Problems solved by technology

[0004] However, the results of the QU evaluation method have low stability, redundant results, lack of diversity, and cannot well meet the needs of the queryer; compared with the QU evaluation method, the side-by-side evaluation method can overcome the shortcomings of QU evaluation, but then Other drawbacks arise, such as higher evaluation costs, greater evaluation complexity

Abstract

The embodiment of the invention discloses a quality evaluation method, device, server and medium for search results. The method comprises the steps of obtaining at least two search result lists corresponding to target query, wherein different search result lists are obtained according to different search sorting algorithms; dividing the search results in the search result lists according to a listorder to obtain at least one search result group, wherein the search result groups include the search results with the same sorted positions in each search result list; obtaining a rating result of the search result groups from a user, and performing fitting to obtain an evaluation result of the search results of the target query. According to the embodiment, the problems of a high evaluation cost and high evaluation complexity in existing evaluation methods are solved, the evaluation cost and the evaluation difficulty are reduced, and the evaluation efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method, device, server and medium for evaluating the quality of search results. Background technique [0002] For a mature Internet search engine, in order to ensure an excellent user experience, it is necessary to continuously improve the search result ranking algorithm. To judge whether a new search ranking algorithm has achieved the expected effect, it is necessary to scientifically evaluate the quality of search results. [0003] The root of search engines is to find information that meets user needs, which can usually be reflected by the degree of correlation between search results and keywords entered by users, that is, result correlation. Therefore, result correlation is the most important indicator for evaluating search engines . In the process of evaluating the quality of search results of search engines, in order to avoid the problem...
