Abstract

The invention provides a Chinese dialogue knowledge retrieval method based on a knowledge retrieval graph and a pre-training model in order to solve the technical problem that in the prior art, the performance is poor when topic switching between multiple rounds of dialogues is processed. According to the method, text semantic information is modeled by utilizing a pre-training model, and the relationship between knowledge is modeled by utilizing knowledge retrieval graph structure information, so that knowledge triples related to subsequent replies of a current dialogue can be retrieved more accurately, and subsequently generated knowledge dialogues can better meet topic switching among multiple rounds of dialogues, and a better dialogue effect is obtained.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to the application of natural language processing in man-machine dialogue, and more specifically, to a Chinese dialogue knowledge retrieval method, system, storage medium and computer equipment. Background technique [0002] Natural language processing technology has always been committed to enabling machines to communicate fluently and freely like humans. This is also the original intention of many voice assistants on the market, such as Siri, Xiaodu, etc. While the dialogue is smooth, the dialogue responses produced by it can be rich in knowledge, not just responding to the content of the dialogue. Therefore, when providing training corpus for the machine, in addition to providing the corresponding historical dialogue information, it is also necessary to provide the corresponding dialogue knowledge, so that the machine can generate knowledgeable dialog...
