方案价值

大模型驱动语义搜索与传统搜索相比，语义理解泛化能力强，LLM带给了搜索优化新范式。

搜索增强生成RAG成为解决大模型落地中幻觉、实效性、私域知识融合等问题的最通用技术方案。

组件功能

智能文档解析

用于文档内容解析，支持PDF、JPG、DOC、TXT、XLS、PPT等文档格式，可解析出文档版式、位置坐标、表格结构、图片等内容。

文档切分

支持自动分段，长度分段，层次分段，且支持自定义规则拆分。

搜索规划

利用LLM技术的Query分类、多轮改写、复杂查询分解。

结果生成图文并茂

引用生成、插图点位生成，支持溯源和输出图文并茂。

文本向量模型

支持将文本转化为用数值表示的向量形式，用于语义检索。

文本精排模型

可更加精准找到相关文本，不同于向量模型输出向量，直接计算query和doc的相关性更加准确，可用于对向量召回结果的重新排序。

向量检索

GuassDB向量数据库的向量检索特性，支持根据文本的向量的相似度进行召回。
