A recommendation system based on collaboration, including: an edge system module, a collaboration center system module, and a target system module, and the edge system module, the collaboration center system module, and the target system module are connected in sequence; the edge system module collects and stores user information and sends it to the collaboration center The system module provides the required specific user information; the cooperation center system module responds to the cooperation request of the target system module, sends a cooperation request to the edge system module, and performs inconsistency elimination and reasoning fusion on the user information, and outputs the required information to the target system module. Specific user data; the target system module provides a personalized recommendation service to the user, and initiates a collaboration request to the collaboration center system module during a cold start. The present invention adds a user cooperation mechanism to the recommendation system, and the cooperation center system module completes the cooperation function between multiple recommendation systems, performs fusion processing on the multi-source data of a specific user, and effectively solves the cold start problem in the recommendation system.
