Problems solved by technology

The above-mentioned information retrieval system has certain defects. When processing multiple keywords input by users, it does not take into account the relationship between the semantics of keywords, and only performs simple splicing and text matching, resulting in low accuracy of retrieval results. , resulting in higher requirements for keyword selection

Abstract

The invention provides a keyword retrieval method and device, a medium and electronic equipment. The keyword retrieval method comprises the steps: converting one or more keywords into one or more corresponding unit word vectors; obtaining a representative word vector according to the one or more unit word vectors obtained through conversion; calculating the similarity between the representative word vector and each unit word vector in a constructed word vector library, wherein the word vector library comprises a plurality of unit word vectors and words corresponding to each unit word vector; and taking words corresponding to one or more unit word vectors with the highest similarity with the representative word vectors in the word vector library as retrieval results. According to the keyword retrieval method, the keywords are converted into the corresponding unit word vectors, and similarity calculation is carried out by using the quantized unit word vectors, so that the retrieval process is simple and convenient; furthermore, when a user inputs a plurality of keywords, representative word vectors are generated from the average vectors or weighted average vectors of a plurality of unit word vectors corresponding to the plurality of keywords for retrieval, and a retrieval result can be accurately obtained.

Description

technical field [0001] The present invention relates to the technical field of information retrieval, in particular to a keyword retrieval method, device, medium and electronic equipment. Background technique [0002] At present, the information retrieval system usually works according to the following process: match in the database according to the keywords input by the user, get the matching result and feed it back to the user, where the matching result can be text, image and other information associated with the keyword input by the user links etc. The user can input one keyword at a time or multiple keywords. When the user inputs multiple keywords at one time, the information retrieval system will first splice these keywords, and then match the spliced ​​keywords in the database ( For example, to calculate the text similarity), so as to obtain the matching result. The above-mentioned information retrieval system has certain defects. When processing multiple keywords in...
