Problems solved by technology

[0004] The sorting algorithm that comes with the search engine analyzes the recommended text as a whole when calculating the correlation between words, which leads to inaccurate calculation of word similarity, which in turn responds to the sorting results; and, search terms and keywords The similarity of word meanings only reflects the shallow association between the search text and the recommended text, and the ranking based on the correlation score between search terms and keywords leads to low accuracy of the ranking results

Abstract

The invention relates to the technical field of artificial intelligence, provides a text sorting method and device, and improves the accuracy of a sorting result through two times of sorting. Specifically, according to the word frequency of at least one search word in a search request in each preset text field of each recommended text and the weight corresponding to a preset document field, the word meaning similarity between the search text and each recommended text is determined, so that the relevancy between the words can better reflect the relevancy between the recommended text main body contents and the search words, the sorting result better meets the search intention of a user when each recommended text is initially sorted according to the similarity of a plurality of word meanings; after initial sorting, a trained target text sorting model is adopted to perform target sorting on the initially sorted recommended texts according to the semantic information among the recommended texts, so that the sorting efficiency of the model is improved. Due to the fact that the semantic information among the recommended texts is utilized during target sorting, the sorted result is more accurate.

Description

technical field [0001] This application relates to the technical field of artificial intelligence, and discloses a text sorting method and device. Background technique [0002] Semantic search is to screen out a limited set of texts that meet the search intent from a massive text set, and display them to users in an orderly manner, and has high requirements for the response speed of online search engines, generally at the millisecond level. [0003] At present, the commonly used text sorting methods are mainly: based on the search words entered by the user, using the inverted text index method, matching multiple recommended texts related to the search words from the original text collection, using the sorting algorithm that comes with the search engine , calculate the correlation scores between the keywords in each recommended text and the search terms, and sort the multiple search texts according to the scores. [0004] The sorting algorithm that comes with the search engi...
