Knowledge Graph Ontology Construction of Engineering Support Action

针对工程保障行动领域存在数据格式不统一、缺少规范化标准、不利于信息传输与共享的实际问题，本文提出了一种工程保障行动知识图谱本体构建原则、方法。首先概述了本体构建基本概念，提出了适合本领域本体构建的原则及“五步法”；其次在系统梳理工程保障行动领域相关资料的基础上，对本体构建的主要过程进行了重点阐述；最后应用Protégé工具创建本体，形成了领域知识图谱并进行了可视化展示和实例化应用。本文对于研究基于知识图谱的工程保障行动智能化辅助决策具有一定的指导意义。Aiming at the practical problems in the field of engineering support action, such as inconsistent data format, lack of standardized standards, and unfavorable information transmission and sharing, this paper proposes a principle and method for constructing the ontology of knowledge graph of engineering support action. Firstly, the basic concepts of ontology construction are summarized, and the principles and ‘five-step method’ suitable for ontology construction in this field are proposed. Secondly, on the basis of systematically sorting out the relevant data in the field of engineering support action, the main process of ontology construction is elaborated. Finally, the Protégé tool is used to create the ontology, form the domain knowledge graph, and visualize and instantiate the application. This paper has certain guiding significance for the study of intelligent decision-making of engineering support action based on a knowledge graph.
