  The above-described conventional technology specifies music suitable for each user based on information obtained by collecting the scoring results of a plurality of users. However, it is not taken into account how actively the score ranking results are played in the music that is suitable for the user. For this reason, in the above-described conventional technology, it has not been possible to fulfill the desire to sing songs that are actively ranked among users nationwide.

  The present invention has been made to solve the above problems. The purpose is to provide a technique for proposing music to the user based on the degree of activity of changing the rank in the scoring ranking obtained by summarizing the scoring results of a plurality of users.

  An information processing apparatus according to a first aspect includes a storage unit, a first determination unit, and a transmission unit. The storage means is associated with each of the plurality of pieces of music identification information, one or a plurality of scoring information representing the scoring result when the music is sung, date / time information representing the date and time when each scoring information was registered, and As for the scoring information, the ranking information indicating the ranking in one or a plurality of scoring information is stored. The first determining means includes, for a plurality of pieces of music identification information stored in the storage means, pieces of music identification information indicating characteristics that have a short elapsed time from the date and time associated with the high-ranking scoring information to the present time. A predetermined number is determined from the identification information. The transmitting means transmits the predetermined number of pieces of music identification information determined by the first determining means to the singing reservation apparatus as music recommending singing.

  According to the first aspect of the present invention, a song having a new date and time when a high-ranking scoring result is registered can be transmitted to the singing reservation device as a song that recommends singing. In the scoring ranking, that the date and time when the scoring result of higher ranking is registered is new indicates that the switching of the ranking of scoring results is active. For example, by transmitting the information of the music that is actively changing the ranking of the scoring results to the song reservation device and presenting the information, the user is actively competing in the ranking among the users nationwide. You can select a song after knowing whether it is in a state. Thereby, the user's request of wanting to sing a song whose ranks are actively competed among users nationwide can be fulfilled.

  The information processing apparatus according to claim 2 has the following characteristics. In other words, the first determination means is music identification information indicating a feature that has a short elapsed time from the date and time associated with the high-ranking scoring information to a plurality of music identification information, and is associated with the music identification information. A predetermined number of pieces of music identification information having a large total number of scoring information are determined from a plurality of pieces of music identification information.

  In addition, as a method for evaluating whether or not the battle for ranking is actively being performed, it is conceivable to configure as described in claim 3. In other words, for each of a plurality of pieces of music identification information stored in the storage unit, the information processing device has a frequency of change of rank as the elapsed time from the date and time associated with high-ranking scoring information to the present time is shorter. Second determining means for determining a parameter representing high is provided. And a 1st determination means determines the predetermined number of music identification information which satisfy | fills the conditions whose parameter is more than a predetermined reference | standard from several music identification information.

  The parameter here is an index that evaluates the frequency of the change of rank in the scoring ranking, reflecting the elapsed time. In the invention which concerns on Claim 3, a parameter is enlarged, so that the time when the scoring result matched with the high rank was registered in the scoring ranking for every music was new.

  The information processing apparatus according to claim 4 has the following characteristics. That is, for each of a plurality of pieces of music identification information, the second determination means sets the scoring information associated with the music identification information as the elapsed time from the date and time associated with the high-order scoring information to the current time is shorter. The parameter representing that the higher the total number of is, the higher the frequency of changing the order is determined.

  In the scoring ranking of singing results, in addition to the fact that the superiors are frequently replaced, it is considered that the more the number of participants, the more active the battle for ranking. Therefore, by determining the music that recommends singing in consideration of the total number of scoring results (that is, the number of participants), it is possible to provide information according to the actual situation.

  In addition, as a specific calculation method of the parameter indicating the frequency of the change of the order, it can be considered as described in claim 5. That is, for each of a plurality of pieces of music identification information, the second determining means calculates the product of the reciprocal of the rank represented by the rank information and the reciprocal of the elapsed time from the date and time associated with the rank information to the present time. As a parameter, a value obtained by summing all the rank information associated with the music identification information is determined. By doing in this way, the parameter which considered the ranking of ranking ranking, elapsed time, and the number of participants can be calculated.

  By the way, for example, when collecting and ranking singing scoring results over a wide range of nationwide scales, it is considered that singing scoring results are supplied from all over the country as needed. Therefore, it is preferable to configure as described in claim 6. That is, the second determination unit periodically re-determines the parameter for each of the plurality of pieces of music identification information. The first determination unit re-determines music identification information that satisfies a condition that the parameter is equal to or greater than a predetermined reference, based on the parameter re-determined by the second determination unit. And a transmission means transmits the music identification information re-determined by the 1st determination means to a song reservation apparatus as a music which recommends a song. By doing in this way, based on the scoring result acquired at any time, the music based on the parameter reflecting the latest situation can be presented.

  In addition, the invention which concerns on Claim 1 is implement | achieved as a karaoke system (Claim 7) which has a server apparatus provided with the function as the above-mentioned information processing apparatus, and the song reservation apparatus which receives music identification information from this server apparatus. You can also. The singing reservation apparatus which comprises this karaoke system is provided with a presentation means and an execution means. The presenting means receives a predetermined number of pieces of music identification information from the server device, and presents the music represented by the received music identification information as music for which singing is recommended. The execution means executes a music reservation process for reserving and registering a music piece designated for music selection in accordance with information on a music piece recommended for singing presented by the presentation means. According to such a karaoke system, an effect similar to the above-described effect described in claim 1 can be obtained.

  Further, the invention according to claim 1 can be realized as a program executed in a computer or a storage medium for storing the program as described in claim 8.

Then, the control unit 21 of the karaoke apparatus 20 proceeds to A of FIG. 3 and performs performance processing, video processing, and scoring processing of the music that has been selected and reserved in S18.

[Description of ranking result generation processing]
A procedure of ranking result generation processing executed by the control unit 11 of the ranking totaling server 10 will be described with reference to the flowchart of FIG. This process is a process executed in S30 (B) of FIG.

  In S100, the control unit 11 receives scoring data (see FIG. 5A) from the karaoke apparatus 20. In S102, the control unit 11 searches the ranking aggregation database (see FIG. 2A) using the song numbers registered in the currently received scoring data, and corresponds to the same song number as the scoring data song number. Select the ranking summary data to be used. In S104, the control unit 11 determines whether or not ranking aggregate data corresponding to the search in S102 exists. If there is no corresponding ranking total data (S104: none), the control unit 11 proceeds to S106. In S106, the control unit 11 newly creates ranking aggregate data corresponding to the song number of the scoring data received this time.

  On the other hand, when the corresponding ranking aggregate data exists (S104: present), the control unit 11 proceeds to S108. In S <b> 108, the control unit 11 additionally registers the user ID and the score of the currently received scoring data in the new scoring result record, and additionally registers the current date and time in the date / time item for the currently selected ranking aggregation data. Moreover, the control part 11 adds 1 to the number of participants corresponding to the ranking total data selected this time. The information to be registered in the date / time item is any of the current date / time (that is, the date / time registered in the ranking data), the date / time when the karaoke device 20 was sung, and the date / time when the scoring result was calculated. May be.

  In the next S110, the control unit 11 sorts all the scoring result records in the ranking total data selected this time in the order of scores (descending order). The order sorted in the score order corresponds to the rank in the ranking aggregate data. In S112, using the user ID of the currently received scoring data, the control unit 11 searches for a scoring result record in the ranking summary data selected this time. In S114, the control unit 11 performs three scoring results including a scoring result record corresponding to the user ID of the scoring data received this time, and a scoring result record corresponding to the order before and after the scoring result order. The result is extracted from the ranking summary data selected this time.

  In S116, the user name, score, and rank corresponding to each scoring result record extracted in S114 are additionally registered in each item of the record relating to the ranking of each user in the ranking result data (see FIG. 5B). The user name additionally registered here is obtained by converting the user ID registered in each scoring result record extracted in S114 into a user name associated with the user ID. In S118, the control unit 11 transmits the ranking result data completed in S116 to the karaoke apparatus 20 that is the transmission source of the scoring data received this time. After S118, the control unit 11 ends this process.

[Description of ranking activity calculation processing]
A procedure of ranking activity calculation processing executed by the control unit 11 of the ranking totaling server 10 will be described with reference to the flowchart of FIG. This process is a process executed in S32 (C) of FIG.

  In S200 to S216, the control unit 11 sequentially performs a loop process for each ranking aggregation data using the total number of ranking aggregation data for each song registered in the ranking aggregation database (see FIG. 2A). .

  In S202, the control part 11 resets the value of the activity corresponding to the ranking total data selected this time in S200 out of all the cases to 0. In the next S204 to S212, the control unit 11 sequentially performs a loop process on each of the scoring result records for all the participants, with respect to the scoring result records for all the participants registered in the ranking total data selected this time. . In S206, the control unit 11 calculates the reciprocal rT of the elapsed time from the date and time registered in the scoring result record selected this time to the current date and time. This rT is calculated by the following equation (1).

rT = 1 / (current date-time) (1)
In next step S208, the control unit 11 calculates a reciprocal tR of the rank (score sorting order) corresponding to the currently selected scoring result record. This tR is calculated by the following equation (2).

tR = 1 / rank (2)
In next S210, the control unit 11 adds the product of rT and rR calculated in S206 and S208 to the current activity value. Here, the calculation is performed according to the following equation (3).

Activity + = rT × rR (3)
In S212, when an unprocessed scoring result record remains, the control unit 11 returns to S204 and processes the next scoring result record. On the other hand, when the calculation process is completed for the scoring result records for all the participants, the control unit 11 finishes the loop process and proceeds to S214. The calculation formula of the activity A calculated in the loop processing of S204 to S212 is as the following formula (4).

上記式（４）において、ｉは、ランキング集計データ内での順位（ソート順）である。ｊは、ランキング集計データの参加人数である。ｒＲｉは、ｉ番目の順位の逆数（ｒＲ）である。ｒＴｉは、ｉ番目の採点結果における経過時間の逆数（ｒＴ）である。この活性度の計算式によれば、ランキング集計データ内で上位順位の変動があってからの経過時間が短いほど、高い数値が出るようになっている。また、上位順位が変動せず、下位でしか順位変動が起こらない状態では、たとえ参加人数が多くても低い数値しか出ないようになっている。一方で、参加人数が少なくても、１位や２位の上位が頻繁に変動すると高い数値が出る。つまり、活性度の数値の高さは、その楽曲において順位争いがどの程度活発に行われているかを表している。

In the above formula (4), i is a rank (sort order) in the ranking aggregate data. j is the number of participants in the ranking summary data. rRi is the reciprocal (rR) of the i-th rank. rTi is the reciprocal of elapsed time (rT) in the i-th scoring result. According to this formula for calculating the degree of activity, a higher numerical value is obtained as the elapsed time after the change of the higher rank in the ranking aggregate data is shorter. In addition, in a state where the upper rank does not change and the rank change only occurs in the lower rank, only a low value is obtained even if the number of participants is large. On the other hand, even if the number of participants is small, if the 1st or 2nd place frequently fluctuates frequently, a high number will be obtained. That is, the high numerical value of the degree of activity represents how actively the battle for ranking is performed in the music.

  In the next S214, the control unit 11 stores the activity value calculated by the loop processing in S204 to S212 in the activity item in the currently selected ranking total data. In S216, if unprocessed ranking summary data remains, the control unit 11 returns to S200, selects the ranking summary data of the next song from the total number, and processes the ranking summary data of the selected next song. I do. When the calculation process is completed for the ranking total data for all the cases, the control unit 11 ends this process.

  Here, the activity calculated by the ranking activity calculation process will be described with reference to FIG. The example of FIG. 9 represents a specific calculation example of the activity for the three songs A, B, and C. As illustrated in FIG. 9, when the calculation results of song A and song B are compared, the number of participants is the same, but song B is newer in terms of the second update period. Therefore, the activity of the song B is higher. Comparing the calculation results of song A and song C, the update times of the first to third places are the same, but song C has a larger number of participants. Therefore, the activity of the song C is higher. Comparing the calculation results of the music B and the music C, the latest update order is that the music B is second and the music C is ninth. Therefore, the activity of the song B is higher. In other words, the degree of activity is such that the value increases when the upper part is replaced, the value does not increase even if the lower part is replaced, and the number of participants is reflected in the value of the activity level, but the influence degree is not large.

[Explanation of the recommended entry data generation process]
The procedure of the recommended entry data generation process executed by the control unit 11 of the ranking tabulation server 10 will be described with reference to the flowchart of FIG. This process is a process executed in S33 (D) of FIG.

  In S300, the control unit 11 sorts the ranking aggregation data for each music stored in the ranking aggregation database (see FIG. 2A) in the order of the activity values associated with each song. In the next steps S302 to S314, the control unit 11 sequentially performs a loop process for creating recommended jump data for each ranking totaled data for a predetermined number (four in the present embodiment) of ranking totaled data.

  In S <b> 304, the control unit 11 acquires one piece of ranking total data whose activity satisfies a predetermined criterion from among a plurality of ranking total data sorted in order of activity. In the present embodiment, it is assumed that high-ranking ranking aggregate data with a high degree of activity is acquired. Or you may make it acquire arbitrary ranking total data from the ranking total data whose activity value is more than a predetermined reference value.

  In S306, the control unit 11 registers the song number and the number of participants registered in the ranking total data acquired in S304 in the item for each song in the recommended jump-in data (see FIG. 5C). In the next S308, the control unit 11 acquires the user ID registered in the highest scoring result record in the ranking total data acquired in S304, converts it into a user name, and converts each song in the recommended entry data Register in the item. In S308, instead of describing the highest-level user name, for example, the user name registered in the most recently registered (new date and time) scoring result record is described, and an arbitrary user name is specified. May be described. In the next S310, the control unit 11 registers the score registered in the scoring result record corresponding to the user ID acquired in S308 in the item for each song in the recommended jump-in data.

  In S312, when the loop processing for the predetermined number of cases has not been completed, the control unit 11 returns to S302, executes S304, and the activity is determined from a plurality of ranking total data sorted in the order of activity. Get the next ranking summary data that satisfies. Processing is performed on the ranking summary data of the next song. On the other hand, when the predetermined number of loop processes are completed, the control unit 11 ends the loop process and proceeds to S314. In S314, the control unit 11 transmits the recommended jump-in data generated by the loop processing in S302 to S312 to the karaoke apparatus 20. After S314, the control unit 11 ends this process.

[effect]
The karaoke system 1 according to the embodiment has the following effects.
Based on the ranking activity calculated based on the ranking total data for each song, it is possible to determine a song for which participation is recommended and present it to the user. The degree of activity is an index representing the activity of changing the rank in the ranking total data for each music piece. By transmitting the information of the music whose scoring result ranking is actively switched to the karaoke device 20 and presenting it, the user is actively competing in the ranking of the presented music among users all over the country. You can select a song after knowing if it is in a state. Thereby, the user's request of wanting to sing a song whose ranks are actively competed among users nationwide can be fulfilled.

  The karaoke system 1 assumes the following ranking battle cycle. (1) Someone finds a song that is not popular and is easy to win, and sings to win first place. (2) As a result, the first rank in the ranking is updated, and the activity of the music is greatly increased. (3) As the degree of activity increases, the music piece is displayed on the jump-in participation GUI screen as a music piece for which jump-in participation is recommended. (4) Someone sings by being guided to the displayed jump-in participation GUI screen. (5) In the stage where there are few participants in the ranking, it is easy to take the first place. (6) A high activity state continues for a while due to frequent switching of higher ranks. (7) Eventually, the number of participants in the ranking will increase and it will be difficult to acquire the top rank. (8) The high ranking update is stagnant and the activity is low. (9) Due to the low activity, the music is not recommended for participation.

By repeating the cycles as described in (1) to (9) above, an active ranking battle between users occurs in various musical compositions, and the game performance in the nationwide scoring function is enhanced.
