Abstract
A method, apparatus and system for generating recommendations of items to users. Ratings of items made by users are collected (1:1). User behaviour information is also collected (1:2). Then correlations in ratings are obtained (1:3) and similarities in user behaviour amongst the users are obtained (1:4). Thereafter, an item for recommendation to a user is identified (1:5), based on both the correlations in ratings and on the similarities in user behaviour amongst the users and the item is recommended to the user (1:6).

13. An apparatus configured to identify items for recommendation to a user and recommend said items to said user, said apparatus comprising:
-
a collecting unit configured to collect ratings of items made by users and to collect user behavior information; an obtaining unit configured to obtain correlations in ratings by computing the correlations and to obtain similarities in user behavior amongst the users by computing the similarities, by clustering similar users together using machine learning techniques; an identifying unit configured to identify an item for recommendation to a user, based on both the computed correlations in ratings and on the computed similarities in user behavior; and a recommending unit configured to recommend said item to said user. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A system configured to find an item or items for recommendation to a user, said system comprising:
-
a first database storing data, related to ratings of at least one of items and users; a second database storing dynamic user data, related to user behavior information; an apparatus configured to retrieve ratings of items or users from said first database and compute correlations in ratings; an apparatus configured to retrieve user behavior information from said second database and to compute similarities in user behavior amongst the users by clustering similar users together using machine learning techniques; and an apparatus configured to retrieve computed similarities in user behavior amongst users, to retrieve computed correlations in ratings, and to identify an item or items for recommendation to a user based on both the computed correlations in ratings and the computed similarities in user behavior. - View Dependent Claims (24)
