Problems solved by technology
[0007] (1) The existing user knowledge base constructed by extracting relevant entities from user interaction history cannot identify the same topic, which makes the user model redundant;
[0008] (2) The traditional dialogue model based on template rules or retrieval requires a lot of manual participation and poor flexibility.

The present disclosure provides a cloud platform-based personalized dialogue system and method for a service robot. Among them, the person's personalized dialogue system includes the cloud and the robot terminal, and the cloud includes a user knowledge base for storing user interaction history and user models; the user model is a user model output in real time by the user model building module; the user model building module , which is used to retrieve user interaction history, and use the Twitter-LDA model to mine user-interested topics to construct a dynamic user model; the dynamic user model is superimposed by multiplying user sub-models at different time levels and corresponding proportion factors; An information retrieval module, which is used to use the real-time user model to obtain user information related to the dialogue context from the user interaction history, and initially screen; an end-to-end dialogue generation module, which is used to generate sequence dialogues based on the initially screened user information, through Speech synthesis converts text information into voice information and plays it, completing an interaction between the user and the service robot.
Description
technical field [0001] The disclosure belongs to the field of robots, and in particular relates to a cloud platform-based personalized dialogue system and method for a service robot. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, industrial robots have been widely used in the manufacturing industry. Although the emergence and industrialization of service robots are relatively late, with the development of artificial intelligence technology in recent years, service robots have entered a stage of rapid development. The operation of industrial robots usually requires professional training, and service robots have higher requirements for human-computer interaction due to their expanded application range. In the service robot, the oral dialogue system based on natural language for human-computer interaction greatly improves the e...
