Abstract

The present invention provides a system standard retrieval method and system based on an electric power knowledge base and a readable storage medium, field migration is easy, and the detection efficiency and the coverage rate are improved. The method comprises the steps of 1, extracting keywords of an input power system standard sentence; 2, retrieving in an electric power system standard knowledge base according to the keywords, obtaining entity words corresponding to keyword semantics and associated entity words similar to the semantics, and jointly forming a retrieval keyword base; 3, combining the words in the retrieval keyword library in pairs to form retrieval word groups respectively, and gathering the retrieval word groups to obtain a query word group set; 4, taking words in the retrieval word group as joint query keywords, retrieving related system standard IDs in the electric power system standard knowledge base, and calculating the system standard ID with the highest confidence coefficient as a retrieval result; and 5, retrieving a relational database storing detailed system standard contents according to the system standard ID with the highest confidence coefficient toobtain system standard text data, and outputting the system standard text data.

Description

technical field

[0001] The invention relates to the field of system standard item retrieval in the electric power field, in particular to a system standard retrieval method and system based on an electric power knowledge base, and a readable storage medium. Background technique

[0002] In natural language processing and knowledge retrieval, the retrieval system based on domain knowledge base is an important means of utilizing domain knowledge. It receives natural language questions as the input of the system, and it can directly give accurate and professional information through domain knowledge base retrieval. s answer. The domain knowledge base retrieval system can usually be used as an office assistant in the domain, which provides users with professional domain knowledge retrieval services.

[0003] Retrieval based on knowledge base usually includes two parts: user intent analysis and knowledge retrieval. User intent is usually captured by identifying entities or keyw...
