Abstract

The present invention provides a keyword retrieval method, device, medium and electronic equipment. The keyword retrieval method includes: converting one or more keywords into corresponding one or more unit word vectors; according to the converted One or more unit word vectors obtain a representative word vector; Calculate the similarity between the representative word vector and each unit word vector in the built word vector library, wherein the word vector library includes a plurality of unit word vectors and The words corresponding to each unit word vector; the words corresponding to one or more unit word vectors with the highest similarity with the representative word vector in the word vector library as the retrieval result. The present invention converts keywords into corresponding unit word vectors and uses the quantified unit word vectors to perform similarity calculations, making the retrieval process simple; in addition, when the user inputs multiple keywords, multiple keyword The average vector or weighted average vector of multiple unit word vectors corresponding to a word is used to generate a representative word vector for retrieval, which can accurately obtain retrieval results.

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...
