Information distribution system, information distribution method, and information distribution program

Abstract

An information distribution system includes a visit determination unit (42), a distribution range evaluation unit (43), and a distribution range change unit (44). The visit determination unit (42) determines whether a user of a mobile terminal (2) to which evaluation information has been distributed has visited a facility in the evaluation information, and upon determining affirmatively, calculates a visit distance indicating the distance between the location of the mobile terminal indicated by distribution time terminal location information and the location of the facility in the evaluation information. The distribution range evaluation unit (43) determines whether the distribution range is effective based on the visit distance. The distribution range change unit (44) updates distribution range information so that the distribution range is enlarged if the distribution range is effective, and updates the distribution range information so that the distribution range is reduced if the distribution range is not effective.
