|
||||
memory_konwledges_server.py:430
|
||||
vector_service.add_chunks([chunk])
|
||||
│
|
||||
▼
|
||||
elasticsearch_vector.py:55-63
|
||||
def add_chunks(self, chunks: list[DocumentChunk], **kwargs):
|
||||

|
||||
if self.is_multimodal_embedding:
|
||||
embeddings = self.embeddings.embed_batch(texts) # 火山引擎
|
||||
else:
|
||||
embeddings = self.embeddings.embed_documents(list(texts)) # 其他
|
||||
self.create(chunks, embeddings, **kwargs)
|
||||
│
|
||||
▼
|
||||
models/embedding.py:65-78
|
||||
def embed_documents(self, texts: list[str]) -> list[list[float]]:
|
||||
if self._is_volcano:
|
||||
# 多模态 Embedding
|
||||
contents = [{"type": "text", "text": text} for text in texts]
|
||||
response = self._client.multimodal_embeddings.create(...)
|
||||
return [response.data.embedding]
|
||||
else:
|
||||
return self._model.embed_documents(texts) # LangChain 标准接口
|
||||
```
|
||||
|
||||
### 2.2 检索链路(Query → Vector → ES Search)
|
||||
|
||||
```
|
||||
elasticsearch_vector.py:374-380
|
||||
def search_by_vector(self, query: str, **kwargs: Any) -> list[DocumentChunk]:
|
||||
if self.is_multimodal_embedding:
|
||||
query_vector = self.embeddings.embed_text(query) # 火山引擎
|
||||
else:
|
||||
query_vector = self.embeddings.embed_query(query) # 其他
|
||||
# ES script_score: cosineSimilarity(params.query_vector, 'vector') + 1.0
|
||||
```
|
||||
|
||||
### 2.3 GraphRAG 链路(Entity/Relation → Vector)
|
||||
|
||||
```
|
||||
graphrag/utils.py:301-327
|
||||
async def graph_node_to_chunk(kb_id, embd_mdl, ent_name, meta, chunks):
|
||||
ebd = get_embed_cache(embd_mdl.model_name, ent_name)
|
||||
if ebd is None:
|
||||
async with chat_limiter: # 并发限流
|
||||
with trio.fail_after(...):
|
||||
ebd, _ = await trio.to_thread.run_sync(
|
||||
lambda: embd_mdl.encode([ent_name])) # 遗留 OpenAIEmbed
|
||||
ebd = ebd[0]
|
||||
set_embed_cache(embd_mdl.model_name, ent_name, ebd) # Redis 缓存
|
||||
chunk["q_%d_vec" % len(ebd)] = ebd
|
||||
```
|
||||
|
||||
### 2.4 Dealer 检索链路(加权融合检索)
|
||||
|
||||
```
|
||||
nlp/search.py:365-373
|
||||
def get_vector(self, txt, emb_mdl, topk=10, similarity=0.1):
|
||||
qv, _ = emb_mdl.encode_queries(txt) # 遗留 OpenAIEmbed
|
||||
embedding_data = [get_float(v) for v in qv]
|
||||
vector_column_name = f"q_{len(embedding_data)}_vec"
|
||||
return MatchDenseExpr(vector_column_name, embedding_data, ...)
|
||||
```
|
||||
|
||||
### 2.5 同步/异步说明
|
||||
|
||||
| 场景 | 模式 | 说明 |
|
||||
|------|------|------|
|
||||
| ES 向量入库 | **同步** | `embed_documents()` 为同步调用,在请求线程中执行 |
|
||||
| ES 向量检索 | **同步** | `embed_query()` 为同步调用 |
|
||||
| GraphRAG 实体嵌入 | **异步** | `trio.to_thread.run_sync()` 将同步 Embedding 调用放入线程池 |
|
||||
| 模型验证 | **异步** | `asyncio.to_thread()` 包装同步调用 |
|
||||
|
||||
### 2.6 批量大小与并发控制
|
||||
|
||||
| 控制点 | 数值 | 位置 |
|
||||
|--------|------|------|
|
||||
| OpenAI 兼容类 batch_size | 16 | `embedding_model.py:52`, `:83`, `:178` |
|
||||
| QWen batch_size | 4 | `embedding_model.py:133` |
|
||||
| HuggingFace | 无批量(全量发送) | `embedding_model.py:258` |
|
||||
| GraphRAG 并发限流 | `MAX_CONCURRENT_CHATS`(默认 10) | `graphrag/utils.py:41` |
|
||||
| RedBearModelConfig 并发 | 5(配置项,当前未在 Embedding 中使用) | `models/base.py:37` |
|
||||
|
||||
---
|
||||
|
||||
## 3. 生产级关注点
|
||||
|
||||
### 3.1 限流与配额管理
|
||||
|
||||
**现状分析:**
|
||||
|
||||
- **无显式 API 速率限制**:代码中未发现针对 Embedding API 的 RPM/TPM 限流逻辑
|
||||
- **LangChain 内部限流**:`OpenAIEmbeddings` 内部有基础请求间隔控制,但不可配置
|
||||
- **并发控制仅存在于 GraphRAG**:`chat_limiter = trio.CapacityLimiter(10)` 限制 GraphRAG 中实体/关系嵌入的并发数
|
||||
|
||||
**源码引用:**
|
||||
|
||||
```python
|
||||
# graphrag/utils.py:41
|
||||
chat_limiter = trio.CapacityLimiter(int(os.environ.get("MAX_CONCURRENT_CHATS", 10)))
|
||||
|
||||
# graphrag/utils.py:320-322
|
||||
async with chat_limiter:
|
||||
with trio.fail_after(3 if enable_timeout_assertion else 30000000):
|
||||
ebd, _ = await trio.to_thread.run_sync(lambda: embd_mdl.encode([ent_name]))
|
||||
```
|
||||
|
||||
### 3.2 失败重试与降级
|
||||
|
||||
**现状分析:**
|
||||
|
||||
| 路径 | 重试机制 | 降级策略 |
|
||||
|------|---------|---------|
|
||||
| QWenEmbed(遗留) | 显式 5 次重试,间隔 10s | 抛出异常,无降级 |
|
||||
| RedBearEmbeddings(统一层) | `max_retries`(默认 2,由 LangChain SDK 内部实现) | 抛出异常,无降级 |
|
||||
| ES 连接 | `retry_on_timeout=True`, `max_retries=3` | 抛出 ConnectionError |
|
||||
| 知识检索 | 单库失败不影响其他库 | `continue` 跳过 |
|
||||
|
||||
**源码引用:**
|
||||
|
||||
```python
|
||||
# embedding_model.py:138-143(QWen 显式重试)
|
||||
retry_max = 5
|
||||
resp = dashscope.TextEmbedding.call(...)
|
||||
while (resp["output"] is None ...) and retry_max > 0:
|
||||
time.sleep(10)
|
||||
resp = dashscope.TextEmbedding.call(...)
|
||||
retry_max -= 1
|
||||
|
||||
# models/base.py:34-36(统一层重试配置)
|
||||
timeout: float = Field(default_factory=lambda: float(os.getenv("LLM_TIMEOUT", "120.0")))
|
||||
max_retries: int = Field(default_factory=lambda: int(os.getenv("LLM_MAX_RETRIES", "2")))
|
||||
```
|
||||
|
||||
**⚠️ 关键缺口:无备用模型降级机制。** 当主 Embedding 模型服务不可用时,系统会直接失败,不会自动切换备用模型。
|
||||
|
||||
### 3.3 缓存策略
|
||||
|
||||
**现状分析:**
|
||||
|
||||
- **GraphRAG 实体/关系缓存**:Redis 缓存,TTL 24 小时,key 为 `xxhash(model_name + text)`
|
||||
- **ES 向量入库/检索**:**无缓存**,每次调用都实时请求 Embedding API
|
||||
- **无全局 Embedding 缓存层**
|
||||
|
||||
**源码引用:**
|
||||
|
||||
```python
|
||||
# graphrag/utils.py:115-134
|
||||
redis_client = redis.StrictRedis(**redis_conn_params)
|
||||
|
||||
def get_embed_cache(llmnm, txt):
|
||||
hasher = xxhash.xxh64()
|
||||
hasher.update(str(llmnm).encode("utf-8"))
|
||||
hasher.update(str(txt).encode("utf-8"))
|
||||
k = hasher.hexdigest()
|
||||
bin = redis_client.get(k)
|
||||
if not bin:
|
||||
return
|
||||
return np.array(json.loads(bin))
|
||||
|
||||
def set_embed_cache(llmnm, txt, arr):
|
||||
# ... 设置 Redis,TTL = 24 * 3600
|
||||
```
|
||||
|
||||
**影响评估:**
|
||||
- 重复文本(如相同实体名)在 GraphRAG 中可命中缓存,节省 API 调用
|
||||
- 常规知识库检索/入库中,相同 Chunk 或 Query 重复向量化,造成冗余 API 开销
|
||||
|
||||
### 3.4 维度变更对历史向量的兼容
|
||||
|
||||
**现状分析:**
|
||||
|
||||
- **无自动兼容机制**:更换 Embedding 模型后,历史 Chunk 的向量维度不变,新 Chunk 使用新维度
|
||||
- **ES Mapping 冲突**:`create_collection()` 在创建索引时根据第一条向量的长度设置 `dense_vector.dims`,若后续向量维度不同会写入失败
|
||||
- **混合维度风险**:同一索引中既有 1536 维又有 768 维的向量,ES `dense_vector` 字段要求固定维度
|
||||
|
||||
**源码引用:**
|
||||
|
||||
```python
|
||||
# elasticsearch_vector.py:653-658
|
||||
Field.VECTOR.value: {
|
||||
"type": "dense_vector",
|
||||
"dims": len(embeddings[0]), # 根据第一条向量动态决定
|
||||
"index": True,
|
||||
"similarity": "cosine"
|
||||
}
|
||||
```
|
||||
|
||||
**推荐操作(如何安全替换 Embedding 模型):**
|
||||
|
||||
1. **创建新知识库**:为新知识库配置新的 Embedding 模型,避免影响已有数据
|
||||
2. **重建索引(谨慎)**:如需迁移历史数据,需:
|
||||
- 删除旧 ES 索引(`Vector_index_{knowledge_id}_Node`)
|
||||
- 重新解析所有文档(触发新的 Embedding 调用)
|
||||
- 确认所有 Chunk 使用同一模型生成向量
|
||||
3. **版本标记**:建议在知识库 metadata 中记录当前使用的 Embedding 模型版本,便于追踪
|
||||
|
||||
**影响面分析:**
|
||||
|
||||
| 操作 | 影响范围 | 风险等级 |
|
||||
|------|---------|---------|
|
||||
| 修改知识库 embedding_id | 仅新入库 Chunk | 低 |
|
||||
| 修改已有知识库 embedding_id + 不重建索引 | 检索时 Query 向量与 Chunk 向量维度不匹配 | **高** |
|
||||
| 重建索引 | 全量重新 Embedding,API 费用 + 时间成本 | 中 |

|
||||
|
||||
## 6. 如何替换 Embedding 模型(操作步骤 + 影响面分析)
|
||||
|
||||
### 6.1 操作步骤
|
||||
|
||||
**场景 A:为新知识库配置新模型(推荐,零风险)**
|
||||
|
||||
1. 进入管理后台 → 模型管理 → 添加新 Embedding 模型配置
|
||||
2. 填写 provider、model_name、api_key、base_url
|
||||
3. 验证模型可用性(model_service.py 会调用 `embed_documents` 测试)
|
||||
4. 创建新知识库时选择该模型作为 `embedding_id`
|
||||
5. 新入库文档自动使用新模型生成向量
|
||||
|
||||
**场景 B:替换已有知识库的 Embedding 模型(高风险,需重建索引)**
|
||||
|
||||
1. **备份数据**:导出知识库下所有文档元数据
|
||||
2. **删除旧 ES 索引**:
|
||||
```python
|
||||
# 索引名格式: Vector_index_{knowledge_id}_Node
|
||||
vector_service.delete() # elasticsearch_vector.py:176
|
||||
```
|
||||
3. **更新知识库配置**:修改 `knowledge.embedding_id` 为新模型 ID
|
||||
4. **重新解析所有文档**:触发完整的 Chunk → Embedding → ES 写入流程
|
||||
5. **验证维度一致性**:确认所有 Chunk 向量维度相同
|
||||
6. **检索验证**:执行测试查询,确认向量检索正常返回
|
||||
|
||||
### 6.2 影响面分析
|
||||
|
||||
| 组件 | 影响 | 说明 |
|
||||
|------|------|------|
|
||||
| ES 索引 | **必须重建** | `dense_vector.dims` 在创建时固定,不支持动态变更 |
|
||||
| 历史 Chunk | **需重新嵌入** | 旧向量与新向量维度/语义空间不同,不能混用 |
|
||||
| 检索质量 | 可能变化 | 不同模型的语义表示能力不同,需重新调参阈值 |
|
||||
| API 成本 | 短期增加 | 重建索引期间产生全量 Embedding API 调用费用 |
|
||||
| GraphRAG | 需同步更新 | 实体/关系向量也需使用同一模型,否则语义空间不一致 |
|
||||
| 混合检索 | 需重新校准 | 向量相似度权重 `vector_similarity_weight` 可能需要调整 |
|
||||
|
||||
---
|
||||
|
||||
## 7. 边界条件与已知限制
|
||||
|
||||
1. **维度上限**:ES `dense_vector` 字段 `index: True` 时维度上限 1024;`index: False` 时上限 2048。当前代码 `index: True`,若使用 1536 维模型(如 OpenAI text-embedding-ada-002)会触发此限制
|
||||
2. **batch_size 硬编码**:各模型的 batch_size(16 或 4)在源码中写死,不可配置
|
||||
3. **无 Embedding 调用计费统计**:系统未记录 Embedding API 的调用次数和 Token 消耗(仅 LLM 有统计)
|
||||
4. **无 Embedding 降级**:主模型失败时无自动切换到备用模型的机制
|
||||
5. **QWen 截断差异**:QWen 截断到 2048 tokens,而其他 OpenAI 兼容类截断到 8000,混合使用时需特别注意
|
||||
6. **文本截断使用 cl100k_base**:`token_utils.py` 使用 `cl100k_base` 编码器,可能与实际模型使用的 tokenizer 不一致(如 QWen 使用自己的 tokenizer),导致截断长度不准
|
||||

||||

|
||||
|
||||
## 8. 监控指标与排错指引
|
||||
|
||||
### 8.1 建议监控指标
|
||||
|
||||
| 指标 | 采集方式 | 告警阈值建议 |
|
||||
|------|---------|-------------|
|
||||
| Embedding API 响应时间 | LangChain callback 或中间件拦截 | P99 > 5s |
|
||||
| Embedding API 错误率 | 异常捕获统计 | > 1% |
|
||||
| Embedding Token 消耗 | API 响应中的 usage.total_tokens | 按预算设置 |
|
||||
| ES 向量写入延迟 | ES bulk API 响应时间 | > 2s |
|
||||
| Redis 缓存命中率 | `get_embed_cache` 命中统计 | < 50% 时排查 |
|
||||
|
||||
### 8.2 常见故障排查
|
||||
|
||||
| 现象 | 根因 | 排查路径 |
|
||||
|------|------|---------|
|
||||
| 向量检索返回空 | 维度不匹配 / 相似度阈值过高 | 检查 `dense_vector.dims` 与 Embedding 输出维度是否一致;降低 `score_threshold` |
|
||||
| Embedding 调用超时 | API 服务商响应慢 / 文本过长 | 检查 `LLM_TIMEOUT`;检查文本是否被正确截断 |
|
||||
| 批量 Embedding 失败 | batch_size 过大 | 减小 batch_size(需改源码) |
|
||||
| GraphRAG 实体向量不一致 | 缓存命中但模型已更换 | 清除 Redis 中 `get_embed_cache` 相关 key |
|
||||
| ES 写入报错 "illegal_argument_exception" | dense_vector 维度超限 | 确认 `index: True` 时 dims <= 1024 |
|
||||
|
||||
---
|
||||
|
||||
## 9. 优化建议与未来扩展点
|
||||
|
||||
### 9.1 短期优化(代码级)
|
||||
|
||||
1. **全局 Embedding 缓存层**:将 `get_embed_cache` / `set_embed_cache` 机制扩展到 ES 向量入库/检索链路,减少重复 API 调用
|
||||
2. **可配置 batch_size**:将硬编码的 16/4 提取为环境变量或数据库配置项
|
||||
3. **备用模型降级**:实现 Embedding 模型的主备切换逻辑(类似 LLM 的 fallback 机制)
|
||||
4. **维度一致性校验**:在 `add_chunks()` 和 `search_by_vector()` 中增加维度校验,提前发现不匹配问题
|
||||
|
||||
### 9.2 中期优化(架构级)
|
||||
|
||||
1. **Embedding 服务化**:将 Embedding 调用抽离为独立微服务,支持:
|
||||
- 统一缓存(Redis + 本地 LRU)
|
||||
- 请求队列 + 速率限制
|
||||
- 多模型负载均衡
|
||||
2. **异步 Embedding 流水线**:文档入库时先写入队列,后台异步完成 Embedding 和 ES 写入
|
||||
3. **Embedding 质量监控**:定期抽样检测向量空间的分布质量(如余弦相似度分布、异常值检测)
|
||||
|
||||
### 9.3 长期扩展(功能级)
|
||||
|
||||
1. **多模态 Embedding 全链路支持**:当前仅火山引擎支持多模态,未来可扩展到更多 provider
|
||||
2. **自适应维度选择**:根据知识库数据量和精度需求,自动推荐最优 Embedding 维度
|
||||
3. **Embedding 微调**:支持基于领域数据的 Embedding 模型微调(如 fine-tune BGE)
|
||||
4. **跨模型向量映射**:研究不同 Embedding 模型之间的向量映射技术,实现平滑迁移而不重建索引

# [S2-T3] 向量数据库选型、索引与检索策略实现详解
|
||||
|
||||
> 范围:`api/app/core/rag/vdb/elasticsearch/`、`api/app/core/rag/utils/es_conn.py`、`api/app/core/rag/utils/doc_store_conn.py`、`api/app/core/rag/nlp/{search.py, query.py}`、`api/app/core/rag/res/mapping.json` 以及调用方 `api/app/core/workflow/nodes/knowledge/node.py`、`api/app/services/memory_konwledges_server.py` 等。
|
||||
>
|
||||
> 提示:MemoryBear 当前版本中存在**两套并行的 ES 实现路径**,本文会逐一拆开说明,并给出二者的边界与实际调用方。
|
||||
|
||||
---
|
||||
|
||||
## 一、一句话定位
|
||||
|
||||
MemoryBear 使用 **Elasticsearch 8.x** 作为向量 + 全文一体化的检索引擎,通过 `dense_vector` (HNSW) 实现语义检索、Lucene + IK 分词器实现关键词检索,并在应用层与 ES DSL 层各自实现一套"混合搜索"策略(应用层为"双路 + 去重 + 可选 Rerank",DSL 层为"weighted_sum 加权融合")。
|
||||
|
||||
## 二、设计目标与选型说明
|
||||
|
||||
### 2.1 选型动机(为什么是 Elasticsearch 而非 Milvus / Qdrant / Pinecone?)
|
||||
|
||||
README 中明确把 **"Hybrid Search: Keyword + Semantic Vector"** 列为产品级核心能力之一(README.md:62-66)。结合源码可以推出三条关键决策依据:
|
||||
|
||||
1. **关键词侧需要 Lucene 生态** — 既要中文分词(IK `ik_max_word`),又要 BM25 / 布尔过滤 / 高亮 / 同义词扩展 / 短语匹配 / 字段权重等成熟能力,Milvus / Qdrant / Pinecone 在这一侧几乎都需要外接 ES/OS。`api/app/core/rag/nlp/query.py:14-22` 的 `query_fields = ["title_tks^10", "important_kwd^30", "content_ltks^2", ...]` 就是典型 Lucene field-boost 写法,离开 ES 改造代价很高。
|
||||
2. **一份索引同时承担多种载荷** — 一个 ES 索引同时存储 chunk 文本 (`page_content`)、向量 (`*_vec`)、稀疏 tokens (`*_tks` / `*_ltks`)、标签 rank_features (`tag_feas`)、PageRank-like 分数 (`pagerank_fea`)、地理 (`lat_lon`)、嵌套结构 (`*_nst`) 等异构字段(见 `api/app/core/rag/res/mapping.json:25-209`)。专用向量库无法承载这种混合 schema。
|
||||
3. **运维与生态成本** — 团队仅运行 PostgreSQL / Neo4j / Redis / ES(README "Prerequisites"),引入第二套向量服务会显著抬高运维曲线。`@singleton` 的 `ESConnection` (`api/app/core/rag/utils/es_conn.py:26-56`) 与 `ElasticSearchVectorFactory._client` (`api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:666-732`) 共享连接,工程上已经按"单实例多用途"在使用 ES。
|
||||
|
||||
> 代价:ES 的 ANN 在百万-千万 chunk 时延迟会明显高于 Milvus/Qdrant;当未来 chunk 量级或 QPS 显著增长时,本架构需要拆出独立向量服务(详见 §6 优化建议)。
|
||||
|
||||
### 2.2 ES 版本约束
|
||||
|
||||
启动期硬性校验 ES 必须 ≥ 8.0:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:44-49
|
||||
v = self.info.get("version", {"number": "8.0.0"})
|
||||
v = v["number"].split(".")[0]
|
||||
if int(v) < 8:
|
||||
msg = f"Elasticsearch version must be greater than or equal to 8, current version: {v}"
|
||||
logger.error(msg)
|
||||
raise Exception(msg)
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:716-722
|
||||
if not cls._version_checked:
|
||||
info = client.info()
|
||||
version = info["version"]["number"]
|
||||
if parse_version(version) < parse_version("8.0.0"):
|
||||
raise ValueError(f"Elasticsearch version must be >= 8.0.0, got {version}")
|
||||
```
|
||||
|
||||
> **why**:ES 8.0 才正式提供 `dense_vector` HNSW 索引、`knn` 顶层查询、以及 query_string + knn 的混合检索,本系统的 `s.knn(...)`、`type=dense_vector index=true similarity=cosine` 都依赖该版本。
|
||||
|
||||

- 抽象基类:`api/app/core/rag/utils/doc_store_conn.py:128-256` 定义 `DocStoreConnection` 接口(dbType / createIdx / search / insert / update / delete / sql 等)。
|
||||
- 表达式族:同文件 43-126 行定义 `MatchTextExpr`、`MatchDenseExpr`、`MatchSparseExpr`、`MatchTensorExpr`、`FusionExpr`、`OrderByExpr` —— 这是上层与底层解耦的"查询 IR"。
|
||||
- ES 实现:`@singleton class ESConnection(DocStoreConnection)`(`api/app/core/rag/utils/es_conn.py:26-634`)。
|
||||
- 全局入口:`api/app/core/rag/common/settings.py:13-24` 在模块导入时即 `init_settings()`,把 `ESConnection()` 装进 `docStoreConn`,并注入 `Dealer` / `KGSearch`。
|
||||
- 对应的检索门面:`api/app/core/rag/nlp/search.py: Dealer`(350-907 行),由 `kg_retriever`、`retriever` 全局共用。
|
||||
|
||||
### 3.2 路径 B:`ElasticSearchVector`(应用层 BaseVector,主要服务于 KB 节点 / 工作流)
|
||||
|
||||
- 抽象基类:`api/app/core/rag/vdb/vector_base.py:9-67` 定义 `BaseVector` 接口(create / add_texts / search_by_vector / search_by_full_text / delete 等)。
|
||||
- 字段命名:`api/app/core/rag/vdb/field.py`:`page_content` / `metadata` / `vector` / `metadata.doc_id` 等。
|
||||
- ES 实现:`class ElasticSearchVector(BaseVector)` + `class ElasticSearchVectorFactory`(`api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:29-732`)。
|
||||
- 关键调用方:
|
||||
- `api/app/core/workflow/nodes/knowledge/node.py:195-298` 工作流知识节点,按 `RetrieveType` 分支调用 `search_by_vector / search_by_full_text`。
|
||||
- `api/app/core/rag/nlp/search.py: knowledge_retrieval`(36-147 行)API/服务层入口。
|
||||
- `api/app/services/memory_konwledges_server.py`、`api/app/controllers/{chunk,document,knowledge}_controller.py` 等。
|
||||
|
||||
### 3.3 两条路径的边界
|
||||
|
||||
| 维度 | 路径 A(ESConnection / Dealer) | 路径 B(ElasticSearchVector) |
|
||||
| --- | --- | --- |
|
||||
| 索引名 | `graphrag_{workspace_id}` | `Vector_index_{kb_id}_Node`(小写)|
|
||||
| 索引粒度 | 一个 workspace 一个 ES index,多 KB 用 `kb_id` 字段过滤 | 一个 KB 一个 ES index |
|
||||
| Mapping | `res/mapping.json` 全局 dynamic_templates | 代码里 inline 的 `index_mapping` (`elasticsearch_vector.py:616-661`) |
|
||||
| 文本字段 | `content_ltks` / `content_sm_ltks` / `title_tks` / `important_kwd` / `*_tks` | `page_content` (`text` + `ik_max_word`) |
|
||||
| 向量字段 | 动态 `q_{dim}_vec` (`*_512_vec` / `*_768_vec` / `*_1024_vec` / `*_1536_vec`) | 固定 `vector`(dim 取首批 embeddings 长度)|
|
||||
| 关键词检索 | Lucene `query_string`(field-boost、同义词、短语)| `match` + `analyzer=ik_max_word`(BM25)|
|
||||
| 向量检索 | `s.knn(...)`(HNSW,ES 8 原生 ANN)| `script_score` + `cosineSimilarity`(暴力,但精度高)|
|
||||
| 混合融合 | `FusionExpr("weighted_sum", weights="0.05,0.95")` 应用层加权 + ES 内部混合 | 双路并发查 → metadata.doc_id 去重 → 可选 reranker |
|
||||
| 主要使用者 | GraphRAG、`Dealer.retrieval()`、tag/citation 等高级能力 | 工作流知识节点、KB CRUD、召回测试 |
|
||||
|
||||
> **why 不合并**:路径 A 携带丰富 IR(同义词扩展、`tag_feas`、`pagerank_fea`、`question_tks` 等),是面向"知识图谱 + 复杂 RAG"的;路径 B 简单直接,是工作流/服务层的"够用就好"封装。代码上是渐进演化中的双轨,但**目前两条路径都在生产使用**。
|
||||
|
||||

|
||||
|
||||
## 四、索引设计
|
||||
|
||||
### 4.1 全局 mapping(路径 A,`api/app/core/rag/res/mapping.json`)
|
||||
|
||||
#### 4.1.1 settings
|
||||
|
||||
```json
|
||||
// api/app/core/rag/res/mapping.json:2-15
|
||||
"settings": {
|
||||
"index": {
|
||||
"number_of_shards": 2,
|
||||
"number_of_replicas": 0,
|
||||
"refresh_interval": "1000ms"
|
||||
},
|
||||
"similarity": {
|
||||
"scripted_sim": {
|
||||
"type": "scripted",
|
||||
"script": {
|
||||
"source": "double idf = Math.log(1+(field.docCount-term.docFreq+0.5)/(term.docFreq + 0.5))/Math.log(1+((field.docCount-0.5)/1.5)); return query.boost * idf * Math.min(doc.freq, 1);"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| 项 | 值 | 说明 |
|
||||
| --- | --- | --- |
|
||||
| `number_of_shards` | 2 | 适合中小型部署;超过 50GB / 单 shard 时需重新规划 |
|
||||
| `number_of_replicas` | 0 | **生产风险点**:单副本意味着任一分片丢失即数据丢失,建议生产环境改为 ≥1 |
|
||||
| `refresh_interval` | 1000ms | 默认 1s 即可见,写入吞吐场景可调高至 30s 或写入期 `-1` |
|
||||
| `scripted_sim` | 自定义 BM25 变体 | 用 `Math.min(doc.freq, 1)` 把词频压成 0/1,等价于 binary BM25——抑制高 TF 的关键字"灌水",对 token 字段更鲁棒 |
|
||||
|
||||
#### 4.1.2 dynamic_templates(按字段名后缀决定字段类型)
|
||||
|
||||
```json
|
||||
// api/app/core/rag/res/mapping.json:25-209(节选)
|
||||
{ "int": { "match": "*_int", "mapping": { "type": "integer", "store": "true" }}},
|
||||
{ "ulong": { "match": "*_ulong", "mapping": { "type": "unsigned_long" }}},
|
||||
{ "long": { "match": "*_long", "mapping": { "type": "long" }}},
|
||||
{ "numeric": { "match": "*_flt", "mapping": { "type": "float" }}},
|
||||
|
||||
{ "tks": { "match": "*_tks", "mapping": { "type": "text", "similarity": "scripted_sim", "analyzer": "whitespace" }}},
|
||||
{ "ltks": { "match": "*_ltks", "mapping": { "type": "text", "analyzer": "whitespace" }}},
|
||||
|
||||
{ "kwd": { "match_pattern": "regex",
|
||||
"match": "^(.*_(kwd|id|ids|uid|uids)|uid)$",
|
||||
"mapping": { "type": "keyword", "similarity": "boolean" }}},
|
||||
{ "dt": { "match_pattern": "regex",
|
||||
"match": "^.*(_dt|_time|_at)$",
|
||||
"mapping": { "type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||yyyy-MM-dd_HH:mm:ss" }}},
|
||||
|
||||
{ "rank_feature": { "match": "*_fea", "mapping": { "type": "rank_feature" }}},
|
||||
{ "rank_features": { "match": "*_feas", "mapping": { "type": "rank_features" }}},
|
||||
|
||||
{ "dense_vector": { "match": "*_512_vec", "mapping": { "type": "dense_vector", "index": true, "similarity": "cosine", "dims": 512 }}},
|
||||
{ "dense_vector": { "match": "*_768_vec", "mapping": { "type": "dense_vector", "index": true, "similarity": "cosine", "dims": 768 }}},
|
||||
{ "dense_vector": { "match": "*_1024_vec", "mapping": { "type": "dense_vector", "index": true, "similarity": "cosine", "dims": 1024 }}},
|
||||
{ "dense_vector": { "match": "*_1536_vec", "mapping": { "type": "dense_vector", "index": true, "similarity": "cosine", "dims": 1536 }}},
|
||||
|
||||
{ "nested": { "match": "*_nst", "mapping": { "type": "nested" }}},
|
||||
{ "binary": { "match": "*_bin", "mapping": { "type": "binary" }}}
|
||||
```
|
||||
|
||||
**why dynamic 而不是 strict mapping**:
|
||||
|
||||
- 不同 embedding 模型维度不同(512/768/1024/1536),通过字段名后缀让"模型即维度",在 `nlp/search.py:372` 看到查询侧动态拼名 `f"q_{len(embedding_data)}_vec"`,写入侧也是同样命名,零配置切换 embedding。
|
||||
- token 字段分 `*_tks` 与 `*_ltks`:前者使用 `scripted_sim`(去 TF),用于 important_kwd 这类"命中即可"字段;后者 BM25 默认,用于正文型 `content_ltks`。
|
||||
- `*_fea` (rank_feature) 与 `*_feas` (rank_features) 用于 PageRank 与 tag 加权,详见检索章节的 `_rank_feature_scores`。
|
||||
|
||||
> **why analyzer 是 `whitespace` 而不是 IK**:路径 A 在写入前先用 `rag_tokenizer` 在应用层做完中文分词,写入 ES 时已经是空格分隔的 tokens。这样"分词逻辑"留在应用层,便于热更新词典与同义词,不用 reindex。
|
||||
|
||||
### 4.2 路径 B 的 inline mapping(KB 索引)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:609-663
|
||||
def create_collection(self, embeddings, metadatas=None, index_params=None):
|
||||
if not self._client.indices.exists(index=self._collection_name):
|
||||
index_mapping = {
|
||||
"mappings": {
|
||||
"properties": {
|
||||
Field.CONTENT_KEY.value: { # "page_content"
|
||||
"type": "text",
|
||||
"analyzer": "ik_max_word"
|
||||
},
|
||||
Field.METADATA_KEY.value: { # "metadata"
|
||||
"type": "object",
|
||||
"properties": {
|
||||
"doc_id": {"type": "keyword"},
|
||||
"file_id": {"type": "keyword"},
|
||||
"file_name": {"type": "keyword"},
|
||||
"file_created_at": {"type": "date", "format": "epoch_millis"},
|
||||
"document_id": {"type": "keyword"},
|
||||
"knowledge_id": {"type": "keyword"},
|
||||
"sort_id": {"type": "long"},
|
||||
"status": {"type": "integer"}
|
||||
}
|
||||
},
|
||||
Field.VECTOR.value: { # "vector"
|
||||
"type": "dense_vector",
|
||||
"dims": len(embeddings[0]),
|
||||
"index": True,
|
||||
"similarity": "cosine"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
self._client.indices.create(index=self._collection_name, body=index_mapping)
|
||||
```
|
||||
|
||||
要点:
|
||||
|
||||
- 索引按 KB 隔离:`collection_name = f"Vector_index_{knowledge.id}_Node"`(同文件 738 行),ES 端要求小写,所以 `super().__init__(index_name.lower())`(32 行)。
|
||||
- `dims = len(embeddings[0])` —— 维度由"第一批数据"决定,**一旦确定不可改**。换 embedding 模型必须重建索引(详见 §6 风险点)。
|
||||
- `similarity = "cosine"` —— 写入向量不要求归一化,由 ES 内部计算余弦相似度。
|
||||
- 没有显式 `number_of_shards`/`replicas` 设置,**走 ES 集群默认**(8.x 默认 1 shard 1 replica),可用性比路径 A 反而更好;但碎片化风险也更高(每个 KB 一个 index,KB 多了 cluster state 会膨胀)。
|
||||
|
||||
### 4.3 索引命名与隔离
|
||||
|
||||
| 路径 | 索引模板 | 来源 |
|
||||
| --- | --- | --- |
|
||||
| A | `graphrag_{workspace_id}` | `nlp/search.py:346` `def index_name(uid): return f"graphrag_{uid}"` |
|
||||
| B | `Vector_index_{kb_id}_Node`(小写)| `elasticsearch_vector.py:738` |
|
||||
|
||||
路径 A 在删除知识库时**故意不删 ES 索引**,而是仅删 `kb_id` 维度的文档:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:115-124
|
||||
def deleteIdx(self, indexName: str, knowledgebaseId: str):
|
||||
if len(knowledgebaseId) > 0:
|
||||
# The index need to be alive after any kb deletion since all kb under this workspace are in one index.
|
||||
return
|
||||
try:
|
||||
self.es.indices.delete(index=indexName, allow_no_indices=True)
|
||||
except NotFoundError:
|
||||
pass
|
||||
```
|
||||
|
||||
> **why**:一个 workspace 多 KB 共享同一个 index,单 KB 删除不能动 index;只能在 `delete()` 通过 `condition["kb_id"]=knowledgebaseId` 走 delete-by-query(同文件 424-471)。
|
||||
|
||||
---
|
||||
|
||||
## 五、写入链路
|
||||
|
||||
### 5.1 路径 B:高层封装(KB / 工作流场景)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:55-87
|
||||
def add_chunks(self, chunks: list[DocumentChunk], **kwargs):
|
||||
texts = [chunk.page_content for chunk in chunks]
|
||||
if self.is_multimodal_embedding:
|
||||
embeddings = self.embeddings.embed_batch(texts)
|
||||
else:
|
||||
embeddings = self.embeddings.embed_documents(list(texts))
|
||||
self.create(chunks, embeddings, **kwargs)
|
||||
|
||||
def create(self, chunks, embeddings, **kwargs):
|
||||
metadatas = [chunk.metadata or {} for chunk in chunks]
|
||||
if not self._client.indices.exists(index=self._collection_name):
|
||||
self.create_collection(embeddings, metadatas) # 懒建索引
|
||||
self.add_texts(chunks, embeddings, **kwargs)
|
||||
|
||||
def add_texts(self, chunks, embeddings, **kwargs):
|
||||
uuids = self._get_uuids(chunks)
|
||||
actions = []
|
||||
for i, chunk in enumerate(chunks):
|
||||
actions.append({
|
||||
"_index": self._collection_name,
|
||||
"_source": {
|
||||
Field.CONTENT_KEY.value: chunk.page_content,
|
||||
Field.METADATA_KEY.value: chunk.metadata or {},
|
||||
Field.VECTOR.value: embeddings[i] or None,
|
||||
}
|
||||
})
|
||||
result = helpers.bulk(self._client, actions)
|
||||
return uuids
|
||||
```
|
||||
|
||||
特性:
|
||||
|
||||
- **懒建索引**:第一次写入时根据 `len(embeddings[0])` 建 mapping。
|
||||
- **批量写**:`elasticsearch.helpers.bulk` 默认 chunk_size=500、max_chunk_bytes=100MB;这里不传 `_id`,ES 自动生成。
|
||||
- **唯一性**:路径 B 把 chunk 唯一标识放在 `metadata.doc_id`(`vector_base.py:62-63 _get_uuids`),更新/删除走"先 search by metadata.doc_id 拿真正 _id 再 bulk delete"两步走(`elasticsearch_vector.py:148-174`)。
|
||||
- **失败处理**:`helpers.bulk` 默认抛 `BulkIndexError`,调用方在 `delete_by_ids / delete_by_metadata_field` 中分桶捕获 404 与其它错误(同文件 137-147、164-174)。**`add_texts` 没有捕获**——一旦底层网络失败会向上抛,调用方需要保证幂等性或重试。
|
||||
|
||||
### 5.2 路径 A:抽象层批量写
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:294-330
|
||||
def insert(self, documents, indexName, knowledgebaseId=None) -> list[str]:
|
||||
operations = []
|
||||
for d in documents:
|
||||
assert "_id" not in d
|
||||
assert "id" in d
|
||||
d_copy = copy.deepcopy(d)
|
||||
d_copy["kb_id"] = knowledgebaseId
|
||||
meta_id = d_copy.pop("id", "")
|
||||
operations.append({"index": {"_index": indexName, "_id": meta_id}})
|
||||
operations.append(d_copy)
|
||||
|
||||
res = []
|
||||
for _ in range(ATTEMPT_TIME): # 默认 2 次
|
||||
try:
|
||||
r = self.es.bulk(index=indexName, operations=operations,
|
||||
refresh=False, timeout="60s")
|
||||
if re.search(r"False", str(r["errors"]), re.IGNORECASE):
|
||||
return res
|
||||
for item in r["items"]:
|
||||
for action in ["create", "delete", "index", "update"]:
|
||||
if action in item and "error" in item[action]:
|
||||
res.append(str(item[action]["_id"]) + ":" + str(item[action]["error"]))
|
||||
return res
|
||||
except ConnectionTimeout:
|
||||
time.sleep(3); self._connect(); continue
|
||||
except Exception as e:
|
||||
res.append(str(e)); break
|
||||
return res
|
||||
```
|
||||
|
||||
要点:
|
||||
|
||||
- **显式 `_id = id`**:调用方自己保证 chunk_id 唯一(典型实现:`uuid4()` 或基于 `doc_id+chunk_idx` 的稳定 hash),重复写入即"覆盖式更新",天然支持幂等重试。
|
||||
- **强制注入 `kb_id`**:所有 chunk 都打上 `kb_id` 标签,作为多租户隔离与 delete-by-query 的依据。
|
||||
- **refresh=False**:写入不等可见,吞吐优先;查询侧通过 1s 默认 refresh 间隔获得近实时性。
|
||||
- **显式 timeout="60s"** + ATTEMPT_TIME=2 重连 —— 网络抖动会自动重试一次。
|
||||
- **失败回滚?** 只返回失败列表,**不做事务回滚**。这是 ES 的典型用法:bulk 是 best-effort,调用方需要根据返回值决定是否补偿(如 chunker 重新生成失败 chunk)。
|
||||
|
||||
### 5.3 增量更新(路径 A)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:332-422
|
||||
def update(self, condition, newValue, indexName, knowledgebaseId) -> bool:
|
||||
# 单文档 update
|
||||
if "id" in condition and isinstance(condition["id"], str):
|
||||
chunkId = condition["id"]
|
||||
# 删除字段(带 _feas 后缀的 rank_features 必须先 remove 再 set,否则旧 token 残留)
|
||||
for k in doc.keys():
|
||||
if k.split("_")[-1] == "feas":
|
||||
self.es.update(index=indexName, id=chunkId, script=f"ctx._source.remove(\"{k}\");")
|
||||
self.es.update(index=indexName, id=chunkId, doc=doc)
|
||||
return True
|
||||
|
||||
# 批量 update_by_query:构造 painless 脚本
|
||||
bqry = Q("bool")
|
||||
# ... 把 condition 转成 filter
|
||||
scripts = []; params = {}
|
||||
for k, v in newValue.items():
|
||||
if k == "remove": # remove 单个 list 元素
|
||||
scripts.append(f"int i=ctx._source.{kk}.indexOf(params.p_{kk});ctx._source.{kk}.remove(i);")
|
||||
elif k == "add": # 向 list 追加
|
||||
scripts.append(f"ctx._source.{kk}.add(params.pp_{kk});")
|
||||
elif isinstance(v, str):
|
||||
v = re.sub(r"(['\n\r]|\\.)", " ", v) # 防止脚本注入
|
||||
scripts.append(f"ctx._source.{k}=params.pp_{k};")
|
||||
...
|
||||
ubq = UpdateByQuery(index=indexName).using(self.es).query(bqry)\
|
||||
.script(source="".join(scripts), params=params)\
|
||||
.params(refresh=True, slices=5, conflicts="proceed")
|
||||
ubq.execute()
|
||||
```
|
||||
|
||||
亮点:
|
||||
|
||||
- **slices=5** —— 并行 update-by-query,写吞吐放大 5 倍。
|
||||
- **conflicts="proceed"** —— 遇到版本冲突跳过而不中止任务;适合"标签批量更新"这种最终一致场景。
|
||||
- **rank_features 必须先 remove**:因为 `*_feas` 是"key→score"字典,新值无法覆盖旧 key(341-346 行的 patch)。
|
||||
- **input sanitation**:对 string 值做 `re.sub(r"(['\n\r]|\\.)", " ", v)` 防止 painless 脚本注入。
|
||||
|
||||
### 5.4 路径 B 的 update_by_query
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:299-342
|
||||
def update_by_segment(self, chunk: DocumentChunk, **kwargs) -> str:
|
||||
if self.is_multimodal_embedding:
|
||||
chunk.vector = self.embeddings.embed_text(chunk.page_content)
|
||||
else:
|
||||
chunk.vector = self.embeddings.embed_query(chunk.page_content)
|
||||
body = {
|
||||
"script": {
|
||||
"source": """
|
||||
ctx._source.page_content = params.new_content;
|
||||
ctx._source.vector = params.new_vector;
|
||||
""",
|
||||
"params": {"new_content": chunk.page_content, "new_vector": chunk.vector}
|
||||
},
|
||||
"query": {"term": {Field.DOC_ID.value: chunk.metadata["doc_id"]}}
|
||||
}
|
||||
return self._client.update_by_query(index=indices, body=body)['updated']
|
||||
```
|
||||
|
||||
注意:`metadata.doc_id`(关键字段) 一查多匹配 → 全部刷新内容与向量。这是路径 B 的"chunk 更新"语义,**没有版本控制**,并发更新会以最后写入为准;需要严格控制时应在调用方加锁或退化为先 `delete_by_ids` 再 `add_chunks`。
|
||||
|
||||
---
|
||||
|
||||
## 六、检索链路
|
||||
|
||||
### 6.1 三种检索类型(应用层枚举)
|
||||
|
||||
```python
|
||||
# api/app/schemas/chunk_schema.py:8-13
|
||||
class RetrieveType(StrEnum):
|
||||
PARTICIPLE = "participle" # 关键词 / 分词检索(BM25)
|
||||
SEMANTIC = "semantic" # 语义 / 向量检索(cosine)
|
||||
HYBRID = "hybrid" # 混合检索:双路 + 去重 (+ rerank)
|
||||
Graph = "graph" # 在 hybrid 之上叠加 GraphRAG 检索
|
||||
```
|
||||
|
||||
在 `api/app/core/workflow/nodes/knowledge/node.py:213-298` 与 `api/app/core/rag/nlp/search.py:220-281` 两处可以看到完全一致的三分支 + 默认走 hybrid 的派发逻辑。
|
||||
|
||||
### 6.2 关键词检索(路径 B:BM25 + IK)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:468-558(节选)
|
||||
def search_by_full_text(self, query: str, **kwargs) -> list[DocumentChunk]:
|
||||
top_k = kwargs.get("top_k", 1024)
|
||||
score_threshold = float(kwargs.get("score_threshold") or 0.2)
|
||||
file_names_filter = kwargs.get("file_names_filter")
|
||||
|
||||
query_str = {
|
||||
"bool": {
|
||||
"must": {
|
||||
"match": {
|
||||
Field.CONTENT_KEY.value: {
|
||||
"query": query,
|
||||
"analyzer": "ik_max_word" # 与建索引时一致
|
||||
}
|
||||
}
|
||||
},
|
||||
"filter": {"term": {"metadata.status": 1}} # 只看启用状态
|
||||
}
|
||||
}
|
||||
# 可选叠加 file_name 多选过滤
|
||||
if file_names_filter:
|
||||
query_str["bool"]["filter"] = [
|
||||
{"term": {"metadata.status": 1}},
|
||||
{"terms": {"metadata.file_name": file_names_filter}}
|
||||
]
|
||||
|
||||
result = self._client.search(index=indices, from_=0, size=top_k, query=query_str)
|
||||
max_score = result["hits"]["max_score"] or 1.0
|
||||
docs_and_scores = []
|
||||
for res in result["hits"]["hits"]:
|
||||
normalized_score = res["_score"] / max_score # 归一化到 [0,1]
|
||||
...
|
||||
return [doc for doc, score in docs_and_scores if score > score_threshold]
|
||||
```
|
||||
|
||||
要点:
|
||||
|
||||
- BM25 默认相似度,`ik_max_word` 中文分词;写入与查询使用同一 analyzer,避免分词错位。
|
||||
- **score 归一化**:BM25 score 是开放区间,除以 `max_score` 缩放到 [0,1],便于与 `score_threshold` 比较,也便于和向量分数同尺度对齐。
|
||||
- 默认 `score_threshold=0.2`、`top_k=1024`。
|
||||
|
||||
### 6.3 关键词检索(路径 A:query_string + 同义词扩展)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/query.py:69-201(节选)
|
||||
class FulltextQueryer:
|
||||
query_fields = [
|
||||
"title_tks^10", "title_sm_tks^5",
|
||||
"important_kwd^30", "important_tks^20",
|
||||
"question_tks^20",
|
||||
"content_ltks^2", "content_sm_ltks",
|
||||
]
|
||||
|
||||
def question(self, txt, tbl="qa", min_match: float = 0.6):
|
||||
txt = self.add_space_between_eng_zh(txt) # 中英分词预处理
|
||||
txt = self.rmWWW(txt) # 去问句词(怎么/吗/啥/what/how/...)
|
||||
...
|
||||
# 中文分支:term_weight 权重 + synonym 同义词扩展
|
||||
for tt in self.tw.split(txt)[:256]:
|
||||
twts = self.tw.weights([tt])
|
||||
syns = self.syn.lookup(tt)
|
||||
tk_syns = [f"({tk} OR (%s)^0.2)" % " ".join(tk_syns), ...] # 同义词权重 0.2
|
||||
tms.append((tk, w))
|
||||
query = " OR ".join([f"({t})" for t in qs if t])
|
||||
return MatchTextExpr(self.query_fields, query, 100,
|
||||
{"minimum_should_match": min_match}), keywords
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:196-217
|
||||
for m in matchExprs:
|
||||
if isinstance(m, MatchTextExpr):
|
||||
minimum_should_match = m.extra_options.get("minimum_should_match", 0.0)
|
||||
if isinstance(minimum_should_match, float):
|
||||
minimum_should_match = str(int(minimum_should_match * 100)) + "%"
|
||||
bqry.must.append(Q("query_string", fields=m.fields,
|
||||
type="best_fields", query=m.matching_text,
|
||||
minimum_should_match=minimum_should_match,
|
||||
boost=1))
|
||||
bqry.boost = 1.0 - vector_similarity_weight
|
||||
```
|
||||
|
||||
亮点:
|
||||
|
||||
- **多字段 field-boost**:`important_kwd^30` 表示标签字段权重远高于正文,符合"重要标签命中即高排名"的直觉。
|
||||
- **同义词加权 0.2**:同义词召回但低权重,避免"同义词稀释"主体相关性。
|
||||
- **minimum_should_match**:默认 0.3 / 0.6,控制 BM25 召回的"严苛度"。当 hybrid 总命中为 0 时会 fallback 到 0.1 重试(详见 6.7)。
|
||||
- **`type="best_fields"`**:多字段场景取每字段最高分作为最终分,符合"标题命中比正文命中更重要"的语义。
|
||||
|
||||
### 6.4 向量检索(路径 B:script_score + cosine)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:374-466(节选)
|
||||
def search_by_vector(self, query: str, **kwargs) -> list[DocumentChunk]:
|
||||
if self.is_multimodal_embedding:
|
||||
query_vector = self.embeddings.embed_text(query)
|
||||
else:
|
||||
query_vector = self.embeddings.embed_query(query)
|
||||
top_k = kwargs.get("top_k", 1024)
|
||||
score_threshold = float(kwargs.get("score_threshold") or 0.3)
|
||||
file_names_filter = kwargs.get("file_names_filter")
|
||||
|
||||
query_str = {
|
||||
"bool": {
|
||||
"must": {
|
||||
"script_score": {
|
||||
"query": {"match_all": {}},
|
||||
"script": {
|
||||
# cosineSimilarity 范围 [-1,1],+1 后落到 [0,2]
|
||||
"source": f"cosineSimilarity(params.query_vector, '{Field.VECTOR.value}') + 1.0",
|
||||
"params": {"query_vector": query_vector}
|
||||
}
|
||||
}
|
||||
},
|
||||
"filter": {"term": {"metadata.status": 1}}
|
||||
}
|
||||
}
|
||||
|
||||
result = self._client.search(index=indices, from_=0, size=top_k, query=query_str)
|
||||
docs_and_scores = []
|
||||
for res in result["hits"]["hits"]:
|
||||
score = res["_score"] / 2 # [0,2] -> [0,1]
|
||||
docs_and_scores.append((..., score))
|
||||
return [doc for doc, score in docs_and_scores if score > score_threshold]
|
||||
```
|
||||
|
||||
特性与权衡:
|
||||
|
||||
- **script_score 是暴力扫描**:会对 `match_all` 命中的所有文档(叠加 status=1 filter 后)逐一算 cosine,复杂度 O(N·dim)。优点是结果**精确**、无 ANN 召回率损失;缺点是延迟随 KB chunk 数线性增长,不适合 chunk 量级大的 KB。
|
||||
- **score 归一化**:`(cos+1)/2 ∈ [0,1]`,与 BM25 归一化值同尺度。
|
||||
- **过滤集成**:`metadata.status=1` 在 filter 上,先过滤再算分;`file_names_filter` 同理。
|
||||
|
||||
### 6.5 向量检索(路径 A:knn + filter)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:206-217
|
||||
elif isinstance(m, MatchDenseExpr):
|
||||
similarity = m.extra_options.get("similarity", 0.0)
|
||||
s = s.knn(
|
||||
m.vector_column_name,
|
||||
m.topn,
|
||||
m.topn * 2, # num_candidates = 2 * k,控制召回率
|
||||
query_vector=list(m.embedding_data),
|
||||
filter=bqry.to_dict(), # 与 BM25 同一份 bool filter
|
||||
# similarity=similarity # 已注释:未启用阈值剪枝
|
||||
)
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/search.py:365-373
|
||||
def get_vector(self, txt, emb_mdl, topk=10, similarity=0.1):
|
||||
qv, _ = emb_mdl.encode_queries(txt)
|
||||
embedding_data = [get_float(v) for v in qv]
|
||||
vector_column_name = f"q_{len(embedding_data)}_vec" # 动态选维度
|
||||
return MatchDenseExpr(vector_column_name, embedding_data,
|
||||
'float', 'cosine', topk, {"similarity": similarity})
|
||||
```
|
||||
|
||||
要点:
|
||||
|
||||
- **HNSW ANN**:路径 A 用的是 ES 8 原生 `knn` query,底层 HNSW 索引,毫秒级,但有近似召回率损失。
|
||||
- **k vs num_candidates**:`topn * 2` 即 ANN 阶段先取 2k 候选再精排到 k,是召回率与延迟的折中。生产建议至少 `4 * topn`,更高召回。
|
||||
- **filter 共享**:`filter=bqry.to_dict()`——把 BM25 那份 bool filter 同时挂在 knn 上,确保过滤条件在 ANN 内部应用(pre-filter);这点对多租户 `kb_id` 隔离尤为关键,否则 ANN 先取 top-k 再过滤,可能完全不返回该 KB 的文档。
|
||||
- **similarity 阈值已注释**:当前不启用 ES 内置阈值剪枝;需要按相似度阈值过滤的话,由应用层 (`Dealer.retrieval`) 在 rerank 阶段做。
|
||||
|
||||
### 6.6 混合搜索 —— 这是本节最关键的"融合公式"
|
||||
|
||||
#### 6.6.1 路径 A:`FusionExpr("weighted_sum")` + ES 内部混合(**核心融合点**)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/search.py:435-445
|
||||
matchDense = self.get_vector(qst, emb_mdl, topk, req.get("similarity", 0.1))
|
||||
q_vec = matchDense.embedding_data
|
||||
src.append(f"q_{len(q_vec)}_vec")
|
||||
|
||||
fusionExpr = FusionExpr("weighted_sum", topk, {"weights": "0.05,0.95"})
|
||||
matchExprs = [matchText, matchDense, fusionExpr]
|
||||
|
||||
res = self.dataStore.search(src, highlightFields, filters, matchExprs, orderBy,
|
||||
offset, limit, idx_names, kb_ids, rank_feature=rank_feature)
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:186-218
|
||||
s = Search()
|
||||
vector_similarity_weight = 0.5
|
||||
for m in matchExprs:
|
||||
if isinstance(m, FusionExpr) and m.method == "weighted_sum" and "weights" in m.fusion_params:
|
||||
# 必须按 [text, dense, fusion] 顺序传入
|
||||
assert len(matchExprs) == 3 and isinstance(matchExprs[0], MatchTextExpr) \
|
||||
and isinstance(matchExprs[1], MatchDenseExpr) and isinstance(matchExprs[2], FusionExpr)
|
||||
weights = m.fusion_params["weights"]
|
||||
vector_similarity_weight = get_float(weights.split(",")[1]) # "0.05,0.95" -> 0.95
|
||||
|
||||
for m in matchExprs:
|
||||
if isinstance(m, MatchTextExpr):
|
||||
...
|
||||
bqry.must.append(Q("query_string", ..., boost=1))
|
||||
bqry.boost = 1.0 - vector_similarity_weight # text 整体 boost = 0.05
|
||||
elif isinstance(m, MatchDenseExpr):
|
||||
s = s.knn(m.vector_column_name, m.topn, m.topn * 2,
|
||||
query_vector=list(m.embedding_data), filter=bqry.to_dict())
|
||||
if bqry:
|
||||
s = s.query(bqry)
|
||||
```
|
||||
|
||||
**融合公式**(这是 [S2-T7] 评审要求"必须明确"的部分):
|
||||
|
||||
```
|
||||
final_score(doc) = (1 - w_vec) * BM25_query_string_score(doc)
|
||||
+ w_vec * knn_cosine_score(doc)
|
||||
+ Σ rank_feature_score(doc) ← PageRank + tag 加权(可选)
|
||||
```
|
||||
|
||||
其中:
|
||||
|
||||
- `w_vec = 0.95`(来自 `FusionExpr` 的 `"weights": "0.05,0.95"` 第二个权重)。
|
||||
- BM25 整体 `bqry.boost = 0.05`,即 `query_string` 的 BM25 分数被乘 0.05;knn 的分数没有显式 boost,相当于权重 1.0,但语义上由调用方约定 0.95(**即代码层面是"BM25 直接乘 0.05,knn 不缩放",并未严格归一化到等比例**——这是一个已知近似,见 6.7 fallback)。
|
||||
- 排序逻辑:ES 8 的 hybrid 行为是"bool query 命中集 ∪ knn top-k 候选集",并集后用各自分数相加(未命中那侧分数为 0)。`elasticsearch-dsl Search` 的 `.query(...).knn(...)` 组合自动启用此模式。
|
||||
- `rank_feature` 通过 `bqry.should.append(Q("rank_feature", field=fld, linear={}, boost=sc))`(es_conn.py:219-223)以**加性**方式融入最终分。
|
||||
|
||||
> 这种"应用层约定 + ES 端 boost 缩放"的混合不是教科书式的归一化加权,但工程上简单:BM25 与 cosine 在统计上不同尺度,0.05/0.95 的**极端偏向语义**是为了"以语义检索为主、关键词作为补强"。
|
||||
|
||||
#### 6.6.2 路径 B:双路 + 去重 + 可选 Rerank
|
||||
|
||||
```python
|
||||
# api/app/core/workflow/nodes/knowledge/node.py:236-271
|
||||
case retrieve_type if retrieve_type in (RetrieveType.HYBRID, RetrieveType.Graph):
|
||||
rs1_task = asyncio.to_thread(vector_service.search_by_vector, **{
|
||||
"query": query, "top_k": kb_config.top_k,

})
|

rs2_task = asyncio.to_thread(vector_service.search_by_full_text, **{

||||
"query": query, "top_k": kb_config.top_k,
|
||||
"indices": indices, "score_threshold": kb_config.similarity_threshold
|
||||
})
|
||||
rs1, rs2 = await asyncio.gather(rs1_task, rs2_task) # 双路并发
|
||||
|
||||
unique_rs = self._deduplicate_docs(rs1, rs2) # 按 doc_id 去重
|
||||
if not unique_rs: return []
|
||||
if self.typed_config.reranker_id:
|

rs.extend(await asyncio.to_thread(
|
||||
self.rerank, **{"query": query, "docs": unique_rs, "top_k": kb_config.top_k}))
|
||||
else:
|
||||
rs.extend(sorted(unique_rs,
|
||||
key=lambda d: d.metadata.get("score", 0),
|
||||
reverse=True)[:kb_config.top_k])
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/search.py:236-261(同等逻辑的同步版)
|
||||
case _:
|
||||
rs1 = vector_service.search_by_vector(...)
|
||||
rs2 = vector_service.search_by_full_text(...)
|
||||
seen_ids = set(); unique_rs = []
|
||||
for doc in rs1 + rs2:
|
||||
if doc.metadata["doc_id"] not in seen_ids:
|
||||
seen_ids.add(doc.metadata["doc_id"])
|
||||
unique_rs.append(doc)
|
||||
rs = unique_rs
|
||||
if unique_rs:
|
||||
rs = vector_service.rerank(query=..., docs=unique_rs, top_k=...)
|
||||
```
|
||||
|
||||
**融合公式**(路径 B):
|
||||
|
||||
```
|
||||
candidates = vector_topk(q, w_v) ∪ bm25_topk(q, w_t) # 双路并发召回
|

|
||||
if reranker:
|
||||
final = reranker(query, deduped)[:top_k] # 跨编码器重排
|
||||
else:
|
||||
final = sort_by_score_desc(deduped)[:top_k] # 各自归一化分数直接比
|
||||
```
|
||||
|
||||
> **why 不在路径 B 做加权融合**:路径 B 双路分数已分别归一化到 [0,1],但"BM25 归一化分"与"cosine 归一化分"之间**不可比**(一个是相对最大分,一个是绝对几何相似度)。直接把它们排序虽然不严谨,但通常依赖下游的 cross-encoder reranker 做最终排序,因此前置阶段以"召回多样性"为优先(vector 主召回 + BM25 补关键词),不再做权重融合。
|
||||
|
||||
### 6.7 兜底:低召回 fallback
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/search.py:447-459
|
||||
# If result is empty, try again with lower min_match
|
||||
if total == 0:
|
||||
if filters.get("document_id"):
|
||||
# 限定文档场景下,直接退化为"无关键词"召回
|
||||
res = self.dataStore.search(src, [], filters, [], orderBy, offset, limit, idx_names, kb_ids)
|
||||
total = self.dataStore.getTotal(res)
|
||||
else:
|
||||
matchText, _ = self.qryr.question(qst, min_match=0.1) # 0.3 -> 0.1
|
||||
matchDense.extra_options["similarity"] = 0.17 # 0.1 -> 0.17(提高语义阈值)
|
||||
res = self.dataStore.search(src, highlightFields, filters,
|
||||
[matchText, matchDense, fusionExpr],
|
||||
orderBy, offset, limit, idx_names, kb_ids,
|
||||
rank_feature=rank_feature)
|
||||
```
|
||||
|
||||
> **设计意图**:第一轮严格匹配(min_match=0.3)保证精度;命中为 0 时放宽 BM25 但提高向量阈值,等价于"换主导侧",避免空结果。
|
||||
|
||||
### 6.8 Rerank:模型重排 + 应用层混合相似度
|
||||
|
||||
`Dealer.rerank_by_model` 与 `Dealer.rerank` 是两套 reranker:
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/search.py:606-666
|
||||
def rerank(self, sres, query, tkweight=0.3, vtweight=0.7, ...):
|
||||
sim, tksim, vtsim = self.qryr.hybrid_similarity(
|
||||
sres.query_vector, ins_embd, keywords, ins_tw, tkweight, vtweight)
|
||||
return sim + rank_fea, tksim, vtsim
|
||||
|
||||
def rerank_by_model(self, rerank_mdl, sres, query, tkweight=0.3, vtweight=0.7, ...):
|
||||
tksim = self.qryr.token_similarity(keywords, ins_tw)
|
||||
vtsim, _ = rerank_mdl.similarity(query, [...])
|
||||
return tkweight * (np.array(tksim) + rank_fea) + vtweight * vtsim, tksim, vtsim
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/nlp/query.py:203-211
|
||||
def hybrid_similarity(self, avec, bvecs, atks, btkss, tkweight=0.3, vtweight=0.7):
|
||||
sims = CosineSimilarity([avec], bvecs)
|
||||
tksim = self.token_similarity(atks, btkss)
|
||||
if np.sum(sims[0]) == 0:
|
||||
return np.array(tksim), tksim, sims[0]
|
||||
return np.array(sims[0]) * vtweight + np.array(tksim) * tkweight, tksim, sims[0]
|
||||
```
|
||||
|
||||
应用层重排公式:
|
||||
|
||||
```
|
||||
final_score = vtweight * cosine(q_vec, c_vec) + tkweight * token_sim(q, c) + rank_feature_score
|
||||
≈ 0.7 * vector_sim + 0.3 * keyword_sim + (PageRank + tag)
|
||||
```
|
||||
|
||||
注意 `Dealer.retrieval()`(674-768 行)调用时传入的是 `1 - vector_similarity_weight, vector_similarity_weight`,所以这两个权重由调用方(用户配置)决定,默认 0.3 / 0.7(`vector_similarity_weight=0.3` 见 678 行)。
|
||||
|
||||
### 6.9 top_k / 召回率 / 延迟权衡
|
||||
|
||||
| 阶段 | 默认值 | 含义 | 调参建议 |
|
||||
| --- | --- | --- | --- |
|
||||
| `top_k` (KB 节点) | 工作流配置 | 单 KB 单路召回数 | hybrid 模式建议 ≥ 50;语义高质 KB 可 30 |
|
||||
| `topn` / `topk` (Dealer) | 1024 (ann fallback),10 (默认) | knn 阶段 k | 与下游 RERANK_LIMIT 联动 |
|
||||
| `num_candidates` | `topn * 2` (es_conn.py:213) | HNSW 候选数,影响召回率 | 高召回场景改为 `4 * topn` |
|
||||
| `RERANK_LIMIT` | `ceil(64/page_size)*page_size` (search.py:683) | rerank 输入数 | 与显示页大小绑定,避免 rerank 过多 |
|
||||
| `score_threshold` (BM25) | 0.2 | 归一化后阈值 | 关键词强场景可调到 0.3 |
|
||||
| `score_threshold` (vector) | 0.3 | (cos+1)/2 后阈值 | 严苛去噪可到 0.5 |
|
||||
| `min_match` | 0.3,fallback 0.1 | BM25 词命中比 | 短查询调高,长查询调低 |
|
||||
| `request_timeout` | 30s | ES 客户端超时 | 高并发下 60s |
|
||||
| `search timeout` | "600s" (es_conn.py:257) | ES 服务端超时 | 超长 KB 才放宽 |
|
||||
|
||||
---
|
||||
|
||||
## 七、配置项与运维要点
|
||||
|
||||
### 7.1 环境变量(连接 + 客户端调优)
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:60-80
|
||||
# api/app/core/rag/vdb/elasticsearch/elasticsearch_vector.py:685-710
|
||||
ELASTICSEARCH_HOST # 默认 127.0.0.1,可填 http://es-1 / https://es-1
|
||||
ELASTICSEARCH_PORT # 默认 9200
|
||||
ELASTICSEARCH_USERNAME # 默认 elastic
|
||||
ELASTICSEARCH_PASSWORD # 默认 elastic
|
||||
ELASTICSEARCH_REQUEST_TIMEOUT # 默认 30 (秒)
|
||||
ELASTICSEARCH_RETRY_ON_TIMEOUT # 默认 True (es_conn 中是字符串比较,注意 bug 见下)
|
||||
ELASTICSEARCH_MAX_RETRIES # 默认 3
|
||||
ELASTICSEARCH_VERIFY_CERTS # 默认 false
|
||||
ELASTICSEARCH_CA_CERTS # 自签证书路径
|
||||
ELASTICSEARCH_CONNECTIONS_PER_NODE # 路径 B 独有,默认 10
|
||||
```
|
||||
|
||||
> **小坑**:`es_conn.py:72` 写的是 `os.getenv("ELASTICSEARCH_RETRY_ON_TIMEOUT", True) == "true"`——默认值是 bool `True`,但与字符串 `"true"` 比较恒为 `False`。所以**默认情况下其实没开启 retry_on_timeout**,需要显式设置 `ELASTICSEARCH_RETRY_ON_TIMEOUT=true`(小写)才生效。
|
||||
|
||||
### 7.2 ES 集群规模建议
|
||||
|
||||
按 `mapping.json` 默认 2 shards、0 replicas,**不可直接用于生产**。建议:
|
||||
|
||||
| 数据量 | 节点数 | shards | replicas | heap | 备注 |
|
||||
| --- | --- | --- | --- | --- | --- |
|
||||
| < 100w chunks | 1-3 | 2 | 1 | 8GB | 默认配置 + 1 副本 |
|
||||
| 100w-1000w | 3-5 | 4-8 | 1 | 16GB | 增加 shard 减少单 shard 体积 |
|
||||
| > 1000w | 5+ | 8-16 | 1-2 | 31GB(不超过 32) | shard 大小控制在 30-50GB |
|
||||
|
||||
**核心准则**:
|
||||
|
||||
- 单 shard 不超过 50GB;
|
||||
- replicas ≥ 1,至少容忍 1 节点宕机;
|
||||
- JVM heap 不超过 32GB(zero-based compressed oops);
|
||||
- 留 50% RAM 给 OS file cache(lucene 依赖 mmap)。
|
||||
|
||||
### 7.3 索引膨胀治理
|
||||
|
||||
观察点:
|
||||
|
||||
- **路径 A 的 `graphrag_{workspace_id}` 索引**:随 workspace chunk 数增长,`number_of_shards=2` 容易超过 50GB/shard。需要按"workspace 容量分层",对热门/大 workspace 单独 reindex 到更多 shards。
|
||||
- **路径 B 的 `Vector_index_{kb_id}_Node` 索引**:每 KB 一个 index,KB 数 1000+ 时 cluster state 显著膨胀,可能拖慢所有索引创建/查询。建议引入"KB 共享索引 + kb_id 路由"模式(详见 §8 优化建议)。
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:587-633
|
||||
def get_cluster_stats(self):
|
||||
"""
|
||||
暴露 store_size / docs / nodes_version / jvm_heap_used 等用于 dashboard
|
||||
"""
|
||||
raw_stats = self.es.cluster.stats()
|
||||
return {...}
|
||||
```
|
||||
|
||||
> **建议**:在调度器里定时拉取 `get_cluster_stats()`,把 `store_size / docs / heap_used_percent` 接入告警。
|
||||
|
||||
### 7.4 慢查询排查
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:250-263
|
||||
logger.debug(f"ESConnection.search {str(indexNames)} query: " + json.dumps(q))
|
||||
res = self.es.search(index=indexNames, body=q, timeout="600s",
|
||||
# search_type="dfs_query_then_fetch",
|
||||
track_total_hits=True, _source=True)
|
||||
```
|
||||
|
||||
排查路径:
|
||||
|
||||
1. **打开 debug 日志**:`logger=rag.es_conn` 调到 DEBUG,可以看到完整 DSL。
|
||||
2. **关闭 `track_total_hits=True`**:超过 10000 hits 时它会真正扫表,对大 KB 是常见慢点;如果不需要精确总数,改为 `track_total_hits=10000`。
|
||||
3. **打开 `dfs_query_then_fetch`**:在多 shard 时让 IDF 全局计算,对相关性更准;代价是一次 RTT。
|
||||
4. **限制 `num_candidates`**:HNSW 阶段候选数大幅影响延迟;已是 `topn * 2`,进一步压缩到 `topn` 可观察延迟下降。
|
||||
5. **slow log**:在 ES 集群层面打开 `index.search.slowlog.threshold.query.warn: 1s`,定位单查询慢点。
|
||||
|
||||
### 7.5 健康监控接口
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/es_conn.py:95-98
|
||||
def health(self) -> dict:
|
||||
health_dict = dict(self.es.cluster.health())
|
||||
health_dict["type"] = "elasticsearch"
|
||||
return health_dict
|
||||
```
|
||||
|
||||
```python
|
||||
# api/app/core/rag/utils/doc_store_conn.py:140-145
|
||||
@abstractmethod
|
||||
def health(self) -> dict:
|
||||
"""Return the health status of the database."""
|
||||
```
|
||||
|
||||
接入业务监控的最简方法:起一个轻量 endpoint 调用 `docStoreConn.health()`,把 `status (green/yellow/red)`、`number_of_nodes`、`active_shards_percent_as_number` 上报。
|
||||
|
||||
---
|
||||
|
||||
## 八、边界条件与已知限制
|
||||
|
||||
| 限制 | 影响 | 解决方向 |
|
||||
| --- | --- | --- |
|
||||
| 路径 B `dims = len(embeddings[0])` 锁定维度 | 换 embedding 模型必须重建索引 | 按维度后缀命名向量字段(参考路径 A 的 `q_{dim}_vec`)|
|
||||
| 路径 A 默认 0 副本 | 节点宕机即数据丢失 | 修改 `res/mapping.json` `number_of_replicas: 1` |
|
||||
| `ELASTICSEARCH_RETRY_ON_TIMEOUT` 默认未生效 | 网络抖动直接抛错 | bug:bool 与 "true" 字符串比较;需显式 `=true` |
|
||||
| `script_score` 暴力扫描 | 大 KB 延迟高 | 路径 B 升级到 `knn` query(ES 8 原生)|
|
||||
| 路径 B inline mapping 不带 metadata.kb_id | 多 KB 共享索引时无法过滤 | 与路径 A 对齐,引入 `kb_id` keyword |
|
||||
| `update_by_segment` 无并发控制 | 并发更新最后写入胜出 | 走 `delete_by_ids` + `add_chunks` 或显式版本号 |
|
||||
| `add_texts` 不捕获 `BulkIndexError` | 局部失败整批失败 | 增加 try/except + 失败重投队列 |
|
||||
| 一个 workspace 多 KB 共享路径 A 索引 | 单 KB 删除走 delete-by-query,不立即释放磁盘 | 定期 `_forcemerge?only_expunge_deletes=true` |
|
||||
| 路径 B 每 KB 一索引 | 大量 KB 时 cluster state 膨胀 | 改为共享索引 + `kb_id` routing |
|
||||
| `track_total_hits=True` | 大库 search 全表扫描慢 | 默认改为 10000,按需取 max |
|
||||
|
||||

|
||||
|
||||
## 九、监控指标与排错指引
|
||||
|
||||
### 9.1 关键指标
|
||||
|
||||
| 指标 | 来源 | 告警阈值(参考)|
|
||||
| --- | --- | --- |
|
||||
| ES cluster status | `health()` | red 立即告警 |
|
||||
| `active_shards_percent_as_number` | `health()` | < 100% 持续 5min 告警 |
|
||||
| `jvm_heap_used_percent` | `get_cluster_stats()` | > 75% 警告,> 85% 紧急 |
|
||||
| `os_mem_used_percent` | `get_cluster_stats()` | > 90% 警告 |
|
||||
| 写入失败比例 | `ESConnection.insert` 返回的 `res` 列表长度 / 总 chunk 数 | > 1% 告警 |
|
||||
| 单次 search P95 延迟 | 调用方时序日志 | hybrid > 1s 告警 |
|
||||
| `track_total_hits` 命中超过 10k 比例 | search.py 总数 | 频繁触发即扩 shard |
|
||||
|
||||
### 9.2 典型故障与处理
|
||||
|
||||
| 现象 | 可能原因 | 处置 |
|
||||
| --- | --- | --- |
|
||||
| 写入超时 | bulk 太大 / refresh 阻塞 | 减小 batch(≤ 1000)/ 写入窗口 `refresh_interval=30s` |
|
||||
| 检索召回为 0 | min_match 过严 / kb_id 过滤不一致 | 看 search.py:447 fallback 是否触发;核对 kb_id |
|
||||
| HNSW 召回率低 | num_candidates 过小 | 增大到 `4 * topn` 或 `topn * 4` |
|
||||
| 维度不匹配报错 | 换 embedding 模型未 reindex | 按 §8 维度限制处理;或在路径 B 删 KB 重建 |
|
||||
| cluster state 过大 | KB 索引数过多 | §10 改造为共享索引 + kb_id routing |
|
||||
| 中文检索召回差 | 写入 analyzer 与查询 analyzer 不一致 | 路径 B 必须保持 `ik_max_word`(写入与查询)|
|
||||
|
||||

|
||||
|
||||
## 十、优化建议与未来扩展点
|
||||
|
||||
### 10.1 架构改造(短期,1-2 个迭代)
|
||||
|
||||
1. **统一双路径**:保留路径 A 抽象 (`DocStoreConnection` + `Dealer`),把路径 B 的 `ElasticSearchVector` 重构为 `DocStoreConnection` 的薄封装,删除重复的连接管理 (`ElasticSearchVectorFactory`),全局只用 `@singleton ESConnection`。
|
||||
2. **修复默认配置**:
|
||||
- `mapping.json` `number_of_replicas: 0 → 1`;
|
||||
- 修正 `ELASTICSEARCH_RETRY_ON_TIMEOUT` bool/str 比较;
|
||||
- 路径 B 的 `script_score` 切换为 `knn` query;
|
||||
- 路径 B mapping 加上 `kb_id` keyword 字段,为后续合并索引铺路。
|
||||
3. **共享索引 + 路由**:把 `Vector_index_{kb_id}_Node` 改为 `kb_chunks_{workspace_id}` 共享索引,`kb_id` 字段做 routing key,索引数从 N(KB) 降到 N(workspace)。
|
||||
|
||||
### 10.2 检索增强(中期)
|
||||
|
||||
1. **真正的 RRF**(reciprocal rank fusion):当前 `weighted_sum` 对分数尺度敏感,引入 `rank_fusion` (ES 8.8+) 或在应用层实现 `rrf_score(d) = Σ 1/(k + rank_i(d))`,对尺度不敏感。
|
||||
2. **稀疏向量(ELSER / SPLADE)**:路径 A 已在 `MatchSparseExpr` 接口预留位置,但 ES 实现未启用 `rank_features` 稀疏检索,引入后可在中文长尾查询上显著提升召回。
|
||||
3. **多模态检索**:路径 B 已感知 `is_multimodal_embedding`(`elasticsearch_vector.py:41`),但只针对火山引擎;引入跨模态 BGE-M3 类模型后,可在同一 dense_vector 字段上做"图文混排"。
|
||||
4. **HNSW 参数显式化**:`mapping.json` 没有指定 `index_options`(m / ef_construction)。在构建大索引时显式 `m=16, ef_construction=200` 可显著提升召回率。
|
||||
|
||||
### 10.3 工程鲁棒性(中期)
|
||||
|
||||
1. **写入幂等保护**:路径 B `add_texts` 不传 `_id`,依赖 `metadata.doc_id` 后查;改为直接用 `doc_id` 作为 `_id`,写入即可幂等,省去后查。
|
||||
2. **变更检测 reindex**:当 mapping 变化时,加一个 `migration_version` 字段触发 alias-swap reindex(`old_index → new_index`),避免线上停机重建。
|
||||
3. **批量限流**:`helpers.bulk` 默认无背压,引入 `chunk_size=500, max_chunk_bytes=10MB` 显式限制,避免大 chunk 撑爆 ES heap。
|
||||
4. **路径 A 的 `ATTEMPT_TIME=2`** 太少:网络抖动 2 次重试后丢错,建议升到 3-5 次,配合指数退避。
|
||||
|
||||
### 10.4 长期扩展点
|
||||
|
||||
1. **冷热分离**:超过半年/低访问的 chunk 迁到冷节点(warm tier)+ rollover index,配合"记忆遗忘引擎" (Memory Forgetting Engine, README §4) 协同。
|
||||
2. **跨集群联邦**:当多 workspace 数据量过大,引入 cross-cluster search(CCS)按 workspace 切集群。
|
||||
3. **GraphRAG 与 VDB 联合检索**:当前 `kg_retriever.retrieval` 在路径 B 是后置 insert(node.py:286-298),可改为"先图谱召回相关实体 → 把实体名作为 `important_kwd^30` 注入 BM25"实现一次 ES 调用同时享受图谱与向量。

|

## 十二、TL;DR(一段话总结)
|
||||
|
||||
MemoryBear 用 Elasticsearch 8 同时承担**全文(Lucene + IK + 自定义 BM25)和向量(dense_vector + HNSW)**双引擎,所以选 ES 而不是专用向量库。代码里有**两套并行路径**:路径 A `ESConnection`(单例 `DocStoreConnection`,多字段动态模板,配 `Dealer` 做 `weighted_sum=0.05,0.95` 的应用层加权 + ES 原生 hybrid 与 rank_features,主要给 GraphRAG/复杂 RAG 用);路径 B `ElasticSearchVector`(`BaseVector` 简化封装,`script_score+cosine` 与 `match+ik_max_word`,主要给工作流知识节点和 KB 服务用,hybrid 走"双路并发 → metadata.doc_id 去重 → 可选 reranker")。索引按 workspace 或按 KB 隔离,`mapping.json` 默认 2 shards / 0 副本 / 1s refresh,向量字段按维度后缀(512/768/1024/1536)动态创建,文本字段以 `_tks/_ltks/_kwd` 后缀套用 dynamic_templates。生产化的主要风险点:路径 B 锁死 dims、默认 0 副本、`ELASTICSEARCH_RETRY_ON_TIMEOUT` 比较 bug、`script_score` 暴力扫描、KB 索引数膨胀;优化方向是合并双路径、改用 `knn` + RRF、共享索引 + `kb_id` routing、配合 GraphRAG 做联合检索。

|
||||
|
||||
## 1. 一句话定位
|
||||
|
||||
GraphRAG 是 MemoryBear 知识库系统的**知识图谱增强检索模块**,通过 LLM 从文档中抽取实体-关系三元组构建知识图谱,在检索阶段利用图谱结构(实体关联、社区报告、多跳路径)补充传统向量检索的语义盲区,实现"结构化知识 + 语义向量"的混合召回。
|
||||
|
||||
---
|
||||
|
||||
## 2. 设计目标与适用场景
|
||||
|
||||
### 2.1 设计目标
|
||||
|
||||
1. **结构化知识补充**:向量检索擅长语义匹配,但对"多跳推理""实体关系推导""全局摘要"等场景覆盖不足。GraphRAG 通过显式构建实体关系图谱填补这一 gap。
|
||||
2. **两种精度-成本档位**:
|
||||
- **Light 模式**(默认):基于 LightRAG 思路,轻量快速,适合对延迟敏感、文档规模中等的场景。
|
||||
- **General 模式**(完整版):基于 Microsoft GraphRAG,支持实体消歧、社区发现、社区报告生成,适合需要深度分析、复杂推理的场景。
|
||||
3. **与现有基础设施复用**:不引入 Neo4j 等独立图数据库,复用 Elasticsearch 作为图谱存储,降低运维复杂度。
|
||||
|
||||
### 2.2 适用场景
|
||||
|
||||
| 场景 | 推荐模式 | 原因 |
|
||||
|---|---|---|
|
||||
| 快速知识问答,文档 < 1K | Light | 建图快、成本低 |
|
||||
| 企业级知识库,文档 > 10K | General | 实体消歧 + 社区报告提供全局洞察 |
|
||||
| 需要跨文档实体关联分析 | General | 实体消歧合并跨文档同名实体 |
|
||||
| 需要"某实体的全局影响力"评估 | General | 社区报告 + PageRank 提供全局视角 |
|
||||
| 实时对话/低延迟检索 | Light | General 的社区报告生成耗时高 |
|
||||
|
||||

|
||||
|
||||
## 3. 关键概念与术语表
|
||||
|
||||
| 术语 | 定义 |
|
||||
|---|---|
|
||||
| **Entity(实体)** | 从文本中抽取的命名对象,如人名、组织、地点。在代码中存储为图的节点。 |
|
||||
| **Relationship(关系)** | 实体之间的语义关联,如"A 是 B 的 CEO"。存储为图的边。 |
|
||||
| **Subgraph(子图)** | 单个文档抽取出的局部知识图谱,最终合并为全局图谱。 |
|
||||
| **Entity Resolution(实体消歧)** | 识别图谱中不同名称但指向同一实体的节点,将其合并(如 "Apple Inc." vs "Apple")。 |
|
||||
| **Community(社区)** | 图谱中高密度连接的节点簇,通过 Leiden 算法发现。 |
|
||||
| **Community Report(社区报告)** | 对单个社区的 LLM 生成的结构化摘要报告,含标题、摘要、影响力评级、关键发现。 |
|
||||
| **PageRank** | 用于衡量实体在图谱中的重要程度,检索时作为排序因子之一。 |
|
||||
| **N-hop Path** | 从查询实体出发,沿图谱边行走 N 步可达的实体路径,用于扩展召回。 |
|
||||
| **Tuple Delimiter** | 实体/关系抽取输出中的字段分隔符,代码中为 `<\|>`。 |
|
||||
| **Record Delimiter** | 抽取输出中多条记录的分隔符,代码中为 `##`。 |
|
||||
| **knowledge_graph_kwd** | ES 文档中的类型标记字段,取值:`entity` / `relation` / `graph` / `subgraph` / `community_report` / `ty2ents`。 |

## 5. 关键源码详解
|
||||
|
||||
### 5.1 图谱构建链路
|
||||
|
||||
#### 5.1.1 建图总控入口
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/index.py:36-119`
|
||||
|
||||
```python
|
||||
async def run_graphrag(
|
||||
row: dict, language, with_resolution: bool, with_community: bool,
|
||||
chat_model, embedding_model, callback,
|
||||
):
|
||||
# 选择抽取器:LightKGExt(默认)或 GeneralKGExt
|
||||
extractor = LightKGExt if method != "general" else GeneralKGExt
|
||||
subgraph = await generate_subgraph(extractor, workspace_id, kb_id, document_id, chunks, ...)
|
||||
new_graph = await merge_subgraph(workspace_id, kb_id, document_id, subgraph, embedding_model, callback)
|
||||
if with_resolution:
|
||||
await resolve_entities(new_graph, subgraph_nodes, ...)
|
||||
if with_community:
|
||||
await extract_community(new_graph, ...)
|
||||
```
|
||||
|
||||
**设计要点**:
|
||||
- `parser_config["graphrag"]["method"]` 控制 Light/General 切换(`"general"` 为 General,其他为 Light)。
|
||||
- `with_resolution` 和 `with_community` 为独立开关,仅在 General 模式下有意义(Light 不支持)。
|
||||
- 使用 `RedisDistributedLock` 保证同一 KB 的并发建图安全。
|
||||
|
||||
#### 5.1.2 子图生成
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/index.py:333-406`
|
||||
|
||||
```python
|
||||
async def generate_subgraph(extractor, workspace_id, kb_id, document_id, chunks, ...):
|
||||
# 幂等检查:如果 document_id 已在图中,跳过
|
||||
contains = await does_graph_contains(workspace_id, kb_id, document_id)
|
||||
if contains:
|
||||
return None
|
||||
ext = extractor(llm_bdl, language=language, entity_types=entity_types)
|
||||
ents, rels = await ext(document_id, chunks, callback, task_id=task_id)
|
||||
subgraph = nx.Graph()
|
||||
for ent in ents:
|
||||
subgraph.add_node(ent["entity_name"], **ent)
|
||||
for rel in rels:
|
||||
if subgraph.has_node(rel["src_id"]) and subgraph.has_node(rel["tgt_id"]):
|
||||
subgraph.add_edge(rel["src_id"], rel["tgt_id"], **rel)
|
||||
tidy_graph(subgraph, callback, check_attribute=False)
|
||||
# 写入 ES 作为 subgraph 类型文档
|
||||
await trio.to_thread.run_sync(settings.docStoreConn.insert, [chunk], ...)
|
||||
return subgraph
|
||||
```
|
||||
|
||||
**关键设计**:
|
||||
- `does_graph_contains()` 通过查询 `knowledge_graph_kwd="graph"` 的 `source_id` 字段实现幂等性。
|
||||
- `tidy_graph()` 清理无 description/source_id 的脏节点/边。
|
||||
- 每个文档的 subgraph 独立存储,便于增量更新和重建。
|
||||
|
||||
#### 5.1.3 实体/关系抽取(Light vs General)
|
||||
|
||||
**Light 版抽取器**
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/light/graph_extractor.py:31-132`
|
||||
|
||||
```python
|
||||
class GraphExtractor(Extractor):
|
||||
def __init__(self, llm_invoker, language="English", entity_types=None,
|
||||
example_number=2, max_gleanings=None):
|
||||
# 使用 LightRAG 风格的 Prompt
|
||||
self._entity_extract_prompt = PROMPTS["entity_extraction"]
|
||||
self._continue_prompt = PROMPTS["entity_continue_extraction"]
|
||||
self._if_loop_prompt = PROMPTS["entity_if_loop_extraction"]
|
||||
# 预留 60% token 给输入文本
|
||||
self._left_token_count = max(getattr(llm_invoker, 'max_length', 8096) * 0.6, ...)
|
||||
|
||||
async def _process_single_content(self, chunk_key_dp, chunk_seq, num_chunks, out_results, task_id=""):
|
||||
hint_prompt = self._entity_extract_prompt.format(**self._context_base, input_text=content)
|
||||
# 首轮抽取
|
||||
final_result = await trio.to_thread.run_sync(self._chat, "", [{"role": "user", "content": hint_prompt}], {}, task_id)
|
||||
# 多轮 gleaning:追问"还有遗漏吗?"
|
||||
for now_glean_index in range(self._max_gleanings):
|
||||
glean_result = await trio.to_thread.run_sync(self._chat, "", history, gen_conf, task_id)
|
||||
final_result += glean_result
|
||||
# 用 if_loop_prompt 判断是否继续
|
||||
if_loop_result = await trio.to_thread.run_sync(self._chat, "", history, gen_conf, task_id)
|
||||
if if_loop_result.strip().lower() != "yes":
|
||||
break
|
||||
```
|
||||
|
||||
**General 版抽取器**
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/graph_extractor.py:34-151`
|
||||
|
||||
```python
|
||||
class GraphExtractor(Extractor):
|
||||
def __init__(self, llm_invoker, language="English", entity_types=None, ...):
|
||||
self._extraction_prompt = GRAPH_EXTRACTION_PROMPT
|
||||
self._max_gleanings = max_gleanings or ENTITY_EXTRACTION_MAX_GLEANINGS
|
||||
# 使用 tiktoken 构造 logit_bias 强制输出 YES/NO
|
||||
encoding = tiktoken.get_encoding("cl100k_base")
|
||||
yes = encoding.encode("YES")
|
||||
no = encoding.encode("NO")
|
||||
self._loop_args = {"logit_bias": {yes[0]: 100, no[0]: 100}, "max_tokens": 1}
|
||||
|
||||
async def _process_single_content(self, chunk_key_dp, chunk_seq, num_chunks, out_results, task_id=""):
|
||||
# 类似 Light,但使用 CONTINUE_PROMPT + LOOP_PROMPT
|
||||
for i in range(self._max_gleanings):
|
||||
history.append({"role": "user", "content": CONTINUE_PROMPT})
|
||||
response = await trio.to_thread.run_sync(lambda: self._chat("", history, {}))
|
||||
if i >= self._max_gleanings - 1:
|
||||
break
|
||||
history.append({"role": "assistant", "content": response})
|
||||
history.append({"role": "user", "content": LOOP_PROMPT})
|
||||
continuation = await trio.to_thread.run_sync(lambda: self._chat("", history))
|
||||
if continuation != "Y":
|
||||
break
|
||||
```
|
||||
|
||||
**Light vs General 抽取差异**:
|
||||
|
||||
| 维度 | Light | General |
|
||||
|---|---|---|
|
||||
| Prompt 风格 | LightRAG(更详细的示例 + content_keywords) | MS GraphRAG(简洁 + 无 keywords) |
|
||||
| Gleaning 终止 | 自然语言判断 `"yes"/"no"` | 强制单字 `"Y"`(logit_bias) |
|
||||
| 示例数量 | 默认 3 个,可调 `example_number` | 固定 3 个 |
|
||||
| 输出格式 | 含 `content_keywords` 元组 | 仅 entity + relationship |
|
||||
|
||||
#### 5.1.4 节点/边合并与摘要
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/extractor.py:205-300`
|
||||
|
||||
```python
|
||||
async def _merge_nodes(self, entity_name, entities, all_relationships_data, task_id=""):
|
||||
# 投票决定实体类型(出现次数最多者)
|
||||
entity_type = sorted(Counter([dp["entity_type"] for dp in entities]).items(), key=lambda x: x[1], reverse=True)[0][0]
|
||||
# 去重合并所有描述
|
||||
description = GRAPH_FIELD_SEP.join(sorted(set([dp["description"] for dp in entities])))
|
||||
# LLM 摘要(描述超过 12 条时触发)
|
||||
description = await self._handle_entity_relation_summary(entity_name, description, task_id=task_id)
|
||||
node_data = dict(entity_type=entity_type, description=description, source_id=already_source_ids)
|
||||
all_relationships_data.append(node_data)
|
||||
|
||||
async def _handle_entity_relation_summary(self, entity_or_relation_name, description, task_id=""):
|
||||
description_list = use_description.split(GRAPH_FIELD_SEP)
|
||||
if len(description_list) <= 12:
|
||||
return use_description # 描述较少时不摘要
|
||||
# 触发 LLM 摘要
|
||||
async with chat_limiter:
|
||||
summary = await trio.to_thread.run_sync(self._chat, "", [{"role": "user", "content": use_prompt}], {}, task_id)
|
||||
return summary
|
||||
```
|
||||
|
||||
**设计要点**:
|
||||
- 同一实体名在不同 chunk 中的描述用 `<SEP>` 拼接,超过 12 条触发 LLM 摘要,防止描述无限膨胀。
|
||||
- 关系合并同理:权重累加、关键词去重并集、描述拼接摘要。
|
||||
|
||||
#### 5.1.5 子图合并到全局图
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/utils.py:199-229`
|
||||
|
||||
```python
|
||||

|
||||
"""Merge graph g2 into g1 in place."""
|
||||

|
||||
change.added_updated_nodes.add(node_name)
|
||||
if not g1.has_node(node_name):
|
||||
g1.add_node(node_name, **attr)
|
||||
continue
|
||||
# 已存在:描述追加、source_id 合并
|
||||
node = g1.nodes[node_name]
|
||||
node["description"] += GRAPH_FIELD_SEP + attr["description"]
|
||||
node["source_id"] += attr["source_id"]
|
||||
|
||||
for source, target, attr in g2.edges(data=True):
|
||||
change.added_updated_edges.add(get_from_to(source, target))
|
||||
edge = g1.get_edge_data(source, target)
|
||||
if edge is None:
|
||||
g1.add_edge(source, target, **attr)
|
||||
continue
|
||||
# 已存在:权重累加、描述追加
|
||||
edge["weight"] += attr.get("weight", 0)
|
||||
edge["description"] += GRAPH_FIELD_SEP + attr["description"]
|
||||
edge["keywords"] += attr["keywords"]
|
||||
edge["source_id"] += attr["source_id"]
|
||||
|
||||
# 更新度中心性(rank)
|
||||
for node_degree in g1.degree:
|
||||
g1.nodes[str(node_degree[0])]["rank"] = int(node_degree[1])
|
||||
```
|
||||
|
||||
#### 5.1.6 实体消歧
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/entity_resolution.py:31-141`
|
||||
|
||||
```python
|
||||
class EntityResolution(Extractor):
|
||||
async def __call__(self, graph, subgraph_nodes, prompt_variables=None, callback=None, task_id=""):
|
||||
# 1. 按 entity_type 分组
|
||||
node_clusters = {entity_type: [] for entity_type in entity_types}
|
||||
for node in nodes:
|
||||
node_clusters[graph.nodes[node].get('entity_type', '-')].append(node)
|
||||
|
||||
# 2. 生成候选对(组合数限制 + 编辑距离预筛选)
|
||||
for k, v in node_clusters.items():
|
||||
candidate_resolution[k] = [(a, b) for a, b in itertools.combinations(v, 2)
|
||||
if (a in subgraph_nodes or b in subgraph_nodes) and self.is_similarity(a, b)]
|

# 3. LLM 批量判断(batch=100,并发=5,trio 协程)
|
||||

||||
# 4. 合并连通分量
|
||||

merging_nodes = list(sub_connect_graph)
|
||||
await self._merge_graph_nodes(graph, merging_nodes, change, task_id)
|
||||
|
||||
# 5. 重新计算 PageRank
|
||||
pr = nx.pagerank(graph)
|
||||
```
|
||||
|
||||
**编辑距离预筛选算法**(`is_similarity`,第 225-239 行):
|
||||
|
||||
```python
|
||||
def is_similarity(self, a, b):
|
||||
# 规则1:2-gram 差异中不能包含数字(避免 "Product 1" vs "Product 2" 被误判)
|
||||
if self._has_digit_in_2gram_diff(a, b):
|
||||
return False
|
||||
# 规则2:英文用 editdistance,阈值 = min(len(a), len(b)) // 2
|
||||
if is_english(a) and is_english(b):
|
||||
return editdistance.eval(a, b) <= min(len(a), len(b)) // 2
|
||||
# 规则3:中文/混合文本用字符集 Jaccard 相似度,阈值 0.8
|
||||
a, b = set(a), set(b)
|
||||
max_l = max(len(a), len(b))
|
||||
if max_l < 4:
|
||||
return len(a & b) > 1
|
||||
return len(a & b) * 1. / max_l >= 0.8
|
||||
```
|
||||
|
||||
**消歧流程设计意图**:
|
||||
1. **预筛选**:编辑距离过滤掉明显不同的实体对,减少 LLM 调用量(组合数从 O(n²) 降到可控范围)。
|
||||
2. **批量 LLM 判断**:每批 100 对,并发 5 个请求,timeout 280s(测试环境)或无限(生产环境)。
|
||||
3. **连通分量合并**:LLM 判定"A=B"和"B=C"后,即使 LLM 没直接判断"A=C",通过连通分量也会将 A、B、C 合并。
|
||||
4. **任务取消支持**:每步检查 `has_canceled(task_id)`,支持用户中断长时任务。
|
||||

||||
#### 5.1.7 社区发现与报告生成

ents_from_query = self.get_relevant_ents_by_keywords(ents, filters, idxnms, kb_ids, emb_mdl, ent_sim_threshold)
|
||||
ents_from_types = self.get_relevant_ents_by_types(ty_kwds, filters, idxnms, kb_ids, 10000)
|
||||
rels_from_txt = self.get_relevant_relations_by_txt(qst, filters, idxnms, kb_ids, emb_mdl, rel_sim_threshold)
|
||||
# Step 3: n-hop 路径扩展
|
||||
nhop_pathes = defaultdict(dict)
|
||||
for _, ent in ents_from_query.items():
|
||||
for nbr in ent.get("n_hop_ents", []):
|
||||
for i in range(len(path) - 1):
|
||||
nhop_pathes[(path[i], path[i+1])]["sim"] += ent["sim"] / (2 + i)
|
||||
# Step 4: 融合打分
|
||||
for ent in ents_from_types:
|
||||
if ent in ents_from_query:
|
||||
ents_from_query[ent]["sim"] *= 2 # 类型匹配 boost
|
||||
for (f, t) in rels_from_txt:
|
||||
s = nhop_pathes.get(pair, {}).get("sim", 0)
|
||||
if f in ents_from_types: s += 1
|
||||
if t in ents_from_types: s += 1
|
||||
rels_from_txt[(f, t)]["sim"] *= s + 1 # n-hop + 类型 boost
|
||||
# Step 5: 排序截断
|
||||
ents_from_query = sorted(..., key=lambda x: x[1]["sim"] * x[1]["pagerank"], reverse=True)[:ent_topn]
|
||||
rels_from_txt = sorted(..., key=lambda x: x[1]["sim"] * x[1]["pagerank"], reverse=True)[:rel_topn]
|
||||
# Step 6: 社区报告召回
|
||||
community = self._community_retrieval_([n for n, _ in ents_from_query], filters, kb_ids, idxnms, comm_topn, max_token)
|
||||
return {"page_content": ents + relas + community, "vector": None, ...}
|
||||
```
|
||||
|
||||
#### 5.2.2 Query 改写
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/search.py:33-55`
|
||||
|
||||
```python
|
||||
def query_rewrite(self, llm, question, idxnms, kb_ids):
|
||||
# 从 ES 获取当前 KB 的实体类型池
|
||||
ty2ents = trio.run(lambda: get_entity_type2samples(idxnms, kb_ids))
|
||||
hint_prompt = PROMPTS["minirag_query2kwd"].format(
|
||||
query=question,
|
||||
TYPE_POOL=json.dumps(ty2ents, ensure_ascii=False, indent=2))
|
||||
result = self._chat(llm, hint_prompt, [{"role": "user", "content": "Output:"}], {})
|
||||
keywords_data = json_repair.loads(result)
|
||||
type_keywords = keywords_data.get("answer_type_keywords", [])
|
||||
entities_from_query = keywords_data.get("entities_from_query", [])[:5]
|
||||
return type_keywords, entities_from_query
|
||||
```
|
||||
|
||||
**设计意图**:
|
||||
- Query 改写将自然语言问题转换为两种结构化信号:
|
||||
1. `answer_type_keywords`:回答类型(如 "ORGANIZATION", "PERSON"),用于类型过滤召回。
|
||||
2. `entities_from_query`:查询中的具体实体,用于向量相似度召回。
|
||||
- 类型池 `ty2ents` 从 ES 中已建图谱的实体类型采样而来,保证类型建议与当前知识库实际类型一致。
|
||||
|
||||
#### 5.2.3 实体向量召回
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/search.py:96-106`
|
||||
|
||||
```python
|
||||
def get_relevant_ents_by_keywords(self, keywords, filters, idxnms, kb_ids, emb_mdl, sim_thr=0.3, N=56):
|
||||
filters["knowledge_graph_kwd"] = "entity"
|
||||
matchDense = self.get_vector(", ".join(keywords), emb_mdl, 1024, sim_thr)
|
||||
es_res = self.dataStore.search(
|
||||
["page_content", "entity_kwd", "rank_flt"], [], filters, [matchDense],
|
||||
OrderByExpr(), 0, N, idxnms, kb_ids)
|
||||
return self._ent_info_from_(es_res, sim_thr)
|
||||
```
|
||||
|
||||
**设计要点**:
|
||||
- 实体和关系都以独立 chunk 形式存储在 ES 中,附带 dense_vector 字段。
|
||||
- 向量维度由 embedding model 决定,存储字段名为 `q_{dim}_vec`。
|
||||
- `sim_thr=0.3` 为默认相似度阈值,过滤低质量匹配。
|
||||
|
||||
#### 5.2.4 n-hop 路径扩展与融合公式
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/search.py:160-210`
|
||||
|
||||
```python
|
||||
# n-hop 路径:从命中实体出发,沿预计算的邻居路径扩展
|
||||
for _, ent in ents_from_query.items():
|
||||
nhops = ent.get("n_hop_ents", [])
|
||||
for nbr in nhops:
|
||||
path = nbr["path"]
|
||||
wts = nbr["weights"]
|
||||
for i in range(len(path) - 1):
|
||||
f, t = path[i], path[i + 1]
|
||||
if (f, t) in nhop_pathes:
|
||||
nhop_pathes[(f, t)]["sim"] += ent["sim"] / (2 + i)
|
||||
else:
|
||||
nhop_pathes[(f, t)]["sim"] = ent["sim"] / (2 + i)
|
||||
nhop_pathes[(f, t)]["pagerank"] = wts[i]
|
||||
|
||||
# 融合公式:P(E|Q) ≈ P(E) * P(Q|E) → pagerank * sim
|
||||
# 实体排序:score = sim × pagerank
|
||||
ents_from_query = sorted(ents_from_query.items(),
|
||||
key=lambda x: x[1]["sim"] * x[1]["pagerank"], reverse=True)[:ent_topn]
|
||||
```
|
||||
|
||||
**设计意图**:
|
||||
- n-hop 路径在实体入库时预计算(通过 NetworkX 邻居遍历),存储在 `n_hop_with_weight` 字段。
|
||||
- 距离越远的 hop,贡献权重按 `1/(2+i)` 衰减(1-hop: 1/3, 2-hop: 1/4...)。
|
||||
- 最终排序融合了两个信号:向量相似度(P(Q|E),查询与实体的语义匹配)和 PageRank(P(E),实体在全局图谱中的重要性)。
|
||||
|
||||
#### 5.2.5 与向量检索的协同
|
||||
|
||||
GraphRAG 检索**不替代**向量检索,而是作为**并行的召回源**之一。在 `settings.py` 中:
|
||||
|
||||
```python
|
||||
kg_retriever = kg_search.KGSearch(docStoreConn) # 图谱检索器
|
||||
retriever = search.Dealer(docStoreConn) # 向量检索器
|
||||
```
|
||||
|
||||
上层调用方(如对话工作流)会同时调用两者,将图谱召回结果(Entities + Relations + Community Reports)与向量召回的 Document Chunks 一起送入 LLM 上下文。

## 6. Light vs General 差异详解
|
||||
|
||||
### 6.1 功能对比
|
||||
|
||||
| 维度 | Light | General | 说明 |
|
||||
|---|---|---|---|
|
||||
| **实体抽取 Prompt** | LightRAG 风格,含 content_keywords | MS GraphRAG 风格,更简洁 | `light/graph_prompt.py` vs `general/graph_prompt.py` |
|
||||
| **Gleaning 终止** | 自然语言 yes/no | 强制单字 Y(logit_bias) | Light 更灵活,General 更确定 |
|
||||
| **实体消歧** | ❌ 不支持 | ✅ 支持 | `entity_resolution.py` 仅在 General 流程中调用 |
|
||||
| **社区发现** | ❌ 不支持 | ✅ Leiden 算法 | `general/leiden.py` |
|
||||
| **社区报告** | ❌ 不支持 | ✅ LLM 生成报告 | `general/community_reports_extractor.py` |
|
||||
| **实体嵌入** | 仅实体名向量 | 支持 Node2Vec(备用) | `general/entity_embedding.py` 当前未在主线使用 |
|
||||
| **思维导图** | ❌ 不支持 | ✅ 支持 | `general/mind_map_extractor.py` |
|
||||
| **并发控制** | 相同 | 相同 | `trio.Semaphore` + `chat_limiter` |
|
||||
| **建图耗时** | 低(无消歧/社区) | 高(消歧 + 社区报告 ≈ 额外 10-30 分钟) | |
|
||||
| **Token 消耗** | 低 | 高(社区报告每社区一次 LLM 调用) | |
|
||||
| **适用数据规模** | < 1K 文档 | > 1K 文档 | |
|
||||
|
||||
### 6.2 切换条件
|
||||
|
||||
**配置入口**:`parser_config["graphrag"]["method"]`
|
||||
|
||||
```python
|
||||
# api/app/core/rag/graphrag/general/index.py:54
|
||||
extractor = LightKGExt if (
|
||||
"method" not in row["parser_config"].get("graphrag", {})
|
||||
or row["parser_config"]["graphrag"]["method"] != "general"
|
||||
) else GeneralKGExt
|
||||
```
|
||||
|
||||
| 条件 | 推荐模式 |
|
||||
|---|---|
|
||||
| `parser_config.graphrag.method` 未设置 或 != `"general"` | **Light**(默认) |
|
||||
| `parser_config.graphrag.method == "general"` | **General** |
|
||||
| `with_resolution=True` 且 method=general | General + 实体消歧 |
|
||||
| `with_community=True` 且 method=general | General + 社区报告 |
|
||||
|
||||
### 6.3 资源消耗对比(估算)
|
||||
|
||||
以 1000 个 chunk(约 50 万字)的知识库为例:
|
||||
|
||||
| 阶段 | Light | General | 差异原因 |
|
||||
|---|---|---|---|
|
||||
| 实体抽取 | ~100 次 LLM 调用 | ~100 次 LLM 调用 | 两者类似 |
|
||||
| 实体消歧 | 0 | ~10-50 次 LLM 调用 | 候选对数量取决于实体重复率 |
|
||||
| 社区报告 | 0 | ~20-100 次 LLM 调用 | 社区数量取决于图密度 |
|
||||
| 总 Token | ~500K-1M | ~2M-5M | General 多轮摘要 + 社区报告 |
|
||||
| 总时间 | ~5-15 分钟 | ~30-60 分钟 | 消歧和社区是主要耗时 |
|
||||
| ES 存储 | ~实体数 + 关系数 | + 社区报告数 + 全局图 | |

## 7. 关键 Prompt 解读
|
||||
|
||||
### 7.1 Query 分析 Prompt:`minirag_query2kwd`
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/query_analyze_prompt.py:9-155`
|
||||
|
||||
```
|
||||
---Role---
|
||||
You are a helpful assistant tasked with identifying both answer-type and low-level keywords...
|
||||
|
||||
---Goal---
|
||||
Given the query, list both answer-type and low-level keywords.
|
||||
answer_type_keywords focus on the type of the answer...
|
||||
The answer_type_keywords must be selected from Answer type pool.
|
||||
|
||||
---Instructions---
|
||||
- Output the keywords in JSON format.
|
||||
- "answer_type_keywords" for the types of the answer... No more than 3.
|
||||
- "entities_from_query" for specific entities or details.
|
||||
```
|
||||
|
||||
**设计意图逐行解读**:
|
||||
|
||||
| Prompt 片段 | 设计意图 |
|
||||
|---|---|
|
||||
| `answer_type_keywords must be selected from Answer type pool` | 强制从知识库实际存在的类型中选择,避免 LLM 编造不存在的类型。类型池从已建图谱采样,保证类型有效性。 |
|
||||
| `No more than 3` | 限制类型数量,防止过度发散导致召回噪声。 |
|
||||
| `entities_from_query must be extracted from the query` | 强调实体必须从查询原文提取,禁止 LLM 扩展或推测,保证召回精确性。 |
|
||||
| 4 个覆盖不同领域的示例 | Few-shot 示例涵盖时间、地点、组织、抽象概念,帮助 LLM 理解类型判定逻辑。 |
|
||||
| `TYPE_POOL` 动态注入 | 运行时从 ES 查询当前 KB 的实体类型分布,使类型建议与知识库内容一致。 |
|
||||
|
||||
### 7.2 实体消歧 Prompt:`ENTITY_RESOLUTION_PROMPT`
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/entity_resolution_prompt.py:1-58`
|
||||
|
||||
```
|
||||
-Goal-
|
||||
Please answer the following Question as required
|
||||
|
||||
-Steps-
|
||||
1. Identify each line of questioning as required
|
||||
2. Return output in English as a single list of each line answer...
|
||||
Use **{record_delimiter}** as the list delimiter.
|
||||
|
||||
-Examples-
|
||||
Example 1: Product 对比(computer vs phone → No,television vs TV → No)
|
||||
Example 2: Toponym 对比(Chicago vs ChiTown → Yes,Shanghai vs Zhengzhou → No)
|
||||
|
||||
-Real Data-
|
||||
Question:{input_text}
|
||||
```
|
||||
|
||||
**设计意图逐行解读**:
|
||||
|
||||
| Prompt 片段 | 设计意图 |
|
||||
|---|---|
|
||||
| `only focus on critical properties and overlook noisy factors` | 引导 LLM 关注核心语义特征,忽略大小写、缩写、冠词等噪声。 |
|
||||
| `Use domain knowledge of {entity_type}s` | 提示 LLM 利用领域知识辅助判断(如 "Peking" = "Beijing" 在地理领域成立)。 |
|
||||
| `answer the above N questions in the format: For Question i, Yes/No...` | 强制固定输出格式,便于正则解析。 |
|
||||
| `##` record_delimiter + `<\|>` entity_index_delimiter + `&&` resolution_result_delimiter | 三层分隔符设计,降低解析冲突概率。 |
|
||||
| 两个示例分别覆盖产品和地名 | 展示不同领域的消歧标准差异,增强泛化能力。 |
|
||||
|
||||
**注意**:示例中 "television vs TV → No" 和 "Chicago vs ChiTown → Yes" 看起来矛盾,实际上是在**引导 LLM 区分"缩写是否代表同一实体"**——TV 是 television 的缩写(同一事物),但 Prompt 标注为 No,可能是示例错误;而 Chicago vs ChiTown(俚语别称)标注为 Yes。这个示例设计值得商榷,实际效果取决于 LLM 的理解。
|
||||
|
||||
### 7.3 Light 版实体抽取 Prompt
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/light/graph_prompt.py:20-59`
|
||||
|
||||
```
|
||||
---Goal---
|
||||
Given a text document... identify all entities... and all relationships...
|
||||
|
||||
---Steps---
|
||||
1. Identify all entities. Format: ("entity"{tuple_delimiter}<name>{tuple_delimiter}<type>{tuple_delimiter}<description>)
|
||||
2. Identify all relationships. Format: ("relationship"{tuple_delimiter}<src>{tuple_delimiter}<tgt>{tuple_delimiter}<desc>{tuple_delimiter}<keywords>{tuple_delimiter}<strength>)
|
||||
3. Identify high-level key words... Format: ("content_keywords"{tuple_delimiter}<keywords>)
|
||||
4. Return output as a single list...
|
||||
5. When finished, output {completion_delimiter}
|
||||
```
|
||||
|
||||
**设计意图**:
|
||||
- **Tuple 格式**:`("entity"<\|>NAME<\|>TYPE<\|>DESC)` 使用固定分隔符,便于正则提取,比 JSON 更抗格式错误。
|
||||
- **content_keywords**:额外提取文档级关键词,可用于后续检索增强或标签分类。
|
||||
- **relationship_keywords**:关系关键词用于关系 chunk 的文本检索补充。
|
||||
- **strength**:关系强度(1-10)用于后续排序加权。
|
||||
- **多轮 gleaning**:首轮抽取后,用 `"MANY entities were missed"` 追问,最多 2 轮(`ENTITY_EXTRACTION_MAX_GLEANINGS=2`)。
|
||||
|
||||
### 7.4 General 版实体抽取 Prompt
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/graph_prompt.py:8-106`
|
||||
|
||||
与 Light 版的主要差异:
|
||||
- **无 content_keywords**:仅抽取 entity + relationship,更聚焦。
|
||||
- **无 relationship_keywords**:关系描述更简洁。
|
||||
- **无 strength 数值**:关系权重由出现频率决定(非 LLM 评分)。
|
||||
- **LOOP_PROMPT 使用 logit_bias**:强制输出单字 `Y` 或 `N`,比 Light 的自然语言判断更确定。
|
||||
|
||||
### 7.5 社区报告 Prompt
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/general/community_report_prompt.py:8-157`
|
||||
|
||||
```
|
||||
# Goal
|
||||
Write a comprehensive report of a community...
|
||||
|
||||
# Report Structure
|
||||
- TITLE: community's name...
|
||||
- SUMMARY: An executive summary...
|
||||
- IMPACT SEVERITY RATING: a float score between 0-10...
|
||||
- RATING EXPLANATION: single sentence...
|
||||
- DETAILED FINDINGS: 5-10 key insights...
|
||||
|
||||
# Grounding Rules
|
||||
Points supported by data should list their data references as follows:
|
||||
"...supported by multiple data references [Data: <dataset name> (record ids)]"
|
||||
```
|
||||
|
||||
**设计意图**:
|
||||
- **结构化 JSON 输出**:强制 `title/summary/rating/rating_explanation/findings` 五字段,便于程序解析。
|
||||
- **影响力评级(0-10)**:量化社区重要性,检索时按 `weight_flt` 排序优先返回高影响力社区。
|
||||
- **Grounding Rules**:要求引用数据记录 ID,增强可解释性(虽然当前实现未实际利用这些引用)。
|
||||
- **示例输入**:提供 `VERDANT OASIS PLAZA` 和 `HARMONY ASSEMBLY` 的完整示例,展示输出格式和数据引用方式。
|
||||

|
||||
## 8. 图谱存储设计
|
||||
|
||||
### 8.1 不使用 Neo4j
|
||||
|
||||
MemoryBear 的 GraphRAG **不依赖 Neo4j** 等专用图数据库,而是复用 Elasticsearch 作为统一存储。理由:
|
||||
1. **运维简化**:无需维护额外的图数据库集群。
|
||||
2. **混合检索**:实体/关系的向量嵌入与文档 chunk 存储在同一张索引,便于统一检索。
|
||||
3. **增量更新**:ES 的文档模型天然支持增量写入和版本管理。
|
||||
|
||||
### 8.2 ES 文档类型(knowledge_graph_kwd)
|
||||
|
||||
| 类型 | 存储内容 | 关键字段 |
|
||||
|---|---|---|
|
||||
| `graph` | 全局图(NetworkX node_link_data JSON) | `page_content`(JSON)、`source_id` |
|
||||
| `subgraph` | 单文档子图 | `page_content`(JSON)、`source_id` |
|
||||
| `entity` | 单个实体(可向量检索) | `entity_kwd`、`entity_type_kwd`、`rank_flt`、`q_*_vec` |
|
||||
| `relation` | 单个关系(可向量检索) | `from_entity_kwd`、`to_entity_kwd`、`weight_int`、`q_*_vec` |
|
||||
| `community_report` | 社区报告 | `docnm_kwd`(标题)、`weight_flt`、`entities_kwd` |
|
||||
| `ty2ents` | 类型→实体样例映射 | `page_content`(JSON dict) |
|
||||
|
||||
### 8.3 向量嵌入策略
|
||||
|
||||
**文件**: `api/app/core/rag/graphrag/utils.py:301-327`(实体)和 `352-378`(关系)
|
||||
|
||||
```python
|
||||
async def graph_node_to_chunk(kb_id, embd_mdl, ent_name, meta, chunks):
|
||||
chunk = {
|
||||
"entity_kwd": ent_name,
|
||||
"knowledge_graph_kwd": "entity",
|
||||
"entity_type_kwd": meta["entity_type"],
|
||||
"page_content": json.dumps(meta, ensure_ascii=False),
|
||||
...
|
||||
}
|
||||
# 实体向量 = entity_name 的 embedding
|
||||
ebd, _ = embd_mdl.encode([ent_name])
|
||||
chunk["q_%d_vec" % len(ebd)] = ebd
|
||||
|
||||
async def graph_edge_to_chunk(kb_id, embd_mdl, from_ent_name, to_ent_name, meta, chunks):
|
||||
# 关系向量 = "from->to: description" 的 embedding
|
||||
txt = f"{from_ent_name}->{to_ent_name}"
|
||||
ebd, _ = embd_mdl.encode([txt + f": {meta['description']}"])
|
||||
chunk["q_%d_vec" % len(ebd)] = ebd
|
||||
```
|
||||
|
||||
**设计要点**:
|
||||
- 实体向量基于**实体名**(`ent_name`),而非描述文本——因为检索时用户查询通常包含实体名。
|
||||
- 关系向量基于 `"from->to: description"`,兼顾结构信息和语义信息。
|
||||
- 向量缓存:通过 Redis + xxhash 缓存 embedding 结果,避免重复计算。

## 10. 边界条件与已知限制
|
||||
|
||||
### 10.1 已知限制
|
||||
|
||||
| 限制 | 影响 | 缓解措施 |
|
||||
|---|---|---|
|
||||
| 实体消歧仅处理 subgraph_nodes 内的节点 | 历史已消歧的节点不再参与新一轮消歧 | 手动重建图谱触发全量消歧 |
|
||||
| 社区报告忽略 < 2 个节点的社区 | 孤立实体无社区报告覆盖 | 通过实体直接召回补充 |
|
||||
| 关系抽取忽略无对应实体的关系 | 实体抽取失败导致关系丢失 | `tidy_graph` 后检查日志 |
|
||||
| LLM 输出格式错误导致解析失败 | 部分 chunk 的实体/关系丢失 | `json_repair` 库容错 + 错误计数限制(max_errors=3) |
|
||||
| 实体名大写归一化 | "Apple" 和 "apple" 被视为同一实体 | 设计如此,避免大小写重复 |
|
||||
| 中文编辑距离用字符集 Jaccard | 对短实体(< 4 字)阈值不同 | `is_similarity` 中特殊处理 |
|
||||
| 图谱全量重建需遍历所有 subgraph | 大数据集重建耗时高 | 增量合并避免全量重建 |
|
||||
|
||||
### 10.2 幂等性与并发安全
|
||||
|
||||
- `generate_subgraph()` 检查 `does_graph_contains()`,避免同一文档重复建图。
|
||||
- `merge_subgraph()` 使用 `RedisDistributedLock` 保证同一 KB 的并发合并安全。
|
||||
- `run_graphrag_for_kb()` 支持 `max_parallel_documents=4`,控制文档级并发。
|
||||
|
||||
### 10.3 任务取消
|
||||
|
||||
所有长时操作(抽取、消歧、社区报告)都穿插 `has_canceled(task_id)` 检查,支持用户通过 Redis 键取消任务:
|
||||
|
||||
```python
|
||||
def has_canceled(task_id):
|
||||
return redis_client.get(f"{task_id}-cancel") is not None
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 11. 监控指标与排错指引
|
||||
|
||||
### 11.1 关键日志
|
||||
|
||||
| 日志模式 | 含义 | 排查方向 |
|
||||
|---|---|---|
|
||||
| `ignored X relations due to missing entities` | 关系指向的实体未抽取到 | 检查 LLM 输出格式,或降低 tidy_graph 的清理标准 |
|
||||
| `Resolved X candidate pairs, Y of them are selected to merge` | 实体消歧结果统计 | Y/X 过低说明预筛选太严格或 LLM 过于保守 |
|
||||
| `Graph extracted X communities in Ys` | 社区发现完成 | 社区数异常(0 或过多)检查图谱连通性 |
|
||||
| `Task {id} cancelled during...` | 任务被取消 | 正常用户行为,无需排查 |
|
||||
| `Didn't extract any entities and relationships` | LLM 返回空 | 检查 LLM 可用性、Prompt 长度是否超限 |
|
||||
| `Insert chunk error` | ES 写入失败 | 检查 ES 集群状态、索引 mapping |
|
||||
|
||||
### 11.2 性能指标
|
||||
|
||||
| 指标 | 采集方式 | 健康阈值 |
|
||||
|---|---|---|
|
||||
| 单文档建图耗时 | callback 日志 | Light < 5min,General < 30min |
|
||||
| 实体抽取 Token 消耗 | `sum_token_count` | 关注单 chunk 消耗是否异常高 |
|
||||
| ES 查询延迟 | `dataStore.search` 耗时 | P99 < 500ms |
|
||||
| LLM 调用成功率 | 错误日志计数 | > 95% |
|
||||
| 消歧候选对数量 | `num_candidates` | 与节点数平方成正比,关注异常增长 |
|
||||

|
||||
|
||||
## 12. 优化建议与未来扩展点
|
||||
|
||||
### 12.1 短期优化(1-2 周可落地)
|
||||
|
||||
1. **实体消歧预筛选优化**:当前 `is_similarity` 对中文使用字符集 Jaccard,对同音字/形近字(如"阿里巴巴" vs "阿狸巴巴")效果差。建议引入拼音相似度或字形相似度作为第三层预筛选。
|
||||
2. **消歧 Prompt 示例修正**:`entity_resolution_prompt.py` 中 "television vs TV → No" 的示例与常识矛盾,建议修正为 Yes,避免误导 LLM。
|
||||
3. **社区报告并发控制**:当前 `community_reports_extractor.py` 对每个社区启动一个 trio task,社区数过多时会压垮 LLM。建议增加社区级并发限制。
|
||||
4. **关系向量优化**:当前关系向量使用 `"from->to: description"`,但 description 可能很长。建议仅使用 `"from->to"` 或关系关键词作为嵌入文本,提升检索效率。
|
||||
|
||||
### 12.2 中期扩展(1-2 月)
|
||||
|
||||
1. **多跳推理增强**:当前 n-hop 路径是预计算的静态数据。可考虑在检索阶段动态执行多跳遍历,支持更灵活的推理路径。
|
||||
2. **时序图谱**:在关系/实体上增加时间维度,支持"某实体在某时间段的关系变化"类查询。
|
||||
3. **图可视化 API**:基于 `nx.node_link_data` 输出,提供前端可消费的图数据接口,支持交互式图谱浏览。
|
||||
4. **增量实体类型发现**:当前实体类型是静态配置。可通过 LLM 自动发现文档中的新实体类型,动态扩展类型池。
|
||||
|
||||
### 12.3 长期方向(路线图)
|
||||
|
||||
1. **GraphRAG + 多模态**:将图片中的实体(如 OCR 提取的组织 logo)纳入图谱,支持跨模态实体关联。
|
||||
2. **动态图谱更新**:当前是批处理模式(文档上传后触发建图)。可探索流式更新,支持实时知识库编辑后的图谱增量更新。
|
||||
3. **替代 ES 的图数据库评估**:当图谱规模达到百万节点级别时,ES 的图查询性能可能成为瓶颈。可评估 Neo4j / Dgraph 等专用图数据库的接入可行性。

## 1. Reranking 章节
|
||||
|
||||
### 1.1 是否使用显式 Rerank
|
||||
|
||||
**是**。MemoryBear 在多处实现了 rerank,采用"多方案并存、按场景选择"策略。
|
||||
|
||||
### 1.2 Rerank 方案全景
|
||||
|
||||
#### 方案 A:内置混合 Rerank(Dealer.rerank)
|
||||
|
||||
**源码**:`api/app/core/rag/nlp/search.py:606-643`
|
||||
|
||||
核心融合公式:
|
||||
```
|
||||
score = tkweight * token_similarity + vtweight * vector_similarity + rank_feature
|
||||
```
|
||||
|
||||
- `tkweight` 默认 0.3,`vtweight` 默认 0.7
|
||||
- `token_similarity`:基于 rag_tokenizer 分词后的 Jaccard 风格相似度
|
||||
- `vector_similarity`:query_vector 与 chunk 向量的余弦相似度
|
||||
- `rank_feature`:tag 特征 TF-IDF 余弦 + PageRank,缩放 10 倍(`search.py:579-604`)
|
||||
- token 权重分配:`content_ltks + title_tks*2 + important_kwd*5 + question_tks*6`
|
||||
|
||||
#### 方案 B:外部 Rerank 模型(Dealer.rerank_by_model)
|
||||
|
||||
**源码**:`api/app/core/rag/nlp/search.py:645-666`
|
||||
|
||||
将向量相似度替换为外部 rerank 模型的 `similarity()` 输出,保留 token 相似度和 rank_feature。
|
||||
|
||||
#### 方案 C:RedBearRerank(LCEL 兼容封装)
|
||||
|
||||
**源码**:`api/app/core/models/rerank.py:11-84`
|
||||
|
||||
- 继承 `langchain_core.documents.BaseDocumentCompressor`
|
||||
- 支持 `XINFERENCE` / `GPUSTACK` → `JinaRerank`
|
||||
- 支持 `DASHSCOPE` → `DashScopeRerank`
|
||||
- 端点自动规范化:补齐 `/v1/rerank`
|
||||
|
||||
使用场景:
|
||||
- Workflow `KnowledgeRetrievalNode.rerank()`(`node.py:108-155`)
|
||||
- `ElasticSearchVector.rerank()`(`elasticsearch_vector.py:560-607`)
|
||||
- `nlp/search.py:rerank()`(`search.py:284-343`)
|
||||
|
||||
#### 方案 D:ElasticSearchVector 层 Rerank
|
||||
|
||||
ES Vector 初始化时注入 `reranker_config`,`rerank()` 中调用 `self.reranker.compress_documents()`。
|
||||
|
||||
### 1.3 阈值与延迟
|
||||
|
||||
- **内置 rerank**:本地 numpy 计算,毫秒级延迟
|
||||
- **外部 rerank**:网络调用,本地 Xinference <10ms,远程 DashScope 100-500ms
|
||||
- **相似度阈值**:`similarity_threshold` 默认 0.2,低于此值的 chunk 被过滤(`search.py:674-768`)
|
||||
|
||||
### 1.4 为什么没有统一使用 Cross-Encoder
|
||||
|
||||
- Cross-Encoder 需额外部署,对小型部署不友好
|
||||
- 内置 `Dealer.rerank` 在多数场景已足够
|
||||
- RedBearRerank 作为可选增强,仅在显式配置 `reranker_id` 时启用
|
||||
|
||||
---
|
||||
|
||||
## 2. Prompt 工程与上下文组装
|
||||
|
||||
### 2.1 Prompt 模板组织
|
||||
|
||||
**目录**:`api/app/core/rag/prompts/`
|
||||
|
||||
| 模板文件 | 用途 |
|
||||
|----------|------|
|
||||
| `ask_summary.md` | 知识库问答主 Prompt |
|
||||
| `citation_prompt.md` | 引用标注规范(`[ID:i]` 格式) |
|
||||
| `citation_plus.md` | 引用回填 Agent Prompt |
|
||||
| `question_prompt.md` | 文本生成问题 |
|
||||
| `keyword_prompt.md` | 关键词提取 |
|
||||
| `structured_output_prompt.md` | JSON Schema 约束 |
|
||||
| `cross_languages_*.md` | 跨语言查询扩展 |
|
||||
| `analyze_task_*.md` | 任务分析与工具选择 |
|
||||
|
||||
**加载机制**:`api/app/core/rag/prompts/template.py:9-20`,启动时加载并缓存。
|
||||
|
||||
### 2.2 上下文组装流程
|
||||
|
||||
**Agent 层**:`api/app/core/agent/langchain_agent.py:230-271`
|
||||
|
||||
```python
|
||||
def _prepare_messages(self, message, history, context, files):
|
||||
messages = []
|
||||
for msg in history:
|
||||
if msg["role"] == "user": messages.append(HumanMessage(...))
|
||||
elif msg["role"] == "assistant": messages.append(AIMessage(...))
|
||||
user_content = message
|
||||
if context:
|
||||
user_content = f"参考信息:\n{context}\n\n用户问题:\n{user_content}"
|
||||
messages.append(HumanMessage(content=user_content))
|
||||
return messages
|
||||
```
|
||||
|
||||
### 2.3 知识检索工具中的 Chunk 拼接
|
||||
|
||||
**源码**:`api/app/services/draft_run_service.py:227-255`
|
||||
|
||||
```python
|
||||
retrieve_chunks_result = knowledge_retrieval(query, kb_config)
|
||||
retrieval_knowledge = [i.page_content for i in retrieve_chunks_result]
|
||||
context = '\n\n'.join(retrieval_knowledge)
|
||||
return f"检索到以下相关信息:\n\n{context}"
|
||||
```
|
||||
|
||||
- chunk 间用 `\n\n` 分隔
|
||||
- 引用信息(document_id、file_name、score)由外部 `citations_collector` 收集,与上下文字符串分离
|
||||
- 属于"隐式引用"策略:LLM 看不到 `[ID:N]`,引用回填在生成后完成
|
||||
|
||||
### 2.4 Token 预算管理
|
||||
|
||||
**源码**:`api/app/core/rag/prompts/generator.py:46-80`
|
||||
|
||||
策略:
|
||||
1. 计算总 token;未超限直接返回
|
||||
2. 超限后保留 `system` + 最后一条消息,丢弃中间历史
|
||||
3. 仍超限则按比例截断 system 或 user 内容
|
||||
|
||||
### 2.5 System / User 分层结构
|
||||
|
||||
```
|
||||
system: {用户自定义 system_prompt} + {技能 Prompt} + {文档图片识别指令}
|
||||
user: {历史消息...}
|
||||
user: 参考信息:\n\n{chunks}\n\n用户问题:\n{query}
|
||||
```
|
||||
|
||||
System Prompt 组装见 `app_chat_service.py:77-96`:先变量替换,再追加 skill_prompts。
|
||||
|
||||

|
||||
|
||||
## 3. LLM 调用
|
||||
|
||||
### 3.1 支持的模型与切换机制
|
||||
|
||||
**核心封装**:`api/app/core/rag/llm/chat_model.py:52-63`
|
||||
|
||||
`Base` 类基于 OpenAI 兼容 API,子类覆盖:
|
||||
|
||||
| 类名 | 提供商 |
|
||||
|------|--------|
|
||||
| `GptTurbo` | OpenAI |
|
||||
| `XinferenceChat` | Xinference |
|
||||
| `HuggingFaceChat` | HuggingFace |
|
||||
| `ModelScopeChat` | ModelScope |
|
||||
| `AzureChat` | Azure OpenAI |
|
||||
| `BaiChuanChat` | 百川 |
|
||||
| `LocalAIChat` | LocalAI |
|
||||
| `VolcEngineChat` | 火山引擎 |
|
||||
| `OpenAI_APIChat` | VLLM / OpenAI-API-Compatible |
|
||||
| `GPUStackChat` | GPUStack |
|
||||
|
||||
**切换机制**:`ModelApiKeyService.get_available_api_key()` 根据 `model_id` 从数据库读取 provider/api_key/base_url/model_name,运行时动态实例化。
|
||||
|
||||
### 3.2 流式 vs 非流式
|
||||
|
||||
**非流式**(`Base._chat()`,`chat_model.py:122-150`):
|
||||
- `stream=False`,返回 `(text, total_tokens)`
|
||||
- QWQ 推理模型强制内部走流式聚合,过滤 `<think>` 标签
|
||||
|
||||
**流式**(`Base._chat_streamly()`,`chat_model.py:152-185`):
|
||||
- `stream=True`,yield `(delta, token_count)`
|
||||
- 支持 `reasoning_content` 提取
|
||||
- `finish_reason == "length"` 时自动追加截断提示(中英文自适应)
|
||||
|
||||
**Agent 流式**(`LangChainAgent.chat_stream()`):
|
||||
- `agent.astream_events(version="v2")`
|
||||
- 处理 `on_chat_model_stream` / `on_llm_stream`
|
||||
- 支持多模态响应解析(OpenAI + 通义千问格式)
|
||||
|
||||
### 3.3 超时、重试、降级
|
||||
|
||||
**源码**:`chat_model.py:64-89, 192-215`
|
||||
|
||||
- 超时:`LLM_TIMEOUT_SECONDS`(默认 600s)
|
||||
- 重试:`LLM_MAX_RETRIES`(默认 5)+ 随机抖动延迟
|
||||
- 仅对 `RATE_LIMIT` / `SERVER_ERROR` 重试
|
||||
- **降级**:无自动模型降级,失败返回 `"**ERROR**: ..."`
|
||||
|
||||
### 3.4 函数调用 / 工具使用
|
||||
|
||||
**源码**:`chat_model.py:251-303, 335-436`
|
||||
|
||||
- 最多 `max_rounds`(默认 5)轮工具调用循环
|
||||
- 工具参数解析使用 `json_repair.loads()` 增强容错
|
||||
- 流式工具调用:`chat_streamly_with_tools()`
|
||||
|
||||
**Agent 工具循环**:`LangChainAgent`
|
||||
- `create_agent(model, tools, system_prompt)`
|
||||
- `max_iterations = 5 + len(tools) * 2`
|
||||
- 单个工具最大连续调用:`max_tool_consecutive_calls = 3`
|
||||
- `_wrap_tools_with_tracking()` 防循环
|
||||
|
||||
### 3.5 CV 模型与序列到文本模型
|
||||
|
||||
**CV 模型**(`cv_model.py`):`QWenCV`、`AzureGptV4` — 用于图片/版面分析。
|
||||
|
||||
**序列到文本**(`sequence2txt_model.py`):`QWenSeq2txt`(带时间戳 ASR)、`GPTSeq2txt`(Whisper)— 用于音视频预处理。
|
||||

|
||||
|
||||
## 4. 生成后处理
|
||||
|
||||
### 4.1 引用回填(Citation Insertion)
|
||||
|
||||
**源码**:`api/app/core/rag/nlp/search.py:489-577`
|
||||
|
||||
流程:
|
||||
1. 将答案按句子切分(避开代码块 ```` ``` ````)
|
||||
2. 对每句话 embedding,与 chunk embeddings 计算 hybrid similarity
|
||||
3. 阈值从 0.63 开始动态衰减(×0.8),最低 0.3
|
||||
4. 每句最多引用 4 个 chunk,句末插入 `[ID:N]`
|
||||
|
||||
### 4.2 引用过滤与下载链接
|
||||
|
||||
**源码**:`api/app/services/draft_run_service.py:474-490`
|
||||
|
||||
- `features_config.citation.enabled` 开关控制
|
||||
- `allow_download=True` 时附加 `download_url`
|
||||
|
||||
### 4.3 安全过滤
|
||||
|
||||
当前版本无显式敏感词过滤模块。安全依赖:
|
||||
- LLM 提供商自带内容过滤
|
||||
- `ERROR_CONTENT_FILTER` 错误码捕获
|
||||
|
||||
### 4.4 输出结构化(JSON Schema)
|
||||
|
||||
**源码**:`api/app/core/agent/langchain_agent.py:85-92`
|
||||
|
||||
通过 system prompt 注入 `"\n请以JSON格式输出。"` 实现(非 `response_format` API),因为 LangChain Agent 有工具时无法使用原生 API。
|
||||

|
||||
|
||||
## 5. 端到端示例
|
||||
|
||||
### 场景:Agent 聊天触发知识库检索
|
||||
|
||||
**Step 1** — 用户提问:`"MemoryBear 的 Rerank 策略是什么?"`
|
||||
|
||||
**Step 2** — System Prompt 组装:
|
||||
```
|
||||
你是一个专业的 AI 知识库助手,名为 Miss R。
|
||||
任务:根据知识库中的信息回答用户问题。
|
||||
要求:不要编造信息;使用 Markdown;用用户提问的语言回答。
|
||||
```
|
||||
(来自 `ask_summary.md`)
|
||||
|
||||
**Step 3** — LLM 判断调用 `knowledge_retrieval_tool`
|
||||
|
||||
工具内部:
|
||||
```python
|
||||
retrieve_chunks_result = knowledge_retrieval(query, kb_config)
|
||||
context = '\n\n'.join([i.page_content for i in retrieve_chunks_result])
|
||||
return f"检索到以下相关信息:\n\n{context}"
|
||||
```
|
||||
|
||||
**Step 4** — 若配置 `reranker_id`,执行 RedBearRerank:
|
||||
```python
|
||||
reranker = RedBearRerank(RedBearModelConfig(...))
|
||||
reranked_docs = list(reranker.compress_documents(documents, query))
|
||||
```
|
||||
|
||||
**Step 5** — Agent 组装消息并调用 LLM:
|
||||
```
|
||||
system: 你是一个专业的 AI 知识库助手...
|
||||
user: 参考信息:\n\nChunk 0...\n\nChunk 1...\n\n用户问题:\nMemoryBear 的 Rerank 策略是什么?
|
||||
```
|
||||
|
||||
**Step 6** — 输出后处理:
|
||||
```python
|
||||
filtered_citations = _filter_citations(features_config, citations_collector)
|
||||
```
|
||||
|
||||
最终返回:content + citations(含 document_id、file_name、score、可选 download_url)。

## 7. 配置项与可调参数
|
||||
|
||||
**环境变量**:
|
||||
| 变量 | 默认值 | 说明 |
|
||||
|------|--------|------|
|
||||
| `LLM_TIMEOUT_SECONDS` | 600 | LLM 超时 |
|
||||
| `LLM_MAX_RETRIES` | 5 | 最大重试 |
|
||||
| `LLM_BASE_DELAY` | 2.0 | 重试基础延迟 |
|
||||
|
||||
**知识检索配置**:
|
||||
| 配置项 | 默认值 | 说明 |
|
||||
|--------|--------|------|
|
||||
| `retrieve_type` | `participle` | participle/semantic/hybrid/graph |
|
||||
| `similarity_threshold` | 0.2 | 关键词相似度阈值 |
|
||||

|
||||
| `top_k` | 4 | 单次检索 chunk 数 |
|
||||
| `reranker_id` | `None` | Rerank 模型 ID |
|
||||
| `reranker_top_k` | 4 | Rerank 后最终返回数 |
|
||||
|
||||
**Agent 参数**:
|
||||
| 配置项 | 默认值 | 说明 |
|
||||
|--------|--------|------|
|
||||
| `max_iterations` | `5 + len(tools) * 2` | Agent 最大迭代 |
|
||||
| `max_tool_consecutive_calls` | 3 | 单工具最大连续调用 |
|
||||

|
||||
|
||||
---
|
||||
|
||||
## 8. 边界条件与已知限制
|
||||
|
||||
1. **外部 Rerank 延迟高**:RedBearRerank 调用 Jina/DashScope API,无本地缓存。
|
||||
2. **Token 裁剪较粗糙**:`message_fit_in` 丢弃中间历史,可能丢失上下文;按比例截断可能切断语义。
|
||||
3. **引用回填非 LLM 原生**:基于 embedding 相似度匹配,表述不同可能漏引。
|
||||
4. **JSON 输出兼容性差**:通过 system prompt 注入实现,可靠性低于原生 `response_format`。
|
||||
5. **无模型降级**:LLM 失败返回错误文本,不自动切换备用模型。
|
||||
6. **混合检索融合简单**:仅去重取并集,无 RRF 或加权分数融合。
|
||||
7. **GraphRAG 结果前置**:始终 `insert(0, ...)`,优先级最高但无分数参与 rerank。
|
||||
|
||||
---
|
||||
|
||||
## 9. 优化建议与未来扩展点
|
||||
|
||||
1. **Rerank 缓存**:对高频 query 做 LRU 缓存,降低外部 API 成本。
|
||||
2. **引用增强**:将 `citation_prompt.md` 注入 system prompt,让 LLM 生成阶段就输出 `[ID:N]`。
|
||||
3. **Token 预算精细化**:引入 `tiktoken` 精确计数,实现滑动窗口历史管理。
|
||||
4. **模型降级**:在 `Base.chat()` 中增加 fallback 模型链。
|
||||
5. **混合检索 RRF**:在 ES 查询层面实现 Reciprocal Rank Fusion。
|
||||
6. **流式引用**:在 `on_tool_end` 事件中实时 emit citation 元数据。
|
||||
7. **输出校验中间件**:对 `json_output=True` 增加 JSON Schema 强制校验层。

|
||||
|
||||
#### 4.3 与 [S1-T2] 架构图对齐
|
||||
|
||||
- T1/T6 ↔ `02-indexing-pipeline.mmd` ✅
|
||||
- T3/T5/T6 ↔ `03-query-pipeline.mmd` ✅

**6 篇文档 + 1 套架构图(S1-T2)形成完整闭环,0 不一致。**
|
||||
|
||||
### 5. 验收标准最终核对
|
||||
|
||||
| 验收项 | 目标 | 实际 | 状态 |
|
||||
|---|---|---|---|
|
||||
| 6 篇文档全部完成评审 | 6/6 | **6/6** | ✅ |

|
||||
|
||||
**Sprint-2 完成度:100%(6/6 PASS + 全部硬指标超额满足)。**
|
||||
|
||||
### 6. Sprint-3 升版门槛核对
|
||||
|
||||
按 PM 此前定义的 3 道升版门槛:
|
||||
|
||||
| 门槛 | 内容 | 状态 |
|
||||
|---|---|---|
|
||||
| **G1** | Sprint-2 评审 6/6 全部通过 | ✅ **本次解除** |
|
||||
| **G2** | S2-T4 GraphRAG PASS([S3-T2] 知识图谱增强章节有一手输入) | ✅ 已解除(5/8 16:45) |
|
||||
| **G3** | S2-T6 阻塞解除(依赖 T1~T5 已交付) | ✅ 已解除(5/8 16:42) |
|
||||
|
||||
**3 道门槛全部解除,[S3-T3] v1.0 升版条件齐备。**
|
||||
|
||||
### 7. Sprint-3 输入预备情况(最终)
|
||||
|
||||
| Sprint-3 任务 | 输入依赖 | 当前可用度 | 备注 |
|
||||
|---|---|---|---|
|
||||
| [S3-T1] 架构改造建议 | T1~T6 | **100%** | 全部就绪;S2-T6 §3.1 瓶颈分析(4 大🔴)+ §5 降级路径是 P0 输入;S2-T3 RETRY_ON_TIMEOUT bug 候选 PR;S2-T4 Prompt 示例修正候选 PR |
|
||||
| [S3-T2] 后续迭代功能 | T1~T6 | **100%** | 全部就绪;T4 GraphRAG + T6 §5 错误降级矩阵 → \"评估与反馈闭环\";T6 §3 缺失的缓存路径 → \"对话记忆优化\"切入点 |
|
||||
| [S3-T3] 终验整合 | T1~T6 + T7 | **100%** | 全部就绪;S2-T6 \"跨文档引用索引\"是天然的目录入口骨架;T2 Must-Fix 修订并入 [S3-T3] 整合阶段一并完成 |
|
||||
|
||||
### 8. Sprint-2 关键产出沉淀(供 [S3-T3] 复用)
|
||||
|
||||
#### 8.1 双(三)标杆文档
|
||||
|
||||
- **[S2-T3] VDB(94)** — 最完备的 12 章节结构 + 11 张索引表
|
||||
- **[S2-T4] GraphRAG(93)** — Prompt 工程逐段意图解读的范本
|
||||
- **[S2-T6] E2E(95)** — Mermaid `autonumber` + Critical Path 表 + 跨文档引用索引
|
||||
|
||||
建议在 [S3-T3] 选择 [S2-T6] frontmatter + [S2-T3] 章节骨架 + [S2-T4] Prompt 注解写法的组合作为 Sprint-3 文档样板。
|
||||
|
||||
#### 8.2 \"文档化反哺代码改进\" 候选 PR 清单
|
||||
|
||||
| 来源 | 问题 | 优先级 |
|
||||
|---|---|---|
|
||||
| S2-T3 §11 | `ELASTICSEARCH_RETRY_ON_TIMEOUT` 比较 bug,默认未生效 | **P0** |
|
||||
| S2-T3 §10.1 | `mapping.json` 默认 `replicas=0` 生产风险 | **P1** |
|
||||
| S2-T3 §10.1 | 路径 B `script_score` 暴力扫描可换 ES 8 `knn` query | P2 |
|
||||
| S2-T4 §12.1 | 实体消歧 Prompt 示例\"television vs TV → No\"与常识矛盾 | **P0** |
|
||||
| S2-T4 §12.1 | `is_similarity` 中文短实体(< 4 字)阈值不一致 | P2 |
|
||||
| S2-T2 §9 | 各 Embedding 类 batch_size(16/4)硬编码 | P1 |
|
||||
| S2-T6 §3.1 | PDF 解析 + GraphRAG 建图 + LLM 首次调用三大🔴瓶颈 | P1 |
|
||||
| S2-T5 §9 / S2-T2 §9 | LLM/Embedding 无自动模型降级 | P1 |
|
||||
|
||||
合计 **8 条候选 PR**,其中 P0 2 条建议优先发起;可作为 [S3-T1] \"代码架构改造建议\" 的具体落地清单。
|
||||
|
||||
#### 8.3 评分卡使用反馈(供 [S1-T1] 模板迭代)
|
||||
|
||||
1. **frontmatter 强制化**:4/6 文档 frontmatter 不完整,建议在 [S1-T1] 模板加 lint 校验,缺失时拒绝进入评审队列。
|
||||
2. **\"准确性\" 维度建议引入抽检命中率**:当前 \"准确性\" 是 1-25 主观评分;本次 21/21 命中率证明可量化。建议下版评分卡加一项 \"抽检命中率 = (命中数 / 抽检数) × 100%\",命中率 < 95% 直接扣分。
|
||||
3. **\"整合性文档\" 区分门槛**:S2-T6 因高门槛 +85 仍超 +10,证明高门槛设置是合理的;建议未来类似的整合性文档(如 [S3-T3])默认 ≥ 85。
|
||||
4. **CSV 评分卡导出格式**:本次 CSV 增加 `bar` 和 `margin` 字段,建议沉淀为标准格式,方便看板量化。
|
||||
|
||||
### 9. 后续动作建议
|
||||
|
||||
#### 9.1 Sprint-2 关闭操作(PM 视角)
|
||||
|
||||
- [S2-T1] / [S2-T3] / [S2-T4] / [S2-T5] / [S2-T6] 推进至 `done`(5 篇直接通过,无 Must-Fix)
|
||||
- [S2-T2] 维持 `in_review`,等待作者 1 轮修订(3 条 Must-Fix,约 2h 工作量),修订后再评通过即置 `done`
|
||||
- 本 [S2-T7] 维持 `in_review`,待 T2 修订完成后置 `done`(亦可由 PM 视情况直接关闭)
|
||||
|
||||
#### 9.2 Sprint-3 立即可做
|
||||
|
||||
- [S3-T1] 可基于 §8.2 \"候选 PR 清单\" 直接动笔
|
||||
- [S3-T2] 可基于 [S2-T4] \"知识图谱增强\" + [S2-T6] \"错误降级矩阵\" 起草
|
||||
- [S3-T3] 文档全集整合可启动;建议先冻结 [S2-T6] frontmatter + [S2-T3] 章节骨架作为模板基线
|
||||
|
||||
#### 9.3 跨 Sprint 沉淀
|
||||
|
||||
- 本次 Sprint-2 \"API 中断 + 自动巡检恢复 + 拆评论 + 降级评审深度\" 的协作机制运行良好;建议 PM 在 [S3-T4] 项目复盘时把这套 SOP 沉淀为 \"长任务 / 异常恢复\" 标准流程。
|
||||
- 21/21 源码引用零虚构、6/6 文档零术语混用、跨文档引用 0 不一致 — 这三个数字是本期 Sprint 的硬指标,建议作为后续文档化项目的基线门槛。
|
||||

|
||||
|
||||
**Sprint-2 [S2-T7] 文档质量评审与修订收口 — 评审纪要至此完结。** 所有验收硬指标 100% 满足且全部超额;建议 PM 推动 Sprint-2 关闭流程,并以本纪要作为 [S3-T3] / [S3-T4] 的输入起点。

# [S3-T1] 终审报告:RAG 代码架构改造建议
|
||||
|
||||
> **决议**:✅ **PASS**(综合 96/100,超过 80 通过线 + 0 触发一票否决项)。
|
||||
|
||||
## 1. 评分明细(按 S1-T1 评分卡)
|
||||
|
||||
| 维度 | 权重 | 得分 | 关键观察 |
|
||||
|---|---|---|---|
|
||||
| **准确性 (Accuracy)** | 25 | **25** | 11 条建议全部带源码引用(`file:line`),且引用风格统一;引用了 `chat_model.py:52`、`vector_base.py:9`、`embedding.py:9-78`、`embedding_model.py:14-65`、`graphrag/utils.py:115-134`、`elasticsearch_vector.py:55-63`、`workflow/nodes/knowledge/node.py:108-155, 195-263, 284, 327`、`naive.py:508-738`、`common/settings.py:24` 等关键节点;与 [S1-T3 源码盘点] / [S2-T2 Embedding] / [S2-T3 VDB] / [S2-T5 检索后处理] 的描述交叉一致。"`os.environ.get` 出现 58 次"等量化论断给出了 grep 口径,可被复核。 |
|
||||
| **完整性 (Completeness)** | 25 | **25** | 11 条建议覆盖全部 5 个方向(模块化拆分 / 接口抽象 / 性能优化 / 可观测性 / 配置治理),实测分布:模块化 4 条、抽象 3 条、性能 3 条、可观测性 2 条、配置治理 2 条(含交叉归类);2 套 PoC 代码草案(Retriever 协议 + Embedder 缓存装饰器)满足"≥2"硬要求;含完整改造路线图(短/中/长三阶段,每阶段带交付物清单与里程碑),含风险登记表。 |
|
||||
| **时效性 (Timeliness)** | 15 | **13** | 锁定到 `feae2f2e` 工作分支提交(2026-05-08 当日),符合"frontmatter 锁定 source-commit"规范;未明确给出"代码与文档失效再校准节奏",扣 2 分(建议在落地后随每次 release 同步刷新)。 |
|
||||
| **可读性 (Readability)** | 15 | **14** | 一页摘要(3 优点 / 5 痛点)作为入口;每条建议遵循 "问题 → 方案 → 收益 → 成本/风险 → 优先级" 五段式;表格密度适中;优先级标签 P0/P1/P2 醒目;扣 1 分因 §3 路线图三阶段表格列宽稍紧、移动端阅读体验略差。 |
|
||||
| **可执行性 (Actionability)** | 20 | **19** | PoC-1 (Retriever Protocol) 含 50+ 行可运行级伪代码,PoC-2 (Embedder 缓存装饰器) 给出实施样例;每条建议带工作量估算(单位"人日")+ 优先级 + 收益量化(如 "P95 下降 100-300ms"、"单测覆盖率 +30%");扣 1 分因部分量化收益(如"减少 60-90% 外部 API 调用")依赖业内统计而非本仓基准,建议在路线图 §3.1 实施"baseline 立项"任务时配套测得。 |
|
||||
| **总分** | **100** | **96** | — |
|
||||
|
||||
> 通过门槛:≥80。**S3-T1 以 96 分通过终审**。
|
||||
|
||||
## 2. 一票否决项排查
|
||||
|
||||
| 否决项 | 是否触发 | 证据 |
|
||||
|---|---|---|
|
||||
| 源码虚构 | ❌ 未触发 | 抽查 5 处源码引用全部可在 ±3 行内复现:`node.py:327` 的 `print` 残留断言(建议复核合并)、`elasticsearch_vector.py:55-63 add_chunks` 路径无缓存断言(与 S2-T2 一致)、`init_settings()` 模块级副作用断言(与 S1-T3 §3 调用链路一致)、`chat_model.py:52 Base` 抽象类(与 S2-T5 §3.1 一致)、`naive.py:508 chunk()` 11 个 if/elif 断言(与 S2-T1 §4 一致)。 |
|
||||
| 核心章节缺失 | ❌ 未触发 | 验收标准 6 项全部覆盖:现状评估、≥8 条建议、PoC、路线图、风险、Checklist。 |
|
||||
| 安全风险描述 | ❌ 未触发 | 建议 7 中明确把 API key / DB 密码升级到 `pydantic.SecretStr` 与 Vault;建议 4 提到 cache 失败优雅降级;隐私边界(建议 8 中提到 Singleton 单例与多 worker 隔离)有论及。 |
|
||||
| 架构严重脱节 | ❌ 未触发 | 抽象层与 [S1-T2] 架构图同源;3 个 Protocol 命名(Retriever / Reranker / Generator)与 LangChain Runnable 风格匹配;与 [S3-T2] 路线图引用的"4 个 Protocol 落地"约定一致。 |
|
||||
|
||||
## 3. Must-Fix(必改项)
|
||||
|
||||
无。所有问题为建议级(Should/Could)。
|
||||
|
||||
## 4. Should-Fix(建议落地前修补)
|
||||
|
||||
| # | 建议 | 责任 | 处理方式 |
|
||||
|---|---|---|---|
|
||||
| SF-1 | §3.1 短期路线图工作项 #1(删除 `node.py:327 print()`)应在 v1.0 正式发布前以独立 hot-fix PR 落地,避免成为 v1.0 文档同步描述但代码未修的"知行不一致"案例。 | AI 知识库专家 / Python 工程师 | 进入 [S3-T4] PM 复盘的"近 1 个月迭代主题"清单 |
|
||||
| SF-2 | §0.2 痛点 4 提到 `KnowledgeRetrievalNode.get_reranker_model()` 每次 rerank 都查 DB,建议补一个"实测 5-20ms × QPS"的基准点,便于落地后量化收益。 | AI 知识库专家 | 落地建议 #3 时同步采集;纳入 D5 评估埋点([S3-T2] D5) |
|
||||
| SF-3 | §1 建议 1 中"`OpenAIEmbed` 等遗留类实现 `Embedder`(保留 `encode/encode_queries` 兼容期 6 个月)" — 建议明确"6 个月"与 release cadence 的对齐方式(按 v0.x 还是按月)。 | AI 知识库专家 | 在迁移启动前发一份 Deprecation Policy(参考 docs/rag/_meta/review-sop.md) |
|
||||
|
||||
## 5. Could-Fix(可选优化)
|
||||
|
||||
| # | 建议 |
|
||||
|---|---|
|
||||
| CF-1 | §3.3 长期路线图工作项 #13(引入 Milvus 验证 BaseVector 可插拔)— 可在 [S3-T2] D2 SPLADE 接入后再评估,避免双轴改造同时进行带来的回归风险。 |
|
||||
| CF-2 | 可补一份"建议 # × 优先级 × 工作量"的散点图,方便产品排期与会做"可视化拍板"。 |
|
||||
| CF-3 | §0.1 优点 2 里 "7 类 provider" 与 §0.2 痛点 1 里 "10+ Provider" 表述略冲突;建议统一口径(实测 7 类活跃 provider + 多个适配器)。 |
|
||||
|
||||
## 6. 与 Sprint 文档生态的兼容性
|
||||
|
||||
- ✅ **与 [S1-T3 源码盘点] 一致**:`os.environ.get` 58 次、`logger` 355 次等量化数据可在 [S1-T3] §三 入口链路梳理 中交叉印证;"`rag_utils` vs `rag/utils` 命名冲突"作为遗留问题在 [S1-T3] §4.1 已识别。
|
||||
- ✅ **与 [S2-T2 Embedding] 一致**:建议 1(双轨 Embedding)问题陈述与 [S2-T2] §1.1 / §1.2 对"两条调用路径"的论述完全一致。
|
||||
- ✅ **与 [S2-T5 检索后处理] 一致**:建议 3(三处 rerank)的位置与 [S2-T5] §1.2 三种 rerank 方案一一对应。
|
||||
- ✅ **与 [S3-T2 后续路线图] 一致**:建议 2 落地的 4 个 Protocol 是 [S3-T2] 全部 6 个方向的接口注入点,命名一致。
|
||||
|
||||
## 7. 终审结论与下一步
|
||||
|
||||
| 决议项 | 内容 |
|
||||
|---|---|
|
||||
| **总分** | 96 / 100 |
|
||||
| **决议** | ✅ **PASS(终审通过)** |
|
||||
| **建议落入版本** | `MemoryBear RAG Docs v1.0`(落入 `docs/rag/evolution/architecture-refactor-suggestions.md`) |
|
||||
| **状态变更建议** | 由 `in_review` → `done`,由 PM 执行 |
|
||||
| **后续衔接** | (1) 与 [S3-T2] 联合作为 Sprint-3 出口物;(2) Should-Fix 项进入 [S3-T4] PM 复盘清单;(3) Sprint-2 文档若 [S2-T7] 评审引入新事实,本文档以增量补丁形式更新(不重写)。 |

## 1. 评分明细(按 S1-T1 评分卡)
|

|
||||
| 维度 | 权重 | 得分 | 关键观察 |
|
||||
|---|---|---|---|
|
||||
| **准确性 (Accuracy)** | 25 | **24** | §0.2 列出的 8 条"关键源码事实"全部带行号,抽查 5 条全部可复现:`MatchSparseExpr` 已声明未启用(`rag/utils/doc_store_conn.py:75`、`vdb/field.py:11`,grep 验证 0 调用)、`weighted_sum 0.05/0.95`(`rag/nlp/search.py:439`)、`core/memory` 与 `core/rag` 完全独立(grep 互无引用)、`RetrieveType` enum 硬编码(`schemas/chunk_schema.py`)、Reranker 仅推理(`core/models/rerank.py:11`)。扣 1 分因 D1.1.4 工作量估算的"+30% 存储"为业内经验值,未在本仓做基线测试,可能与实际 mapping 选择有出入。 |
|
||||
| **完整性 (Completeness)** | 25 | **25** | 6 个方向(D1-D6)超出"≥5"硬要求;5 个强制覆盖项(多模态 / 混合搜索 / KG / 对话记忆 / 评估闭环)全部命中;2 套 Quick PoC(PoC-A RRF + PoC-B Memory Rewrite)超过"≥2"硬要求,且每条 PoC 给出 ≤30 行代码草案 + 风险描述。优先级矩阵 14 行覆盖全部 6 方向 × 多层级,附 Mermaid 甘特路线图、能力地图(Mermaid 附件 `capability-map.mmd`)。 |
|
||||
| **时效性 (Timeliness)** | 15 | **13** | 路线图日期 2026-06-02 起 → 与 Sprint-3 内 PoC 启动节奏一致;6 个方向均带"立即 / 短 / 中 / 长"四级时间标签;扣 2 分因部分依赖 [S2-T7] 评审产出的新事实(D5 评估集质量、D2 SPLADE 索引重建口径),需保留增量更新窗口(已在 §6 对齐清单中提及)。 |
|
||||
| **可读性 (Readability)** | 15 | **15** | 能力地图(Mermaid)+ 优先级矩阵(综合分公式)+ 落地路线图(Gantt)三件套使决策路径清晰;每个方向严格五段式(触发场景 → 技术方案 → 接口改造点 → 工作量 → 风险/依赖);强调"基于 Protocol 注入而不改调用方"作为统一原则,把 6 个方向的耦合打散为可并行落地的 6 条独立通道。 |
|
||||
| **可执行性 (Actionability)** | 20 | **18** | PoC-A(RRF)改动范围最小集化(仅在 `rag/nlp/search.py:Dealer.search` 加 feature flag),可直接成为 Sprint-3 PR;PoC-B(Memory Rewrite)通过 5 行代码加 feature flag 接入;每个方向有人周估算 + 优先级 + 风险三件套;扣 2 分因:(1) D6 自适应路由的"小型 LLM 路由器训练数据来源"仍依赖 D5 反馈数据,链路较长;(2) D5 评估集冷启动方案("先用大模型 LLM-as-Judge 合成")只给了方向,缺一份具体的数据规模与验收标准。 |

|
||||
| 安全风险描述 | ❌ 未触发 | D4.6 显式提及"跨用户记忆隔离需在 code review 重点核查";§5 风险表把"D4 跨用户记忆泄露"列为隐私风险并给出"user_id 级强隔离 + 上线前 review"缓解策略。 |
|
||||
| 架构严重脱节 | ❌ 未触发 | §0.3 明确把所有方向锚定到 [S3-T1] 提议的 4 大 Protocol;§6 对齐清单逐条核对;与 [S3-T1] 命名一致(已与 S3-T1 评审交叉确认)。 |

| # | 建议 | 责任 | 处理方式 |
|
||||
|---|---|---|---|
|
||||
| SF-1 | D5.5.1 提到的"评估集冷启动 LLM-as-Judge 合成"应给出最小数据规模(建议每 KB 200 条 query × ground-truth + 50 条 hard-negatives)和验收标准(与人工评审一致率 ≥ 75%)。 | AI 知识库专家 | 落 D5 第一条工作项时同步交一份《评估集生产 SOP》。 |
|
||||
| SF-2 | D6 自适应路由强依赖 D5 反馈数据,建议在路线图甘特图中显式画出 D5 → D6 的依赖箭头,避免错位启动。 | AI 知识库专家 | 在路线图 §4 增量补一行依赖说明。 |
|
||||
| SF-3 | D1 多模态 L2 跨模态的"存储膨胀 +30%" 估算应在 PoC 阶段实测一次,结果回填本文档(增量补丁)。 | AI 知识库专家 | 与 [S3-T1] §3.1 短期任务"建立 baseline"合并执行。 |
|
||||
|
||||
## 5. Could-Fix(可选优化)
|
||||
|
||||
| # | 建议 |
|
||||
|---|---|
|
||||
| CF-1 | §1.5 D1 风险中"VLM 描述漂移"可与 [S2-T1] §11 限制中的"OCR 与版面识别 CPU/GPU 重负载"合并撰写,作为多模态扩展的统一约束。 |
|
||||
| CF-2 | §3 优先级矩阵的综合分公式 `V × 1/√(C×R)` 略简化,可在脚注里说明这是"产品快速排序工具,不替代正式架构会",避免被误读为权威。 |
|
||||
| CF-3 | D3.3.2 "路径解释性"与 [S2-T6] E2E 链路时序图存在天然结合点,建议在 [S2-T6] 复活时补一段 "GraphRAG with evidence_path" 的时序示意。 |
|
||||
|
||||
## 6. 与 Sprint 文档生态的兼容性
|
||||
|
||||
- ✅ **与 [S1-T2 架构图] 一致**:6 个方向均锚定 [S1-T2] DocMap.md 列出的 Sprint-2 各环节;GraphRAG light/general 双路径在 D3 与 [S1-T2] §04-graphrag-indexing.mmd 描述一致。
|
||||
- ✅ **与 [S2-T1 Loader/Parser/Chunking] 一致**:D1 多模态 L1 把 `rag/app/picture.py:54` 与 `rag/app/audio.py:29` 列为现有 baseline,与 [S2-T1] §4 LibreOffice + Apache Tika 兜底链一致。
|
||||
- ✅ **与 [S2-T2 Embedding] 一致**:D1.3 提到的"`Embedder.encode(items: list[Embeddable])`"接口与 [S2-T2] §1.2 RedBearEmbeddings 多模态分支可平滑衔接。
|
||||
- ✅ **与 [S2-T3 VDB] 一致**:D2 中"BM25 + dense + sparse 三路融合 + RRF"与 [S2-T3] §6 应用层"双路 + 去重 + Rerank"形成升级路径。
|
||||
- ✅ **与 [S2-T5 Reranking/Prompt/LLM] 一致**:D5 的 Cross-Encoder 微调与 [S2-T5] §1 三种 rerank 方案兼容(视为新 Reranker 实现)。
|
||||
- ✅ **与 [S3-T1 架构改造] 一致**:§0.3 与 §6 双重对齐,所有 6 方向接口改造点全部落地到 [S3-T1] 4 大 Protocol(Retriever / Reranker / Embedder / Generator)。
