Abstract

The invention provides a question and answer method and device and terminal equipment. The question and answer method comprises the steps of obtaining a user question; obtaining a candidate question set of the user questions according to the user questions; respectively inputting the user question and each candidate question in the candidate question set into a preset sentence vector model to obtain sentence vectors of the user question and each candidate question; according to the user problem and the sentence vector of each candidate problem, determining the candidate problem with the highest similarity with the sentence vector of the user problem in the candidate problem set as a matching problem of the user problem; determining a preset answer matched with the question as an answer ofthe user question, wherein the preset sentence vector model is obtained by training the collected user intention recognition corpus. According to the scheme, the answers to the user questions can be obtained on the premise of not using the question-answer matching model, and the question answers with high accuracy can be obtained by combining the preset sentence vector model.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a question answering method, device and terminal equipment. Background technique [0002] Currently, the QA (Asked Questions) system can be used to analyze the intent of user questions, and return answers matching user questions by searching the question-and-answer knowledge base. The processing framework of a QA system generally includes question semantic understanding, information retrieval and answer generation. [0003] Wherein, when the QA system is used for answer generation, the pre-trained question-answer matching model in the QA system is usually used. And in order to ensure the accuracy of the output results of the question-answer matching model, a large amount of text annotation data is required for training when training the question-answer matching model. However, there are very few question-answer data in some scenarios, so a small amount of text ann...
