Evaluation timing coefficient calculation unit 112 calculates an evaluation time factor T _i based on the timing of the performance evaluation by the performance evaluation section 102 is performed. For example, based on a predetermined relationship as shown in FIG. 6, the evaluation is performed based on the difference between the current month (current month) and the month (current month−n) in which the performance evaluation unit 102 performed performance evaluation. The timing coefficient T _i is derived. Also, evaluation results that are older than the month at that time by a predetermined period, for example, 20 months or more, may be uniformly set to T _i = 0. Such evaluation period coefficients T _i, which is calculated in the in the performance evaluation results of the performance evaluation unit 102, which play evaluation by the performance evaluation section 102 reflects the timing ie temporal opening has been performed, The smaller the time difference, the higher the weight is reflected in the performance evaluation result of each user. That is, in other words, the evaluation time coefficient calculation unit 112 relates to the statistics by the performance evaluation result statistics unit 106 in terms of the evaluation result by the performance evaluation unit 102 between the time point when the performance evaluation is performed and the current time. This is a calculation for performing correction to reflect a wide opening.

The store visit frequency coefficient calculating unit 114 calculates the store visit frequency coefficient F _f based on the visit frequency of the user corresponding to the performance evaluation by the performance evaluation unit 102. For example, based on a predetermined relationship as shown in FIG. 7, the store visit frequency coefficient F is based on the store visit history (store visit count W) to the store 12 where the karaoke apparatus 16 is installed, which is read from the SNS database 84. _{Derives f} . For users with extremely low frequency of visits (for example, users with W <3), F _f = 0 may be set uniformly. Furthermore, with such a low frequency of visits, the overall singing ability will be reduced. If not, the singing ability SA itself may be set to zero. The store visit frequency coefficient F _f calculated in this manner is obtained by adding the number of visits W in the past of the user corresponding to the performance evaluation to the performance evaluation result by the performance evaluation means 102. It is determined that the higher bonus points, the higher bonus points are added to the performance evaluation results of each user. That is, in other words, the store visit frequency coefficient calculating unit 114 reflects the visit frequency of the user corresponding to the performance evaluation in the evaluation result by the performance evaluation unit 102 regarding the statistics by the performance evaluation result statistics unit 106. A calculation for performing correction is performed.

The total performance number coefficient calculating means 116 calculates a total performance number coefficient N _f based on the total performance number N of the user corresponding to the performance evaluation by the performance evaluation means 102. For example, based on a predetermined relationship shown in FIG. 8, based on the total number N of performances that the user performed using the karaoke device 16 and evaluated performances, read from the SNS database 84. The total performance frequency coefficient N _f is derived. In addition, N _f = 0 may be set uniformly for a user whose total performance number N is extremely small (for example, a user who is <2), and further, the overall singing ability is not achieved with one or two songs. The singing ability SA itself may be set to 0 uniformly. Note that the total number N of performances may be limited within a predetermined period from that time, for example, within the past five years. The total performance number coefficient N _f calculated in this way is obtained by adding the total number of performances N in the past of the user corresponding to the performance evaluation to the performance evaluation result by the performance evaluation means 102. It is determined that as the number of performances N increases, higher bonus points are added to the performance evaluation results of each user. In other words, the total performance number coefficient calculating means 116, in other words, regarding the statistics by the performance evaluation result statistics means 106, the evaluation result by the performance evaluation means 102 is added to the total performance number of the user corresponding to the performance evaluation. A calculation for correcting the reflection is performed.
