  The present invention relates to a music search system, and more specifically, when a plurality of users having different ranks enjoy the karaoke by using the same karaoke performance apparatus at the same time, the musician and the other users The present invention relates to a music search system capable of selecting appropriate karaoke music so as not to cause a sense of incongruity.

  Karaoke facilities, such as a karaoke box, may be used by a plurality of users as members in order to establish relatives. At this time, not only users who are well-minded but also users who meet for the first time or users who have little chance to enjoy karaoke together may perform karaoke singing as members.

  If you are a member with a certain mind, knowing what kind of karaoke song will make you feel the atmosphere will be exciting, and even if you sing a karaoke song that does not fit the atmosphere a little, it is often acceptable. .

  However, if a user other than a well-minded user is a member or is a mixture of members, there is a possibility that he or she will be lost in the selection of karaoke music so as not to disturb the atmosphere of the place. In particular, when superiors and subordinates enjoy karaoke together, or when entertaining business partners, it is desirable that all members comfortably enjoy karaoke and deepen relatives by performing appropriate music selection.

  As described above, when a plurality of users gather to select music, there is disclosed a technique for presenting an index indicating the preference of another user for the designated music selection item (see Patent Document 1).

The greater the number of past simultaneous logins, the more often the user has enjoyed karaoke together, and the less the number of past simultaneous logins, the less often the user has enjoyed karaoke together, and the number of past simultaneous logins is "0 times". If so, it can be determined that they have never enjoyed karaoke together. At this time, in order to prioritize the treatment of the user as the number of past simultaneous logins is small, if the number of past simultaneous logins is small, the order is high, and if the number of past simultaneous logins is high, the order is low.

  When the order is determined, the function of the music piece coincidence degree determination means determines the presence or absence of the karaoke music with the item of the history information set corresponding to the order as an extraction item. That is, it is determined whether the karaoke song corresponding to the extraction item is present in the song candidate song list by user, and the degree of coincidence of the number of times of the presence is determined. Setting the extraction items of the history information corresponding to the order means, for example, determining the order in a plurality of stages, setting the number of extraction items more if the order is high, setting the extraction items less if the order is low . Here, for example, when the song history is an extraction item, the song history is compared with the song candidate song list by user, and it is determined whether or not there is a song that matches both and the number of times is a match degree Do.

  If the degree of coincidence is determined, the function of the music selection effectiveness calculation means is based on the weighting of the degree of coincidence set according to the order, the music selection effectiveness of each user for the music present in the song candidate song list by user. Calculate the degree. The weighting of the matching degree set according to the order means, for example, when the order is determined in a plurality of stages, the weighting for the matching degree is set large if the order is high, and the weighting for the matching degree is set if the order is low. It is to set small.

The reserved music management table 23a is a data table in which music IDs and user IDs of music selected by the user using the function of the music search means 12a are associated and arranged in the order of performance.

  The order determining means 27 is a program for determining the order between each user based on the number of times other users who are currently logged in together with the music selectr logged in simultaneously in the past. For example, if the number of simultaneous logins in the past is high, the number of times that the user enjoys karaoke together is high, and the order is determined to be low, as the need for priority treatment is low. On the other hand, if the number of simultaneous logins in the past is small, the number of times the user enjoys karaoke together is so small that it is highly necessary to give priority treatment, and the order is determined to be high. In particular, if the past number of simultaneous logins is “0 times”, it can be determined that the user is a first-person user who has never enjoyed karaoke together.

  There may be any number of rank divisions, but, for example, as shown in FIG. 3, there are three stages of “high”, “medium”, and “low” corresponding to the past number of simultaneous logins. Although the number of past simultaneous logins defined to determine the stage of each order can be set as appropriate, for example, if the number of past simultaneous logins is 3 or less, the order is set to “high” and the same time logins in the past are made. If the number of times is 4 to 7, the order is set to "middle", and if the number of past simultaneous logins is 8 or more, the order is set to "low". Also, instead of defining and determining the order based on the number of simultaneous logins in the past, the order may be determined according to the number of times of simultaneous logins in the past among users currently enjoying karaoke together. . In this case, the rank of the user with the least number of concurrent logins in the past is "high", the rank of the user with the largest number of concurrent logins in the past is "low", and the rank of the other users is "medium" Do.

<Matching degree determination means>
The music match degree determination means 28 uses the item of the history information set corresponding to the order as an extraction item, and determines whether or not the karaoke music corresponding to the extraction item exists in the song candidate song list 23b classified by user. It consists of a program for judging and judging the degree of coincidence of the frequency of existence. That is, in the music piece coincidence degree determination means 28, it is judged whether or not the karaoke music piece corresponding to the extraction item is present in the song candidate music list by user 23b, and the degree of coincidence of the number of times of existence is judged.

  For example, when the order is determined in three levels of “high”, “medium”, and “low”, extraction items of history information are set corresponding to each order. That is, as shown in FIG. 4, if the order is high, the number of extraction items is set large, and if the order is low, the extraction items are set small. Specifically, when the singing history is set as an extraction item, the music ID existing in the singing history is compared with the music ID existing in the user-specific song candidate music list 23b, and the existence of the coincident music ID exists Make the number of matches In the example shown in FIG. 4, when the order is "high", the song history, the music listening history, and the good song are extracted items, and when the order is "middle", the song history and the good song are extracted items. If the order is "low", the song history is taken as the extraction item. By setting the extraction item of the history information corresponding to the order in this manner, the extraction item increases as the order is higher, so that the degree of music coincidence also increases, and priority treatment can be performed.

<Selection of music selection effectiveness calculation means>
The music selection effectiveness calculation means 29 is a program for calculating the music selection effectiveness of each user for the music present in the user song candidate song list 23b based on the weighting of the coincidence level set according to the order. Become. Here, the weighting of the matching degree set according to the order is, for example, as shown in FIG. 4, when the order is determined in three stages of “high”, “medium”, and “low”. Set the weight for the matching degree in the order of "high", "medium" and "low". That is, if the rank is high, the weight is increased, and if the rank is low, the weight is decreased. In the example shown in FIG. 4, when the order is "high", the weighting is 1.5, when the order is "medium", the weighting is 1.0, and when the order is "low". , Weighting is 0.5. As shown in FIG. 5, the music selection effectiveness calculation means 29 calculates the music selection effectiveness of each user based on the weighting of the set coincidence level. In the example shown in FIG. 5, the music selection effectiveness of the user surrounded by a thick frame is the highest for each music.

  Specifically, the user A's score for the song "AA" is three times for the song history, one for the listening history, and one for the good song, and the total value "5" of these is weighted to "1.5 The result is 7.5 points. In this case, the singing history, listening history, and good music become extraction items for the user A whose rank is “high”, and the singing history and good music become extraction items for the user B whose rank is “middle”. Therefore, even if the raw points of the user A and the user B are the same, the weighting is different, so that the music selection effectiveness for the user A is the highest for the music “AA”.

  Similarly, the user B's score for the music "BC" is 2 times for the singing history and 5 times for the listening history, and the sum "7" of these is multiplied by the weighting "1.0" to obtain 7 points. Become. In addition, for the song "EE", no song history, listening history, and good song exist for any user, so it is not a target of song selection. As described above, the higher the order is, the more the number of tunes that hit (match) the other users because the number of population increases, and the weighting operation is performed. The effectiveness is high.

<Selection of music selection effectiveness notification control means>
