And can be done. On the other hand, when the rejection information is sent, the functions that the user can use for browsing the information on the personal Web page and viewing the performance information are limited.

[Evaluation process]
The evaluation process will be described with reference to the flowchart of FIG. In a state where the login process is executed and the evaluation of the performance information by the user is permitted, when the evaluation of the performance information is executed by a user operation, the evaluation process is started by the control unit 100. In this embodiment, the user's evaluation is a voting-type evaluation, and the performance information is evaluated by voting on the performance information that the user likes.

  In step S100, evaluator evaluation information is acquired. Specifically, the evaluator votes the performance information to be evaluated by operating the operation unit 103. The operation processing unit 102 receives operation information regarding the evaluator's evaluation sent from the operation unit 103, and sends an evaluation request to the control unit 100. Upon receiving the evaluation request, the control unit 100 generates evaluator evaluation information and moves the process to step S101.

  In step S101, an evaluation instruction is sent to the karaoke server apparatus 3. Specifically, the control unit 100 associates the evaluator evaluation information acquired in step S100, the evaluator's karaoke user identification information, and the performance identification information that the evaluator wants to evaluate, and evaluates the performance information. Is generated to instruct the karaoke server device 3. The generated evaluation instruction is sent from the evaluation device 1 to the karaoke server device 3. When the control unit 100 sends an evaluation instruction, the control unit 100 stops the process, and when receiving a completion notification from the control unit 300, starts the process of step S109. Moreover, the control part 300 of the server apparatus 3 for karaoke will perform the process of step S201, if an evaluation instruction | indication is received.

  In step S201, karaoke information is extracted. Specifically, the control unit 300 uses the evaluator's karaoke user identification information, which is evaluator information stored in the storage unit 301, and the music related information according to the karaoke user identification information and performance identification information included in the evaluation instruction. The music identification information of the music included in certain performance information and the creator's karaoke user identification information included in the music information of the music represented by the music identification information are read from the storage unit 301. The plurality of read identification information and the correspondence relationship between the identification information are stored in the storage unit 301 as karaoke information. If karaoke information is read from the memory | storage part 301, the process of the control part 300 will be moved to step S202.

  In step S202, it is determined whether the evaluator is using SNS. Specifically, control part 300 judges whether SNS user identification information is matched with evaluator's karaoke user identification information among karaoke information extracted in Step S201. In the karaoke information, when the SNS user identification information is associated with the evaluator's karaoke user information, the control unit 300 determines that the evaluator is using the SNS. Thereby, the control part 300 transfers a process to step S203 noting that the process of step S203 is YES. In the karaoke information, when the SNS user identification information is not associated with the evaluator's karaoke user identification information, the control unit 300 determines that the evaluator does not use the SNS. Thereby, the control part 300 transfers a process to step S207 noting that the process of step S203 is NO.

  In step S203, an SNS information extraction instruction is transmitted to the SNS server device 4. Specifically, the control unit 300 sends an instruction to extract the SNS information from the storage unit 401 of the SNS server device 4 to the control unit 400 of the SNS server device 4. The control unit 300 includes the SNS user identification information of the creator associated with the music identification information of the music associated with the performance identification information transmitted from the control unit 100 of the evaluation device 1 in step S201, and the SNS of the evaluator. In order to acquire SNS information related to the user identification information, an SNS information extraction instruction is sent to the control unit 400 of the SNS server device 4. That is, the control unit 300 extracts SNS user identification information associated with the evaluator and creator's karaoke user identification information from the karaoke information, and outputs an SNS information extraction instruction including the extracted SNS user identification information to the SNS server apparatus 4. To the control unit 400. When the SNS information extraction instruction is transmitted to the SNS server device 4, the control unit 300 stops the process, and when receiving the SNS information from the control unit 400, the control unit 300 starts the process of step S204. In addition, when receiving an SNS information extraction instruction, the control unit 400 starts the process of step S303.

  In step S303, SNS information is extracted. Specifically, in accordance with the SNS information extraction instruction sent from the control unit 300, the control unit 400 is associated with the SNS user identification information of the evaluator and the creator from a plurality of information stored in the storage unit 401. SNS information indicating the corresponding relationship is extracted. When the control unit 400 extracts the SNS information, the process proceeds to step S304.

  In step S304, the SNS information extracted in step S303 is transmitted to the karaoke server apparatus 3. Specifically, the control unit 400 sends the SNS information extracted in step S303 to the control unit 300. When the control unit 400 sends the SNS information to the control unit 300, the control unit 400 ends the process. In addition, when the control unit 300 receives the SNS information, the control unit 300 moves the process to step S204.

  In step S204, evaluator points are calculated. That is, the strength of the connection between the user and the music is calculated from the correspondence relationship indicated by the SNS information. Specifically, the control part 300 performs the matching process of SNS information and karaoke information memorize | stored in the memory | storage part 301, and the correspondence from an evaluator's SNS user identification information to an author's SNS user identification information Determine the state. The control part 300 adds the point defined according to the state of the correspondence of the information from an evaluator's SNS user identification information to an author's SNS user identification information to an evaluator point. The relationship between the evaluator and the creator can be divided into four states. When the calculation of the evaluation points from the first state to the fourth state in the SNS information is completed, the control unit 300 moves the process to step S205.

[First state]
The first state indicates the relationship between the evaluator and the creator when the evaluator and the creator are the same. The control unit 300 determines whether or not the evaluator and the creator are the same. The control unit 300 determines whether the evaluator's SNS user identification information is the same as any of the creator's SNS user identification information. When it is determined by the control unit 300 that they are the same, the control unit 300 adds 10 points to the evaluator points. When it is determined by the control unit 300 that they are not the same, the control unit 300 does not add points to the evaluator points. As a typical example of the first state, the evaluator X and the singer A are the same person, and the SNS user identification information of the evaluator X and the SNS user identification information of the singer A completely match.

[Second state]
The second state indicates the relationship between the evaluator and the creator when the following two conditions are satisfied. The first condition is determined by the control unit 300 that any SNS user identification information of the creator included in the SNS information is associated as a referenced flag of the SNS user identification information of a specific evaluator. It is a condition. The second condition is that the creator's SNS user identification information associated with the SNS user identification information of the specific evaluator is associated as the reference flag of the SNS user identification information of the specific evaluator. This condition is determined by the control unit 300. When the control unit 300 determines that the state is the second state, the control unit 300 determines the evaluator points for the evaluator's SNS user identification information and the creator's SNS user identification information that is determined to be the second state. Add 5 points. As a typical example of the second state, the SNS user identification information of the evaluator X is associated with the reference flag and the referenced flag of the SNS user identification information of the singer A shown in (A) and (B) of FIG. It is in a state. Alternatively, the SNS user identification information ID 101 of the evaluator X and the SNS user identification information ID 102 of the singer A shown in FIG. 3 are directly connected to each other by arrows.

[Third state]
The third state shows the relationship between the evaluator and the creator when the following two conditions are satisfied. The first condition is determined by the control unit 300 that any SNS user identification information of the creator included in the SNS information is associated as a referenced flag of the SNS user identification information of a specific evaluator. It is a condition. The second condition is that the creator's SNS user identification information associated with the SNS user identification information of the specific evaluator is associated with the reference flag of the SNS user identification information of the specific evaluator. This is a condition determined by the controller 300. If the control unit 300 determines that the state is the third state, the control unit 300 determines the evaluator points for the evaluator's SNS user identification information and the creator's SNS user identification information that is determined to be the third state. Add 3 points. As a typical example of the third state, the SNS user identification information of the evaluator X is associated with the reference flag of the SNS user identification information of the singer A, but the evaluator is associated with the referenced flag of the SNS user identification information of the singer A. This is a state in which X SNS user identification information is not associated.

[Fourth state]
The fourth state shows the relationship between the evaluator and the creator when the following two conditions are satisfied. The first condition is a condition in which the control unit 300 determines that any set information included in the SNS information is associated as a reference flag of the SNS user identification information of a specific evaluator. The second condition is determined by the control unit 300 that the set information associated with the reference flag of the SNS user identification information of the specific evaluator is associated with the reference flag of the creator's SNS user identification information. This is a condition. When it is determined by the control unit 300 that the state is the fourth state, the control unit 300 includes one set of information when the relationship between the evaluator's SNS user identification information and the creator's SNS user identification information is in the fourth state. 1 point is added to the evaluator points. As a typical example of the fourth state, an arrow is connected to the composer fan page identification information ID13 from the SNS user identification information ID101 of the evaluator X and the SNS user identification information ID104 of the composer shown in FIG. It is. Alternatively, the SNS user identification information ID 101 of the evaluator X and the SNS user identification information ID 104 of the composer are associated with the referenced flag of the composer fan page identification information ID13.

  In step S205, evaluation auxiliary information is calculated. Specifically, the control unit 300 generates auxiliary evaluation information indicating the number of votes to be added to the evaluator evaluation information according to the evaluation points. When the control unit 300 calculates the auxiliary evaluation information, the control unit 300 moves the process to step S206.

  In step S206, karaoke user information is updated. Specifically, the song identification information of the song that the evaluator wants to evaluate and the evaluation auxiliary information are associated with the karaoke user identification information of the evaluator. When the evaluator's karaoke user identification information, the music identification information of music A, and the evaluation auxiliary information are associated with each other, control unit 300 moves the process to step S207.

  In step S207, the evaluator evaluation information and the performance information are associated with each other. Specifically, the control unit 300 adds the evaluator evaluation information to the evaluation information previously associated with the performance information. When there is evaluation auxiliary information representing one or more votes at the time of adding the evaluator evaluation information, the control unit 300 adds the evaluation auxiliary information to the evaluator evaluation information, and the evaluator evaluation information added with the evaluation auxiliary information. Is added to the evaluation information. Further, the control unit 300 associates the information of the voting history with the evaluation information so that it can be understood when and who has voted how many votes.

  In step S208, the performance information display screen is updated. Specifically, the display for viewing the video represented by the performance information is updated in the evaluation apparatus 1 or the like. When the performance information display screen is updated, the control unit 300 moves the process to step S209.

  In step S209, a completion notification is sent to the control unit 100. Specifically, the control unit 300 sends a completion notification indicating that the evaluation process has been completed to the control unit 100. When the completion notification is sent to the control unit 100, the control unit 300 ends the process.

  In step S109, a completion notification is received. Specifically, when receiving the completion notification from the control unit 300, the control unit 100 notifies the user that the evaluation process has been completed. When the user is notified that the evaluation process has ended, the control unit 100 ends the process.
