Abstract

The invention discloses a method and device for constructing and using a knowledge model of a session system, and the method for constructing the knowledge model of the session system comprises the steps: abstracting at least one theme associated with a knowledge point from the knowledge point in the session system; constructing a system theme tree based on the at least one theme; determining an association relationship among the knowledge points based on the system topic tree; and constructing a session system knowledge model at least based on the association relationship between the system topic tree and each knowledge point. Knowledge points are abstracted into at least one topic.. A topic tree is constructed by utilizing a topic, the association relationship among the knowledge pointsis determined according to the topic tree, and then the knowledge model of the session system can be constructed for recommending questions or answers to the user in the subsequent heuristic session process, so that questions or contents which more accord with the interest of the user can be recommended to the user.

Description

technical field [0001] The invention belongs to the technical field of conversation systems, in particular to methods and devices for constructing and using knowledge models of conversation systems. Background technique [0002] In related technologies, in general conversational system application scenarios, such as smart speakers, smart TVs, including current vehicle-mounted devices, etc., when the user asks a question, the smart customer service automatically answers the question and dialogue. 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] A heuristic session keeps the session going by capturing some of the connections behind the question. [0004] In the process of implementing the present application, the inventor found that the current existing products or technologies are mainly heuristic conversations based on topics or scenarios, wi...
