Abstract

The invention discloses a knowledge graph-based topic transfer method, a controller and a storage medium. The topic transfer method based on the knowledge graph comprises the steps of identifying voice data input of a user; understanding semantic information of the voice data of the user; matching the difference sum of front and back semantics of the semantic information of the user to prepare for subsequent dialogues, including maintaining a knowledge graph, maintaining dialogue states and sorting candidate actions; forming dialogue information; and synthesizing the dialogue information into an audio signal and outputting the audio signal. The topic transfer method based on the knowledge graph can achieve a coherent effect of information topic switching.

Description

technical field [0001] The present invention relates to the field of machine learning, in particular to a topic transfer method based on a knowledge graph, a controller and a storage medium. Background technique [0002] There are various technologies for implementing chatbots, but they are divided into End-to-End mode and Pipeline mode from the perspective of the entire application system architecture. Among them, in the Pipeline mode, from Input->NLU->DM->NLG->Output, a dialogue passes through the system from the input like a pipeline, and finally the answer is output to the user. Pipeline is very flexible, highly interpretable, and easy to implement. Each module can be replaced by different technologies, and modules can share the results of the previous round through parameter passing. But its disadvantage is that it is not flexible enough, each module is relatively independent, it is difficult to jointly optimize, and the errors between modules will accumula...
