Abstract
本发明公开了一种基于langchain框架的医疗知识库的构建方法及系统，通过同时采集结构化与非结构化医疗数据，打破数据来源壁垒，汇聚分散数据；预处理使不同格式数据规范一致，便于在同一知识库框架处理，解决了数据缺乏整合与统一管理的问题；基于综合考虑多维度因素的医疗知识相似度计算公式进行知识融合，深入理解语义信息，挖掘知识关联，合并相似知识，消除冗余矛盾，弥补了无法理解语义和关联的缺陷；基于医疗知识图谱，结合langchain框架构建查询推理逻辑，其强大语言处理和链式调用能力能准确理解查询意图，快速精准检索推理，生成规范答案，还可与更新机制结合，实时动态融合新知识，提升知识库的时效性和实用性。
