Apparatus, method, and computer-readable recording medium for providing information based on information elements identified by using user history information and estimated viewing duration information

Abstract

An information processing device identifies a search query of a target user to whom an electronic coupon is to be issued and the corresponding search time, and adds the elapsed time between the search time and the current time to an expected interval between the current time and viewing by the target user, to calculate an expected viewing duration. The information processing device then identifies, as estimated viewed items, items associated with an estimated viewing duration of less than or equal to or of less than the calculated expected viewing duration, among items included in estimated viewing duration information corresponding to the identified search query. Based on items included in the target user's history information and on the identified estimated viewed items, the information processing device generates an electronic coupon to be provided to the target user.
