Embodiment Construction

[0035] The terms "system" and "network" are often used interchangeably herein. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

[0036] The implementation of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0037] figure 1 A simplified schematic diagram of a system architecture to which the embodiment of the application can be applied is provided for the embodiment of the application, as shown in figure 1 As shown, the system architecture may include: a client 11 and a server 12 .

[0038] Among them, the client terminal 11 is used to receive the questi...

Abstract

The embodiment of the invention discloses a question answering method and device, relates to the technical field of semantic understanding and aims to solve the problem that accurate semantic matchingcannot carried out on questions of users by servers due to various input modes of the users. According to the specific scheme, the method comprises the steps of receiving a question input by a user and obtaining keywords of the question; obtaining a candidate question-and-answer pair set from pre-stored question-and-answer pairs according to the keywords, wherein the candidate question-and-answerpair set comprises at least one candidate question and an answer corresponding to each candidate question; calculating the topic similarity between the question and the candidate question and determining the candidate question with the highest topic similarity, in at least one candidate question, as the target question; and returning the answer to the target question to the client. When the method disclosed by the embodiment of the invention is applied to a question answering system, the accuracy of semantic matching can be increased.

Description

technical field [0001] The embodiments of the present application relate to the technical field of semantic understanding, and in particular to a question answering method and device. Background technique [0002] With the development of natural language processing and artificial intelligence related technologies, different types of question answering systems have been derived. Question answering systems generally include question analysis (semantic analysis), document fragment retrieval and answer extraction. Among them, problem analysis, that is, analyzing the user's intention, is still a key problem in this field. [0003] In the prior art, the question answering system may include a client and a server, and the question answering process is: after the user inputs a question (Query) at the client, the client can carry the question in the query request and send it to the server, and the server Then, through semantic matching, the question that the user wants to know can b...
