The invention provides a power operation and maintenance information knowledge graph construction method. A deep learning algorithm is introduced in construction of a power field knowledge graph; andtwo major machine learning tasks of named entity identification and entity relationship extraction are adopted for solving two difficult problems of knowledge unit extraction and knowledge unit relationship extraction. The effective utilization of power data is improved; the hidden value of the data is exerted; the intelligent application level of a power network is improved; and based on knowledge representation of the knowledge graph, a low-dimensional and mutually isolated information display mode in the past is changed, and association among power knowledge is presented more intuitively. Apower information operation and maintenance system knowledge library is constructed; historical operation and maintenance data is converted into knowledge; online autonomous consultation and problemsolving of a user are supported; intelligent question and answer are realized; the operation and maintenance efficiency is improved; important values are exerted in power network operation and maintenance work; and based on this, a power information operation and maintenance field knowledge graph optimization storage technology is finished.

Disclosed in the invention is a keyword knowledge management system comprising a kernel keyword information base, a keyword operation management system, a keyword classification management module, a keyword splitting management module, a keyword training management system, a keyword expansion management system and a keyword examination management system. The kernel keyword information base consists of a keyword base, a knowledge point base, a knowledge unit base and a vocabulary library; and the keyword base includes a keyword material and a keyword question bank. The kernel keyword information base is connected with the keyword operation management system, the keyword classification management module, the keyword splitting management module, the keyword training management system, the keyword expansion management system, and the keyword examination management system and provides a data support for all systems and modules.
