Problems solved by technology

[0004] However, when the existing search engines sort multiple documents related to the query statement, most of them use the text similarity between the query statement and the document as the sorting criterion. The order relationship between the cut words, so there are problems of low sorting efficiency and inaccurate sorting

Abstract

The embodiment of the invention discloses a searching method and device based on artificial intelligence. The method comprises the steps of obtaining at least one candidate document related to a searching sentence; determining a searching word vector sequence corresponding to a segmented word sequence of the searching sentence and determining a candidate document word vector sequence corresponding to the segmented word sequence of each candidate document in the at least one candidate document; executing the step of similarity calculation on each candidate document in the at least one candidate document; selecting a preset number of candidate documents as searching results from the at least one candidate document according to the sequence of the similarity with the searching sentence from large to small. According to the searching method and device based on the artificial intelligence, the candidate documents and the searching sentence are represented into a semantic vector through a neural network model, then according to similarities between a candidate document semantic vector and a searching sentence semantic vector, the candidate document is ranked, and the relevance of the searching results which are called back and the searching sentence input by a user is improved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to an artificial intelligence-based search method and device. Background technique [0002] Artificial Intelligence (AI) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics, language recognition, image recognition, natural language processing and expert systems, etc. [0003] Natural language processing in the field of artificial intelligence is an important direction in the field of computer science and artificial intelligence. It studies various theorie...
