Benefits of technology

This patent is about a system that generates recommendations for items based on user behavior and business objectives. The system analyzes data on users and their interactions with items to determine what they like and what they are looking for in a recommendation. This analysis takes into account things like user preferences, item popularity, and business goals. The system then recommends items to users based on these preferences and objectives. The technical effect is a more effective and efficient recommendation system that can better match users with items that they are likely to like.

Problems solved by technology

However, the typical approach disregards the relationship between the items included in the recommendation list.

Abstract

The method includes determining at least one business objective on which to base a recommendation list for a first item, associating a configurable target with the business objective, the configurable target being based on a goal for a second item, determining at least one business constraint relating the first item with the second item, the at least one business constraint being based on the business objective and the associated configurable target and generating the recommendation list for the first item based on a list of candidate items and the business constraint.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 U.S.C. §119 to Chinese Patent Application 201210536851.9, filed Dec. 12, 2012, titled “CONFIGURABLE MULTI-OBJECTIVE RECOMMENDATIONS”, which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]This description relates to a method, system and computer readable medium for generating constraint based recommendation lists.[0004]2. Related Art[0005]There are many types of recommender systems, including content-based filtering and collaborative filtering. Typically collaborative filtering has two major approaches. The first is a user-based approach and the second is an item-based approach. Typically a recommender system computes a ranking list of items based on their interest to a user. The system suggests top N items of the list to the user, where N is a predefined size of the recommendation list.[0006]However, the typical approach disregards the relationship between the ite...
