METHODS AND ARRANGEMENTS FOR CREATING CUSTOMIZED RECOMMENDATIONS

摘要

A method and arrangement for creation of a customized recommendation of items in a user device (200) in communication with a recommendation system (202). The recommendation system obtains (2:2a) ratings of items for a public recommendation based on public user data (202a) and obtains (2:2b) attribute- related weight information for said items with item-specific weight values for a plurality of attributes pertaining to user characteristics. The ratings of items in the public recommendation and the weight information are sent (2:3) to the user device which then modifies (2:4, 2:4a) the public recommendation into a customized recommendation by selecting attributes valid for a current user based on said private user data, and applying the weight values of the selected attributes only to the received ratings of items. The non-valid attributes are thus disregarded. Thereby, new item ratings are obtained which have been adapted to the characteristics of this particular user.
