FIELD: physics, computer engineering.SUBSTANCE: invention relates to controlling a recommender system and specifically to controlled placement of auxiliary media data relative to content items presented to a user. The method includes scheduling a content item in a first scheduler (111) based on a user profile obtained from a recommender system, receiving information about scheduled content and deciding in a second scheduler (118) based on the received information which auxiliary media data to place into a presentation space. Priority is allocated to items of auxiliary media data based on one of: targeting information, prioritisation information, factoring information and popularity information. The popularity information is determined based on a user rating or by measuring a dropping or watching rate of an item of said auxiliary media data. Furthermore, placement of auxiliary media data is controlled relative to content items presented to a user.EFFECT: high efficiency of using system resources by selecting auxiliary media data depending on user preferences and type of selected content item.15 cl, 7 dwg |
