Abstract

The invention discloses a keyword weight determination method and device and computing equipment, and the method comprises the steps: determining the actual search frequency of each keyword in a keyword set according to a search log; calculating a first ratio of the actual search frequency of the keyword to the set search frequency of the keyword; and determining the weight of the keyword according to the first ratio, the weight being negatively correlated with the first ratio.

Description

technical field [0001] The invention relates to the technical field of Internet search, in particular to a keyword weight determination method, device and computing device for query rewriting. Background technique [0002] Query rewriting (Query Rewrite, QR) refers to rewriting the search term input by the user into one or more keywords similar to the search term, and then the search engine searches according to the rewritten keywords. Nowadays, many machine learning methods (such as deep semantic models, etc.) can rewrite dozens or hundreds of similar keywords. Due to performance impact, only a few words can be selected as the final rewriting result. [0003] For example, in an e-commerce search advertising scenario, advertisers purchase keywords for their advertising products on the e-commerce platform, which can also be called bid-words, and the e-commerce platform creates an inverted index of bid words. When the keyword (search word) searched by the user exactly matches...
