Abstract

Methods, systems, and computer program products may obtain ratings by users for products at time points; for each user and product pair: generate, for a time point, a user neighborhood that includes products rated by that user at or after that time point and a product neighborhood that includes users that rated that product at or after that time point, an individual-based rating of that user for that product at or after that time point being generated based on the user neighborhood, and a crowd-based rating of that product for that user at or after that time point being generated based on the product neighborhood; train a model that processes the individual-based rating and the crowd-based rating for the time point for each user and product pair and to generate a predicted rating of the user for the product of each user and product pair at a current time point.
