  The server data processing unit 350 executes various data processing according to the application recorded in the ROM / RAM 320. In particular, the server data processing unit 350 executes a predetermined program, thereby managing the operation of the communication control unit 310, registering an action history in each communication terminal device 10, and providing recommended information providing processing for recommending information, and Management and control of the recording device 330 is performed. Specifically, the server data processing unit 350 includes a registration processing unit 351, a similarity calculation unit 352, and a recommendation information generation unit 353.

  For example, the registration processing unit 351 of the present embodiment constitutes a registration unit and an update registration unit of the present invention, and the similarity calculation unit 352 constitutes a calculation unit of the present invention. Further, for example, the recommendation information generation unit 353 of the present embodiment constitutes the specifying unit and the extracting unit of the present invention. Further details of the server data processing unit of this embodiment will be described later.

  The timer 360 is used to specify the registration time, and provides the server data processing unit 350 with the date and time when the action history information is registered in the recording device 330.

[4] Details of Server Data Processing Unit Next, details of the server data processing unit 350 in the information providing server device 30 of the present embodiment will be described.

(Registration Processing Department)
The registration processing unit 351 executes a registration process of registering each user's action history information in the action history DB 331 based on each user's instruction received via each communication terminal device 10. The registration processing unit 351 records the action history information to be registered in the influence point DB 332 when the action history information to be registered is the action history information as a result based on the recommendation information acquired by the recommendation information providing process. Update processing for updating the influence point of the corresponding service user is executed.

In particular, when the registration processing unit 351 executes the update process,
(1) The specific action history of a specific service user is distributed to the target user as recommendation information, and
(2) On condition that the same action as the specific action history distributed as recommendation information is executed by the target user,
(3) When the target user has each condition that the same action as the specific action history is executed by a preset expiration date,
The influence point DB 332 is controlled, and the influence point update registration of the service user to which the specific action history provided as recommendation information belongs is executed.

  The action history registration process may be executed every time action history information is registered in the communication terminal device 10, or may be executed at a predetermined timing such as once a day at a predetermined time. One or a plurality of action history information may be registered.

(Similarity calculator)
When the similarity calculation unit 352 receives a recommendation information acquisition request from the target user received via the communication terminal device 10, the similarity calculation unit 352 uses each cosine similarity method to record each service user recorded in the action history DB 331. Based on the behavior history information, a ratio that matches the behavior history of other users with the requested user as the target user is calculated as a similarity to each user.

  Specifically, the similarity calculation unit 352 generates a vector Q formed by TF-IDF (Term Frequency-Inverse Document Frequency) indicating the appearance frequency of the place ID based on the action history information of the target user. That is, the similarity calculation unit 352 calculates “TF-IDF (=) for each location ID calculated based on the appearance frequency“ TF ”of the location ID of the target user and the appearance frequency“ DF ”of the location ID of all service users. TF / DF) "is calculated.

The vector Q is a vector as shown in (Expression 1). In (Expression 1), “m” indicates a location ID number, and “t _j ¹ ” to “t _j ^m ” indicate calculated TF-IDF values of the respective location IDs.

  Similarly, the similarity calculation unit 352 similarly generates a vector S formed by TF-IDF indicating the appearance frequency of the place ID based on the action history information of other service users other than the target user. That is, the similarity calculation unit 352 generates “TF-IDF” for each location ID calculated based on the appearance frequency “TF” of other service users and the appearance frequency “DF” of location IDs of all service users. The vector S of (= TF / DF) is calculated.

The vector S is a vector as shown in (Expression 2). “J” indicates a user ID. In (Expression 2), “s _j ¹ ” to “s _j ^m ” are TF-IDF values of the place ID, as in (Expression 1).

Then, using the vector space model of the target user's vector “Q” and the other service user's vector (S _j ), the similarity calculation unit 352 performs the behavior of the other service user as the target user for each other user. The ratio that coincides with the history is calculated by using (Expression 3) as the similarity (sim).

(Recommendation information generator)
The recommendation information generation unit 353 specifies other service users having the given first condition based on the respective similarities calculated for the other users by the similarity calculation unit 352. Specifically, the recommendation information generation unit 353 specifies, as a specific user, another service user used when calculating the degree of similarity in which each degree of similarity is a predetermined threshold (for example, 0.5) or more. Then, the recommendation information generation unit 353 forms a pseudo group by the target user and the specific user, compares the behavior history information of these users in the pseudo group, and does not match the behavior history of the target user. The behavior history of the other service user to be determined is identified as the specific behavior history.

  In particular, the recommendation information generation unit 353 identifies the behavior history of another service user that does not match the behavior history of the target user, and from among the identified behavior history of the other service user, between the other service users. The action history whose ratio of matching action histories has a given third condition is specified. Then, the recommendation information generation unit 353 determines that the identified behavior history is inconsistent with the behavior history of the target user, and identifies the specific behavior history information.

  Note that the action history satisfying the third condition is an action history having the lowest ratio that matches the action history between other service users, that is, an action history that is “0”. However, this need not be the case.

  Also, the recommendation information generation unit 353 acquires the influence point of the specific user from the influence point DB 332, and has a given second condition from the specific action history based on each acquired influence point. The specific action history to be extracted is extracted. Specifically, the recommendation information generation unit 353 specifies a user having the highest influence point as a given second condition as a user having a high ability to transmit information, and the specific action history of the specified user is determined. Extract as recommendation information.

  Then, the recommendation information generation unit 353 distributes the specific behavior history extracted via the communication control unit 310 to the communication terminal device 10 of the target user as recommendation information together with the user ID of the service user who provided the specific behavior history. To do.

  The recommendation information generation unit 353 is not limited to the above, and may provide a list of action histories registered in association with each service user in order of service users with high influence points as recommendation information. The higher rank (three or five) may be provided as recommendation information. Further, the recommendation information generation unit 353 may transmit the recommendation information to the corresponding communication terminal device 10 at a predetermined timing such as once a day instead of the request timing of the target user.

(Example of each process until recommendation information is extracted in this embodiment)
For example, as shown in FIG. 6 and FIG. 7A, using the communication terminal device 10, the location information (that is, the location ID) of the location where the service users A to E checked in the information providing server device 30. It is assumed that the action history is transmitted to the information providing server device 30 and the registration is executed.

  In this case, when the similarity calculation unit 352 receives a recommendation information acquisition request for requesting acquisition of recommendation information from the service user A, the service user A is the target user, the action history of the service user A, and other The action histories registered in association with the service users B to E are compared, and the ratio that matches the action histories is calculated as the similarity for each other service user.

  At this time, the similarity calculation unit 352 identifies, as a given first condition, a service user B and a service C whose similarity is equal to or higher than a given threshold (for example, 0.5 or higher if cosine similarity is used). Then, a pseudo group is created by the service users A to C.

  That is, the similarity calculation unit 352 performs the above-described operations of (Expression 1) to (Expression 3), and the user B has a similarity of “0.8” to the user A, and the similarity of the user C. Since the degree is calculated as “0.6”, the similarity degree of the user D is “0.2”, and the similarity degree of the user E is 0.0, the service user B whose threshold is 0.5 or more is calculated. And C create pseudo service users A to C.

  Then, the similarity calculation unit 352 compares each behavior history information of the service user A with each behavior history information of each identified service user B and C, and determines that the behavior history of the target user does not match The user's action history is specified as the specific action history.

  For example, the similarity calculation unit 352 has a given ratio of the behavior history of the other service users B and C that does not match the service user A and the behavior history between the service users B and C matches. The place IDs “123” and “320” of the action history satisfying the three conditions “0” are determined to be inconsistent with the action history of the target user, and specified as the specific action history.

  Also, the recommendation information generation unit 353 acquires the influence points “B = 5” and “C = 3” of the service users B and C to which the specific action history belongs, and based on the acquired influence points, the specific action history As a given second condition, a user (service user B) having the highest influence point is identified, and the specific action history (location ID “123”) of the identified user is recommended information. Extract.

  Then, the recommendation information generation unit 353 distributes the specific action history extracted via the hospital control unit 310 to the communication terminal device 10 of the service user A as recommendation information.

(Step S103).

  Next, the terminal data processing unit 130 communicates with the information providing server device 30 in conjunction with the display control unit 150 and the operation unit 170 to acquire the location ID and check-in processing (that is, the device itself) A process for registering that the current position exists is executed (step S104). At this time, the terminal data processing unit 130 receives the input of the name and other information when registering as a place ID, and records in the recording unit 100 whether or not a visit is made based on the recommendation information. The check-in process may be executed in conjunction with the information providing server device 30 or another server device, or may simply be a process that is completed by the own application.

  Next, the terminal data processing unit 130 transmits the location ID for which the check-in process has been performed via the network communication unit 110 to the information providing server device 30 together with a registration request to which various data related to login to the SNS and a user ID are added. (Step S105), and this operation is terminated.

  When the terminal data processing unit 130 visits based on the recommendation information, the terminal data processing unit 130 acquires the fact and the ID of the service user who provided the recommendation information from the recording unit 100, and together with the registration request, the information providing server device 30.

  Next, in the information providing server device 30, when the registration processing unit 351 receives a registration request via the communication control unit 310 (step S201), the location ID included in the received registration request is included in the registration request. Based on the user ID, it is registered in the action history DB 331 (step S202). At this time, the registration processing unit 351340 acquires the current time from the timer 360, and registers the place ID together with the acquired time in the action history DB 331.

  Next, the registration processing unit 351 determines whether or not the registration request is a result of acting on the recommendation information, that is, whether or not the recommendation information and the user ID of the recommended user are included in the registration request (step S203). .

  At this time, if the registration processing unit 351 determines that the request is not a registration request for the result of acting on the recommendation information, the registration processing unit 351 terminates this operation, and if the registration processing unit 351 determines that the registration request is a result of the action on the recommendation information, The process proceeds to step S211.

  Next, when the registration processing unit 351 determines that the registration request is a result of acting on the recommendation information, the registration processing unit 351 refers to the recommendation information management table T2 of the influence point DB 332, and the current time is included in the registration request. It is determined whether it is before the effective period recorded in association with the ID and the user ID of the recommended user (step S211).

  At this time, the registration processing unit 351 refers to the recommended information management table T2, and the current time is not before the valid period recorded in association with the location ID included in the registration request and the user ID of the recommended user. If it is determined that it is after the valid period, this operation is terminated.

  On the other hand, if it is determined that the current time is before the valid period recorded in association with the location ID included in the registration request and the user ID of the recommended user, the influence point of the corresponding user ID in the influence information management table T2 is displayed. Converted to “1” (step S212), the operation is terminated.

S302). At this time, the terminal data processing unit 130 executes initialization of the work memory and other necessary processes, and acquires its own user ID from the management table recording unit 102.

  Next, the terminal data processing unit 130 transmits a recommendation information provision acquisition request to which the user ID is added to the information providing server device 30, and waits for reception of recommendation information (step S304).

  Next, in the information providing server device 30, when the server management control unit 340 receives a recommendation information acquisition request (step S 401), the similarity calculation unit 352 includes a user ID included in the recommendation information acquisition request. The user Q is the target user, and the vector Q is calculated based on the appearance frequency “TF” of the location ID of the target user and the appearance frequency “DF” of the location ID of all the service users while interlocking with the action history DB 331 (step) S402).

  Next, the similarity calculation unit 352 calculates the vector Sj of each service user in the same manner as in step S402 for service users other than the user ID included in the recommendation information acquisition request in conjunction with the action history DB 331 (step S403). ).

  Next, the recommendation information generation unit 353 identifies other service users whose specificities calculated by the similarity calculation unit 352 have a given first condition (for example, a predetermined value or more) as specific users. Then, a pseudo group is formed by the target user and the specific user (step S404).

  Next, the recommendation information generation unit 353 identifies the behavior history of another service user in the pseudo group that does not match the behavior history of the target user (step S405), and based on the identified behavior history of the other service user. Then, the specific action history information is specified (step S406). Specifically, the recommendation information generation unit 353 generates an action history having a given third condition with a ratio of matching action histories among other service users from the action histories of other specified service users. It is determined that the behavior history of the target user does not match, and the specific behavior history information is identified.

  Next, the recommendation information generation unit 353 acquires the influence point of the specific user from the influence point DB 332, and has a given second condition from the specific action history based on each acquired influence point. The specific action history to be extracted is extracted as recommendation information (step S407). Specifically, the recommendation information generation unit 353 specifies a user having the highest influence point as a given second condition as a user having a high ability to transmit information, and the specific action history of the specified user is determined. Extract as recommendation information.

  Next, the recommendation information generation unit 353 distributes the specific behavior history extracted through the communication control unit 310 to the communication terminal device of the target user as recommendation information together with the user ID of the service user who provided the country-specific behavior history. (Step S408), this operation is terminated.

  Next, in the communication terminal device 10, when the terminal data processing unit 130 receives the recommendation information transmitted from the information providing server device 30 (step S <b> 332), the terminal data processing unit 130 works with the display control unit 150 to display the received recommendation information as a browser. Is displayed on the display unit 140 (step S333).

  Finally, the terminal data processing unit 130 records the received recommendation information received in the recommendation information management table T2 of the management table recording unit 102 (step S334), and ends this operation.

  As described above, the communication system 1, the communication terminal device 10, and the information providing server device 30 according to the present embodiment are user behavior histories similar to the target user and serving as a transmission source of information transmission, and the target user has not yet known. Since no information can be distributed as recommendation information, it is possible for the target user to be interested and to recommend pioneering information.

  The communication system 1, the communication terminal device 10, and the information providing server device 30 frequently update the attribute value of the user who provided the recommended information when the target user performs the same action based on the recommended information. A user who provides recommendation information can be used as a pioneering user who is a source of information transmission.
