Ontology concept acquisition method, device and storage medium in the field of civil aviation security

Abstract

The present disclosure relates to an ontology concept acquisition method, device and storage medium in the field of civil aviation safety. The method includes: determining a plurality of first candidate words from a plurality of civil aviation safety texts according to a preset civil aviation safety thesaurus; Multiple civil aviation safety texts, respectively determine the word frequency-inverse document frequency and domain relevance of each first candidate word; according to the word frequency-inverse document frequency and domain relevance, select multiple second candidates from multiple first candidate words from the preset parameter description text, determine a plurality of third candidate words; according to the parameter description text and the decoding library, determine the importance of each third candidate word; Among the third candidate words, at least one fourth candidate word is selected; a plurality of second candidate words and at least one fourth candidate word are determined as ontology concept words in the field of civil aviation safety. The embodiments of the present disclosure can improve the acquisition efficiency and accuracy of ontology concepts in the field of civil aviation safety.

Description

Technical field[0001]The present disclosure relates to the field of civil aviation security, in particular, involving a physical concept acquisition method, device, and storage medium in the field of civil aviation security.Background technique[0002]As a result of effective tools describing the relationship between massive knowledge entities, attributes, attributes, since 2012 Google successfully applied to the search engine, it has been widely used in the academic and industry. Although the research on general knowledge maps at home and abroad is rapidly developing, the number of knowledge maps in the vertical field is less. The domain knowledge map is facing the specific area, based on industry data construction, the complex domain knowledge and knowledge system are displayed by data mining, information processing, knowledge metering, and graphical drawing, can provide all-round, integrity, relational chain. Reference.[0003]The body construction is one of the important links in th...

AI Technical Summary

Problems solved by technology

At present, the methods of manually constructing ontology (such as the skeleton method) are relatively mature and accurate, but it requires domain experts to use experience to construct, and the workload is heavy

[0004] At present, there is no established domain knowledge graph in the field of civil aviation safety, and the research on ontology construction for the field of civil aviation safety is hardly involved.
