Search sorting method and device, computer equipment and storage medium

Abstract

The invention relates to a search sorting method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a search statement and corresponding to-be-sorted recall statements; vectorizing the search statement and each to-be-sorted recall statement to obtain a search statement vector and each to-be-sorted recall statement vector, and calculating the similaritybetween the search statement vector and each to-be-sorted recall statement vector to obtain each similar feature; performing text matching based on the search statement and each to-be-sorted recall statement to obtain each text matching feature; calculating each self-attention matrix corresponding to the search statement and each to-be-sorted recall statement, and performing calculation based onthe self-attention matrixes to obtain each interaction feature; based on the text matching features, the similarity features and the interaction features, calculating the correlation degree between the search statement and each to-be-sorted recall statement; and obtaining a sorting result of each to-be-sorted recall statement according to the correlation degree. By adopting the method, the accuracy of the sorting result can be improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a search and ranking method, device, computer equipment and storage medium. Background technique [0002] With the development of search engine technology, search ranking technology has appeared. In search engines, it usually includes two steps of recall and sorting. Search ranking technology is to sort the recalled results and return them to users to better display the search results. As a result, it is convenient for users to click. [0003] However, the current search ranking technology usually uses the similarity between the search sentence and the recall sentence for ranking. However, this method of using similarity for ranking has the problem of low ranking quality of recall results. Contents of the invention [0004] Based on this, it is necessary to provide a search and ranking method, device, computer equipment and storage medium capable of improving th...
