# 增强版实体-关系提取规范
> 基于70+维结构化提取的实体关系扩展方案
> 创建时间: 2026-03-18
---
## 当前70+维中的实体关系定义
### 现有 entities 字段
```json
"entities": [
{"name": "基因/蛋白名称", "type": "gene/domain/database", "species": "物种", "description": "描述"}
]
```
**问题**:
- `type` 只有简单的3种类型
- 缺少表型、代谢物、处理/胁迫等实体类型
- 没有标准化的实体分类体系
### 现有 relations 字段
```json
"relations": [
{"source": "源实体", "target": "目标实体", "type": "关系类型", "description": "描述"}
]
```
**问题**:
- `type` 没有预定义的关系类型列表
- 缺少调控关系、表达关系等生物学关系

## 与现有70+维的整合建议
### 方案1: 扩展现有字段
保持现有 `entities` 和 `relations` 字段，但增强其内容规范：
```json
{
"entities": [
{
"id": "唯一标识",
"name": "实体名称",
"type": "gene|protein|organism|phenotype|treatment|metabolite|process|...",
"species": "物种",
"attributes": {},
"description": "描述"
}
],
"relations": [
{
"id": "关系唯一标识",
"source": "源实体ID",
"target": "目标实体ID",
"type": "activates|inhibits|regulates|expressed_in|involved_in|...",
"description": "关系描述",
"confidence": "high|medium|low",
"evidence": "证据来源"
}
]
}
```
### 方案2: 新增独立知识图谱字段
在70+维之外新增 `knowledge_graph` 字段：
```json
{
"knowledge_graph": {
"nodes": [...], // 实体
"edges": [...], // 关系
"pathways": [...], // 通路
"networks": [...] // 网络
}
}
```
### 方案3: 分层提取
- **第一层**: 现有70+维（结构化信息）
- **第二层**: 实体关系（知识图谱）
- **第三层**: 通路网络（系统生物学）
---
## 实施建议
### 1. 提示词修改
在 `extraction_prompt.md` 中扩展 `entities` 和 `relations` 的定义：
```markdown
"entities": [
{
"id": "唯一标识符（如FtSPL1）",
"name": "实体名称",
"type": "实体类型：gene|protein|organism|phenotype|treatment|metabolite|process|gene_family|protein_domain|...",
"species": "所属物种",
"attributes": {},
"description": "描述"
}
],
"relations": [
{
"id": "关系唯一标识",
"source": "源实体ID",
"target": "目标实体ID",
"type": "关系类型：activates|inhibits|regulates|expressed_in|upregulated_in|downregulated_in|involved_in|controls|homologous_to|orthologous_to|paralogous_to|member_of|contains|part_of|interacts_with|binds_to|...",
"description": "关系描述",
"confidence": "high|medium|low",
"evidence": "证据来源"
}
]
```
### 2. 验证规则
添加实体关系验证：
- 实体ID必须唯一
- 关系中的source和target必须存在于entities中
- 关系类型必须符合预定义列表
- 实体类型必须符合预定义列表
### 3. 与知识库整合
提取的实体关系可用于：
- 构建知识图谱
- 支持图检索
- 发现新的基因-表型关联
- 跨物种比较分析
---
## 总结
| 方面 | 当前70+维 | 增强版建议 |
|------|-----------|------------|
| **实体类型** | 3种 (gene/domain/database) | 30+种 (基因、蛋白、物种、表型、处理、代谢物、过程等) |
| **关系类型** | 未预定义 | 40+种 (调控、包含、表达、参与、进化、互作等) |
| **属性完整性** | 基础 (name, type, species) | 丰富 (id, symbol, position, confidence, evidence等) |
| **验证机制** | 无 | 有 (唯一性、类型检查、引用完整性) |
| **应用场景** | 信息提取 | 知识图谱构建、图检索、通路分析 |
**建议**: 采用**方案1**（扩展现有字段），保持向后兼容的同时增强实体关系表达能力。
