基础地理实体关系的知识图谱构建方法研究

Research on Knowledge Graph Construction Method of Basic Geo-entities Relationships

针对新型基础测绘中构建地理实体关联关系的问题,提出一种基础地理实体关系的知识图谱构建方法,利用江苏省基础地理实体库作为实验数据,结合本体构建、知识抽取、知识图谱存储和语义网表示等关键技术,实现了基础地理实体知识图谱的构建与应用。实验结果表明:与传统的库表属性关联方法相比,该方法降低了地理实体关联关系构建的复杂度,串联地理实体多源异构数据,实现结构化、半结构化数据的高效存储与快速索引,满足了新型基础测绘“一库多能,按需组装”的需求,为实景三维中国的建设提供了可靠、高效的服务基础。

Aiming at the problem of constructing the association relationship of geo-entities in the new basic surveying and mapping,we pro-posed a knowledge graph construction method of basic geo-entities relationship.Taking the geo-entity database of Jiangsu Province as experimen-tal data,we used the technical methods of ontology construction,knowledge extraction,knowledge graph storage and semantic web representa-tion to realize the construction and application of basic geo-entity knowledge graph.The experimental results show that compared with the tradi-tional database table attribute association method,this method reduces the complexity of geo-entities association relationship construction,con-nects multi-source heterogeneous data of geo-entities in series,realizes efficient storage and rapid indexing of structured and semi-structured data,meets the needs of“one library with multiple functions,and assembles on demand”,and provides a service foundation for the real scene 3D China.
