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.

First claim

The invention claimed is:

1. A moving means determination device comprising:
processing circuitry configured to
store, in a memory, a scoring table for determining a moving route of railroad of a user terminal held by a user using monitoring geofence determined based on a check-in point determined for determination;
acquire a history of position management information indicating that the user terminal is located in a geofence range based on a predetermined check-in point as a position management log; and
determine the moving route of railroad of the user terminal on the basis of the position management log and the scoring table stored in the memory,
wherein in the scoring table, a predetermined coefficient is assigned to each moving route with respect to the monitoring geofence, and
wherein the processing circuitry determines the moving route by adding up the coefficients corresponding to the position, when a position associated with the movement of the user is within the monitoring geofence.

2. The moving means determination device according to claim 1 , wherein the processing circuitry determines the moving route of railroad of the user terminal on the basis of the position management log including attribute information which is a correct answer value for identifying a moving route of railroad, and determines the moving route of railroad of the user terminal on the basis of the scoring table in a case where the determination is impossible.

3. The moving means determination device according to claim 1 , wherein the processing circuitry is further configured to:
acquire a check-in-point of position management information, satisfying predetermined conditions among position management logs of a plurality of user terminals acquired, as a monitoring check-in-point; and
calculate a coefficient for each moving route of railroad on the basis of the monitoring check-in-point,
store, in the memory, a database for determination, having a coefficient associated for each piece of the monitoring check-in-point and for each moving route of railroad, as the scoring table.

4. The moving means determining device according to claim 1 ,
wherein the predetermined coefficient for each moving route is a sum of an appearance frequency coefficient indicating a frequency of being located in the monitoring geofence and a stay time coefficient at that time.

5. A moving means determination device comprising
processing circuitry configured to:
store, in a memory, a learning model in which a moving route of railroad of a user terminal held by a user is constructed on the basis of information indicating a behavior of each user for each check-in point;
acquire a history of position management information indicating that the user terminal is located in a range based on a predetermined check-in-point as a position management log; and
determine the moving route of railroad in which the user terminal moves, on the basis of the position management log and the learning model stored in the memory,
wherein the learning model is learned by using information indicating a user's behavior and a moving time to a geofence adjacent to each geofence as an explanatory variable, and the moving route of the railway as a target variable, and
the information indicating the user's behavior is at least one of a frequency at which the user is located within a geofence based on a check-in point, a staying time at each geofence.

6. The moving means determination device according to claim 5 , wherein the processing circuitry is further configured to:
acquire position management information indicating that the user terminal is located in a range based on a predetermined check-in-point among position management logs of a plurality of user terminals acquired, the position management information satisfying predetermined conditions established for each moving route of railroad; and
generate a learning model for each moving route of railroad on the basis of information indicating a behavior of each user for each check-in-point in the position management information.

7. A method, implemented by processing circuitry of a moving means determination device, comprising:
storing, in a memory, a scoring table for determining a moving route of railroad of a user terminal held by a user using monitoring geofence determined based on a check-in point determined for determination;
acquiring a history of position management information indicating that the user terminal is located in a geofence range based on a predetermined check-in point as a position management log; and
determining the moving route of railroad of the user terminal on the basis of the position management log and the scoring table stored in the memory,
wherein in the scoring table, a predetermined coefficient is assigned to each moving route with respect to the monitoring geofence, and
wherein the processing circuitry determines the moving route by adding up the coefficients corresponding to the position, when a position associated with the movement of the user is within the monitoring geofence.
