Abstract

The invention discloses a knowledge graph construction method and device. The method comprises the steps that an ontology of a target knowledge graph is determined, with the ontology being composed of entities and the relation between the entities; according to the ontology, target entities and target relations among the entities are extracted from the target data, and the target entities are at least used for representing names of all stations in the power grid and operation states and maintenance information of all the stations; based on the target entities and the target relations, a target knowledge graph is obtained, wherein the entities in the target knowledge graph are at least used for representing the name of each site in the power grid and the operation state and maintenance information of each site, and the relations between the entities in the target knowledge graph are at least used for representing the association relations between the sites. The technical problem that the knowledge graph is not easy to construct due to the fact that the power grid sites and the data types associated with all the sites are complicated is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a method and device for constructing a knowledge map. Background technique [0002] In order to better respond to the needs of power supply guarantee for major events, large-scale and important power guarantee work will usually carry out the construction of a coordinated power supply guarantee platform, making full use of modern information means to establish a set of intelligent command systems covering all majors and units to achieve unified command throughout the process , online monitoring, data sharing, rapid response and collaborative processing. [0003] The power supply guarantee platform for major events needs to integrate and integrate all kinds of data of all elements of power guarantee, and analyze and refine the information of these elements, so as to provide smart decision-making technologies such as smart customer service for power guarantee, intelligent info...
