基础地理实体关系的知识图谱构建方法研究OACSTPCD

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.
