According to points 31 and 32 shown in FIG. 8, it can be understood that the owner of the terminal device 100 stays in the destination area for about 3000 seconds after arriving at the destination area. Further, according to points 32 and 33 shown in FIG. 8, it can be seen that the vehicle has moved to a place 6 km away from the target area in about 3000 seconds.

  FIG. 9 is a diagram illustrating a third specific example of the generated graph image. FIG. 9 shows a graph image when the owner of the terminal device 100 is a resident who lives near the destination area. The vertical and horizontal axes are the same as in FIG. According to the points shown in FIG. 9, it can be seen that the user stays for a long time within about 2,000 meters from the store and cannot leave the store. From such behavior, it can be seen that they are neighbors. In addition, when determining whether or not the owner of the terminal device 100 has visited the destination area, the determination unit 209 can determine without excluding the terminal device 100 that has transmitted such behavior information.

  FIG. 10 is a diagram illustrating a fourth specific example of the generated graph image. FIG. 10 shows a graph image when the owner of the terminal device 100 has passed the store side. The vertical and horizontal axes are the same as in FIG. According to points 40 and 41 shown in FIG. 10, it can be seen that the owner of the terminal device 100 has moved from a position about 19 km away from the destination area to the destination area in about 1800 seconds. Further, according to points 41 and 42 shown in FIG. 10, it can be understood that the owner of the terminal device 100 stays in the destination area for about 600 seconds after arriving at the destination area. Further, according to points 42 and 43 shown in FIG. 10, it can be seen that the vehicle has moved to a place 17 km away from the target area in about 1800 seconds. Since the stay time in the store is as short as 600 seconds, it can be seen that the owner of the terminal device 100 did not visit the store but only passed through the road on the store side. In addition, when determining whether or not the owner of the terminal device 100 has visited the destination area, the determination unit 209 can determine without excluding the terminal device 100 that has transmitted such behavior information.

  FIG. 11 is a flowchart illustrating a flow of a process of determining whether the owner of the terminal device 100 according to the embodiment has visited the destination area. The determination unit 209 acquires the determination information (Step S101). The determination information may be obtained based on an instruction received from the input unit 202, or may be obtained based on an instruction received from outside the determination device 200 via the communication unit 201. The determination unit 209 determines an advertisement identifier that specifies the terminal device 100 to be determined (Step S102).

  The determination unit 209 acquires the first behavior information (Step S103). Specifically, the determination unit 209 specifies the behavior information having the determined advertisement identifier value. The determination unit 209 acquires, as the first behavior information, the behavior information in which the value of the position information included in the specified behavior information is inside the target area. The target region represents the inside of a circle having a radius value as a radius with the value of the target position included in the determination information as the center.

  The determination unit 209 acquires the second behavior information (Step S104). Specifically, the determination unit 209 determines the advertisement identifier included in the first action information among the plurality of pieces of action information including time information indicating a time earlier than the value of the time information included in the first action information. As the second action information, action information including an advertisement identifier having the same value as the above and including position information closest to the target area is acquired.

  The determination unit 209 acquires the third action information (Step S105). Specifically, the determination unit 209 is the same as the identification information included in the first action information among the plurality of pieces of action information including time information indicating a time later than the time information included in the first action information. The third behavior information including the value advertisement identifier and including the position information closest to the target area is acquired.

  The determination unit 209 calculates the stay time based on the time information included in the acquired second behavior information and third behavior information (Step S106). Specifically, the determination unit 209 calculates a difference value between the time information included in the third action information and the time information included in the second action information as the stay time of the target area. The determination unit 209 determines whether the calculated stay time is included in the range of the stay threshold of the determination information (Step S107). When the calculated stay time is included in the range of the stay threshold of the determination information (step S107: YES), the determination unit 209 determines that the owner of the terminal device 100 has visited the destination area (step S108). When the calculated stay time is not included in the stay threshold range of the determination information (step S107: NO), the determination unit 209 determines that the owner of the terminal device 100 has not visited the destination area (step S107). S109).

  The determination unit 209 generates determination result information based on the determination result (Step S110). The determination unit 209 records the generated determination result information in the determination result storage unit 206 (Step S111).

  In the thus configured determination system 1, the determination unit 209 of the determination device 200 determines that the owner of the terminal device 100 is in the destination area based on the position information included in the plurality of pieces of behavior information acquired from the terminal device 100. It is determined whether or not a visit has been made. With this configuration, the position of the terminal owner can be determined with higher accuracy.

  In the above-described embodiment, the stay threshold included in the determination information is described as an example in which the lower limit is 1000 and the upper limit is 3000. However, the stay threshold is not limited to these values. Further, the determination information may hold a plurality of stay thresholds.

  In the above-described embodiment, the target area is described as representing the inside of a circle having a radius value as a radius with the value of the target position included in the determination information as the center, but the target area is not limited to the circle. For example, the destination area may be represented as being inside a polygon formed by connecting a plurality of positions indicated by latitude and longitude by line segments. In this case, the determination information holds a plurality of pieces of latitude and longitude information.

  The determination unit 209 may be configured to determine whether or not the owner of the terminal device 100 has visited the destination area based on the shape of the graph image generated by the graph generation unit 210. In this case, the determination unit 209 may store a plurality of graph images serving as models in advance. The determination unit 209 compares the generated graph image with a model graph image to calculate a similarity. A known technique may be used for calculating the similarity. The determination unit 209 determines that the owner of the terminal device 100 has visited the destination area when the similarity is equal to or greater than the predetermined threshold. When the similarity is less than the predetermined threshold, the determination unit 209 determines that the owner of the terminal device 100 has not visited the destination area. For example, the determining unit 209 may be configured to determine that the graph image has come to the destination area when the graph image has a shape like the pan shown in FIG. 7 or 8, for example. For example, when the graph image has a shape like a straight line shown in FIG. 9 or a shape like a V-shape shown in FIG. 10, the determination unit 209 determines that the target image has not been visited. May be configured.

  The determination unit 209 may be configured to estimate the means of transportation of the owner of the terminal device 100. The determination unit 209 calculates the speed based on, for example, two pieces of behavior information. When the calculated speed is higher than a predetermined threshold, the determination unit 209 estimates that the owner of the terminal device 100 has visited the destination area with the vehicle. If the calculated speed is equal to or less than the predetermined threshold, the determination unit 209 estimates that the owner of the terminal device 100 has visited the destination area on foot. The determination unit 209 may include the estimation result in the determination result information. The action information used to calculate the speed is, for example, an action information including time information having a time of visiting the target area and an action information including time information having a time earlier than the time of visiting the target area. Information, and may be, behavior information including time information having a time immediately before leaving the target area, and behavior information including time information having a time later than the time immediately before leaving the target area, There may be.

  The determining unit 209 may be configured to acquire, as the fourth behavior information, behavior information including time information indicating the latest time from the acquired first behavior information. In this case, the determination unit 209 calculates the difference between the value of the time information included in the first action information and the value of the time information included in the fourth action information as the stay time of the target area.

  The determination unit 209 may be configured to acquire, from the advertisement distribution device 300, the advertisement identifier of the terminal device 100 to which the advertisement information has been distributed. With this configuration, the determination unit 209 may also determine whether the owner of the terminal device 100 determined to have visited the destination area is a person who has received the advertisement information. With this configuration, the distributor of the advertisement information can check the effect of the advertisement information. Note that the result of the determination as to whether or not the advertisement information has been received may be included in the determination result information.

  The position information acquisition unit 106 may acquire the position information by a method other than the satellite positioning system. For example, the position information acquisition unit 106 may be configured to acquire position information from a short-range wireless communication device such as a wireless LAN access point or a beacon oscillator. Further, the position information acquiring unit 106 may be configured to acquire the position information at the timing of receiving the radio wave from the short-range wireless communication device when acquiring the position information from the satellite positioning system.

  In the present embodiment, the determination device 200 and the advertisement distribution device 300 are described as one device, but may be configured by a plurality of devices. The determination device 200 and the advertisement distribution device 300 may be configured by a cloud computing system.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments and includes a design and the like within a range not departing from the gist of the present invention.

  The present invention is applicable to a store-type business in which the owner of the terminal device 100 visits a target area such as a store.
