First Claim
1. An information distribution system comprising:
- a location information acquisition unit that acquires terminal location information indicating the current location of a mobile terminal;
a location information storage unit that stores the terminal location information;
a location information update unit that updates terminal location information stored in the location information storage unit to terminal location information that has been acquired by the location information acquisition unit;
an evaluation information storage unit that stores evaluation information indicating an evaluation of a facility; and
distribution range information indicating a distribution range from the facility for distributing the evaluation information to the mobile terminal;
an evaluation information distribution unit that distributes the evaluation information to the mobile terminal if the current location of the mobile terminal indicated by the terminal location information is within the distribution range indicated by the distribution range information;
a distribution information storage unit that stores distribution time terminal location information indicating the location of the mobile terminal at a time when the evaluation information distribution unit distributed the evaluation information to the mobile terminal;
a visit determination unit that, based on the terminal location information or on setting information indicating a facility that a user of the mobile terminal has set as a navigation destination or stopover, determines whether the user of the mobile terminal to which the evaluation information has been distributed has visited the facility in the evaluation information, and upon determining that the user of the mobile terminal has visited the facility in the evaluation information, calculates a visit distance indicating the distance between the location of the mobile terminal indicated by the distribution time terminal location information and the location of the facility in the evaluation information;
a distribution range evaluation unit that determines whether the distribution range is effective based on the visit distance; and
a distribution range change unit that updates the distribution range information so that the distribution range is enlarged if the distribution range evaluation unit has determined that the distribution range is effective, and updates the distribution range information so that the distribution range is reduced if the distribution range evaluation unit has determined that the distribution range is not effective.

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.

7. An information distribution method comprising:
-
a location information acquisition step in which a location information acquisition unit included in a computer acquires terminal location information indicating the current location of a mobile terminal; a location information update step in which a location information update unit included in the computer, by referencing a location information storage unit that stores the terminal location information, updates terminal location information stored in the location information storage unit to terminal location information that has been acquired in the location information acquisition step; an evaluation information distribution step in which an evaluation information distribution unit included in the computer, by referencing an evaluation information storage unit that stores evaluation information indicating an evaluation of a facility and stores distribution range information indicating a distribution range from the facility for distributing the evaluation information to the mobile terminal, distributes the evaluation information to the mobile terminal if the current location of the mobile terminal indicated by the terminal location information is within the distribution range indicated by the distribution range information; a visit determination step in which a visit determination unit included in the computer, by referencing a distribution information storage unit that stores distribution time terminal location information indicating the location of the mobile terminal at a time when the evaluation information was distributed to the mobile terminal in the evaluation information distribution step, and based on the terminal location information or on setting information indicating a facility that a user of the mobile terminal has set as a navigation destination or stopover, determines whether the user of the mobile terminal to which the evaluation information has been distributed has visited the facility in the evaluation information, and upon determining that the user of the mobile terminal has visited the facility in the evaluation information, calculates a visit distance indicating the distance between the location of the mobile terminal indicated by the distribution time terminal location information and the location of the facility in the evaluation information; a distribution range evaluation step in which a distribution range evaluation unit included in the computer determines whether the distribution range is effective based on the visit distance; and a distribution range change step in which a distribution range change unit included in the computer updates the distribution range information so that the distribution range is enlarged if the distribution range has been determined to be effective in the distribution range evaluation step, and updates the distribution range information so that the distribution range is reduced if the distribution range has been determined to not be effective in the distribution range evaluation step.
