User attribute tags include user name, gender, height, etc., and the weight will be higher at the algorithm layer. Short-term interest tags include such as browsing the information of the product bed, you can never pay attention to it after buying it, and the weight of the algorithm model layer will quickly decay according to time changes. Long-term interest tags include such as entertainment programs-...
