Moreover, the same code | symbol is attached | subjected to the same site | part in the following each embodiment, and the overlapping description is abbreviate | omitted.

[1. Example of determination processing]
First, an example of the determination process according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of a determination process according to the embodiment. In FIG. 1, an example of determination processing executed by the determination apparatus 100 which is an example of a computer that operates according to the determination program according to the embodiment will be described. Specifically, in FIG. 1, the determination apparatus 100 acquires position information indicating the position of the user and information on the abstraction level of the position, and based on a plurality of determination criteria corresponding to the acquired information on the abstraction level. An example of performing processing for determining whether or not to abstract position information will be described.

  The determination device 100 illustrated in FIG. 1 is a server device that acquires position information transmitted from the user terminal 10 and stores the acquired position information in a storage unit. For example, the determination apparatus 100 acquires identification information for identifying each user in association with information indicating the position of each user, and accumulates the acquired information as position information. For example, the determination apparatus 100 is a server that provides a predetermined service via an application installed in a terminal device used by the user, and periodically acquires position information from the user as the application is used. Moreover, the determination apparatus 100 provides various services using the position information. In the embodiment, the determination apparatus 100 provides, for example, a service related to a navigation application that provides traffic guidance using position information of the user, a service related to a portal application that provides various information to the logged-in user, and the like. And Note that the determination apparatus 100 may provide the acquired location information and the like to other providers who provide various services.

  A user terminal 10 illustrated in FIG. 1 is an information processing terminal such as a smartphone. In the embodiment, the user terminal 10 is used by a user U01 that is an example of a user. Below, the user terminal 10 may be read as a user. For example, "the user U01 transmits position information" may actually mean "the user terminal 10 used by the user U01 transmits position information".

  The user terminal 10 detects the position where the own device is located (for example, the numerical value of the longitude and the latitude, etc.) using positioning means for positioning the position such as GPS (Global Positioning System), for example, and information indicating the detected position Get the location information that is. The position information may include not only the information indicating the position but also the time when the position is detected. Then, the user terminal 10 transmits the detected position information to the determination device 100, for example, according to control of the application to be used. Specifically, the user terminal 10 periodically and continuously transmits the position information to the determination apparatus 100 according to the control (function) of the navigation application or the portal application which is an application managed by the determination apparatus 100. The position information transmitted from the user terminal 10 is accumulated in a storage unit of the determination apparatus 100 and used for various information processing.

  As described above, the user terminal 10 acquires the detected position, and transmits position information corresponding to the acquired position to the determination apparatus 100. However, since transmission of the acquired position information to the determination apparatus 100 is periodically and continuously performed from all the user terminals 10 using the service, the position information acquired by the determination apparatus 100 has a huge amount of information. . For this reason, it is desirable that the determination apparatus 100 not store the position information randomly in the storage unit but store only the position information useful for providing the service. In other words, the determination apparatus 100 desirably abstracts and holds the position information. In the embodiment, the abstraction of position information refers to, for example, when a plurality of position information indicates a position where a specific user is located, a predetermined number is calculated from the plurality of position information so as not to affect information processing. Excludes (thinning out) processing. In addition, abstraction of position information means that even if there are multiple different pieces of position information that do not greatly affect information processing, the plural pieces of position information are rounded (considered as information indicating the same position). Therefore, it can be said that the entire amount of information is compressed.

  Therefore, the determination apparatus 100 according to the embodiment acquires information on the degree of abstraction of the position in the position information indicating the position of the user, as well as the position information. Then, the determination apparatus 100 determines whether to abstract the position information based on a plurality of determination criteria corresponding to the information on the degree of abstraction. More specifically, the determination apparatus 100 determines whether or not to store the acquired position information in the storage unit as a plurality of determination criteria corresponding to the information on the abstraction level as the abstraction of the position information. Based on the determination criterion, it is determined whether or not the position information is stored in the storage unit. By such control, the determination apparatus 100 can extract and store only useful position information, and therefore can prevent the storage capacity from being exhausted due to the accumulation of position information. In other words, the determination apparatus 100 can efficiently acquire position information. In addition, with respect to the information on the degree of abstraction of the position, how much the position information is held in the storage unit (that is, the determination apparatus 100 does not hold all the acquired position information but all acquired position information From among the above, it is information that serves as a guideline indicating how to extract position information that is assumed to have no problem in information processing even if it is discarded (position information that does not have a problem even when abstracted). In the embodiment, the information on the degree of abstraction of the position is, for example, information on positioning when the user terminal 10 measures the position of the user. For example, the information related to the positioning of the position is information used to indicate the accuracy of specifying the position of the user in the information indicating the position of the user. For example, the accuracy of specifying the position of the user varies depending on the positioning means for measuring the position, the information processing capability of the terminal device for acquiring the position information, and the like. That is, information on positioning means, for example, positioning means used when the user terminal 10 measures the position, information indicating the range of error of the measured position, and information processing of the user terminal 10 for acquiring the position information Such as ability. Hereinafter, the flow of the determination process according to the embodiment will be described with reference to FIG.

  In the example of FIG. 1, the user terminal 10 detects position information in accordance with the function of a predetermined application installed by the user U01, and transmits position information corresponding to the detected position to the determination apparatus 100. For example, the user terminal 10 transmits the position information to the determination apparatus 100 while detecting the position of the own device using a predetermined positioning unit every 10 minutes.

  Here, the determination apparatus 100 according to the embodiment determines whether the position information transmitted from the user terminal 10 is stored in the storage unit according to the accuracy of the position detected (positioned) by the user terminal 10. Use the same criteria.

  For example, the accuracy of the position varies depending on the positioning means used when the user terminal 10 detects the position. In the example of FIG. 1, the user terminal 10 can use positioning means by GPS satellites (hereinafter simply referred to as “GPS”). In addition, the user terminal 10 determines the position of its own device by measuring the distance to a base station or an access point possessed by each communication company via the Wi-Fi (registered trademark) communication function (hereinafter simply referred to as “ May be used as “Wi-Fi”. Further, the user terminal 10 uses a Bluetooth (registered trademark) function of the user terminal 10 to connect to a beacon transmitter or the like, thereby positioning means (hereinafter simply referred to as “Bluetooth”) that identifies the position of the user terminal 10. Or “beacon” can be used.

  The determination apparatus 100 has different determination criteria for each positioning means as described above. Then, the determination apparatus 100 determines whether or not to abstract the position information acquired from the user terminal 10 using different determination criteria according to the positioning means when the position information is acquired by the user terminal 10 . For example, the determination apparatus 100 determines which of the position information acquired from the user terminal 10 is to be thinned out or which position information is left using the determination criterion. More specifically, the determination apparatus 100 determines whether or not to store the position information acquired from the user terminal 10 in the storage unit, using the determination criterion.

  In the embodiment, it is assumed that the accuracy when the position is measured by Wi-Fi is higher than the accuracy when the position is measured by GPS. Further, it is assumed that the accuracy when the position is measured by beacon is higher than the accuracy when the position is measured by Wi-Fi. In the embodiment, when the position information is acquired using a plurality of positioning means, the determination apparatus 100 uses a determination criterion corresponding to a positioning means with higher accuracy.

  For example, in FIG. 1, the user terminal 10 acquires position information using the GPS as a positioning unit until the user U01 leaves home and walks to the station. Then, the user terminal 10 transmits the acquired position information to the determination device 100 every predetermined time.

  In this case, the determination apparatus 100 performs the determination using the determination reference A01 that is the determination reference corresponding to the GPS among the acquired position information. For example, in the judgment criteria A01, "(Does the target (user U01 in the example in FIG. 1) move 500 meters or more?" Or "(1 hour or more has passed from the position detected most recently)?" The condition for storing the position information is included.

  Such a determination criterion is provided to harmonize the accuracy of the position stored in the storage unit with the amount of information. For example, since the position information acquired by the GPS is low in accuracy (that is, the error in specifying the position where the user U01 is located is large), even if the transition of the position information of the user U01 is acquired, the positions of all of them. Information is unlikely to be useful. In other words, as the positional information acquired by the GPS, a relatively rough movement information of the user U01 until the user U01 leaves his home and arrives at a specific base (station in the example of FIG. 1) (for example, several It can be said that it is sufficient to show position information indicating movement every 100 meters).

  For this reason, the determination apparatus 100 determines whether or not to store the position information, using the determination reference A01 provided with a relatively rough reference, for the position information detected using the GPS. In the example of FIG. 1, the determination apparatus 100 includes position information B01, position information B02, and position information that are position information that satisfies the determination criterion A01 among the position information acquired until the user U01 reaches the station from home. Information B03 is extracted as information to be held. Then, the determination apparatus 100 stores the extracted position information in the storage unit. On the other hand, determination apparatus 100 discards, without storing, the position information that does not satisfy determination reference A01 among the position information acquired while user U01 reaches from the home to the station.

  Subsequently, it is assumed that the user terminal 10 acquires position information using Wi-Fi as a positioning unit from when the user U01 arrives at a station until the user terminal 10 heads for a specific store in the station. For example, when an environment in which the user terminal 10 can use Wi-Fi is prepared in the station premises, the user terminal 10 can acquire position information using Wi-Fi as a positioning unit. In addition, the user terminal 10 may use detection of the position using GPS with Wi-Fi, if possible. Then, the user terminal 10 transmits the acquired position information to the determination device 100 every predetermined time.

  In this case, the determination apparatus 100 performs the determination using the determination reference A02 that is the determination reference corresponding to Wi-Fi among the acquired position information. For example, criteria such as “Is (target moved) 100 meters or more moved?” Or “Do you move other than straight line (from the most recently detected position)?” Is set in the judgment reference A02.

  For example, since the positional information acquired by Wi-Fi has high accuracy compared with the positional information acquired only by GPS, it may be useful to acquire the transition of the position of the user U01 within a certain range Is expensive. In addition, in a station yard or the like where Wi-Fi can be used, a manager may utilize position information, such as acquiring position information of each user and analyzing user behavior. That is, when it is possible to obtain position information by Wi-Fi, it may be required to obtain detailed position information in relation to the user's action as compared to GPS, so the condition is detailed in comparison with determination criterion A01. The provided criterion A02 is adopted. In addition, determination of whether a user's movement is a straight line represents, for example, between two points of the latest position and between two points of the position acquired next respectively as vectors, and both vectors are formed. It can be determined by whether or not the angle exceeds a predetermined threshold.

  In the example of FIG. 1, the determination apparatus 100 includes position information B04, position information B05, and position information that are position information that satisfies the determination criterion A02 among the position information acquired before the user U01 reaches the store from the station. Information B06 is extracted and stored. Then, the determination apparatus 100 discards, without storing, the position information that does not satisfy the determination reference A02 among the position information acquired during the time when the user U01 reaches the store from the station.

  Subsequently, the user terminal 10 acquires positional information using the beacon as a positioning unit until the user U01 enters the store and goes to the office. For example, when a beacon for analyzing the behavior of a visitor is placed on each display shelf of a store, the user terminal 10 can acquire position information using the beacon as a positioning means. In addition, the user terminal 10 may use detection of the position using Wi-Fi or GPS together with the beacon, if possible. Then, the user terminal 10 transmits the acquired position information to the determination device 100 every predetermined time.

  In this case, the determination apparatus 100 performs the determination using the determination reference A03 which is the determination reference corresponding to the beacon among the acquired position information. For example, criteria such as “Is (target moved) 1 meter or more?” Or “(has moved to another display shelf (from the most recently detected position))?

  For example, since the position information acquired by the beacon is higher in accuracy than the position information acquired by Wi-Fi or GPS, the user U01 looks at what kind of display shelf (article) the user U01 looks at, etc. It is possible to analyze the transition of the detailed position. That is, when position information is acquired based on beacon, it is necessary to hold more detailed position information regarding the user's action compared to Wi-Fi and GPS, so the condition is lower than the determination reference A02. The determination criterion A03 provided in more detail is adopted. Note that whether or not the user has moved to another display shelf is, for example, that communication with the user terminal 10 has been switched from a beacon installed on the display shelf to another beacon installed on another display shelf. This is done by determining.

  In the example of FIG. 1, the determination apparatus 100 extracts position information B07 to B13 that are position information satisfying the determination criterion A03 among the position information acquired until the user U01 reaches the office from the store. To memorize. Then, the determination apparatus 100 discards, without storing, the position information that does not satisfy the determination reference A03 among the position information acquired during the time when the user U01 reaches from the store to the office.

  As described with reference to FIG. 1, the determination apparatus 100 according to the embodiment acquires position information indicating the position of the user U01, and information on positioning of the position. Further, the determination apparatus 100 determines whether or not to abstract the position information based on a determination criterion corresponding to information related to positioning.

  Thereby, the determination apparatus 100 can abstract only information useful for a service or the like that uses position information. Specifically, the determination apparatus 100 can appropriately make a selection such that only useful information is extracted and stored in the storage unit. In the case where the position information transmitted from the user terminal 10 is abstracted, if the determination reference corresponding to the same abstraction level is used for all the position information, the determination apparatus 100 may appropriately hold the position information. There are cases where it is impossible. Specifically, when the location information is abstracted based on the accuracy (abstraction degree) when the positioning means is GPS, the determination device 100 is acquired in the station yard or in the store. The position information may be abstracted into position information indicating that the user is in the station yard or the user is in the store. On the other hand, when the location information is abstracted based on the accuracy when the positioning means is beacon, the determination apparatus 100 determines almost all the acquired location information as useful information, and appropriate abstraction is performed. It may not be In contrast, when the determination apparatus 100 according to the embodiment acquires position information from the user terminal 10, information related to position measurement (for example, the positioning unit used when the user terminal 10 measures the position) is used. By acquiring and abstracting position information based on one or a plurality of determination criteria according to positioning, it is possible to appropriately select position information. That is, the determination apparatus 100 can efficiently obtain position information.

  The information indicating the position in the position information according to the embodiment includes various types of information such as numerical values of latitude and longitude, vertical altitude, speed, horizontal accuracy, vertical accuracy, angle, and error, for example. May be. For example, in a predetermined situation, the determination apparatus 100 may select and store various information such as storing altitude in the storage unit as well as numerical values indicating latitude and longitude. Further, in a predetermined situation, the user terminal 10 may select and acquire various pieces of information such as acquiring altitude as well as numerical values indicating latitude and longitude as position information. For example, when the user is located in a high-rise object such as an office or located in a high place such as a mountain, the user terminal 10 may appropriately acquire altitude as position information.

  “Terminal ID” and “User ID” correspond to the same items shown in FIG. “Position information” indicates information including the position of the user detected by the user terminal 10.

  “Acquisition date and time” indicates the date and time when the position was detected (positioned) by the user terminal 10. “Position” indicates a specific position of the user (in other words, the user terminal 10). In FIG. 7, the position is described by the concept of "G01", but in actuality, specific information (for example, numerical values of longitude and latitude, etc.) indicating the position of the user is stored in the item of position. .

  “Precision” indicates the accuracy of the information indicating the position of the user. In the embodiment, the accuracy is indicated in three stages, for example, “low”, “medium”, and “high”. The accuracy is stored, for example, according to the accuracy with which the position of the user can be specified based on the positioning means when the position is detected by the user terminal 10. Specifically, in the case of positioning means (for example, when the positioning means is only GPS) in which an error of several tens of meters to several hundreds of meters occurs when specifying the position of the user, the acquired position information The accuracy is "low". In addition, in the case of positioning means (for example, when the positioning means is a combination of Wi-Fi, GPS, etc., etc.) with high accuracy compared with the position information whose accuracy is “low”, acquisition by the acquisition means The accuracy of the position information is “medium”. In addition, in the case of a positioning means (for example, when the positioning means uses Bluetooth (beacon) etc.) with high accuracy compared with the position information whose accuracy is "medium", it is acquired by the acquisition means The accuracy of the position information is “high”.

Specific information acquired by various sensors is stored.

  That is, FIG. 7 shows that, as an example of data stored in the position information storage unit 123, the position information acquired from the user U01 identified by the terminal ID “C01” is stored. An example of the position information of the user U01 is that the user U01 is located at the position “G01” at the acquisition date “T01”, the accuracy of the position is “low”, and the various sensor information is “X01”. It shows. The position information of the user U01 held in the position information storage unit 123 next to the position information is that the user U01 is located at the position “G06” at the acquisition date “T06”, and the accuracy of the position is “low”. It indicates that the various sensor information is "X06". This indicates that the determination apparatus 100 discards the position information acquired from the acquisition date “T02” to the acquisition date “T05” without holding it in the position information storage unit 123.

  The user ID according to the embodiment is, for example, a service ID (user account) or the like commonly given to the user in each service provided by the determination apparatus 100. The determination apparatus 100 associates the position information acquired from the user terminal 10 with the user by using identification information that uniquely identifies the user. Such an ID may be issued not only by the determination apparatus 100 but also by a business operator (predetermined service provider) affiliated with the determination apparatus 100. Thereby, even when one user is using a plurality of user terminals 10 or logs in to a service in a different environment, the determination apparatus 100 uniquely identifies the user and acquires position information. Can do. Note that the determination apparatus 100 may use, as user identification information, cookie information when using the service, a terminal ID unique to the terminal, or the like.

(About the control unit 130)
The control unit 130 is, for example, a controller, and various programs (corresponding to an example of a determination program) stored in a storage device in the determination device 100 are executed by the CPU or the MPU using a RAM as a work area. Realized. The control unit 130 is a controller, and is realized by an integrated circuit such as an ASIC or FPGA, for example.

  As illustrated in FIG. 4, the control unit 130 includes an acquisition unit 131, a determination unit 132, and a storage unit 133, and implements or executes information processing functions and operations described below. Note that the internal configuration of the control unit 130 is not limited to the configuration illustrated in FIG. 4, and may be another configuration as long as the information processing described below is performed. Further, the connection relationship of each processing unit included in the control unit 130 is not limited to the connection relationship illustrated in FIG. 4, and may be another connection relationship.

  As described above, each processing unit related to the control unit 130 is realized by executing control information (for example, a determination program according to the embodiment) using the RAM as a work area. That is, the processing executed by the acquisition unit 131 is realized by the acquisition procedure executed by the control information, the processing executed by the determination unit 132 is realized by the determination procedure executed by the control information, and the processing executed by the storage unit 133 is This is realized by a storage procedure executed by the control information.

(About acquisition unit 131)
The acquisition unit 131 acquires position information from the user terminal 10. For example, the acquisition unit 131 acquires position information transmitted from the user terminal 10 that is the position information acquired by the user terminal 10 according to the control of the application installed in the user terminal 10.

  In addition, the acquisition part 131 acquires the information regarding the positioning of the position corresponding to the said position information with the position information. The information related to the positioning of the position is, for example, information used to specify the accuracy of the range of error in which the information indicating the position of the user can specify the whereabouts of the user. As described above, the user terminal 10 detects the position using various functions and positioning means. In general, the accuracy of the information indicating the position of the user varies depending on the means used for detection. For example, in the case of detecting the position of the user by GPS, the case of detecting the position of the user by using the communication function by Wi-Fi, and the case of detecting the position of the user by using the communication function by beacon, The accuracy of specifying the position is different. For example, when detecting the position of the user using the communication function by beacon, it is possible to specify the position of the user with an accuracy of several meters, such as where in the building the user is located. On the other hand, when detecting the position of the user by GPS, it is difficult to specify the position of the user with an accuracy of several meters, such as where in the building the user is located. Generally, the use of highly accurate position information makes it possible to more accurately identify the topography, route, etc., where the user has moved, and therefore, it is possible to provide a service with high usability. For this reason, for example, the determination apparatus 100 assumes that position information with high accuracy is high in value, and determines whether or not to store the position information in the storage unit 120 based on a determination criterion different from position information with low accuracy.

  As described above, the acquisition unit 131 may acquire, as the information on the accuracy of the position, the information on the positioning means when the position is detected. And the acquisition part 131 acquires the information which matched the position and the positioning means (in other words, precision) as position information. In this case, the acquisition unit 131 may previously acquire definition information that defines the relationship between the positioning means and the accuracy. Specifically, the acquisition unit 131 acquires definition information that the accuracy of the position information detected using the beacon function is “high” from the administrator of the determination apparatus 100 or the like. Then, when acquiring the information about the position and the positioning means from the user terminal 10, the acquiring unit 131 associates the information of the accuracy according to the positioning means with the position, and acquires the correlated information as the position information It is also good.

  Also, as described above, the position information may be acquired by using a plurality of positioning means in combination. Depending on the specifications of the user terminal 10, one piece of position information is not transmitted to the determination apparatus 100, but may be transmitted to the determination apparatus 100 as position information different for each positioning unit. In this case, the acquisition unit 131 acquires, over a predetermined time, position information when the position of the user is measured by the first positioning means and the second positioning means with high accuracy with respect to the first positioning means. You may make it do.

  In the example shown in FIG. 1 and the like, the first positioning means corresponds to GPS, and the second positioning means corresponds to Wi-Fi. Then, if the first positioning means can not measure that the user has moved, and the second positioning means can determine that the user has moved, the determination unit 132, which will be described later, performs the second positioning. You may make it determine with memorize | storing in the memory | storage part 120 the positional information which shows the position measured by the means. For example, in the first positioning means, it is assumed that the movement of the user can not be measured only by moving a few meters because the accuracy of specifying the position of the user is low. And the 2nd positioning means shall be able to measure the movement of the same user. Specifically, according to the second positioning means, the information indicating a certain continuous position is different (indicating that the user is located at a different position), whereas the first positioning means For example, it is assumed that information indicating a certain continuous position is substantially the same (indicating that the user is located at substantially the same position). In such a case, the determination unit 132 discards the position information acquired by the first positioning unit and holds the position information acquired by the second positioning unit. Thereby, the determination part 132 can hold | maintain more useful positional information preferentially.

  The acquisition unit 131 may acquire sensor information corresponding to the position information together with the position information. The sensor information is various information detected by the detection unit 14 of the user terminal 10. For example, the user terminal 10 detects the position of the user and also detects surrounding voice information, acceleration, temperature, humidity, and the like. The acquisition unit 131 acquires the sensor information detected together with the position from the user terminal 10 in this way.

  Moreover, the acquisition part 131 may acquire the various information regarding a user with position information. For example, the acquisition unit 131 acquires user attribute information based on information registered in each service by the user via an application to be used. In addition, the acquisition unit 131 may acquire interest interest information of the user in the application or action history information of the user. The acquisition unit 131 may acquire various pieces of information using various existing technologies (for example, an advertisement distribution technology for distributing advertisements based on user interests and actions). Further, the acquisition unit 131 may acquire position information together with date and time information including day of the week information.

  Further, the acquisition unit 131 may acquire the communication status between the user terminal 10 and another device as the position information. Specifically, the acquisition unit 131 acquires the communication status in which the user terminal 10 is accessing the Internet or the like through the access point. In this case, the acquisition unit 131 acquires information detected from the communication status with the access point as position information. Specifically, the acquisition unit 131 determines the installation position of the access point in communication with the user terminal 10, and acquires the position information of the user terminal 10 based on the determined installation position of the access point. Good. Further, the acquisition unit 131 may acquire the position of the user terminal 10 by detecting communication between the station ticket gate device and the user terminal 10 or may acquire the position based on the IP address of the user terminal 10. Good.

(About the determination unit 132)
The determination unit 132 determines whether to abstract the position information based on the determination criterion corresponding to the information on the positioning acquired by the acquisition unit 131. The abstraction of the position information means, for example, a process of thinning out a part of the acquired position information or extracting and leaving a part of the acquired position information. That is, the determination unit 132 determines whether or not the storage unit 120 stores the position information acquired by the acquisition unit 131 as a plurality of determination criteria corresponding to the information related to positioning as abstraction of the position information. Whether or not to store the position information in the storage unit 120 is determined based on the determination criterion.

  For example, the determination unit 132 determines in a stepwise manner whether or not to store the position information in the storage unit 120 using a plurality of determination criteria having different conditions depending on information related to positioning. Specifically, in the determination as to whether or not the position information is stored, the determination unit 132 stores the position information in the storage unit 120 based on a plurality of determination criteria corresponding to the positioning means when the position information is acquired. It is determined whether or not to store. For example, as illustrated in FIG. 1, the determination unit 132 does not uniformly hold or discard the position information by using different judgment criteria A01 to A03 for each acquired position information, but positioning. Performs a step-by-step decision process according to the means or location of the user.

  In addition, the determination unit 132 is configured such that the acquisition unit 131 uses the first positioning unit and the position determined by using the second positioning unit with high accuracy with respect to the first positioning unit. When the position information is acquired, it may be determined whether or not the position information is to be stored in the storage unit 120 based on the determination criterion corresponding to the second positioning means. That is, the determination unit 132 determines whether or not to store the position information by preferentially using the determination reference corresponding to the positioning means defined as the positioning means with higher accuracy.

  Further, as described above, the determination unit 132 cannot determine that the user has moved with the first positioning means in the plurality of pieces of position information measured over a predetermined time, and the second positioning means does not allow the user to If it is possible to measure movement, it may be determined to store in the storage unit 120 position information indicating the position measured by the second positioning means. In this way, the determination unit 132 preferentially holds useful position information by accurately determining information stored in the storage unit 120 based on a plurality of determination criteria, and appropriately discards unnecessary position information. be able to.

  In addition, the determination unit 132 sets a reference distance according to the positioning means, and when the user moves beyond the reference distance within a predetermined time, stores the position information of the user within the predetermined time in the storage unit 120. It may be determined to be stored. As shown in FIG. 1 and FIG. 6, the determination unit 132 holds the reference distance (500 meters, 100 meters, 1 meter, etc.) different for each positioning means at an appropriate interval for each positioning means. Position information to be determined can be determined. Specifically, even if the position information acquired by the positioning means with low accuracy is positioned when the user moves within a range of several meters, the moving distance is assumed to be within the range of an error, so storage It can be said that the necessity to hold in the part 120 is low. On the other hand, the position information acquired by the positioning means with high accuracy can accurately grasp that the user has moved within a range of several meters. According to the position information acquired by the high-precision positioning means, for example, behavior analysis such as specifying a product that causes the user to stop in the store can be performed. For this reason, the determination unit 132 determines that there is a high need for holding in the storage unit 120 the position information acquired by the positioning means with high accuracy.

(About the storage unit 133)
The storage unit 133 stores the position information determined to be stored in the storage unit 120 by the determination unit 132 in the storage unit 120. For example, the storage unit 133 stores, in the position information storage unit 123, the position information determined to satisfy the determination criteria. On the other hand, the storage unit 133 discards the position information determined not to satisfy the determination criterion.

[5. Processing procedure)
Next, a procedure of processing performed by the determination apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 8 is a flowchart showing a processing procedure according to the embodiment.

  As shown in FIG. 8, the determination apparatus 100 determines whether or not position information has been acquired from the user terminal 10 (step S101). When the position information has not been acquired (step S101; No), the determination apparatus 100 waits until acquisition.

  On the other hand, when position information is acquired (step S101; Yes), the determination apparatus 100 specifies the positioning means when position information is detected (step S102). And the determination apparatus 100 determines whether the acquired positional information satisfy | fills the determination criteria according to a positioning means (step S103).

  When it is determined that the acquired position information satisfies the determination criterion (step S103; Yes), the determination apparatus 100 stores the acquired position information in the storage unit 120 (step S104). On the other hand, when it is determined that the acquired position information does not satisfy the determination criterion (step S103; No), the determination apparatus 100 discards the acquired position information without storing it in the storage unit 120 (step S105).

[6. (Modification)
The processing according to the above-described embodiment may be implemented in various different forms other than the above-described embodiment. Hereinafter, another embodiment of the determination system 1 will be described.

[6-1. Execution of judgment program by user terminal]
In the said embodiment, the example which the determination apparatus 100 performs the determination process which concerns on embodiment according to control by the determination program which concerns on embodiment was shown. Here, the determination program according to the embodiment may be executed by the user terminal 10. That is, the determination process according to the embodiment may be performed by the user terminal 10.

  This point will be described with reference to FIG. FIG. 9 is a diagram illustrating a configuration example of a user terminal 10A according to a modification. As illustrated in FIG. 9, the user terminal 10A includes a determination unit 164. Although not shown in FIG. 9, the storage unit 15 stores information stored in the determination criteria storage unit 122 according to the embodiment.

  Moreover, in a modification, each process part which concerns on the control part 16 is implement | achieved when control information (for example, determination program which concerns on embodiment) is performed by using RAM as a work area. That is, the processing executed by the acquisition unit 161 is realized by the acquisition procedure executed by the control information, the processing executed by the reception unit 162 is realized by the reception procedure executed by the control information, and the processing executed by the transmission unit 163 is The control information is realized by a transmission procedure to be executed, and the process executed by the determination unit 164 is realized by a determination procedure to be executed by the control information.

  The determination unit 164 according to the modification performs the same process as the determination unit 132 according to the embodiment. Specifically, the determination unit 164 determines whether to store the position information acquired by the acquisition unit 161 in the storage unit, which is a determination criterion corresponding to the information related to positioning acquired by the acquisition unit 161. Whether or not to store the position information in the storage unit is determined based on the determination criterion. Note that the storage unit according to the modification may be the storage unit 120 according to the determination apparatus 100 or the storage unit 15 according to the user terminal 10A. That is, the user terminal 10A acquires position information and determines whether or not to hold the acquired position information by its own device.

  In addition, the transmitting unit 163 extracts the position information determined to be stored in the storage unit by the determining unit 164, and transmits the extracted position information to an external device having a function of storing the position information in the storage unit. Also good. The external device having the function of storing the position information in the storage unit is, for example, the determination device 100. That is, the user terminal 10A may perform the determination process and transmit only the position information determined to be stored in the storage unit to the determination apparatus 100. As a result, the user terminal 10A does not have to execute unnecessary transmission processing such as transmitting position information to be discarded, so that the load of information processing can be reduced.

  Next, the procedure of processing by the user terminal 10A according to the modification will be described with reference to FIG. FIG. 10 is a flowchart showing the processing procedure according to the modification.

  As shown in FIG. 10, the user terminal 10A determines whether or not the position of its own device has been detected (step S201). When the position has not been detected (step S201; No), the user terminal 10A stands by until the position is detected.

  On the other hand, when the position is detected (step S201; Yes), the user terminal 10A specifies the positioning means when the position is detected (step S202). Then, the user terminal 10A determines whether or not the acquired position information satisfies a determination criterion corresponding to the positioning unit (step S203).

  When it is determined that the acquired position information satisfies the determination criterion (step S203; Yes), the user terminal 10A determines to store the acquired position information in the storage unit (step S204). Then, the user terminal 10A transmits the position information to a server (for example, the determination device 100) (step S205).

  On the other hand, when it is determined that the acquired position information does not satisfy the determination criterion (step S203; No), the user terminal 10A determines that the acquired position information is not stored in the storage unit (step S206). In this case, the user terminal 10A discards the position information without transmitting it to the server (step S207).

  Note that the user terminal 10A can realize the above-described processing by an arbitrary method. For example, the user terminal 10A is an application including control information (script) for performing the above determination process and the like in advance (a control application for collectively controlling the behavior of a plurality of applications installed in the user terminal 10A) The above determination process may be realized by executing. Alternatively, the user terminal 10A may execute the determination process as described above as one piece of control information (script) incorporated in an SDK (Software Development Kit) or an OS (Operating System). Note that such control information corresponds to the determination program according to the embodiment, and, for example, CSS (Cascading Style Sheets), JavaScript (registered trademark), HTML, or any of the above described determination processes can be described. It is realized by any language or any program.

[6-2. Configuration of user terminal]
In the above embodiment, the configuration example of the user terminal 10 (or the user terminal 10A) has been described using FIG. However, the user terminal 10 does not necessarily have to include all the processing units illustrated in FIG. 3. For example, the user terminal 10 may not necessarily include the input unit 12 and the display unit 13. The user terminal 10 may be separated into two or more devices, and the configuration illustrated in FIG. 3 may be realized. For example, the user terminal 10 may be realized by two or more devices having a configuration in which a detection device having at least a detection unit 14 and an acquisition unit 161 and a communication device having at least a communication unit 11 are separated. .

[6-3. Control information)
In the modified example, the example in which the user terminal 10A executes the determination process according to the control information in which the determination program according to the embodiment is described is shown. Here, the control information may be included in the application executed by the user terminal 10A, may be included as one function of the web browser software, or is included in the application to be displayed on the user terminal 10A. May be. That is, the acquisition source and the distribution source of the control information do not affect the result of the determination process performed by the user terminal 10A.

[6-4. Information on positioning)
In the above-described embodiment, the position positioning unit is taken as an example of the information regarding the position positioning. Also, it has been described that each positioning means has different accuracy (abstraction degree) of the information indicating the position. Here, the accuracy of the positioning means is not limited to the example shown in the above embodiment. For example, depending on the positioning means used by the user terminal 10, positioning accuracy using GPS may be higher in position accuracy than positioning using Wi-Fi or beacon. That is, the accuracy of the positioning means shown above and the accuracy of the positioning means is an example, and the judgment program according to the embodiment has various judgment criteria that differ according to the user terminal 10 to be judged and the positioning means. Conditions may be set.

[6-5. (Criteria)
In the above-described embodiment, the example in which the distance or angle moved by the user is set as the condition as the criterion is shown. Here, the determination criterion is not a specific numerical value as described above, but may be a movement determination model for the user. For example, the determination program learns a model for determining whether the user is currently at home or at work based on the context of the user. The determination program may use a model generated as a result of learning as a determination criterion.

  For example, when the position is determined by GPS, the determination program determines that the context switch timing is the acquisition timing of the position information. Specifically, the determination program acquires position information when it is determined that the user is at home based on the acquired context. Thereafter, the determination program does not acquire position information while it is determined that the user is at home. The determination program newly acquires position information when it is determined that the user has started moving to a position different from the home based on the acquired context. In other words, the determination program may determine such context transition based on the learned model, not the distance traveled by the user or the remaining time. Accordingly, the determination program realizes the determination process according to the embodiment by acquiring and learning the daily position information of the user without setting specific numerical values such as time and distance in advance. be able to.

  Moreover, although the example in which the determination criterion according to the information regarding positioning was provided was shown in the said embodiment, the determination criteria may not necessarily correspond to the information regarding positioning. For example, the determination program may determine the abstraction of the position information using the determination criteria corresponding to the context of the user as described above. That is, the acquisition procedure according to the determination program acquires position information indicating the position of the user. Then, the determination procedure according to the determination program may determine whether or not to abstract the position information of the user based on the user context specified from the position information.

  Specifically, the determination program specifies the user's context using the learning model as described above. Specifically, the determination program specifies a context in which the user's location is the user's home, a station, or a workplace. Note that the determination program may specify the user's context (location in this example) using a data table that associates the latitude / longitude information with the building or map information associated with the latitude / longitude information. Then, the determination program uses the determination criteria corresponding to the context (for example, the determination criteria A01 for the user's home, the determination criteria A02 for the station, etc.) to determine whether the location information is abstracted or not. Do. Thus, the determination program can perform appropriate determination processing without using information related to positioning (for example, positioning means).

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. It can be integrated and configured. For example, the determination unit 132 and the storage unit 133 illustrated in FIG. 4 may be integrated.

  In addition, the above-described embodiments and modifications can be combined as appropriate within a range that does not contradict processing contents.

Etc.

  For example, when the computer 1000 functions as the determination device 100 according to the embodiment, the CPU 1100 of the computer 1000 realizes the function of the control unit 130 by executing the program loaded on the RAM 1200. The HDD 1400 stores data in the storage unit 120. The CPU 1100 of the computer 1000 reads these programs from the recording medium 1800 and executes them, but as another example, these programs may be acquired from the other device via the communication network 500.
