The quota count table 12C includes unique identification information [user_id] for each user and information [q_1], [q_2], [q_3], [q_4] indicating the excitement for each quota corresponding to this identification information. Are recorded. In this example, the dedicated application 37 on the user terminal device 30 side obtains the number of times each user has shaken the user terminal device 30 within each quota, and this number is used as information indicating the climax for each quota. An example in the case of sending to is shown. Further, the information indicating the excitement may not be the number of times that each user has swung the user terminal device 30. For example, the accumulated value of the acceleration detected by the acceleration sensor 36, or the accumulated value and each user may be the user terminal device. It is good also as both of the frequency | count of having shaken 30 etc.

  FIG. 5 shows an example of the participant excitement similarity table 12D indicating the similarity between pieces of information indicating the excitement of each user obtained by the excitement similarity determination unit 15 described above. In the participant excitement similarity table 12D, the degree of similarity between each user is indicated by the identification information [user_id] of the user, the identification information [target_id] of the target user corresponding to this identification, the target user, and the user's The similarity [score] is recorded.

  FIG. 6 shows an example of user information recorded in the above-described user information recording unit 14. As the user information, the above-described user identification information [user_id], the user name [user_name] of the user, and the mobile terminal unique ID of the user terminal device 30 used by the user are recorded.

  FIG. 7 shows an example of a table 22A indicating the relationship between users recorded in the member DB 22 of the member service providing unit 20 described above. In this table 22A, for example, user identification information [user_id] and other user identification information [friend_id] set as a “friend” of the user are recorded.

  The shared service providing unit 26 restricts, for example, the disclosure range of data stored in the shared DB 27 by a certain user to other users set as “friends” according to the information in the table 22A. Specifically, the shared service providing unit 26 refers to information in the table 22A when a certain user uses the shared service, and is shared by other users registered in the above-mentioned [friend_id]. Information about the data is acquired from the shared DB 27, and page description data such as HTML format or XML format including link information for the acquired data is created. The created page description data is supplied to the Web browser 42 of the user terminal device 40 (or the Web browser 32 of the user terminal device 30) via the HTTP server 21, the communication processing unit 11, and the network 1.

  In response to this, the user viewing the image displayed on the display unit 43 (or display unit 33) by the Web browser 42 (or Web browser 32) inputs an instruction using the input unit 44 (or input unit 34). Accordingly, it is possible to request the shared service providing unit 26 to transmit data shared by other users set as “friends”.

<Operation>
Next, the operation of the SNS providing system according to this embodiment will be described. In this SNS providing system, there are the following three processes that are executed independently as a whole.
(1) Event input In this process, information such as the event name, start time, end time, start time and end time of each quota is set in advance.
(2) Excitement input In this process, the dedicated application 37 transmits information indicating the excitement status to the excitement input unit 13, and the excitement input unit 13 records information indicating the excitement status in the event information recording unit 12.
(3) Similarity determination and user recommendation In this process, the excitement similarity determination unit 15 determines the similarity between information indicating the excitement status of each user recorded in the event information recording unit 12, and the similarity The similar user notification unit 16 notifies the user of a recommendation for a user whose value is higher than a predetermined value (for example, 0.85 as in an example described later).

<Event input>
In this SNS providing system, in the event information recording unit 12 in advance by an input from an input means (not shown) such as a keyboard provided in the server device 10 or an input from a data file including the contents of each item. Data of the event progress table 12A and the quota table 12B is set in advance.

<Energizing input>
FIG. 8 is an image diagram showing how the user terminal device 30 is used in the excitement input process. The user activates the dedicated application 37 in advance before participating in the event. The dedicated application 37 acquires the start time and end time of each quota for the event to participate from the excitement input unit 13. The user shakes the user terminal device 30 at an exciting timing while viewing the event.

  The dedicated application 37 obtains information indicating the user's excitement status (for example, the number of times the user terminal device 30 is shaken) from the detection output of the acceleration sensor 36 between the start time and end time of each quota. Further, for each quota, the dedicated application 37 transmits information indicating the number of times the user terminal device 30 is shaken within the quota and the mobile terminal unique ID of the user terminal device 30 to the climax input unit 13. .

  Upon receiving the information transmitted from the dedicated application 37, the excitement input unit 13 obtains user identification information [user_id] corresponding to the mobile terminal unique ID from the user information recording unit 14, and within the quota, the user terminal device 30 Is recorded in the above-described quota number table 12C in association with the number of times the number has been allocated. Thus, when the event ends, the number of times each user swings the user terminal device 30 within each quota of the event is recorded in the quota count table 12C.

<Similarity determination and user recommendation>
The excitement similarity determination unit 15 waits for the event to end based on the event progress table 12A. When the event ends, the process shown in FIG. 9 is executed to determine the similarity. First, the excitement similarity determination unit 15 extracts data recorded in the quota number table 12C for one person (S1), and the total number of times the user terminal device 30 is shaken in the quota number table 12C is a predetermined number. It is determined whether or not it is smaller than a value (for example, the number of minutes of the event) (S2).

  If the total number of times the user terminal device 30 is shaken is smaller than the predetermined value T, the user may not be a user who is interested or has similar sensibility even if the degree of similarity with other users is high. is there. For this reason, the excitement similarity determination part 15 is excluded from the similarity determination target in advance. For this reason, when the total number of times the user terminal device 30 is shaken is smaller than the predetermined value T, the swell similarity determination unit 15 does not determine the similarity with other users for the user, and the quota It is determined whether there is a next user in the frequency table 12C (S5). Thereby, it can prevent recommending the user who is not similar in the object of interest or sensitivity.

  Conversely, when the total number of times the user terminal device 30 has been shaken is equal to or greater than a predetermined value T, the swell similarity determination unit 15 determines that the user and all other data whose data is registered in the quota number table 12C. The degree of similarity with the other user is determined based on the cosine similarity (S3), and the obtained similarity [score] is associated with the identification information [target_id] of another target user and the participant excitement similarity table 12D (S4).

Here, the similarity based on the cosine similarity is specifically calculated as follows, for example.
Reference user data [q_1], [q_2], [q_3], and [q_4] recorded in the quota count table 12C are x1, x2, x3, and x4, and user data to be compared [q_1] and [q_2] , [Q_3], [q_4] are y1, y2, y3, y4,
Similarity [score] is calculated | required by following Formula.

  When the score obtained in this way is recorded in the participant excitement similarity table 12D in association with the identification information [target_id] of another target user as [score], the excitement similarity determination unit 15 performs the quota count table. It is determined whether or not the next user exists in 12C (S5). If the next user does not exist, the similarity determination is terminated. If the next user exists, the same processing (S1 to S5) is repeated for the next user. By such a process, as shown in FIG. 5 described above, the degree of similarity [score] between each user and the user and all other users is obtained in the participant excitement similarity table 12D.

<User recommendation>
When the excitement similarity determination unit 15 obtains the similarity between users, the similar user notification unit 16 performs a notification of recommending another user whose similarity is higher than a predetermined value (for example, 0.85). Specifically, for example, the similar user notification unit 16 generates a recommendation message including identification information [user_id] of another user recommended for the notification destination user, and sends the generated message to the message distribution control unit 24. By supplying.

  When such a message is supplied, the message delivery control unit 24 stores the message in an area assigned to the notification destination user in the M-BOX 25. When there is a transmission request from the Web browser 42 of the user terminal device 40 (or the Web browser 32 of the user terminal device 30) used by the notification destination user, this message is sent via the HTTP server 21, the network 1 or the like. It is supplied to the browser 42 (or Web browser 32) and displayed on the display unit 43 (or display unit 33).

  A user who has seen such a notification is recommended to the HTTP server 21 by operating the Web browser 42 (or the Web browser 32) when he / she wants to make the user recommended by the notification a “friend”. Request a change in relationship to a new user. This request includes the identification information [user_id] of the user recommended earlier and an instruction to make the user corresponding to the identification information “friend”. When such a request is supplied via the HTTP server 21, the relationship setting unit 28 identifies the user operating the Web browser 42 (or Web browser 32) in the table 22 </ b> A in the member DB 22. In the [friend_id] field corresponding to the information [user_id], the user identification information [user_id] included in the request is recorded. As a result, the newly registered user is treated as a “friend” when the shared service providing unit 26 provides the service.

<Effect>
In the SNS providing system of this embodiment, as described above, it is possible to recommend another user having a high degree of similarity of the information indicating the climax to the user, and the object of interest or sensitivity is easily similar. Users can be recommended. Moreover, since the information indicating the excitement status is obtained according to the detection output of the acceleration sensor 36 when participating in the event, it can be acquired without imposing a burden on the user.

  In the above-described similarity determination in S3 in FIG. 9, the cosine similarity is used, but the information indicating the user's excitement recorded in the quota table 12C (the user terminal device 30 is shaken). Any index other than the cosine similarity may be used as long as it is an index indicating the degree of similarity. The same effect as described above can be obtained even when the degree of swell similarity between users is determined using such an index.

  In the above description, the process of obtaining the similarity by obtaining the similarity according to the information (the number of times the user terminal device 30 has been shaken in the section) indicating the climax status aggregated for each section (quota). The load can be reduced. In the above description, the user to be recommended is determined according to the degree of similarity of the information indicating the climax status in the time obtained by dividing the time in the event into four times. If the information indicating the climax is acquired by further dividing the information, a more detailed similarity can be obtained.

  Alternatively, instead of the event, information indicating the excitement situation when the user views a moving image, audio, or the like reproduced by streaming is acquired in the same manner as described above, and the similarity is calculated based on the acquired information in the same manner as described above. You may make it ask.

  In the above description, the number of times the user terminal device 30 detected by the dedicated application 37 according to the output of the acceleration sensor 36 is used as the information indicating the excitement. An image instructing the user to press a predetermined key when the user swells is displayed on the display unit 33 of the terminal device 30, and the number of times the dedicated application 37 has pressed the key is displayed every predetermined time interval. It may be transmitted to the climax input unit 13. Further, in such an operation, the Web browser 42 of the user terminal device 40 displays a similar image, and the Web browser 42 transmits the number of times a predetermined key is pressed every predetermined time to the uplifting input unit 13. You may make it do.

<Modification>
Next, a modified example of the SNS providing system of this embodiment will be described. The SNS providing system according to this modification has a configuration similar to that of FIG. In the SNS providing system according to this modification, the event progress table 12A is not provided, and information indicating the user's excitement status is acquired at regular time intervals, and within a predetermined section (for example, four sections) obtained by dividing the time. The similarity of information indicating the climax is obtained.

  In this modification, the dedicated application 37 counts the number of times the user terminal device 30 is shaken according to the output of the acceleration sensor 36, and within a predetermined time [for example, every minute] The number of times of shaking is obtained, and information indicating the number of times (information indicating the rising status) and the mobile terminal unique ID of the user terminal device 30 are transmitted to the rising input unit 13.

  The excitement input unit 13 receives the information transmitted from the dedicated application 37 and holds the number of times for each portable terminal unique ID. Thereafter, the excitement input unit 13 indicates the start time and the end time of a predetermined section (for example, four sections every 5 minutes) at a certain time (for example, 20 minutes). A quota table 12B having the same configuration as in FIG. Furthermore, the excitement input unit 13 sums up the number of times held for each mobile terminal unique ID as described above for each section based on the quota table 12B, and the quota number table having the same data configuration as described above. Record in 12C.

  Similar to the above-described operation, the excitement similarity determination unit 15 obtains the similarity between the users from the data recorded in the quota table 12C, and the similar user notification unit 16 determines that the similarity is greater than or equal to a predetermined value. Notification to recommend users.

  By the operation as described above, in addition to the same effects as described above, it is not necessary to prepare the event progress table 12A in advance, and the workload of the administrator of the SNS providing system can be reduced. Further, in the operation as described above, the dedicated application 37 only transmits information or the like according to the number of times the user terminal device 30 is shaken according to the output of the acceleration sensor 36 at a predetermined time to the climax input unit 13. In this case, since it is not necessary to perform aggregation for each quota, the processing load on the user terminal device 30 side can be reduced.
