It has a reminder unit 57.

The determination unit 51 is provided on the server 4 or the client (portable information device S), and determines whether or not the condition (second condition) including the state of the user being in the operating state is satisfied in response to the trigger of the client. judge. The condition (second condition) may include that a predetermined time has elapsed from the time when the user's previous position information was acquired by the position information acquisition unit 52.
The position information acquisition unit 52 acquires the user's position information measured by the position information measuring device of the user's first information device when the determination unit 51 determines that the user satisfies the condition (second condition). To do.
The position information storage unit 53 associates the position information acquired by the position information acquisition unit 52 with the presence classification of the user's operating state at the time of acquisition of the position information acquired by the position information acquisition unit 52, and positions the positions. It is stored in the information storage database 41. More specifically, the position information storage unit 53 has the position information acquired by the position information acquisition unit 52, the acquisition time at the time of acquisition of the position information acquired by the position information acquisition unit 52, and the position for each user ID. The presence classification of the user's operating state at the time of acquisition of the position information acquired by the information acquisition unit 52 is stored in association with each other.

The estimation processing unit 54 estimates a plurality of candidate work locations of the user based on the position information associated with the operating state of the user stored in the position information storage database 41. The estimation processing unit 54 may perform cluster analysis using the location information stored in the location information storage database 41 as a node, and estimate at least one candidate work location based on the result of this cluster analysis.
The work location registration unit 55 considers the candidate work location that satisfies the first condition including having a predetermined number or more of the location information among the candidate work locations estimated by the estimation processing unit 54 as the work location, and the deemed work location. The place and the location information of the deemed work place are associated and registered in the work place database 31.

May be the coordinates of the center of gravity of the nodes included in the candidate work location including the largest number of nodes.
When the work status determination unit 56 confirms the work status, the location information of the user whose work status is to be confirmed is the work location registered in the work location database 31, and the work status in the attendance management system. When the presence classification of the user to be confirmed is in the operating state, it is determined that the user to be confirmed of the working status is working.
The change prompting unit 57 causes the client to display a message prompting the client to change the operating state when the user is in the operating state and the user comes out of a predetermined range of the work location.
Next, the operation of the work location estimation device according to the embodiment will be described with reference to the flowchart.

First, a method of acquiring data such as position information from GPS mounted on the user's portable information device S and storing the acquired data such as position information in a server will be described.

FIG. 5 is a flowchart for explaining a method of storing position information in response to a trigger from the user's portable information device S.

The application of the portable information device S determines whether or not the trigger of the portable information device S has occurred (S1). For example, when the application of the portable information device S communicates with the server 4, a certain time (for example, every hour) elapses when the application of the portable information device S is started for the first time. For example.

When it is determined in S1 that the trigger of the portable information device S has occurred (Yes in S1), the condition determination is performed by the application of the portable information device S (S2: determination unit 51).

Specifically, the determination by the determination unit 51 is as follows. A certain amount of time (for example, 30 minutes) has passed since the acquisition time of the previously stored data. The presence classification of the attendance management system of the linked groupware is in operation, etc.

The application of the portable information device S accesses the attendance management system of the server 4 as needed, and acquires the data necessary for determining the conditions.

If it is determined in S2 that the conditions are not satisfied, the process ends (No in S2). When it is determined in S2 that the condition is satisfied (Yes in S2), the data acquisition process is performed by the application of the portable information device S (S3: position information acquisition unit 52).

In this data acquisition process, in addition to the position information measured by the position information measuring device (GPS) of the user's portable information device S, Wi-Fi, etc., the user ID, the acquisition time at the time of acquiring the position information, and the position information acquisition The presence classification of the user's operating state at the time of acquisition of the position information acquired by the unit 52 is included. The data (user ID, location information, acquisition time, and presence classification of the operating state) acquired by the portable information device S is transmitted to the server 4.

The work location estimation program 22 of the server 4 stores the data (user ID, location information, acquisition time, and presence classification of the operating state) transmitted from the portable information device S in the location information storage database 41 in association with each other. (S4: Position information storage unit 53) ends the process.

FIG. 6 is a flowchart for explaining a method of storing position information in response to a trigger from the user's computer C.

The work location estimation program 22 of the server 4 determines whether or not the trigger of the computer C has occurred (S11). The trigger of the computer C is, for example, when the operation is performed by the browser of the computer C, or when a certain time (for example, every hour) elapses.

When it is determined in S11 that the trigger of the computer C has occurred (Yes in S11), the condition determination is performed by the work location estimation program 22 of the server 4 (S12: determination unit 51).

Specifically, the determination by the determination unit 51 is as follows. A certain amount of time (for example, 30 minutes) has passed since the acquisition time of the previously stored data. The presence classification of the attendance management system of the linked groupware is in the operating state.

If it is determined in S12 that the conditions are not satisfied, the process ends (No in S12). When it is determined in S12 that the condition is satisfied (Yes in S12), a push notification is transmitted to the portable information device S by the work location estimation program 22 of the server 4 (S13). This push notification is a command for acquiring location information to the application of the portable information device S.

When the application of the portable information device S receives this push notification from the server 4, it performs a data acquisition process (S14: location information acquisition unit 52).

In this data acquisition process, in addition to the position information measured by the position information measuring device (GPS) or WiFi of the user's portable information device S, the user ID, the acquisition time at the time of acquiring the position information, and the position information acquisition unit 52 Includes the presence classification of the user's operating status at the time of acquisition of the location information acquired by. The data (user ID, location information, acquisition time, and presence classification of the operating state) acquired by the portable information device S is transmitted to the server 4.

The work location estimation program 22 of the server 4 stores the data (user ID, location information, acquisition time, and presence classification of the operating state) transmitted from the portable information device S in the location information storage database 41 in association with each other. (S15: Position information storage unit 53) ends the process.

In the server 4, the stored data (user ID, location information, acquisition time, and presence classification of operating status) are stored up to a predetermined number (for example, 50 cases), and the data exceeding the predetermined number is old. You may delete it from.

Next, the work location estimation process will be described. FIG. 7 is a flowchart for explaining the work location estimation process. This work location estimation process is performed for each user ID stored in the location information storage database 41. That is, the work location is estimated for each user ID.

As shown in FIG. 7, first, the work location estimation program 22 of the server 4 determines whether or not the condition that is a prerequisite for the estimation process is satisfied (S21). This condition is a condition for preventing bias in work location estimation due to a small number of location information, and the number of location information of the same user ID stored in the location information storage database 41 is a certain number or more (for example). It is a condition that the number is 10 or more).

If it is determined in S21 that the conditions are not satisfied, the process ends. On the other hand, if it is determined in S21 that the condition is satisfied, the work location estimation program 22 of the server 4 performs estimation processing (S22: estimation processing unit 54).

This estimation process is performed as follows.

The work location estimation program 22 of the server 4 estimates a plurality of candidate work locations of the user based on the same user ID stored in the location information storage database 41 and the location information associated with the operating state of the user. To do.

Specifically, the estimation processing unit 54 performs cluster analysis using the location information stored in the location information storage database 41 as a node, and estimates at least one candidate work location based on the result of this cluster analysis.

The cluster analysis is performed because the position information stored in the position information storage database 41 cannot be simply decided by majority due to the influence of accuracy problems and errors. FIG. 8 is a diagram showing an example of location information (nodes) analyzed by cluster analysis and grouped.

FIG. 8 shows an example in which position information (nodes) is classified into four groups (candidate work locations) G1 to G4, and groups G2 and G4 have a predetermined number or more of position information.

This cluster analysis is a non-hierarchical cluster analysis using the Newman algorithm, and the accumulated position information is used as a node and the distance is used as an edge weight. It should be noted that edges may not be stretched between nodes separated by a certain distance or more. The Newsman algorithm is disclosed, for example, in the reference "Clustering of social graph by the Newsman algorithm" (https://www.slideshare.net/komiyaatushi/newman-6670300).

Next, does the work location estimation program 22 of the server 4 satisfy the condition (first condition) including having a predetermined number or more of the location information among the plurality of candidate work locations estimated in S22? Judge whether or not (S23: Work location registration department 55).

If it is determined in S23 that there is no candidate work location that satisfies the condition (first condition) including having a predetermined number or more of location information, the process ends. On the other hand, when it is determined that there is a candidate work location that satisfies the condition (first condition) including having a predetermined number or more of location information, the work location estimation program 22 of the server 4 works at the candidate work location that satisfies the condition. It is regarded as a place, and the deemed work place is associated with the location information of the deemed work place and registered in the work place database 31 (S24: work place registration unit 55).

The location information of the work location registered by the work location registration unit 55 is the candidate work location including the most nodes among the plurality of candidate work locations, and is the coordinates of the center of gravity of the nodes included in the candidate work locations. There may be.

Next, the process of determining the work status using the work location estimated in this way will be described.

When the work status determination request is received from the user or the attendance management management program 24, the work location estimation program 22 of the server 4 registers the location information of the user whose work status is to be confirmed in the work location database 31. When the presence classification of the user who is the location and the attendance management system is to check the work status is in the operating state, it is determined that the user is working (work status determination unit 56).

Next, the process of urging the user to change the occupancy classification by using the estimated work location will be described.

The work location estimation program 22 of the server 4 puts a geo-fence on the work location including the estimated work location. Here, the "geofence" is a function of detecting entry and exit from a designated point in a certain range as an area.

Then, when the user exits the geo-fence, if the presence classification is in the operating state, the user's portable information device S is displayed with a message prompting the user to change the operating state (change prompting unit 57). ..

FIG. 9 is a diagram showing an example of a message displayed on the screen of the user's portable information device S. As shown in FIG. 9, on the screen D of the portable information device S, the message M "Did you forget to change the presence classification? It seems that you have left the office, but do not forget to change the presence classification. "Hmm?" Is displayed.

As a result, the work location estimation system and the attendance management system can be linked.
<Modification example>
1. 1. In the above-mentioned estimation process, the estimation process is performed for each user ID, but a department ID associated with the user ID may be prepared and the estimation process may be performed using this department ID.
2. In the above-mentioned estimation process, the estimation process is performed for each user ID, but the estimation process may be performed for each presence classification of the same user ID.

Therefore, according to the work location estimation system of the embodiment, it is possible to estimate and register a place such as a work place without input from the user, so that it is possible to save the trouble of registering the work place.

In addition, according to the work location estimation system of the embodiment, the enrollment classification in the operating state of the user is used in cooperation with the attendance management system provided as groupware, so that the existing attendance management system is effectively utilized. be able to.

Further, according to the work location estimation system of the embodiment, a geo-fence is set up for the estimated work location, and when the user crosses the geo-fence, a message prompting the user to change the presence classification is sent. Therefore, the quality of management of the attendance management system that cooperates synergistically can be improved.
