Research of Electrical Safety Knowledge Graph Construction

With the continuous development of the electrical industry, the amount of knowledge about electrical safety is increasing. Electrical safety knowledge can provide effective information reference for electrical industry technicians. At the same time, electrical safety knowledge has the characteristics of various forms and low structure. Knowledge graph is essentially a semantic network based on graph, which represents the relationship between entities and plays a crucial role in knowledge question answering, semantic retrieval and other fields. Aiming at the problems such as the low structure degree of electrical safety knowledge and the difficulty of knowledge acquisition, this paper aims to explore the method of knowledge graph in electrical safety field. In view of the above tasks, this paper mainly carried out the following work: First, this paper attempts to obtain concepts from relevant standard files and complete the construction of domain ontology. Secondly, the ontology relation is extracted from the standard file. Finally, the BiLSTM-CRF model is used to realize named entity recognition.
