As shown in FIG. 1, the optimal application presentation device 1 can communicate with the mobile terminal 3 via the network 2, and includes an optimal application calculation unit 10, a storage unit 11, an application usage history acquisition unit 12, and an optimal application request. The receiving unit 13 and the optimum application information transmitting unit 14 are included. The optimum application calculation unit 10 includes a position determination unit 21, a scoring processing unit 22, and a sorting unit 23. The storage unit 11 includes an application usage history DB 31, a default application DB 32, and an application information DB 33. .

  First, the application usage history DB 31, the default application DB 32, and the application information DB 33 in the storage unit 11 will be described.

  The application usage history DB 31 is a database in which history data that is a usage history of an application (application) is stored. Specifically, as shown in the application usage history DB 401 of FIG. 4A, the ID of the used application, the used location information (used location information) (location ID (name information), latitude, longitude, altitude Error distance), use time (use date / time information), and user attributes (gender, age) are associated with each other and stored as history data. The place ID identifies a specific place, and is associated with, for example, a restaurant, a movie theater, a landmark, or the like.

  In the application usage history DB 401 shown in FIG. 4A, the application A is used at the latitude “34.0000”, the longitude “135.0000”, the altitude (m) “0”, and the error distance (m) “100”. (UTC) stores “1323405720000”, the age of the user is “20”, and the gender of the user is “male”. The same applies to app B, app C,. The error distance is information indicating the error of the used position, and is information that accompanies when the position is specified.

  The default application DB 32 is a database of default data that is a characteristic of an application stored in advance in the optimum application presentation device 1. Specifically, as shown in the default application DB 402 in FIG. 4B, the application ID, location information appropriate for use (location ID, latitude, longitude, altitude, error distance), age appropriate for use, Gender is stored in association with each other.

  In the default application DB 402 shown in FIG. 4B, the application A has a place ID “place A”, latitude “34.0000”, longitude “135.0000”, altitude (m) “0”, error distance (m) “10”, Stored in association with the age “0 to 200” and the gender “male”. The same applies to app B, app C,.

  The default application DB 402 stores a plurality of the same applications at different locations. For example, in the example shown in the default application DB 402, two applications A and D are stored. This is to cope with a case where the same application can be used at a plurality of stores at different places, such as an application usable for a chain store.

  The application information DB 33 is a database that stores applications. Specifically, as shown in the application DB 403 of FIG. 4C, the application ID, name, stored location, and application description are stored in association with each other.

  In the application DB 403 shown in FIG. 4C, the application with the application ID “application A” is the application name “application A name”, the storage location (application URL) “http: // ***. “***” is stored in association with each other. The same applies to app B, app C,.

  The application usage history acquisition unit 12 stores application usage log information # 2a (history data) acquired from the mobile terminal 3 via the network 2 in the application usage history DB 31. The application usage log information # 2a includes the ID of the application being used, the location being used (location ID, latitude, longitude, altitude), and the attribute information (age, gender) of the user being used. Yes.

  The application usage log information # 2a is transmitted from the mobile terminal 3 to the optimum application presentation device 1 by installing a resident application having the following functions in order to transmit an application usage history to the mobile terminal 3, for example. can do. The resident application monitors the activation and termination of the application, and when the application is activated, the application information (application ID), the location of the mobile terminal 3 acquired from the GPS 5 or WiFi base station 6, and the current time are registered in advance. The attribute information (age, gender) of the user is transmitted to the optimum application presentation device 1 via the network 2 as application usage log information # 2a.

  When receiving the optimum application request information # 2b (application information request) from the mobile terminal 3 via the network 2, the optimum application request receiving unit 13 sends the received optimum application request information # 2b to the optimum application calculating unit 10. The optimum application request information # 2b includes the location (request location) of the mobile terminal 3 (location ID, or latitude, longitude, altitude, error information) and attribute information. The optimum application request information # 2b is stored in the portable terminal 3 when the optimum application presentation application (see display example 201 in FIG. 2) is activated and the current location selection screen (see display example 202 in FIG. 2) is selected. It is transmitted from the terminal 3 to the optimum application presentation device 1.

  The information indicating the location of the mobile terminal 3 differs in the content included in the optimum application request information # 2b depending on whether or not the user has checked in. That is, when the user performs check-in, the location ID is included in the optimum application request information # 2b. When the user does not check in, the latitude, longitude, altitude, and error information include the optimum application request information # 2b. include.

  Upon receiving the optimum application request information # 2b, the optimum application calculation unit 10 ranks the applications and transmits the results to the optimum application information transmission unit 14. The optimum application calculation unit 10 includes the position determination unit 21, The configuration includes a scoring unit 22 and a sort unit 23.

  The position determination unit 21 uses the information on the current location included in the optimum application request information # 2b, and among the applications stored in the application usage history DB 31 and the default application DB 32, the position information is within a predetermined range from the current location. Extract the history data of the included applications. Then, information indicating the extracted history data of the application is transmitted to the scoring processing unit 22.

  More specifically, when the location information of the optimal application request information # 2b includes a location ID, the location determination unit 21 corresponds to the same location ID as the location ID included in the optimal application request information # 2b. The attached application history data is extracted from the application usage history DB 31 and the default application DB 32.

  In addition, when the location information of the optimum application request information # 2b does not include a location ID and includes latitude, longitude, altitude, and error distance, it is used within a predetermined range from the current location indicated by the location information. The history data of the application including the position indicated by the received location information or the location information appropriate for use (hereinafter simply referred to as location information when both are included) is extracted. Specifically, this will be described with reference to FIG.

In FIG. 5, the position indicated by the position information included in the optimum application request information # 2b is the current position, and the position indicated by the place information is the registered position. Each of the position information and the location information includes an error distance, and the distances are d ₁ and d ₂ . Assuming a sphere having a radius d1 centered on the current position and a sphere having a radius d2 centered on the registered position, the history data of the application having the registered position within a range where these two spheres overlap is obtained from the current location. Extracted as history data of an application in which the position indicated by the location information is included in the range. The sphere is assumed because of the concept that location information and location information include altitude.

  The scoring unit 22 uses the application history data received from the position determination unit 21 to calculate the score (recommended degree) of the application. Specifically, the difference (age difference, gender difference) between each of the extracted application history data and the optimum application request information # 2b, and the difference (time difference) between the current time and the use time included in the additional information of the application ) To calculate the score.

  This will be described in more detail with reference to FIG. FIG. 6 is a graph showing a time difference scoring function for deriving points from the time difference. In the graph shown in FIG. 6, the vertical axis is the score and the horizontal axis is the time difference. When the time difference is “0”, the score is “1”, and the score decreases as the time difference increases. It has become. According to this function, the score is calculated from the time difference, and the calculated score is set as the time difference score of the application.

  The age difference and the gender difference are calculated using the same function (a function in which the score decreases as the difference increases). And the average score of each calculated score is calculated, and the calculated average score is transmitted to the sorting unit 23 as the score of the application.

  As a result, the time difference is smaller, that is, the more recently used application, the higher the score, the higher the score of the application that matches the latest trend. Similarly, when the age of the user who has requested the presentation of the optimal application (the user who started the optimal application presentation application) and other users using the application are similar and have the same gender, the score of the application increases. Therefore, the number of applications used by people of the same generation and family name can be increased.

  The sorting unit 23 sorts the applications in the order of the scores based on the application scores received from the scoring processing unit 22, and transmits the results to the optimum application information transmitting unit 14. More specifically, the application rank, the score, the information on the application stored in the application information DB 33, and the individual score (time difference, age difference, sex difference) of the application are transmitted to the optimum application information transmission unit 14.

  The optimum application information transmission unit 14 transmits the result received from the sorting unit 23 to the portable terminal 3 via the network 2 as the optimum application information # 10.

[Flow of processing in optimal application presentation device 1]
Next, the flow of processing in the optimum application presentation device 1 will be described with reference to FIGS. Upon receiving the optimum application request information # 2b, the optimum application presentation device 1 scores (a) the application extracted from the application usage history DB 31, (b) scores the application extracted from the default application DB 32, and (c) these Are merged and output (d).

(A) Scoring of applications from application usage history DB 31 FIG. 7 is a flowchart showing the flow of processing when scoring applications extracted from the application usage history DB 31.

  As illustrated in FIG. 7, the optimum application calculation unit 10 receives optimum application request information # 2b (location ID, position (latitude, longitude, altitude), user attributes (age, gender)) from the optimum application request reception unit 13. Then, the current time is acquired (S1, application information request acquisition step), and it is determined whether or not “location ID” exists (S2). When the “location ID” exists (NO in S2), the position determination unit 21 extracts a matching location ID from the applications in the application usage history DB 31 (S3, application extraction step). On the other hand, when the “location ID” does not exist (S2 YES), the position determination unit 21 extracts an application whose registered position is within a predetermined range from the current location from the application usage history DB 31 (S4, application extraction step).

  When the application is extracted in step S3 or step S4, the scoring unit 22 calculates the score of the application from the extracted application and the optimum application request information # 2b (S5). That is, for each extracted application, the difference between the current time and the use time indicated by the extracted additional information of the application is calculated, and the difference value is substituted into the time difference scoring function to calculate the score according to the time difference. Similarly, the difference between the age included in the user attribute information and the age included in the extracted additional information of the application is calculated, converted into an absolute value, substituted into the age difference scoring function, and the score according to the age difference Is calculated. Further, the score is calculated from the difference between the gender included in the user attribute information and the gender included in the extracted additional information of the application.

  Then, the scoring processing unit 22 calculates the average score of the scores calculated for each item for the same application name, and calculates the score of the application (S6, app recommendation degree determination step). Specifically, this will be described with reference to FIG. FIG. 8 is an explanatory diagram when data is extracted from the application usage history DB 31 and the score of the application is calculated. Data 801 in FIG. 8A is a diagram showing the score for each of the applications extracted in steps S3 and S4. In the data 801, application A, application B, application C, application A, application B, application C,..., Application X are extracted. In the application A in the first row, the time difference score is “1”, the age difference score is “0.2”, and the gender difference score is “1”. The same applies to app B, app C,.

  Since the application usage history DB 31 is an application usage history, the same application may be included multiple times. Therefore, the average score is calculated for the same application. In the data 801, the result of collecting the same applications is data 802 shown in FIG. In the data 802, the number of uses, usage frequency, score, and average score are shown for each application. Here, the number of times of use indicates the number of times the data 801 appears, the frequency of use indicates the ratio in the data 801, the time difference score, the age difference score, and the gender difference score each indicate an average score in the application, The total average score indicates the average score of usage frequency, time difference score, age difference score, and gender difference score.

  In the example shown in the data 802, the application A is “400”, that is, appears 400 times in the data 801, and the usage frequency is “0.4”, that is, the application A is used in 40% of the total. It is shown that. In addition, the time difference score is “0.6”, the age difference score is “0.4”, the gender difference score is “0.2”, and the total average score is “0.4”. The total average score is the score of the application, and becomes the reference point when sorting. The same applies to app B, app C,.

  The above is the flow of processing when scoring the application extracted from the application usage history DB 31.

(B) Scoring of applications from the default application DB 32 Next, the flow of processing when an application is extracted from the default application DB 32 and scored will be described with reference to FIG. FIG. 9 is a flowchart showing the flow of processing when scoring the application extracted from the default application DB 32.

  As illustrated in FIG. 9, the optimum application calculation unit 10 receives optimum application request information # 2b (location ID, position (latitude, longitude, altitude), user attributes (age, gender)) from the optimum application request reception unit 13. Then (S21, application information request acquisition step), it is determined whether or not “location ID” exists (S22). When the “location ID” exists (NO in S22), the position determination unit 21 extracts a matching location ID from the applications in the default application DB 32 (S23, application extraction step). On the other hand, when the “location ID” does not exist (S2 YES), the position determination unit 21 extracts an application whose registered position is within a predetermined range from the current location from the default application DB 32 (S24, application extraction step).

  When the application is extracted in step S23 or step S24, the scoring processing unit 22 calculates the score of the application from the extracted application and the optimum application request information # 2b (S25, application recommendation degree determination step). That is, for each extracted application, the difference between the age included in the user attribute information and the age included in the additional information of the extracted application is calculated, converted to an absolute value, and assigned to the age difference scoring function. A score corresponding to the difference is calculated. Further, the score is calculated from the difference between the gender included in the user attribute information and the gender included in the extracted additional information of the application.

  Then, the scoring unit 22 calculates the average score of the scores calculated for each item for the same application name, and calculates the score of the application (S26).

  Specifically, a description will be given with reference to FIG. FIG. 10 is an explanatory diagram when the application is extracted from the default application DB 32 and the score is calculated. Data 1001 in FIG. 10A is a diagram showing scores for each of the applications extracted in steps S23 and S24. In the data 1001, application A, application B, application C, application A, application B, application C,..., Application X are extracted. In the application A in the first row, the age difference score is “0.2” and the gender difference score is “1”. The same applies to app B, app C,.

  As described above, the default application DB 32 stores a plurality of the same applications with different locations. Therefore, the same application may be extracted multiple times. Therefore, the average score is calculated for the same application. As for the data 1001, the result of collecting the same applications is the data 1002 shown in FIG. The data 1002 shows the age difference score, gender difference score, and total average score for each application. The app A has an age difference score of “0.4”, a gender difference score of “1”, and a total average score. Is “0.7”. The same applies to app B, app C,.

  The above is the flow of processing when scoring the application extracted from the default application DB 32.

(C) Merging Next, the flow of the process of merging the points calculated in the above (a) and (b) and transmitting them to the mobile terminal 3 will be described with reference to FIG.

  The sorting unit 23 includes the score of the application extracted from the application usage history DB 31 calculated by the scoring processing unit 22 in (a) and the score of the application extracted from the default application DB 32 calculated in (b). Is obtained (S41), a weight is calculated (S42), and each score is weighted (S43).

  Here, the weight will be described with reference to FIG. FIG. 12 is a diagram for explaining merging of the application score extracted from the application usage history DB 31 and the application score extracted from the default application DB 32. FIG. 12A does not show the number of applications extracted from the application usage history DB 31. FIG. 12B is a diagram showing the number of applications extracted from the default application DB 32. FIG. 12C is a diagram showing the points weighted to the points shown in FIG. 12A, and FIG. 12D is a diagram showing the points weighted to the points shown in FIG. FIG. 12E is a diagram illustrating the scores after merging and sorting the scores for each application.

  Then, the weight is obtained by dividing the total number S of application usage extracted from the application usage history DB 31 by 10,000. That is, weight = total S / 10000. For example, in the example shown in the data 1201 in FIG. 12A, if the total number of uses of application A, application B,... Is 1000, the weight is 1000/10000 = 0.1. Then, the score of the application extracted from the application usage history DB 31 is multiplied by 1.1 (= 1 + 0.1), and the score of the application extracted from the default application DB 32 is multiplied by 0.9 (= 1−0.1). To do.

  Therefore, as shown in the data 1201 of FIG. 12A, the total average score of the application A extracted from the application usage history DB 31 is “0.4”, the total average score of the application B is “0.3”, the application C If the total average score of “0.2”,..., And the total average score of the app X is “0.6”, the weighted score is calculated by the app A as shown in the data 1203 in FIG. “0.44”, app B is “0.33”, app C is “0.22”,..., App X is “0.66”.

  Further, as shown in the data 1202 of FIG. 12B, the total average score of the application A extracted from the default application DB 32 is “0.6”, the total average score of the application B is “0.4”, the application C If the total average score of “0.2”,..., And the total average score of the app X is “0.6”, the weighted score is calculated by the app A as shown in the data 1204 in FIG. “0.54”, app B is “0.36”, app C is “0.18”,..., App X is “0.54”.

  When the number of uses exceeds 10,000, the weight is set to “1” and the weight is not allowed to exceed “1”.

  As described above, as the use history is accumulated in the application usage history DB 31 by weighting, the weight of the application extracted from the application usage history DB 31 becomes higher and the application history is extracted from the default application DB 32. Application weight is low. Therefore, when the usage history is not accumulated in the application usage history DB 31, the data of the default application DB 32 is used, and the data of the application usage history DB 31 is used as the usage history is accumulated in the application usage history DB 31. Thus, the number of applications suitable for the usage form can be increased.

  When the weighted score is calculated for each application in step S43, the sorting unit 23 calculates the average score of the same application (S44), and sorts the applications by the average score (S45).

  In the example shown in FIG. 12, in the data 1203 of FIG. 12C, the app A has “0.44” points, the app B has “0.33” points, the app C has “0.22” points, X is “0.66”, and in the data 1204 of FIG. 12D, application A is “0.54”, application B is “0.36”, application C is “0.18”, Since application X is “0.54”, the average score for each application is “0.49” for application A, “0.345” for application B, “0.20” for application C, and application X Becomes “0.6” point.

  Therefore, when these are sorted, as shown in the data 1205 in FIG. 12E, the first is the application X, the score is “0.6”, the second is the app A, and the score is “0.49”. The third is the application B, and the score is “0.345”.

(D) Output When the applications are sorted in step S45, the optimum application information transmission unit 14 transmits optimum application information # 14 indicating the calculation result to the mobile terminal 3 (S46, application recommendation degree information transmission step). The contents of the optimum application information # 14 transmitted by the optimum application information transmitting unit 14 are shown in FIG. As shown in data 1301 in FIG. 13, the optimum application information # 14 includes applications arranged in the order of scores, application scores, application information (application ID, application name, application URL, application description), and application usage history DB 31. Each information and score when extracted from (number of use, frequency of use, time difference score, age difference score, gender difference score), each score (age difference score, gender difference score) when extracted from the default application DB32 The associated data.

〔Concrete example〕
For example, without checking in, the current position (longitude: east longitude 135.00000, latitude: north latitude 34.00000, altitude: 0, error distance: 100 m), user attributes (age: 30, gender: male) are acquired from the mobile terminal 3. In the case of the current time (1323405720000), the optimum application presentation device 1 performs the following process.

  (Procedure 1) First, the application data is scored using the history data extracted from the application usage history DB 31.

  In this example, since the check-in is not performed and there is no data of the location ID, the optimal application presentation device 1 and the current position acquired from the mobile terminal 3 and the registered position (longitude, latitude, altitude, The history data registered within the ranges of longitude: east longitude 135.00000, latitude: north latitude 34.00000, altitude: 0, and error distance: 100 m are extracted from the application usage history DB 31.

  Next, for each extracted history data, a difference between the current time and the use time of each extracted history data is obtained, and a difference value is substituted into the time difference scoring function to calculate a score corresponding to the time difference. Further, a difference between the acquired age and the age of each extracted history data is obtained, converted into an absolute value, and substituted into an age difference scoring function to calculate a score corresponding to the age difference. Further, the acquired gender and the extracted history data genders are compared and substituted into a gender difference scoring function to calculate a score corresponding to the gender difference.

  Next, with respect to the time difference, age difference, and gender difference score of each history data, the scores of the same application name are summed to calculate an average score. Therefore, the calculated average score is a time difference average score, an age difference average score, and a gender difference average score. Furthermore, the usage frequency of each application is calculated, and the average score of the four points of usage frequency, time difference average score, age difference average score, and gender difference average score is calculated.

  (Procedure 2) Next, the application is scored with reference to the default application DB.

  In this example, since the check-in is not performed and there is no place ID data, the optimum application presenting apparatus 1 determines the current position acquired from the mobile terminal 3 and the registered position (longitude, latitude, altitude, error) of the default application DB 32. The default data registered within the ranges of longitude: east longitude 135.00000, latitude: north latitude 34.00000, altitude: 0, and error distance: 100 m are extracted from the default application DB 32.

  Next, for each extracted default data, compare the acquired age with the age of each extracted default data to find the difference, convert it to an absolute value, substitute it into the age difference scoring function, and respond to the age difference Calculate the score. Also, the obtained gender and the gender of each extracted default data are compared and substituted into a gender difference scoring function to calculate a score corresponding to the gender difference. Further, an average score between the age difference score and the gender difference score is calculated.

  (Procedure 3) Finally, in “Procedure 1”, refer to “the application scored by referring to the history data extracted from the application usage history DB 31” and in “Procedure 2” refer to “Default data extracted from the default application DB 32”. And calculate the average score with the application that has been scored and sort it in descending order. Then, as a result of “scoring by referring to the history data extracted from the application usage history DB 31” in the above (procedure 1), the mobile terminal 3 refers to “default data extracted from the default application DB 32” in the above (procedure 2). As a result, the result “sorted in descending order of the score” and “application information” are transmitted.

  In the above-described embodiment, the configuration including the default application DB 32 is described. However, the optimal application may be calculated using only the application usage history DB 31 without using the default application DB 32. .

[Appendix 1]
In the above-described embodiment, the case where an optimal application is presented has been described, but the present invention is not limited to this. The present invention can be applied to contents such as electronic books and WEB services instead of applications.

[Appendix 2]
In the embodiment described above, when checking in, only the target location for the check-in is a requirement for extracting data from the database. However, the present invention is not limited to this. For example, when the check-in target is a chain store In addition, it may be configured to extract data (history data, default data) of the same chain store.

  This can be realized by storing the chain store information (group information) indicating the same chain store in the application usage history DB 31 and the default application DB 32 in association with the location ID indicating the chain store.

  In addition to the chain stores, the data of stores in the same category may be extracted, or the user attribute information may include friend information and the data having the same friend information may be extracted. .

[Appendix 3]
Moreover, when the category of an application and the category of the check-in target match, weighting may be performed so that the score of the application is increased. For example, when checking in a golf course, weighting may be performed so as to increase the number of golf-related applications and sports-related applications.

  This can be realized by including a category information storage unit in which the place ID and the category are associated with each other and storing the application and the category including the application in the application usage history DB 31 and the default application DB 32.

[Appendix 4]
Further, even when the check-in is not performed, if the location can be identified from the position information, the same processing as that performed when checking in the location may be performed.

  This can be realized by providing a location information storage unit that associates location information with a location ID. Note that the position information and the place ID do not have to correspond one-to-one, and all the position information included in a certain range may correspond to the same place ID.

[Appendix 5]
In the above-described embodiment, data extraction is performed using the current location and the error distance, but without using the error distance, the range specified by the user (for example, within the vicinity of XX km, within XX prefecture) A configuration for extracting data may also be used. For example, when Nara Prefecture is designated, in the application usage history DB 31 and the default application DB 32, the place information indicating the Nara prefecture is extracted. Whether or not it is within Nara Prefecture may be configured such that “Nara Prefecture” is designated by the place ID and this is extracted, or a configuration in which latitude / longitude indicates within Nara Prefecture may be extracted.

  This can be realized by including range designation information for designating the extraction range in the optimum application request information # 2b.

[Appendix 6]
The configuration may be such that the mobile terminal 3 automatically downloads the application when a required application is not installed in the mobile terminal 3 when the user checks in.

  Moreover, the optimal application presentation apparatus 1 may be configured to be connectable to a communication network, and the program code may be supplied via the communication network. The communication network is not particularly limited as long as it can transmit the program code. For example, the Internet, intranet, extranet, LAN (local area network), ISDN (integrated services digital network), VAN (value-added network), CATV (community antenna television) communication network, virtual private network (virtual private network), A telephone line network, a mobile communication network, a satellite communication network, etc. can be used. The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type. For example, infrared data such as IrDA (infrared data association) or remote control can be used for wired such as IEEE (institute of electrical and electronic engineers) 1394, USB, power line carrier, cable TV line, telephone line, ADSL (asynchronous digital subscriber loop) line, etc. , Bluetooth (registered trademark), IEEE 802.11 wireless, HDR (high data rate), NFC (Near Field Communication), DLNA (Digital Living Network Alliance), mobile phone network, satellite line, terrestrial digital network, etc. Is possible. The present invention can also be realized in the form of a computer data signal embedded in a carrier wave in which the program code is embodied by electronic transmission.
