1. A method performed by an information processing apparatus for recommending one or more items among a plurality of items to a first user of a recommendation system, the method comprising:

  • deriving, using circuitry of the information processing apparatus, a first weight factor for a plurality of user event data sets from an order of previous user events of a second user;

    generating, using the circuitry, a weighted data set by applying the first weight factor to each of the plurality of user event data sets each derived from a previous user event of the second user of the recommendation system, whereineach of the user event data sets includes a user identifier of the second user, an item identifier of an item involved in the previous user event of the second user, and time information regarding a time of the previous user event of the second user, andthe first weight factor is derived from the time information of the previous user event of the second user; and

    determining, using the circuitry, the one or more recommended items based on an algorithm using the weighted data set,wherein the order of previous user events of the second user is ordered according to most recent user event of the second user to least recent user event of the second user, respective weights for the ordered previous user events of the second user descending from highest weight for the most recent user event to lowest weight for the least recent user event.
