Abstract

A recommendation information providing apparatus includes: a stay record managing section configured to store a stay record as a record when each of a plurality of users stayed in each of a plurality of locations; and a visit pattern calculating section configured to calculate a first visit pattern showing statistic data of the stay records for each of the plurality of locations. A candidate location extracting section extracts a second visit pattern to a specified location related to recommendation information from a plurality of the first visit patterns, extracts a third visit pattern which meets a determination value met by the second visit pattern from the plurality of first visit patterns, and extracts a similar location having the third visit pattern from the plurality of locations. A recommendation level calculating section extracts from the stay records, a first user and a second user of the plurality of users who stayed in at least one of the specified location and the similar location, calculates a fourth visit pattern of the first user to the specified location and the similar location from ones of the stay records related to the first user, calculates a fifth visit pattern of the second user to the specified location and the similar location from ones of the stay records related to the second user, and calculates a first priority level of the specified location and the similar location to be notified to the first user and a second priority level of the specified location and the similar location to be notified to the second user based on the fourth visit pattern and the fifth visit pattern.
