Study on a Novel Knowledge Service Method Based on the Knowledge Graph in the Domain of Substation

Abstract

The development of knowledge management and service enlightens the upgrading of traditional vocational education and work assistance. This work focuses on the field of substation and proposes a novel knowledge service method based on the domain knowledge graph. Specifically, a systematic three-layer knowledge graph is constructed, reflecting the physical entity, specialized knowledge and basic knowledge in substations. Furthermore, a domain model is established to translate the user’s demand into a node set derived from the knowledge graph, and a path model is established to give a sequence of the derived nodes for recommendation. The results have been validated logical and reasonable in different scenarios of learning, training and getting assistance. Taking advantage of the structure and precision of our knowledge graph, more applications can be added into the substation-related services.
