Dynamic dialogue state diagram learning method, device and system and storage medium

The invention discloses a dynamic dialogue state diagram learning method, device and system and a storage medium. The method comprises the steps of obtaining a representation of a current dialogue utterance; performing enhancement processing on the representation of the current dialogue utterance; wherein the enhancement processing comprises structured enhancement representation and unstructured enhancement representation; according to the representation of the current dialogue utterance, generating a dialogue state diagram, and adding a new node corresponding to the new dialogue utterance into the dialogue state diagram so as to dynamically update the dialogue state diagram; and based on the updated dialogue state diagram, determining the state representation of the whole dialogue. Aiming at the characteristics of multiple rounds of dialogues, the dialogue state diagram is dynamically generated and updated, the representations can be generated for the dialogue words, the dialogue state diagram and the repres
