## 📋 能力概述
|
||
|
||
RAG引擎负责：
|
||
- 向量化存储（Embedding）
|
||
- 语义检索（Semantic Search）
|
||
- 检索增强生成（RAG）
|
||
- Rerank重排序
|
||

|
||
|
||
## 📊 依赖模块
|
||
|
||
**3个模块依赖（43%复用率）：**
|
||
1. **AIA** - AI智能问答（@知识库问答）
|
||
2. **ASL** - AI智能文献（文献内容检索）
|
||
3. **PKB** - 个人知识库（RAG问答）
|
||
|

|
||
|
||
## 💡 核心功能
|
||
|
||
### 1. 向量化存储
|
||
- 基于Dify平台
|
||
- Qdrant向量数据库（Dify内置）
|
||
|
||
### 2. 语义检索
|
||
- Top-K检索
|
||
- 相关度评分
|
||
- 多知识库联合检索
|
||
|
||
### 3. RAG问答
|
||
- 检索 + 生成
|
||
- 智能引用系统（100%准确溯源）

## 🏗️ 技术架构
|
||
|
||
**基于Dify平台：**
|
||
```typescript
|
||
// DifyClient封装
|
||
interface RAGEngine {
|
||
// 创建知识库
|
||
createDataset(name: string): Promise<string>;
|
||
|
||
// 上传文档
|
||
uploadDocument(datasetId: string, file: File): Promise<string>;
|
||
|
||
// 语义检索
|
||
search(datasetId: string, query: string, topK?: number): Promise<SearchResult[]>;
|
||
|
||
// RAG问答
|
||
chatWithRAG(datasetId: string, query: string): Promise<string>;
|
||
}
|
||
```

## 📈 优化成果
|
||
|
||
**检索参数优化：**
|
||
| 指标 | 优化前 | 优化后 | 提升 |
|
||
|------|--------|--------|------|
|
||
| 检索数量 | 3 chunks | 15 chunks | 5倍 |
|
||
| Chunk大小 | 500 tokens | 1500 tokens | 3倍 |
|
||
| 总覆盖 | 1,500 tokens | 22,500 tokens | 15倍 |
|
||
| 覆盖率 | ~5% | ~40-50% | 8-10倍 |
