Abstract:Aiming at the application requirements of military detection and recognition,research on knowledge graph (KG) construction and related application technologies wascarried out. The application potential and core value of knowledge graph were analyzedemphatically, including a new target characteristic data management mode, a new technicalapproach to target detection and recognition, a new method to construct cognitiverelationship of complex battlefield situation, a new digital form of product design andtechnical planning. The research results provide practical and feasible solutions for the fullutilization of domain data resources and the development of new equipments
