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

摘要

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.

主权项

1. An information distribution method comprising:
acquiring, by a computer, terminal location information of a plurality of mobile terminals, the terminal location information representing each location at which each of the plurality of mobile terminals receives distributed evaluation information of a facility; determining whether a user of one of the plurality of mobile terminals which have received the evaluation information has visited the facility in the evaluation information and calculating a visit distance between the facility which the user has visited and a location at which a mobile terminal of the user receives the evaluation information of the facility which the user has visited, using the terminal location information; and defining a distribution range of the evaluation information using a relationship between the visit distance calculated and a threshold number of visits to the facility by recipients of the distributed evaluation information.
