Automatic Construction of Knowledge Graph and Its Application in Electric Power System

The purpose of introducing the knowledge graph (KG) for electric power system is to make full use of the data information carried by the electric power Internet of Things, to describe the concepts, entities, events, and relationships between them in a structured way, so as to provide a more effective organization, management and cognitive ability of the cross-media big data for electrical power industrial chains. This paper firstly proposed an automatic construction of knowledge graph. And then, the detail information in power equipment inspection application was revealed. Finally, the application directions and future challenges of KG technology was discussed.
