Geographic knowledge association indexing and retrieval method based on hierarchical division of graph network

The invention relates to the technical field of information retrieval, in particular to a geographic knowledge association index and retrieval method based on graph network hierarchical division, and aims to construct a geographic knowledge association index method from an object relationship perspective by comprehensively analyzing an association relationship of geographic knowledge. By analyzing query requirements of geographic knowledge based on an object relation perspective, a corresponding association query algorithm is designed according to an index structure, so that different types of association queries can be effectively met. The problems existing in current geographic knowledge access are effectively solved, and the novel geographic knowledge association indexing method can lay a solid foundation for subsequent scene data scheduling, geographic calculation, complex geographic analysis application and the like. 本发明涉及信息检索技术领域，具体来说为一种基于图网络层次划分的地理知识关联索引与检索方法，通过全面解析地理知识的关联关系，从对象关系视角出发构建地理知识关联索引方法。通过分析基
