  However, in the above-mentioned conventional technique, it is not always possible to efficiently acquire the position information. Specifically, in the above-mentioned conventional technique, the position information of the user to be analyzed is used to analyze the behavior of a small number of users. However, if the position information is to be acquired in order to analyze the behaviors of an extremely large number of users, the amount of information will be enormous. Therefore, if the position information is simply uniformly acquired from all the users, the communication load and the information processing cost increase.

  The present application has been made in view of the above, and an object thereof is to provide a determination program, a determination apparatus, and a determination method that can efficiently acquire position information.

  The determination program according to the present application abstracts the position information based on position information indicating the position of the user, an acquisition procedure for acquiring information regarding positioning of the position, and a determination criterion corresponding to the information regarding the positioning. The computer is caused to execute a determination procedure for determining whether or not.

Also, in each of the following embodiments, the same parts are designated by the same reference numerals, and duplicate description will be 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. FIG. 1 illustrates an example of a determination process executed by the determination device 100, which is an example of a computer that operates according to the determination program according to the embodiment. Specifically, in FIG. 1, the determination device 100 acquires position information indicating the position of the user and information regarding the degree of abstraction of the position, and based on a plurality of determination criteria corresponding to the acquired information regarding the degree of abstraction. Then, an example of performing a process of determining whether or not to abstract the 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 the identification information for identifying each user and the information indicating the position of each user in association with each other, and stores the acquired information as position information. For example, the determination device 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. In addition, the determination device 100 provides various services by using the position information. In the embodiment, the determination device 100 provides, for example, a service related to a navigation application that provides traffic guidance using the 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 device 100 may provide the acquired position information and the like to other businesses that provide various services.

  The user terminal 10 shown in FIG. 1 is an information processing terminal such as a smartphone. In the embodiment, the user terminal 10 is used by the user U01, which is an example of the user. In the following, the user terminal 10 may be read as a user. For example, “the user U01 transmits the position information” may actually mean that “the user terminal 10 used by the user U01 transmits the position information”.

  The user terminal 10 detects the position where the own device is located (for example, the numerical value of longitude and latitude) by using a positioning unit that measures the position such as GPS (Global Positioning System), and information indicating the detected position. To get the location information. 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, under the control of the application used. Specifically, the user terminal 10 periodically and continuously transmits the position information to the determination device 100 according to the control (function) of the navigation app or the portal app that is an app managed by the determination device 100. The position information transmitted from the user terminal 10 is accumulated in the storage unit included in the determination device 100 and used for various information processing.

  As described above, the user terminal 10 acquires the detected position and transmits the position information corresponding to the acquired position to the determination device 100. However, the transmission of the acquired position information to the determination device 100 is performed regularly and continuously from all the user terminals 10 that use the service, and thus the position information acquired by the determination device 100 becomes a huge amount of information. .. Therefore, it is desirable that the determination device 100 not store the position information in the storage unit at random, but store only the position information useful for providing the service. In other words, the determination device 100 preferably abstracts and holds the position information. Note that in the embodiment, the abstraction of position information means, for example, when a plurality of position information indicates a position where a specific user is located, a predetermined number from the plurality of position information is given so as not to affect information processing. This is the process of removing (thinning). Further, the abstraction of position information means that even if a plurality of different position information is considered to have no significant effect on information processing, the position information is rounded (considered as information indicating the same position). It can be said that the whole information amount is compressed by.

  Therefore, the determination device 100 according to the embodiment acquires, together with the position information, information regarding the degree of abstraction of the position in the position information indicating the position of the user. Then, the determination apparatus 100 determines whether or not to abstract the position information based on a plurality of determination criteria corresponding to the information regarding the degree of abstraction. More specifically, the determination device 100 determines whether or not to store the acquired position information in the storage unit, which is a plurality of determination criteria corresponding to the information regarding the degree of abstraction, as the abstraction of the position information. It is determined whether or not the position information is stored in the storage unit based on the determination criterion of. By such control, the determination apparatus 100 can extract and store only useful position information, and thus it is possible to prevent the storage capacity from being exhausted due to the accumulation of position information. In other words, the determination device 100 can efficiently acquire the position information. Note that the information regarding the degree of abstraction of the position is based on how much the position information is held in the storage unit (that is, the determination device 100 does not hold all the acquired position information, but all the acquired position information). It is information that serves as a guide indicating the position information (how to extract position information that does not pose a problem even if abstracted) that is assumed to have no problem in information processing even if discarded. In the embodiment, the information regarding the degree of abstraction of the position is, for example, information regarding the positioning when the user terminal 10 measures the position of the user. For example, the information regarding 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 identifying the position of the user varies depending on the positioning means for positioning the position, the information processing capability of the terminal device for acquiring the position information, and the like. That is, the information regarding positioning is, for example, the positioning means used when the user terminal 10 measures the position, the information indicating the error range of the measured position, and the information processing of the user terminal 10 that acquires the position information. Ability, etc. The flow of the determination process according to the embodiment will be described below with reference to FIG.

  In the example of FIG. 1, the user terminal 10 detects position information according to the function of a predetermined application installed by the user U01, and also transmits position information corresponding to the detected position to the determination device 100. For example, the user terminal 10 detects the position of its own device using a predetermined positioning means every 10 minutes, and transmits the position information to the determination device 100.

  Here, the determination device 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 judgment criteria.

  For example, the accuracy of the position differs depending on the positioning means used when the position is detected by the user terminal 10. In the example of FIG. 1, the user terminal 10 can use a positioning means using GPS satellites (hereinafter simply referred to as “GPS”). In addition, the user terminal 10 specifies a position of its own device by measuring a distance to a base station or an access point of each communication company via a Wi-Fi (registered trademark) communication function (hereinafter, simply referred to as “positioning means”). Wi-Fi”). In addition, the user terminal 10 uses the Bluetooth (registered trademark) function of the user terminal 10 to connect with a beacon transmitter or the like, thereby determining the position of the own device (hereinafter simply referred to as “Bluetooth”). Or, or written as "beacon") can be used.

  The determination device 100 has different determination criteria for each positioning means as described above. Then, the determination device 100 determines whether to abstract the position information acquired from the user terminal 10 by using different determination criteria according to the positioning unit when the position information is acquired by the user terminal 10. .. For example, the determination apparatus 100 determines which of the positional information acquired from the user terminal 10 is thinned out or which positional information is left by using the determination criterion. More specifically, the determination device 100 determines whether to store the position information acquired from the user terminal 10 in the storage unit, using the determination standard.

  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. It is also assumed that the accuracy when the position is measured by the beacon is higher than the accuracy when the position is measured by the Wi-Fi. Further, in the embodiment, the determination device 100 uses the determination criterion corresponding to the positioning device with higher accuracy when the position information is acquired by using the plurality of positioning devices.

  For example, in FIG. 1, it is assumed that the user terminal 10 acquires position information by using the GPS as a positioning unit until the user U01 leaves his/her 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 device 100 makes a determination using the determination standard A01, which is the determination standard corresponding to GPS, in the acquired position information. For example, the determination criteria A01 include "(has the target (user U01 in the example of FIG. 1) moved 500 meters or more?" or "has 1 hour or more passed (from the most recently detected position)?" The condition for storing the position information is included.

  Such a criterion is provided in order 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 GPS has low 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, all the positions thereof are acquired. Information is unlikely to be useful. In other words, as the position information acquired by the GPS, relatively rough movement information of the user U01 (for example, a number) until the user U01 leaves his/her home and arrives at a specific base (station in the example of FIG. 1). It can be said that it is sufficient to show the position information indicating the movement every 100 meters.

  Therefore, for the position information detected by using the GPS, the determination device 100 determines whether or not to store the position information by using the determination reference A01 provided with a relatively rough reference. In the example of FIG. 1, the determination apparatus 100 determines that the position information B01, the position information B02, and the position that are the position information satisfying the determination criterion A01 among the position information acquired by the user U01 from his/her home to the station. The information B03 is extracted as the held information. Then, the determination device 100 stores the extracted position information in the storage unit. On the other hand, the determination device 100 discards, without storing, the position information that does not satisfy the determination criterion A01 among the position information acquired until the user U01 arrives at the station from his/her home.

  Subsequently, the user terminal 10 is assumed to acquire position information using Wi-Fi as a positioning means from when the user U01 reaches the station to the specific store in the station. For example, when the environment in which the user terminal 10 can use Wi-Fi is prepared in the station yard, the user terminal 10 can acquire position information by using Wi-Fi as a positioning unit. Note that the user terminal 10 may use the position detection using GPS together 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 device 100 performs the determination using the determination criterion A02 which is the determination criterion corresponding to Wi-Fi in the acquired position information. For example, the criterion A02 is provided with criteria such as "(has the target moved 100 meters or more?" and "has a movement other than a straight line (from the most recently detected position) made?"

  For example, since the position information acquired by Wi-Fi has higher accuracy than the position information acquired by GPS only, it may be useful to acquire the transition of the position of the user U01 within a certain range. Is high. In addition, in a station or the like where Wi-Fi can be used, an administrator may utilize location information such as acquiring location information of each user and analyzing the behavior of the user. That is, when the position information can be acquired by Wi-Fi, it may be required to acquire detailed position information regarding the user's action as compared with GPS, so the condition is detailed as compared with the determination criterion A01. The determination criterion A02 provided is adopted. It should be noted that the determination as to whether or not the user's movement is a straight line is performed by, for example, expressing between the two points at the most recent position and the two points at the next acquired position as vectors and forming both vectors. It can be determined by whether or not the angle exceeds a predetermined threshold value.

  In the example of FIG. 1, the determination apparatus 100 determines that the position information B04, the position information B05, and the position that are position information satisfying the determination criterion A02 among the position information acquired by the user U01 from the station until reaching the store. The information B06 is extracted and stored. Then, the determination device 100 discards, without storing, the position information that does not satisfy the determination criterion A02 among the position information acquired by the time the user U01 reaches the store from the station.

  Subsequently, the user terminal 10 is assumed to acquire the position information using the beacon as the positioning means from the time the user U01 enters the store to the office. For example, when the beacon for analyzing the behavior of the user who has visited is arranged on each of the display shelves of the store, the user terminal 10 can acquire the position information by using the beacon as the positioning means. If possible, the user terminal 10 may use the beacon together with the position detection using Wi-Fi or GPS. Then, the user terminal 10 transmits the acquired position information to the determination device 100 every predetermined time.

  In this case, the determination device 100 performs the determination using the determination criterion A03 which is the determination criterion corresponding to beacon among the acquired position information. For example, the criteria A03 include criteria such as "(has moved by 1 meter or more?)" and "(has moved to another display rack) (from the most recently detected position)?".

  For example, since the position information acquired by beacon is more accurate than the position information acquired by Wi-Fi or GPS, the user U01 can determine what kind of display shelf (product) the user U01 is looking at. It is possible to analyze the detailed transition of the position of. That is, when the position information is acquired based on the beacon, it is necessary to hold more detailed position information regarding the behavior of the user as compared with Wi-Fi or GPS, and thus the condition is compared with the determination criterion A02. A more detailed determination criterion A03 is adopted. Whether or not the user has moved to another display shelf is determined by, for example, that the communication with the user terminal 10 has switched from beacon installed in the display shelf to another beacon installed in another display shelf. It is performed by determining.

  In the example of FIG. 1, the determination device 100 extracts the location information B07 to B13 that is the location information that satisfies the determination criterion A03 from the location information acquired by the user U01 from the store until reaching the office. To remember. Then, the determination device 100 does not store the position information that does not satisfy the determination criterion A03 among the position information acquired by the user U01 from the store until reaching the office, and discards it.

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

  As a result, the determination apparatus 100 can abstract only information that is useful for services that use position information. Specifically, the determination device 100 can appropriately make a selection such that only useful information is extracted and stored in the storage unit. If the position information transmitted from the user terminal 10 is abstracted, if the judgment criterion corresponding to the same degree of abstraction is used for all the position information, the judgment device 100 may appropriately hold the position information. Sometimes you can't. Specifically, when the position information is abstracted based on the accuracy (abstractness) when the positioning unit is GPS, the determination device 100 acquires the position information acquired at the station premises or the position information acquired at the store. The location information may be abstracted into location information indicating that "the user is located in the station" or "the user is located in the store". On the other hand, if the position information is abstracted based on the accuracy when the positioning unit is beacon, the determination device 100 determines almost all the acquired position information as useful information, and performs the appropriate abstraction. There is a risk that you will not be discouraged. On the other hand, the determination device 100 according to the embodiment, when acquiring the position information from the user terminal 10, uses the information regarding the positioning of the position (for example, the positioning means used when the user terminal 10 measures the position). By acquiring and abstracting the position information based on one or a plurality of determination criteria according to the positioning, it is possible to appropriately select the position information. That is, the determination device 100 can efficiently acquire the 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 information. You may For example, the determination device 100 may select and store various information in a predetermined situation, such as storing not only numerical values indicating latitude and longitude but also altitude in a storage unit. Further, in a predetermined situation, the user terminal 10 may select and acquire various information as position information, such as acquiring not only numerical values indicating latitude and longitude but also altitude. For example, the user terminal 10 may appropriately acquire the altitude as the position information when the user is located in a high-rise object such as an office or in a high altitude place such as a mountain.

  Hereinafter, the determination device 100 or the like that executes the determination process described above according to the determination program according to the embodiment will be described in detail.

Further, the connection relationship between the processing units included in the control unit 16 is not limited to the connection relationship illustrated in FIG. 3 and may be another connection relationship.

(About the acquisition unit 161)
The acquisition unit 161 acquires various information. For example, the acquisition unit 161 acquires various information detected by the detection unit 14 by controlling the detection unit 14. For example, the acquisition unit 161 acquires the position information of the user terminal 10 based on the information detected by the position detection unit 142.

At this time, the transmission unit 163 may transmit the position information every time the acquisition unit 161 acquires the position information, or may transmit the position information every predetermined period. For example, even if the transmission unit 163 periodically (every 1 minute, 3 minutes, 5 minutes, 1 hour, etc.) acquires the position information by the acquisition unit 161, the transmission unit 163 does not operate at preset time intervals. Alternatively, the position information may be transmitted to the determination device 100 or the like.

The storage unit 120 includes a user information storage unit 121, a determination reference storage unit 122, and a position information storage unit 123.

(About the user information storage unit 121)
The user information storage unit 121 stores information about users. Here, FIG. 5 illustrates an example of the user information storage unit 121 according to the embodiment. FIG. 5 is a diagram illustrating an example of the user information storage unit 121 according to the embodiment. As shown in FIG. 5, the user information storage unit 121 has items such as “user ID”, “terminal ID”, and “attribute information”.

  “User ID” indicates identification information for identifying a user. The “terminal ID” indicates identification information for identifying the user terminal 10 used by the user. Each user may own a plurality of terminals. Further, in the embodiment, the identification information may be used as a reference symbol used for the description. For example, the user identified by the user ID “U01” may be described as “user U01”.

  The “attribute information” indicates information regarding the attribute of the user. In FIG. 5, the attribute information is represented by a concept such as “D01”, but in reality, various specific information such as the age, sex, occupation, annual income, place of residence of the user is included in the attribute information item. Is memorized.

  That is, in FIG. 5, as an example of data stored in the user information storage unit 121, the user U01 indicated by the user ID “U01” is using the user terminal 10 identified by the terminal ID “C01”. Is shown. It also indicates that the attribute information of the user U01 is “D01”.

  Although not shown in FIG. 5, the user information storage unit 121 stores the interest information of the user, the action history of the user, and the like based on the usage history of the service (website or the like) or the application. May be done. For example, the interest/interest information is information set to the user by the determination device 100 through the use of a service or an application (a category that the user is supposed to have an interest from the purchase history or search history of the user, Information content). Further, the behavior history information is a behavior history of a user in a service or an application (movement history based on a navigation application, history of destination, browsing history of web pages, purchase history of products, search history, etc.).

(Regarding Judgment Criteria Storage Unit 122)
The criterion storage unit 122 stores the criterion used in the determination process according to the embodiment. Here, FIG. 6 illustrates an example of the determination criterion storage unit 122 according to the embodiment. FIG. 6 is a diagram illustrating an example of the determination criterion storage unit 122 according to the embodiment. As shown in FIG. 6, the determination criterion storage unit 122 has items such as “determination criterion ID”, “positioning means”, and “condition”.

  “Judgment criteria ID” indicates identification information for identifying the judgment criteria. “Positioning means” is a means used when detecting the position of the user, and indicates a positioning means associated with each criterion. The “condition” indicates the specific content of the condition for storing the position information in the storage unit 120. For example, the determination device 100 stores the position information in the storage unit 120 when the acquired position information satisfies any of the conditions.

  That is, in FIG. 6, as an example of the data stored in the determination reference storage unit 122, the determination reference A01 indicated by the determination reference ID “A01” is a reference used when the positioning means is “GPS”. As the conditions, for example, "movement of 500 meters or more" or "more than one hour has passed since the latest information" is set.

(Regarding the position information storage unit 123)
The position information storage unit 123 stores the position information transmitted from the user terminal 10. Here, FIG. 7 illustrates an example of the position information storage unit 123 according to the embodiment. FIG. 7 is a diagram illustrating an example of the position information storage unit 123 according to the embodiment. In the example shown in FIG. 7, the position information storage unit 123 has items such as “terminal ID”, “user ID”, and “position information”. Further, the item of "positional information" has small items such as "acquisition date and time", "position", "accuracy", and "various sensor information".

  The “terminal ID” and the “user ID” correspond to the same item shown in FIG. The “position information” indicates information including the position of the user detected by the user terminal 10.

  The “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 represented by a concept such as “G01”, but in reality, the position item stores specific information indicating the position of the user (for example, a numerical value of longitude and latitude). ..

  "Accuracy" indicates the accuracy of the information indicating the position of the user. In the embodiment, the accuracy is indicated by three levels of “low”, “medium”, and “high”, for example. The accuracy is stored according to the accuracy with which the position of the user can be specified, for example, based on the positioning unit when the position is detected by the user terminal 10. Specifically, in the case of a positioning unit (for example, when the positioning unit is only GPS) where an error of several tens to several hundreds of meters occurs when specifying the position of the user, the acquired position information The accuracy is "low". Further, in the case of a positioning device having higher accuracy than the position information having low accuracy (for example, when the positioning device is a combination of Wi-Fi, GPS, etc.), it is acquired by the acquisition device. The accuracy of the obtained position information is "medium". Further, in the case of a positioning means having a higher accuracy than the position information with the accuracy of “medium” (for example, when the positioning means uses Bluetooth (beacon) etc.), it is acquired by the acquisition means. The accuracy of the position information is “high”. Note that the above-described accuracy determination is an example, and the determination device 100 may flexibly change the accuracy determination criterion according to the positioning technology of position information. Further, the accuracy according to the embodiment may be read as the positioning means.

  “Various sensor information” indicates information detected by various sensors when the position is detected. In FIG. 7, various sensor information is expressed by a concept such as “X01”, but in reality, various sensor information items include acceleration and altitude of the user terminal 10, temperature and humidity, surrounding voice information, and the like. Specific information acquired by various sensors is stored.

  That is, FIG. 7 shows that the position information acquired from the user U01 identified by the terminal ID “C01” is stored as an example of the data stored in the position information storage unit 123. Further, 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 and time “T01”, the accuracy of the position is “low”, and the various sensor information is “X01”. Shows. Further, the position information of the user U01 held in the position information storage unit 123 next to the position information indicates that the user U01 is located at the position “G06” at the acquisition date and time “T06” and the accuracy of the position is “low”. Yes, it indicates that the various sensor information is “X06”. This means that the determination device 100 does not hold the position information acquired from the acquisition date “T02” from the acquisition date “T05” in the position information storage unit 123, but discards it.

  The user ID according to the embodiment is, for example, a service ID (user account) or the like commonly given to users in each service provided by the determination device 100. The determination device 100 associates the location information acquired from the user terminal 10 with the user by using the identification information that uniquely identifies the user. The ID may be issued not only by the determination device 100 but also by a business operator (a predetermined service provider) affiliated with the determination device 100. Accordingly, the determination device 100 uniquely identifies the user and acquires the position information even when one user uses the plurality of user terminals 10 or logs in to the service in different environments. You can The determination device 100 may use, as the user identification information, cookie information when the service is used, a terminal ID unique to the terminal, or the like.

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

  As illustrated in FIG. 4, the control unit 130 includes an acquisition unit 131, a determination unit 132, and a storage unit 133, and realizes or executes the information processing function or action described below. The internal configuration of the control unit 130 is not limited to the configuration shown in FIG. 4, and may be another configuration as long as it is a configuration for performing information processing described later. The connection relationship between the processing units 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, the determination program according to the embodiment) using the RAM as a work area. That is, the process executed by the acquisition unit 131 is realized by the acquisition procedure executed by the control information, the process executed by the determination unit 132 is realized by the judgment procedure executed by the control information, and the process executed by the storage unit 133 is executed. , Is realized by the storage procedure executed by the control information.

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

  The acquisition unit 131 acquires the position information and the information regarding the positioning of the position corresponding to the position information. The information regarding the positioning of the position is, for example, information used for specifying the accuracy of how much error the information indicating the position of the user can specify the location of the user. As described above, the user terminal 10 detects the position by 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, in the case of detecting the position of the user by using the communication function by Wi-Fi, and in the case of detecting the position of the user by using the communication function by beacon, The accuracy of identifying the position is different. For example, when the position of the user is detected using the communication function using the beacon, the position of the user can be specified with accuracy within a range of several meters, such as where in the building the user is located. On the other hand, when the position of the user is detected by GPS, it is difficult to specify the position of the user with accuracy within a range of several meters such as where in the building the user is located. In general, the use of highly accurate position information allows the user to more accurately specify the topography, route, and the like, so that it is possible to provide a service with high usability. Therefore, for example, the determination device 100 assumes that highly accurate position information has a high value, and determines whether or not to store it in the storage unit 120 based on a determination criterion different from that of low accuracy position information.

  As described above, the acquisition unit 131 may acquire, as the information regarding the position accuracy, the information regarding the positioning unit when the position is detected. Then, the acquisition unit 131 acquires, as the position information, information in which the position and the positioning means (in other words, accuracy) are associated with each other. In this case, the acquisition unit 131 may acquire in advance definition information that defines the relationship between the positioning means and the accuracy. Specifically, the acquisition unit 131 acquires, from the administrator of the determination device 100 or the like, definition information that the accuracy of the position information detected by using the beacon function is “high”. Then, when the acquisition unit 131 acquires the information about the position and the positioning means from the user terminal 10, the accuracy information corresponding to the positioning means is associated with the position, and the associated information is acquired as the position information. Good.

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

  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, when the first positioning means cannot measure that the user has moved and the second positioning means can measure that the user has moved, the determination unit 132, which will be described later, determines the second positioning. It may be determined that the storage unit 120 stores the position information indicating the position determined by the means. For example, it is assumed that the first positioning means is inferior in the accuracy of identifying the position of the user, and therefore the user cannot measure the position of the movement only by several meters. Then, the second positioning means is assumed to have been 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), while the first positioning means For example, it is assumed that the information indicating a certain continuous position is substantially the same (indicating that the user is located at almost the same position). In such a case, the determination unit 132 discards the position information acquired by the first positioning unit and retains the position information acquired by the second positioning unit. Thereby, the determination unit 132 can preferentially hold more useful position information.

  The acquisition unit 131 may acquire the position information and the sensor information corresponding to 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, from the user terminal 10, the sensor information thus detected together with the position.

  In addition, the acquisition unit 131 may acquire various pieces of information regarding the user together with the position information. For example, the acquisition unit 131 acquires the attribute information of the user based on the information registered by the user in each service via the application used. Further, the acquisition unit 131 may acquire the interest information of the user in the application and the action history information of the user. The acquisition unit 131 may acquire various information by using various existing technologies (for example, an advertisement distribution technology for distributing an advertisement based on the user's interest and behavior). Further, the acquisition unit 131 may acquire the position information together with the date and time information including the 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 via the access point. In this case, the acquisition unit 131 acquires information detected from the communication status with the access point as the position information. Specifically, the acquisition unit 131 may determine the installation position of the access point in communication with the user terminal 10 and acquire it as the position information of the user terminal 10 based on the calculated installation position of the access point. Good. In addition, 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 or not to abstract the position information based on the determination standard corresponding to the information regarding the positioning acquired by the acquisition unit 131. The position information abstraction is, 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, as an abstraction of the position information, whether to store the position information acquired by the acquisition unit 131 in the storage unit 120, which is a plurality of determination criteria corresponding to information regarding positioning. It is determined whether or not the position information is stored in the storage unit 120 based on the determination criterion for

  For example, the determination unit 132 uses a plurality of determination criteria having different conditions depending on the information regarding positioning, and determines in stepwise whether or not to store the position information in the storage unit 120. Specifically, in determining whether or not to store the position information, 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 uses the determination criteria A01 to A03 that are different for each of the acquired position information, and does not uniformly hold or discard the position information, but performs positioning. A stepwise determination process is performed according to the means and the location of the user.

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

  In addition, as described above, the determination unit 132 cannot position that the user has moved with the first positioning unit in the plurality of position information items that have been positioned over a predetermined period of time, and the user cannot use the second positioning unit with the position of the user. When it is possible to measure the movement, it may be determined that the storage unit 120 stores the position information indicating the position measured by the second positioning unit. In this way, the determination unit 132 determines the information stored in the storage unit 120 based on a plurality of determination criteria, preferentially holds useful position information, 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, the position information of the user within the predetermined time is stored in the storage unit 120. You may decide to memorize. As shown in FIG. 1 and FIG. 6, the determination unit 132 retains the reference distances (500 meters, 100 meters, 1 meter, etc.) that are different for each positioning means, at appropriate intervals for each positioning means. It is possible to determine the position information to be used. Specifically, the position information acquired by the positioning device with low accuracy is stored because the moving distance is assumed to be within the error range even if the position is measured when the user moves within a range of several meters. It can be said that the necessity of holding the inside of the portion 120 is low. On the other hand, the position information acquired by the highly accurate positioning means can accurately grasp that the user has moved within a range of several meters. According to the position information acquired by the highly accurate positioning means, it is possible to perform an action analysis such as, for example, identifying a product that causes the user to stop in the store. Therefore, the determination unit 132 determines that it is highly necessary to store the position information acquired by the highly accurate positioning unit in the storage unit 120.

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

[5. Processing procedure]
Next, a procedure of processing performed by the determination device 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 illustrated in FIG. 8, the determination device 100 determines whether or not the position information has been acquired from the user terminal 10 (step S101). When the position information is not acquired (step S101; No), the determination device 100 waits until it acquires it.

  On the other hand, when the position information is acquired (step S101; Yes), the determination device 100 specifies the positioning means when the position information is detected (step S102). Then, the determination device 100 determines whether or not the acquired position information satisfies the determination criterion according to the positioning means (step S103).

  When it is determined that the acquired position information satisfies the determination criterion (step S103; Yes), the determination device 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 criterion (step S103; No), the determination device 100 does not store the acquired position information in the storage unit 120 and discards it (step S105).

[6. Modification example)
The process 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 above embodiment, the example in which the determination device 100 performs the determination process according to the embodiment under the control of the determination program according to the embodiment has been described. 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 the user terminal 10A according to the modification. As shown in FIG. 9, the user terminal 10A has a determination unit 164. Although illustration is omitted in FIG. 9, the storage unit 15 stores information stored in the determination reference storage unit 122 according to the embodiment.

  Further, in the modification, each processing unit related to the control unit 16 is realized by executing the control information (for example, the determination program according to the embodiment) using the RAM as a work area. That is, the process executed by the acquisition unit 161 is realized by the acquisition procedure executed by the control information, the process executed by the reception unit 162 is realized by the reception procedure executed by the control information, and the process executed by the transmission unit 163 is realized. The control procedure is implemented by the transmission procedure executed by the control information, and the process performed by the determination unit 164 is implemented by the determination procedure 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 regarding the positioning acquired by the acquisition unit 161. It is determined whether or not the position information is stored in the storage unit based on the determination criterion for The storage unit according to the modification may be the storage unit 120 of the determination device 100 or the storage unit 15 of the user terminal 10A. That is, the user terminal 10A acquires the position information and determines whether or not to retain the acquired position information by itself.

  In addition, the transmission unit 163 extracts the position information determined to be stored in the storage unit by the determination unit 164, and transmits the extracted position information to an external device having a function of storing the position information in the storage unit. 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 may transmit only the position information determined to be stored in the storage unit to the determination device 100. As a result, the user terminal 10A does not have to perform useless transmission processing such as transmitting the discarded position information, and thus can reduce the information processing load.

  Next, a 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 a 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 is not detected (step S201; No), the user terminal 10A waits 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 the determination criterion according to the positioning means (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 the server (for example, the determination device 100) (step S205).

  On the other hand, when determining 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).

  The user terminal 10A can realize the above-described processing by an arbitrary method. For example, the user terminal 10A is an application (control application that collectively controls the behavior of a plurality of applications installed in the user terminal 10A, which includes an application including control information (script) for executing the above-described determination process in advance. The above determination process may be realized by executing (1). Alternatively, the user terminal 10A may execute the above determination processing as one of the control information (scripts) incorporated in the SDK (Software Development Kit) or the 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 determination processes described above can be described. It is realized by the 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 with reference to FIG. However, the user terminal 10 does not necessarily need to include all the processing units illustrated in FIG. For example, the user terminal 10 does not necessarily have to include the input unit 12 and the display unit 13. Further, the user terminal 10 may be separated into two or more devices to realize the configuration shown in FIG. For example, the user terminal 10 may be realized by two or more devices having a configuration in which a detection device including at least the detection unit 14 and the acquisition unit 161 and a communication device including at least the communication unit 11 are separated. ..

[6-3. Control information)
In the above modification, 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 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. Positioning information]
In the above-described embodiment, the position positioning means is taken as an example of the information regarding the position positioning. Further, it has been explained that the respective positioning means differ in the accuracy (abstraction) 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, the positioning accuracy using GPS may be higher than the positioning accuracy using Wi-Fi or beacon. That is, the above-described positioning means and the degree of accuracy of the positioning means are examples, and the determination program according to the embodiment has various different determination criteria depending on the user terminal 10 or the positioning means to be determined. A condition may be set.

[6-5. Judgment criteria]
In the above embodiment, an example in which the distance, angle, and the like moved by the user are set as conditions for the determination criteria. Here, the determination criterion may be something like a movement determination model for the user, instead of the specific numerical value as described above. 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. Then, the determination program may use the model generated as a result of learning as the determination reference.

  For example, when the position is measured by GPS, the determination program determines that the context switching timing is the position information acquisition timing. Specifically, the determination program acquires the position information when it is determined that the user is located at home based on the acquired context. After that, the determination program does not acquire the position information while it is continuously determined that the user is at home. Then, the determination program newly acquires the position information when it is determined that the user has started moving to a position different from home based on the acquired context. That is, the determination program may determine such a transition of the context based on the learned model instead of the distance traveled by the user or the staying time. Thereby, the determination program realizes the determination process according to the embodiment by acquiring the daily position information of the user and performing learning without presetting specific numerical values such as time and distance. be able to.

  Further, in the above-described embodiment, the example in which the determination criterion according to the information regarding the positioning is provided has been described, but the determination criterion may not necessarily correspond to the information regarding the positioning. For example, the determination program may use the determination criteria according to the context of the user as described above to determine the abstraction of the position information. That is, the acquisition procedure according to the determination program acquires the 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 context of the user identified from the position information.

  Specifically, the determination program uses the learning model as described above to identify the context of the user. Specifically, the determination program identifies a context such that the place where the user is located is the user's home, the station, or the work place. The determination program may use the data table that associates the latitude and longitude information with the building, or the map information that associates with the latitude and longitude information to identify the context (location in this example) of the user. Then, the determination program uses a determination criterion according to the context (for example, determination criterion A01 for the user's home, determination criterion A02 for the station, etc.) to determine whether to abstract the position information. To do. Thereby, the determination program can perform an appropriate determination process without depending on the information regarding the positioning (for example, the positioning means).

[6-6. Other]
Further, of the processes described in the above embodiment, all or part of the processes described as being automatically performed may be manually performed, or the processes described as being manually performed may be performed. All or part of the process can be automatically performed by a known method. In addition, the processing procedures, specific names, information including various data and parameters shown in the above-mentioned documents and drawings can be arbitrarily changed unless otherwise specified. For example, the various kinds of information shown in each drawing are not limited to the illustrated information.

  Further, each constituent element of each illustrated device is functionally conceptual, and does not necessarily have to be physically configured as illustrated. That is, the specific form of distribution/integration of each device is not limited to that shown in the figure, and all or a part of the device may be functionally or physically distributed/arranged 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.

  Further, the above-described embodiments and modified examples can be appropriately combined within a range in which the processing content is not inconsistent.

[7. Hardware configuration]

Send to device.

  The CPU 1100 controls output devices such as a display and a printer and input devices such as a keyboard and a mouse via the input/output interface 1600. The CPU 1100 acquires data from the input device via the input/output interface 1600. The CPU 1100 also outputs the data generated via the input/output interface 1600 to the output device.

  The media interface 1700 reads a program or data stored in the recording medium 1800 and provides the program or data to the CPU 1100 via the RAM 1200. The CPU 1100 loads the program from the recording medium 1800 onto the RAM 1200 via the media interface 1700, and executes the loaded program. The recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or PD (Phase change rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory. 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. Further, the HDD 1400 stores the 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 other devices via the communication network 500.
