Abstract

Methods and systems consistent with the present invention provide a recommendation system that uses positive data and/or negative data separately to locate neighbors and provide recommendation to users. Such methods and systems use the data to locate potential neighbors based on users' ratings. Methods and systems consistent with the present invention calculate affinity values between the user and potential neighbors located to determine whether the potential neighbor's ratings are closely related to that of the user's ratings. If a user and a potential neighbor have an affinity greater than a predetermined threshold, that neighbor is considered close enough to the user to provide a recommendation for various items. Affinity values are calculated from a series of affinity equations available to the recommendation system.
