Abstract

The invention discloses a method and device for an expansion query. The method comprises the specific steps of on the basis of an image relevant to a target query, clicking a log to calculate an imageclicking characteristic vector of the target query; on the basis of an image of the target query, clicking the characteristic vector, searching for a similar query of the target query in a preset query set, and obtaining a candidate expansion query set of the target query; matching the target query and all candidate expansion queries with notional words and determiners in a knowledge graph to extract notional words and determiners of the target query and all the candidate expansion queries; combining with the knowledge graph to expanding the notional words and the determiners of the target query and all the candidate expansion queries; matching expansion results of the notional words and the determiners of the target query and all the candidate expansion queries to determine the expansionquery of the target query from the candidate expansion query set. The method and device for the expansion query improve the richness of the expansion query.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for expanding query formulas. Background technique [0002] With the development of Internet technology, more and more Internet data are generated. Search engines are an important way for users to obtain Internet data. The user inputs the query keyword, and the search engine generates a query formula (query) based on the keyword and retrieves the information required by the user from the massive Internet data. [0003] Usually the search engine can expand according to the query keywords entered by the user, recommend some highly relevant query formulas, or directly expand the query formula to the highly relevant query formula for query, so as to efficiently provide users with the information they need . Existing query expansion methods are usually based on a pre-set query database, in which e...
