摘要： A recommender system stores rating values for items associated with identified users and groups of users and information representing users that are part of the groups of users. A correlation module computes correlations between a first group and other groups, by retrieving the information representing users in the first group and the other groups from the group composition storage system, retrieving the information representing rating values for items from a reference set associated with the users of the first group and the other groups and computing an aggregate of correlations between the rating values for items from the reference set associated with pairs of users, each pair comprising a respective one of the users of the first group and a respective one of the users form one of the other groups. A composition module configured to compute an aggregate of parameter values for the group from parameter values, such as rating values for items, associated with the other groups, wherein the other groups that are used to compute the aggregate of parameter values are selected and/or weighted dependent on the aggregate of correlations. By aggregated correlations as a group based similarity score, the adaptability of the recommender system to group composition is increased.

摘要： A recommender system provides recommendation scores based on stored ratings for media items, for example to assist control of selection of a media item for rendering by a terminal. Data representing stored rating values for media items is stored in a storage system for use to compute the recommendation scores. A processing system record an input rating value for a first one of the media items in the storage system, based on measured activity or input of a user. Furthermore information is acquired about a group of users in the company of which the input rating value applies for the user. This information is recorded in combination with the rating value. The processing system may compute a recommendation score for a second group of users from the stored rating values, dependent on a comparison of the second group of users and the recorded information about the group for which it applies.
