Designed with EdrawMax, this template illustrates the workflow of an e - commerce product recommendation system. A “Buyer” initiates an “Initialization of User Query.” This query interacts with the “User Profile Database,” which is updated by “Ratings and Retaining of Item.” Simultaneously, a “Seller” registers a product. The system then enters “Recommendations List Computation,” which involves “Content Extraction” from the “Product Database.” This is followed by “Query Item Selection” and “Recommendation Rankings.” The processed information culminates in the generation of a “Recommendations List.” This diagram effectively showcases the data flow and computational steps involved in providing personalized product recommendations in an e - commerce setting.
