  • Patent number: 11895559
    Abstract: An object is to provide a moving route determination device that makes it possible to accurately determine a user's moving route. A server device 100 includes a geofence evaluation unit 105 configured to store a scoring table for determining a moving route of a user terminal 200, a check-in log acquisition unit 103 configured to acquire at least one of a check-in log which is a history of position management information, such as check-in information, settlement information, or search information, indicating that the user terminal 200 is located in a predetermined range, a settlement log, and a search log as a position management log, and a scoring determination unit 106 configured to determine a moving route of the user terminal 200 on the basis of the position management log and determination information stored in the geofence evaluation unit 105 in a case where a moving means is not able to be determined from at least one of the check-in log, the settlement log, and the search log.
