Abstract

The embodiment of the invention discloses a context-based multi-round dialogue method and device, equipment and a storage medium. The method comprises the following steps: acquiring historical dialogue information to be matched; performing word feature extraction according to the to-be-matched historical dialogue information to obtain a historical dialogue word feature vector; obtaining candidateanswer information; performing word feature extraction according to the candidate answer information to obtain candidate answer word feature vectors; performing local semantic relationship matching according to the historical dialogue word feature vector and the candidate answer word feature vector to obtain a historical dialogue local matching vector and a candidate answer local matching vector;performing matching probability calculation according to the historical dialogue local matching vector and the candidate answer local matching vector to obtain a candidate answer matching probability;and determining matching answer information according to the candidate answer information and the candidate answer matching probability. According to the invention, full matching of the context and the answer is realized, and the matching accuracy of the context and the answer is improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a context-based multi-round dialogue method, device, equipment and storage medium. Background technique [0002] Establishing an intelligent human-computer dialogue system that can interact with humans is an important research direction in the field of artificial intelligence. Dialogue systems can be roughly divided into single-turn dialogue systems and multi-turn dialogue systems. A single round of dialogue usually does not involve contextual information, the system has no memory function, and the rounds are independent from each other. Multi-round dialogue needs to take into account context information. Compared with single-turn dialogue, it is more challenging to implement a multi-turn dialogue system. [0003] At present, there are mainly two methods for modeling multi-turn dialogue systems: generative and retrieval. Generation-based methods usu...
