Abstract

本发明涉及面向智慧高速的空间语义检索智能体构建方法，基于多源高速交通空间信息数据构建实体分词库；对实体分词库中的各实体，将其不同来源名称、坐标转换为向量，构建向量库；构建智能体工作流：大语言模型获取用户问询信息，基于分词库抽取实体信息，获取实体识别候选集；基于实体识别候选集从向量库提取实体的向量表示，同时基于知识图谱进行实体关系的检索和推理，将实体识别候选集及从向量库、知识图谱获取的信息作为空间检索的背景信息；将背景信息转换为异构引擎调度指令集并调用多维空间查询的动态执行路由图，获取检索结果。本发明的方法可高效处理空间信息检索问题，且能够消除实体识别中的歧义，处理复杂空间查询过程。
