Intelligent questioning and answering method and system

Abstract

The invention provides an intelligent questioning and answering method and system. The intelligent questioning and answering system (100) comprises a dialogue engine (101), an analysis module (102), acandidate questioning and answering library (103), a retrieval module (104), a matching module (105) and a reordering module (106), wherein the dialogue engine (101) is used for receiving a questionraised by a user; the analysis module (102) is used for analyzing a user's question; the retrieval module (104) is used for retrieving a questioning and answering pair related to the user's question in the candidate questioning and answering library (103) based on the result of the question analysis of the analysis module (102); the matching module (105) is used for calculating the matching degreevalue between the candidate questioning and answering pair retrieved by the retrieval module (104) and the user's question; and the reordering module (106) is used for comprehensively considering theresulTS obtained by the problem analysis, retrieval and matching, and reorder the candidate questioning and answering pairs according to the service requiremenTS. The dialog engine (101) is further configured to select a reply to the user from the candidate questioning and answering pairs reordered by the reordering module (106).

Description

technical field [0001] The present invention relates to artificial intelligence, more specifically to a robot intelligent question answering method and system. Background technique [0002] The current question-answering robot system is mainly based on the information retrieval framework of search engines, using keywords for retrieval and matching ranking. However, some of the user's questions and the matching question-and-answer pairs in the dialogue are very short, and some need to be answered after semantic understanding. Traditional information retrieval techniques cannot obtain good results for such questions. [0003] Therefore, it is necessary to provide an intelligent question answering system, which can automatically and intelligently answer users' questions through detailed analysis. Contents of the invention [0004] As mentioned above, the purpose of the present invention is to propose an intelligent question answering system, which expands the traditional inf...
