Problems solved by technology

[0003] However, the above method does not have a deeper understanding of the query, relying on a relatively flat keyword sequence to recall the sorting results, relying on the user's historical behavior to optimize the sorting results, the accuracy rate is not high, and cannot meet the needs of users

Abstract

The invention discloses a searching method and device based on artificial intelligence and electronic equipment. The searching method based on the artificial intelligence comprises the steps of obtaining an input query sentence; segmenting the query sentence to obtain split word sentences composed of multiple split words; conducting structuralized analysis on the split word sentences to generate atext structure; based on the text structure, conducing knowledgeable analysis on the split word sentences to generate a semantic analysis result; according to the text structure and the semantic analysis result, determining an understanding result corresponding to the query sentence. By means of the searching method and device based on the artificial intelligence and the electronic equipment, byconducting structuralized analysis and knowledgeable analysis on the query sentence, the text structure and the semantic analysis result are obtained, thus the understanding result corresponding to the query sentence is determined, erroneous recalling of the searching result is lowered, the accuracy is improved, and the user requirements are met.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an artificial intelligence-based search method, device and electronic equipment. Background technique [0002] For traditional search engines, the understanding of query (query information) is mainly to divide the query into multiple keywords for analysis. Specifically, the query may be segmented first to generate a sequence consisting of multiple keywords, and a certain weight is assigned to each keyword. Then, word segmentation is also performed on the retrieved content (such as an Internet webpage), and a word sequence (term) is generated, and a certain weight is assigned. Calculate the coincidence degree (similarity) of the word segmentation in the two sequences, and calculate the score with the weight at the same time, and obtain a ranking result of pure text relevance. Finally, based on the record of the user's continuous clicking behavior on the or...
