Construction of Knowledge Graph Based on Geographic Ontology

Here are massive archival data in the geography of surveying and mapping industry, which provides important guarantee for the national economy and social development. Efficient storage and retrieval systems for archival data must be built, in order to make effective use of these data. In this paper, OWL language is used to establish the ontology relation model of computer language, and then the ontology reasoning mechanism is studied on this basis. The reasoning model is educed with open source project Jena inference engine. Then the knowledge map of regional geographic ontology is constructed with the powerful ontology graphical representation ability of graph database. Finally, the search system is developed based on the java language, achieving the required retrieval requirements.
