Construction Of Knowledge Graph Of Jilin Based On Geographic Ontology

There are massive archival data in the geography of surveying and mapping industry,which provides important guarantee for the national economy and social development.At present,the sort of archives in various industries is paid more attention by the academics and nation.Efficient storage and retrieval systems for archival data must be built in order to make effective use of those data.In this paper,the ontology modeling method is used to analyze and modeling,the spatial and hierarchical relationship model of geographic ontology is put forward and the OWL language is used for formal representation of two relationship models and to establish the ontology relation model of computer language,and then the ontology reasoning mechanism is studied on this basis.The reasoning model of geography ontology in example area Jilin 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,combining the powerful graphic representation ability of graph database,the knowledge map of geographical ontology in Jilin area is constructed.Construction of knowledge map abnormal complicated special geographical industry makes,it is different from the common knowledge map,map relation between nodes should not only include the semantic relation,but also consider the geographic domain specific topology and direction of spatial relations.This paper will build the knowledge map ontology modeling method into the geographic ontology in the industry,various relation model and knowledge map features highly fit,to solve geography industry knowledge map construction provides a solution,and provides some new ideas for the construction of knowledge map in other industries.
