Abstract

The invention discloses a method and device for constructing and using a knowledge model of a conversation system, wherein a method for constructing a knowledge model of a conversation system includes: abstracting at least one subject associated with the knowledge point from the knowledge point in the conversation system; The at least one topic constructs a system topic tree; based on the system topic tree, an association relationship between knowledge points is determined; a conversational system knowledge model is constructed at least based on the system topic tree and the association relationship between each knowledge point. The method of this embodiment abstracts the knowledge points into at least one topic, then uses the topic to construct a topic tree, and then determines the association relationship between the knowledge points according to the topic tree, and then a conversational system knowledge model can be constructed for subsequent heuristics. During the session, questions or answers are recommended to the user, so that questions or content that are more in line with the user's interests can be recommended to the user.

Description

technical field

[0001] The invention belongs to the technical field of conversational systems, and in particular relates to a method and device for constructing and using a knowledge model of conversational systems. Background technique

[0002] In related technologies, in general conversational system application scenarios, such as smart speakers, smart TVs, including current in-vehicle equipment, etc., when the user says a question, the intelligent customer service automatically asks and answers questions and dialogues, the basic process of such a system. It receives a question from the user or a sentence said by the user, and then does some processing in the system to give the user a reply.

[0003] Heuristic conversations keep conversations going by capturing some of the connections behind the questions.

[0004] In the process of realizing the present application, the inventor found that the existing products or technologies are mainly heuristic conversations based on ...
