A recommender system , or a recommendation system sometimes replacing 'system' with a synonym such as platform or engine , is a subclass of information filtering system that seeks to predict the "rating" or "preference" a user would give to an item.

Он распорядился установить жучок в личном компьютере Стратмора - чтобы контролировать его электронную почту, его внутриведомственную переписку, а также мозговые штурмы, которые тот время от времени предпринимал. Если Стратмор окажется на грани срыва, директор заметит первые симптомы.

Панк изумленно взглянул на бутылку, потом отпил изрядный глоток и тупо уставился на Беккера. - Чего вы от меня хотите, мистер. Беккер улыбнулся: - Я ищу одну девушку.
