Construction of Electric Power Meta Knowledge Graph Based on Electric Power Industry Terminology

Meta Knowledge Graph is mainly a knowledge graph formed by the most basic concept entity and its synonymous relationship, which is the most direct entry to show the basic knowledge of the industry. However, due to the complexity of its data sources and the lack of data description specification, it has always been a research difficulty. Based on the analysis of big data characteristics of the power industry and SG-CIM data characteristics of the power company, this paper takes power basic terms as the entrance, crawls complete term entries from the network, obtains entities and synonyms by parsing content, and forms association relationship, and then uses graph database and programming tools to solve the technical problems of Meta Knowledge Graph storage and user interaction. It provides a practical method and technical scheme for the construction of electric power meta knowledge graph.
