Problems solved by technology

[0004] In related technologies, platforms such as portal websites, news applications, and search engines conduct searches based on keywords in the input search sentences. However, in many application scenarios, the search sentences entered by users are not standardized, and there may be no words in the search sentences. Does not contain the keywords corresponding to the entities to be retrieved. Therefore, the search results obtained by searching based on keywords do not match the user's query intention, and the retrieval performance is not high

Abstract

The invention discloses an artificial intelligence-based query intention prediction method and apparatus. The method comprises the steps of analyzing a query intention of an original retrieval statement through log information of interaction of a user and a search engine; and training an intention classification model according to a corresponding relationship between the original retrieval statement and the query intention, thereby predicting a query intention corresponding to the retrieval statement input by the user according to the intention classification model. According to the method, the query intention of the user is accurately analyzed, so that a retrieval result conforming to the query intention of the user can be conveniently provided for the user and the retrieval performance is improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an artificial intelligence-based query intent prediction method and device. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It 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 responds in a manner similar to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural language processing and expert systems, etc. Among them, the most important aspect of artificial intelligence is speech recognition technology. [0003] With the development of Internet technology, users are b...
