Problems solved by technology

Although this method solves the problem of polysemy and synonyms of a word in the traditional method to a certain extent, because it ignores the position information of words in the query text and search entries, it cannot solve the problem of query text and search entries. Differences caused by different order of words, for example: query text 1: "I love Baidu" and query text 2: "Baidu loves me" The vector representations of the two query texts are the same, so they will target the same search item , giving the same ranking score

Abstract

The invention provides a method and a system for sequencing search entries. The method comprises the following steps: expressing an inquiry text into a vector according a word order through a neural network; computing sequencing scores between the inquiry text and the search entries according to the expressed vector through the neural network; sequencing the search entries according to the computed sequencing scores. By adopting the method and the system, search sequencing can be performed under the consideration of matching of polysemy and synonyms and the word order of words, and more accurate sequencing results can be given.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and system for sorting search items. Background technique [0002] According to the query text entered by the user, returning sorted search results to the user is the basis of the search engine system. The calculation of the ranking score between the query text input by the user and the search items to be sorted is the core problem of the search engine system. [0003] The traditional method of calculating the ranking score between the query text and the search item is to calculate the exact matching degree of the words contained in the two strings of the query text and the search item, that is, the similarity of the two text strings. Computes the ranking score between query text and search terms. However, this method of calculating ranking scores based on the degree of literal matching of words does not take into account the polysemy of words and the matchin...
