SOCIONYMOUS METHOD FOR COLLABORATIVE FILTERING AND AN ASSOCIATED ARRANGEMENT

摘要

A method and an arrangement, e.g. an electronic device, for collaborative filtering suggest placing the users of a service into concealing groups (116) in the name of which the individual users can rate various items available through the service. The users may also select a representation group (118) to represent them in front of the service that further utilizes the gathered ratings for providing the representing groups members with item recommendations.
