基于航天装备数据的知识图谱体系研究

Research on Knowledge Graph System Based on Space Equipment Data

知识图谱实现了知识以图的结构形式关联链接,从而实现对零散知识进行组织;三元组表征是较成熟的知识图谱构建和表征方法;航天装备体系数据的多源性和异构性等特点对知识的组织和应用提出了新的要求,知识图谱是解决航天装备数据应用的有效方法;对知识图谱构建和应用方法进行了研究,在深入分析三元组知识图谱构建方法的基础上,结合航天装备在役考核的实际应用,提出一种基于航天装备数据的知识图谱体系构建技术,以及基于知识图谱的分析评估方法;自主设计研制了航天装备在役考核综合评估系统,通过航天装备体系在役考核模拟任务对该方法的有效性进行验证;系统运行结果表明方法可以有效的对航天装备知识体系进行组织、挖掘和应用,从而实现综合应用与评估。

Knowledge graph is an effective method to organize scattered knowledge using graphic connection.Triples characterization is a mature method to construct and represent the knowledge graph.The heterogeneity and multi-source of system data of the space equipment put forward new requests to the knowledge organization and application.Knowledge graph is an effective solution to apply the space equipment data.The knowledge graph construction and application methods are analyzed deeply,and a knowledge graph building technology based on the space equipment data is proposed,which is as the foundation of a comprehensive evaluation method.Considering the practical application in in-service inspection of the space equipment,a comprehensive evaluation software system of in-service inspection of the Space Equipment is designed and applied to validate the effectiveness of the method under the simulation in-service inspection task.The operation results of the system show that the proposed method can organize,excavate and apply the data of the space equipment knowledge system effectively,and realized the comprehensive application and evaluation of the system.
