Construction method and application of radar knowledge graph
The unstructured textual information describing radar and its attributes is scattered all over the In-ternet.The information is abundant,but the data formats are diverse,so it is difficult to directly process and ana-lyze them.Constructing radar knowledge graph helps effectively solve the problem.Therefore,this paper first sorts out the process of constructing radar knowledge graph,and then combines with the characteristics of radar domain and simultaneously refers to the seven-step method to construct the ontology layer of radar knowledge graph.Finally,the paper uses the Internet text corpus as data source to fine-tune the universal information extrac-tion(UIE)model,with the knowledge extraction completed,and the radar knowledge graph constructed.The ap-plication results show that the constructed radar knowledge graph can provide the function of reference query for the industry personnel and high-dimensional portrait of the combat platform equipped with radar,and meanwhile,can be further developed as the underlying database to support the completion of the upper layer application.
