Internet-based Knowledge Graph Construction Technology in Air Defense Field

Air defense security is an important part of our military work. In order to solve the contradiction between "data explosion" and "knowledge lack" existing in the field of military air defense, in this paper, we adopt a more scientific way to organize and manage big data, namely, constructing knowledge graph. In this paper, we construct the ontology model of knowledge graph of air defense domain at first. Secondly, we use information extraction technology to sort, extract and clean the open source data on the Internet. Then the data that meet the requirements are added to the knowledge graph. Finally, we use the Neo4j graph database to manage and store the data in the knowledge graph.
