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 search method, device and electronic equipment based on artificial intelligence, wherein the search method based on artificial intelligence includes: obtaining an input query statement; segmenting the query statement to obtain a word segmentation sequence composed of multiple word segmentation; The sequence is structurally analyzed to generate a text structure; based on the text structure, the word segmentation sequence is analyzed intellectually to generate semantic analysis results; according to the text structure and semantic analysis results, the corresponding understanding results of the query sentence are determined. The artificial intelligence-based search method, device, and electronic device in the embodiments of the present invention obtain text structure and semantic analysis results by performing structural analysis and knowledge-based analysis on query sentences, thereby determining the corresponding understanding results of query sentences and reducing search results. false recall, improve accuracy, and meet user needs.

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...
