Problems solved by technology

Therefore, the existing technology has the following disadvantages: 1) The vertical dialog flow configured by static rules is relatively fixed, and can only complete the clear logic in the rules, which is not flexible enough; 2) Static rules are based on the specific logic of a specific product. settings, do not have the ability to generalize, and cannot apply these rules to other vertical categories and products

Abstract

The invention discloses a behavior management method and device of conversational system based on artificial intelligence. The management method includes that current conversation feature is formed according to current system interaction state, current user state and system behavior sequence, a potential system behavior related to the user is chosen from the system behavior sequence according to the current conversation feature and a system behavior trigger model developed from training, and the device interacts with the user according to the potential system behavior. According to the technical scheme, the potential system behavior in the behavior management method and device of conversational system based on artificial intelligence is determined by the system behavior trigger model and improves flexibility of the conversational system and generalization capability when compared with the current technology in which the potential system behavior is determined by the system behavior trigger rules of static allocation.
