<p dir="auto">GraphRAG 是微软提出的图增强 RAG，解决了传统 RAG 的全局理解问题。</p>
<p dir="auto"><strong>传统 RAG 的问题：</strong></p>
<ul>
<li>只能检索局部信息</li>
<li>无法回答"全局性"问题</li>
<li>缺乏实体间关系理解</li>
</ul>
<p dir="auto"><strong>GraphRAG 的创新：</strong></p>
<ol>
<li>构建知识图谱（实体+关系）</li>
<li>社区检测（Leiden 算法）</li>
<li>多层级摘要</li>
<li>全局+局部检索结合</li>
</ol>
<p dir="auto"><strong>效果</strong>：</p>
<ul>
<li>全局性问题准确率提升 50%+</li>
<li>适合大型文档库</li>
<li>构建成本较高</li>
</ul>
<p dir="auto"><strong>工具</strong>：微软开源的 graphrag 库</p>
