Method and device for recalling standard questions according to user questions

Abstract

The embodiment of the invention provides a method and device for recalling standard questions according to user questions, and the method comprises the steps: carrying out the word segmentation of a current user question, and obtaining a word segmentation set corresponding to the current user question; taking the word segmentation set as the input of a pre-trained first convolutional neural network CNN model, and obtaining a first sentence representation vector of the current user question through the output of the first CNN model; obtaining each second sentence representation vector corresponding to each standard question generated according to a pre-trained second CNN model; determining a recalled standard question sentence according to the first sentence representation vector and each second sentence representation vector; wherein the first CNN model and the second CNN model are used as feature extractors in a deep structure semantic model DSSM model, and are obtained by training the DSSM model. The standard questions can be efficiently recalled according to the user questions, and the recalled standard questions have a large probability to meet the requirements of users.

Description

Technical field [0001] One or more embodiments of this specification relate to the computer field, and more particularly to a method and device for recalling standard questions based on user questions. Background technique [0002] In the scenario where the customer service robot answers the user’s question, for the situation where the user’s question tends to be colloquial and the user’s request cannot be clarified, multiple standard questions can be recalled from the knowledge base based on the user’s question, and the user can follow the above multiple standards Select the standard question that meets the user's requirement in the question. [0003] In the prior art, when the standard question is recalled based on the user's question, there are often problems that the time delay is large and the recalled standard question does not satisfy the user's request. [0004] Therefore, it is hoped that there will be an improved solution that can efficiently recall the standard question a...
