Abstract

The invention provides a method, device and equipment for text retrieval and a storage medium, and relates to the field of artificial intelligence such as big data and natural language processing. According to the specific implementation scheme, the method includes using a full-text search engine for obtaining a plurality of candidate texts meeting a retrieval formula; calculating multi-dimensional features of the candidate text according to the keyword of the retrieval formula and the text content of the candidate text; obtaining a correlation score through text similarity operation based on multi-dimensional feature fusion, sorting the multiple candidate texts according to the correlation score, wherein the correlation score is used for representing the text similarity of the candidate texts and the retrieval formula; and according to a preset rule, carrying out secondary sorting and filtering on the plurality of candidate texts to obtain a target text. According to the technical scheme, accurate query and sorting of the texts can be realized semantically, so that the accuracy and efficiency of text retrieval are improved, and the text retrieval experience of a user is improved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular to the fields of big data and natural language processing. Background technique [0002] In related technologies, the technical solution of text retrieval based on retrieval formula can only realize literal text matching, but cannot realize precise retrieval and sorting of text semantically, so that the retrieval results cannot well meet the retrieval needs of users. Contents of the invention [0003] The disclosure provides a method, device, device and storage medium for text retrieval. [0004] According to an aspect of the present disclosure, a method for text retrieval is provided, comprising: [0005] Use a full-text search engine to obtain multiple candidate texts that satisfy the search formula; [0006] According to the keywords of the search formula and the text content of the candidate text, calculate the multi-dimensional features of the candi...
