Hereinafter, specific embodiments of a method and system for providing a soaring music chart will be described.

FIG. 3 is a block diagram showing an example of components that can be included in a processor of a server according to an embodiment of the present invention, and FIG. 4 is a block diagram illustrating that the server executes according to an embodiment of the present invention. It is the flowchart which showed the example of the possible method.

The server 150 according to the present embodiment plays a role of a platform that provides a music service to a plurality of electronic devices 110, 120, 130, 140 that are clients. The server 150 may provide a music service in conjunction with an application installed in the electronic device 110, 120, 130, 140. In particular, the present application is related to music services, and may target the recently released music and generate and provide a rapidly growing music chart.

As shown in FIG. 3, the processor 222 of the server 150 includes a music selection unit 310, a rank calculation unit 320, and a chart provision unit 330 as components for executing the music chart provision method shown in FIG. Good. Depending on the embodiment, components of processor 222 may optionally be included in or excluded from processor 222. Also, depending on the embodiment, the components of processor 222 may be separated or merged for representation of the functionality of processor 222.

The processor 222 and the components of the processor 222 may control the server 150 to execute steps S410 to S440 included in the music chart providing method of FIG. For example, the processor 222 and the components of the processor 222 may be implemented so as to execute an instruction by the code of the operating system included in the memory 221 and the code of the at least one program.

Here, the constituent elements of the processor 222 may be expressions of different functions of the processor 222 that are executed by the processor 222 according to an instruction provided by the program code recorded in the server 150. For example, the music selection unit 310 may be used as a functional expression of the processor 222 that controls the server 150 according to the above-described instruction so that the server 150 selects the music to be exposed on the chart.

At step S410, the processor 222 may read the necessary instructions from the memory 221 loaded with the instructions related to the control of the server 150. In this case, the read instructions may include instructions for controlling the processor 222 to perform steps S420 to S440 described below.

The soaring music chart according to the present invention may be realized by the algorithms S420 to S440 of the following procedure, and may be generated at a predetermined cycle (for example, once a day).

In step S420, the music selection unit 310 may select, from the music registered in the platform, the music released within the recent certain period of time as the aggregation target for the soaring music chart. For example, in the soaring music chart according to the present invention, music released in the last one month may be selected as a chart exposure target. If the music release date has passed a predetermined period of time, it may be excluded from the chart aggregation target, which can increase the opportunity for new artists to be exposed.

In step S430, the rank calculation unit 320 may calculate the rank of each music due to the rank change by totaling the rank change of the chart total period for each music selected as the chart total target. In other words, the rank calculation unit 320 may calculate the rank for each music based on the rank change between the previous counting period and the latest counting period. For example, when the chart tabulation period is one week (7 days), the ranking of the previous week and the ranking of this week may be compared for each music, and the musical ranking may be determined in the order in which the ranking change of this week is larger than that of the previous week.

The specific method of calculating the music rank is as follows.

FIG. 5 is a diagram showing an example of a process of calculating a music rank in one embodiment of the present invention.

Referring to FIG. 5, in step S501, the rank calculating unit 320 may add up the number of plays for each unit period within the counting period for each music to calculate the total number of plays within the counting period. For example, the rank calculation unit 320 may sum up the number of daily plays within the total period to calculate the total number of plays in the previous week (previous total period) and the total number of plays in this week (the latest total period).

At this time, the number of playbacks means the number of users who have played music, and is a method in which each user is counted only once per unit period (for example, one day) (the number of unique users (unique user). count)). Even if one user listens to the same music many times within a unit period, the number of plays is counted as 1. By intentionally increasing the number of plays for a particular artist's music, the top of the chart is displayed. It prevents fraudulent attempts to be ranked. In other words, even if the specific music is reproduced a plurality of times within a unit period, for example, one day, the number of reproductions of the corresponding music may be regarded as 1 and processed.

In the present embodiment, the number of times played by the user is used for ranking calculation, but the present invention is not limited to this, and not only the number of times played, but also all numbers that can be aggregated for music, such as the number of times downloaded It is natural that the consumption index can be applied.

In step S502, the rank calculation unit 320 may calculate, for each music, a previous rank, which is a rank based on the total playback count of the previous total period, and a latest rank, which is a rank based on the total playback count of the latest total period.

For each piece of music released within a certain period of time in recent years, the total number of playbacks of the corresponding music in the previous week and in the last week and the ranking thereof may be obtained.

In the present embodiment, the music ranking is determined by the dense ranking method. For example, when the second place is a tie, the first place->the second place->the second place->the third place->...・As in the case of the same value, overlapping ranks are given, and from the next rank, ranks are given in order regardless of the overlapping ranks.

The same ranking is given to music with the same number of plays, and 1 is added from the next ranking. By using the dense ranking method, it is possible to prevent sudden changes in the ranking of music with few plays. Even if the number of views is relatively small, the rank change is compared to expose the chart, so that even an artist who is not popular in general can increase the chances of exposing the chart.

If the music was released during the most recent aggregation period and there is no data for the previous aggregation period, the median value of the rankings may be used as the previous ranking. For example, if the chart has up to 500 positions, then an intermediate value of 250 may be used. By using the median rank value for music for which there is no previous aggregation period data, it is possible to provide all artists with fair chart exposure opportunities. In other words, it is possible to provide a chart that is not excessively biased even if the number of plays by a famous artist is large.

In step S503, the rank calculating unit 320 may compare the previous rank and the latest rank for each music, and calculate a sharp increase score according to the rank change amount.

The sharply rising score may be defined as in Expression (1).

Soaring points = (Previous rank-Recent rank)/Recent rank... (1)

Therefore, the rank calculating unit 320 determines the music rank for each of the music released within a certain period of time in recent years on the basis of a sharply rising score indicating a change in rank depending on the total number of plays in the previous counting period and the latest counting period. be able to.

FIG. 6 is a diagram showing another example of the process of calculating the music ranking in the embodiment of the present invention.

Referring to FIG. 6, in step S601, the rank calculating unit 320 may calculate the average number of playbacks for each unit period within the counting period for each music. For example, the rank calculation unit 320 calculates the average daily number of plays in the aggregation period, and calculates the average daily number of plays of the previous week (previous aggregation period) and the average number of daily plays of this week (latest aggregation period). You can do it. At this time, the number of reproductions may be totaled by a method in which each user is counted once a day.

In step S602, the rank calculator 320 may calculate, for each music, a previous rank based on the average number of plays of the previous counting period and a recent rank based on the average number of plays of the latest counting period. The music ranking is obtained by the dense ranking method. At this time, if the music has been released in the latest counting period and there is no data for the previous counting period, the intermediate value of the ranking may be used as the previous ranking.

In step S603, the rank calculating unit 320 may compare the previous rank and the latest rank for each music, and calculate a sharp increase score according to the rank change amount. At this time, the jump score may be defined as (previous rank-latest rank)/most recent rank.

Therefore, the rank calculation unit 320 determines the music rank for each of the music released within a certain period of recent time, based on the sharply rising score indicating the change in rank depending on the average number of plays of the previous counting period and the latest counting period. can do.

In the present embodiment, by using the average number of plays for each unit period, it is possible to perform a fair ranking calculation regardless of the music release date. When simply using the number of playbacks instead of the average number of playbacks, the older the release date of the music, the more the number of playbacks, and thus the exposure of recently released music is reduced.

Referring again to FIG. 4, in step S440, the chart providing unit 330 may provide a jumping music chart that reflects the rank of each music, for each of the music released in the recent certain period. The chart providing unit 330 may provide a music chart with a sudden rise in music ranking according to the sudden rise score calculated in step S503 or step S603.

The chart providing unit 330 provides a music chart in which the music ranking sharply rises due to a change in the rankings of the previous aggregation period and the recent aggregation period, so that the user can receive various latest music with a chart in which the music ranking dynamically changes in each cycle. Can be provided.

FIG. 7 is a diagram illustrating an example of a process of providing a music chart according to an exemplary embodiment of the present invention.

Referring to FIG. 7, in step S<b>701, the chart providing unit 330 corresponds to the filtering condition based on the sharply rising score calculated in step S<b>503 or step S<b>603 among the music released in the recent certain period. At least some music may be excluded from the chart.

As an example, when the music of the same artist exceeds the predetermined maximum number (for example, 2 songs) of the music released within a certain period of time in recent years, the chart providing unit 330 is in descending order of the score. You may leave the maximum number of music and remove the rest of the music from the chart. In other words, the chart providing unit 330 filters the music of the same artist so that only the maximum number of songs are exposed to the chart, thereby preventing fraud in which only a large number of music of popular artists monopolizes the chart. be able to.

Besides filtering by artist, filtering by album is also possible. That is, it is possible to filter so that only the maximum number of songs of the same album are exposed on the chart.

As another example, the chart providing unit 330 may exclude, from the charts, music belonging to a specific genre set as a filtering condition, out of the music released within a certain period of recent time.

In addition to filtering specific genres, it is also possible to filter some specific types of music such as MR (music recorded) and Inst (instrumental).

When at least one music is excluded from the chart by the filtering, the chart providing unit 330 may rearrange the ranking by the jump score for the remaining music according to the general ranking or the dense ranking method to provide the jump music chart.

Therefore, the chart providing unit 330 can prevent fraud in which many music of popular artists monopolize the chart excessively by filtering, and exclude music of a specific genre or type from the chart.

In step S<b>702, the chart providing unit 330 may divide the music released in the recent certain period into domestic music and overseas music, and provide the respective soaring music charts. The chart providing unit 330 may divide the music ranking according to the ranking change between the previous aggregation period and the recent aggregation period into domestic music and foreign music and may provide a soaring music chart, or may provide domestic music and foreign music. It is also possible to provide a soaring music chart according to the ranking of music according to the ranking change between the previous aggregation period and the recent aggregation period after dividing.

The chart providing unit 330 may provide a music chart whose popularity is rapidly increasing among the music released in a certain period in recent years. As an example, the chart providing unit 330 provides a soaring music chart corresponding to a user's request. As shown in FIG. 8, domestic music and foreign music are not divided into domestic music and foreign music. An overall ranking soaring music chart 800 may be provided including both, and in some cases, the soaring music chart 910 for domestic music and the soaring music chart for overseas music 920 may be selectively selected as shown in FIG. May be provided to

In addition to providing domestic music and overseas music by providing a soaring music chart, it is possible to provide the soaring music chart by classifying various themes such as genre and generation. At this time, one music may be included in a plurality of charts.

The chart providing unit 330 can uniformly expose the music of various artists by providing a music chart that rapidly increases according to the music ranking due to the ranking change of the previous aggregation period and the recent aggregation period, so that not only popular artists can be exposed. The music of new artists can be fairly exposed.

As described above, according to the embodiment of the present invention, by providing a soaring music chart using a change in rank between the previous aggregation period and the recent aggregation period for music released within a certain period in recent years. We can provide various and dynamic music charts. In addition, according to the embodiment of the present invention, the average number of plays per day is used to determine the ranking, and if there is no data for the previous aggregation period, the intermediate value of the ranking is used, so that music charts for all artists can be obtained. It can provide fair exposure opportunities. Further, according to the embodiment of the present invention, by determining the ranking by using the average number of played times per day, it is possible to provide a music chart of a fair ranking regardless of the music release date. The exposure opportunity of can be guaranteed.

The apparatus described above may be implemented by hardware components, software components, and/or a combination of hardware and software components.
