摘要

A method is provided for recommending one or more items among a plurality of items to a first user of a recommendation system. The method comprises generating a weighted data set by applying a weight factor to each of a plurality of user event data sets each derived from a previous user event of a second user of the recommendation system. Each of said user event data sets comprises a user identifier of the second user, an item identifier of an item involved in the previous user event, and time information on the time of the previous user event. The weight factor is derived from the time information of the corresponding previous user event. The method further comprises determining the one or more recommended items based on an algorithm using the weighted data set.
