Abstract

The invention discloses a method and a neural network system used for a man-machine conversation, and user equipment. The method used for the man-machine conversation comprises the following steps that: carrying out vectorization on a natural language problem and a knowledge base; through vector computation, obtaining an intermediate result vector which is based on the knowledge base and expresses similarity between the natural language problem and a knowledge base answer through vector computation; and according to a problem vector and the intermediate result vector, carrying out computation to obtain a correct natural language answer based on facts. By use of the method provided by the invention, the conversation and the questions and answers based on the knowledge base are combined, natural language interaction can be carried out with users, and on the basis of the knowledge base, the natural language answer based on the facts can be given.

Description

technical field [0001] Embodiments of the present invention relate to the computer field, and more specifically, relate to a method for man-machine dialogue, a neural network system and user equipment. Background technique [0002] With the rapid development of mobile Internet and smart terminals, the application of man-machine dialogue is becoming more and more extensive. Major Internet companies have also launched their own smart assistants, such as Apple Siri, Google Now, Microsoft Cortana, Facebook M, Baidu Dumi and Microsoft Xiaobing, etc. Current smart assistants are able to hold simple conversations with people and complete some basic tasks. The technology related to intelligent assistants still needs to be continuously developed and improved, and it will develop in a direction that is more anthropomorphic, knowledgeable, and able to complete more complex tasks. [0003] Human-machine dialogue involves a series of technologies, such as: speech recognition, natural l...
