Knowledge graph construction method and device

Abstract

The invention discloses a knowledge graph construction method and device, and the method comprises the steps: obtaining a first electric power corpus from electric power data; extracting a plurality of entities, a plurality of domain ontologies and a plurality of association relationships from the first electric power corpus by utilizing a pre-trained semantic analysis model, wherein the association relationships comprise one or more of an association relationship among the plurality of entities, an association relationship among the plurality of domain ontologies and an association relationship among the entities and the domain ontologies; for each proposed entity, obtaining a first knowledge graph of the entity according to the association relationship between the entity and other entities and the association relationship between the entity and each domain ontology; combining and splicing the first knowledge maps of the plurality of entities to obtain a second knowledge map; and forming a display path in the entity, the domain ontology and the association relationship in the second map, and displaying according to the display path based on the display of the second knowledge map.According to the invention, the user experience of employees can be improved.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a method and device for constructing a knowledge graph. Background technique [0002] With the continuous advancement of the reform of the electric power system and the increasing attention of the whole society to electric power, the difficulty of the electric power industry is also increasing rapidly, which has also brought great pressure on the cultivation of electric power talents. [0003] Practitioners in the field of electric power use Internet search engines to conduct customized searches and visual searches according to individual needs, so as to learn corresponding professional knowledge and organize relevant materials. [0004] However, the knowledge structure of the electric power industry is complex. Internet search engines usually only display the relevant content links of the searched terms, which cannot quickly reflect other knowledge dimensions...
