4 is a time series diagram illustrating a method of providing recommended music according to an embodiment of the present invention.

Hereinafter, a system and method for providing recommended music at the same time according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4 together.

First, according to an embodiment of the present invention, the time section determining unit 320 receives a search word and determines whether it is a recommended music search word in the same time zone, and determines a search word reception time in the case of a recommended music search word in the same time zone.

Many music services provide music streaming or download services. The user can directly search for and select a desired sound source to listen to music, but may listen to music by referring to a list of recommended sound sources provided by the sound source service. For example, the recommended sound source list provided by the sound source service may be a list of the most played sound sources in real time or by period (daily, weekly, monthly, etc.). Alternatively, the recommended sound source list may be a list of sound sources directly selected by a recommender or a list of sound sources of a specific category. That is, the recommended sound source list may be generated in various ways according to the sound source determination method.

As described above, the recommended sound source list may be a list played by different users for each set time unit. At this time, the unit of time may be real-time, daily, weekly, or monthly. For example, the weekly popular list may be a sound source list in which sound sources from the 1st to the 100th are arranged in the order of the most played in the week. Alternatively, the real-time popular list may be a list in which sound sources from the 1st to the 100th most played in real time are sorted. However, in the list of recommended sound sources for each time unit as described above, in general, the daily unit is the minimum unit, and real-time only provides the most listened sound sources in real time. Accordingly, it is not possible to provide a song that the user listens particularly frequently in a specific time period, for example, in the rush hour from 8:00 to 10:00 as a recommended sound source. In addition, in the list of recommended music sources for real-time, daily and weekly, it was common for many songs to overlap each other.

Accordingly, in an embodiment of the present invention, a system for providing recommended music for the same time period is provided, wherein a sound source that other users frequently listen to at a time requested by the user is provided as a recommended sound source, but the recommended sound source for each time period does not overlap. . That is, according to the present invention, it is possible to provide music that other users particularly listen to during a corresponding time period, not a general real-time popularity chart, as recommended music.

First, the request receiving unit 310 receives a search word and determines whether a request for recommended music is requested at the same time, and determines a request time when the request is for the recommended music at the same time. In more detail, the same-time recommended music request is a request to receive a sound source frequently heard by other users as a recommended sound source in a time period belonging to the time at which the user makes the request. According to an embodiment of the present invention, a user inputs a search word corresponding to a request for recommended music at the same time using the user terminal 110, 120, 130, 140, or recommends music at the same time using the user terminal 150 You can enter the utterance corresponding to the request.

According to an embodiment of the present invention, the request time may be a time when a user's request is received. Alternatively, according to another embodiment, the request time may be a time set by the user. For example, when the user's request is'recommended music for this time zone', the time at which the request is received is the request time, but when the user's request is '9 am recommended music', 9 am may be determined as the request time.

5 illustrates a user request and result according to an embodiment of the present invention.

Referring to the example of FIG. 5, the user may input "popular music in the current time" as a search word in the user terminal 110, and the request receiving unit 310 analyzes the search word received from the user terminal 110, It is determined that it corresponds to the request for recommended music at the same time. Alternatively, as another example, when the user utters "Play a good song for the time zone" on the user terminal 150, the request receiving unit 310 analyzes the utterance semantic and the user's utterance is recommended music in the same time zone. It can be determined that it corresponds to the request.

Upon receiving a user request as illustrated in FIG. 5, the same-time recommended music system according to an embodiment of the present invention may play recommended music between 6 pm and 8 pm. Hereinafter, a method of determining recommended music for the same time period will be described in more detail.

Next, the time section determination unit 320 classifies the time section and determines a recommended time section to which the requested time belongs. At this time, the time section refers to each time section in which a list of recommended music for the same time period is made. According to an embodiment of the present invention, the time interval may be a time interval of 2 hours by dividing 24 hours a day into 12 intervals. For example, the first time interval may be 00:00 to 02:00, and the second time interval may be 02:00 to 04:00. In one embodiment of the present invention, the user may utter "Play a good song for the time zone" at 18:30, and in this case, the request time is 18:30 as described above. In the above example, when 24 hours a day is divided into 2 hour intervals, 18:30 belongs to the tenth time interval, and thus the recommended time interval may be determined as the tenth time interval. However, it is not necessarily limited to the above-described example, and the time period of the present invention may be set at 3 hour intervals or different intervals (eg, dawn time, work time, evening time, etc.).

Next, the recommended sound source determination unit 330 determines recommended sound source tracks corresponding to the recommended time interval based on the number of reproductions of sound source tracks for each time interval. In more detail, the recommended sound source determination unit 330 maps the sound sources in the order of the highest number of playbacks in consideration of the number of playbacks of sound source tracks for each time period, but does not exceed a specific value for the ratio of sound sources included in the popularity chart for each time period. While doing so, the sound sources are mapped so that there are no sound sources that overlap with other time intervals.

In more detail, the recommended sound source determination unit 330 may include a total reproduction number determination unit 331, a section alignment unit 332, a track mapping unit 333, a duplicate removal unit 334, and a list determination unit 335. have.

First, the total number of playbacks determining unit 331 determines the total number of playbacks for each time section. The total number of playbacks per time section is the number of all sound sources played in a corresponding time section within a preset time unit. In this case, the total number of playbacks determining unit 331 may determine the total number of playbacks per time section on a daily basis. For example, if today is April 16, you can determine the total number of playbacks for each time section on April 15. However, it is not necessarily limited to the present embodiment, and the unit for determining the total number of reproductions may be variously determined in units of 24 hours or more. For example, when the preset unit is one week, a value obtained by summing the number of sound sources reproduced in a corresponding time section for a week may be the total number of reproductions.

6 illustrates the number of reproductions per time section according to an embodiment of the present invention.

As can be seen in FIG. 6, the first section is from 00:00 to 02:00, and the number of playbacks is 8011 times. In an embodiment of the present invention, 8011 times may mean the total number of playbacks of sound sources reproduced in a corresponding time interval on a working day. In addition, the second section may be 02:00 to 04:00, and the total number of times of playback of sound sources reproduced in the corresponding time section of the last day may be 12,491 times.

Next, the section sorting unit 332 determines the time zone ranking by arranging the time sections in the order of the large number of total reproductions. In the embodiment of FIG. 6, the time zone with the highest total number of playbacks based on the total number of playbacks is the 11th section of 20:00-22:00, and thus the 11th section is ranked first in the time slot. Based on the determined time zone ranking, the track mapping unit 333, the redundancy removing unit 334, and the list determining unit 335, which will be described later, may determine recommended sound source tracks for each time section in the order in which the time slot ranking is high. For example, it is possible to first determine the recommended sound sources ranked first, then determine the recommended sound sources ranked second, and sequentially determine the recommended sound sources of the remaining ranking.

7 shows a ranking of time zones and a ratio of including a popularity chart for each time zone according to an embodiment of the present invention.

First, referring to FIG. 7, in the time section column, each time section is arranged based on the total number of reproductions. In other words, it can be seen that the 11th section (20:00-22:00) with the highest total number of playbacks is ranked first in the time zone ranking, and the fourth section (08:00-10:00) with the second highest number of playbacks is the second in the time zone ranking. .

Next, the track mapping unit 333 arranges and maps sound sources in the order of the number of reproductions in each time section. That is, the track mapping unit 333 maps the tracks in the order of the tracks (sound sources) having the highest ranking based on the number of playbacks for each corresponding time section. For example, from midnight to 2:00 am, 100 songs of sound sources may be mapped to the first section (00:00 to 02:00) in the order of the highest number of playbacks. Referring to FIG. 8 to be described later, the track that was played the most in the 11th time section (20:00-22:00) is the track number with the number of played 94234 times is 2019241, and the track ranked first in the track ranking of the 11th time section. Becomes. In this way, sound sources ranging from 1st to 100th in the track ranking based on the number of reproductions in the 11th time section can be mapped to the 11th time section.

In this case, the number of sound sources mapped for each time interval may be equal to or greater than the number of recommended sound sources for each final time interval (the number of sound sources included in the recommended sound source list). For example, if it is finally desired to select 100 recommended sound sources for each time section, the track mapping unit 333 maps more than 100 songs to each time section, or does not limit the number of songs to be mapped. May not. This is to preliminarily map many sound sources because sound sources included in the popularity chart are removed in a step to be described later, or sound sources overlapping with sound sources in a time period having a high ranking are removed. In the examples of the inventions of FIGS. 6 to 10 described below, it is assumed that the number of recommended sound sources for each time section finally provided is 100 songs.

Next, the duplicate removal unit 334 removes a sound source that overlaps with a popularity chart that exceeds the popularity chart ratio for each time period, or removes a sound source that overlaps with a sound source in a time period whose time slot ranking precedes it. According to an embodiment of the present invention, even after a sound source mapped by the redundancy removal unit 334 is removed, a sound source having a sub-order number of playbacks is additionally mapped so that the number of all sound sources mapped for each time section is the same. Hereinafter, for convenience of explanation, the redundancy removal unit 334 removing sound sources that overlap with the mapped popularity chart by exceeding the popularity chart ratio for each time section is expressed as popular chart redundant sound source removal, and the redundancy removal unit ( 334) can be expressed as the removal of duplicate sound sources in the pre-ranking time zone when the sound source overlapping with the sound source in the time interval preceding the time zone ranking is removed.

More specifically, a configuration in which the duplicate removal unit 334 removes duplicate sound sources from popular charts will be described. According to an embodiment of the present invention, the duplicate removal unit 334 may belong to a corresponding time interval based on a ratio of the total number of reproductions in a corresponding time interval to the sum of the total number of reproductions in all time intervals (mid-day) for each time interval. Determines the percentage of tracks in the popular chart. At this time, for convenience of explanation, the ratio of the tracks belonging to the popularity chart that may belong to the corresponding time section is referred to as the popularity chart ratio. According to an embodiment of the present invention, the duplicate removal unit 334 determines a popularity chart ratio, and removes a sound source having a low track ranking mapped because the popularity chart ratio is exceeded from the mapped sound source list.

In more detail, if the total number of replays throughout the day is 1,000,000 times and the total number of replays in a specific time section is 1000,000 times, the popularity chart ratio, which is the ratio of the total number of replays in the specific time section, is 10%. In this case, according to an embodiment of the present invention, the ratio of the sound sources overlapping with the sound sources of the popular chart among the recommended sound sources of the specific time interval cannot exceed 10%. That is, in an embodiment of the present invention, when the number of recommended sound sources for each time section is set to 100, among the recommended sound sources of the specific section, songs overlapping with the sound sources of the popularity chart cannot exceed 10 songs. If more than 10 songs are mapped, the 11th overlapping sound source is removed from the recommended sound source list based on the number of playbacks.

In one embodiment of the present invention, a popularity chart is a chart provided by a sound source service, and is a chart providing a preset number of sound sources in the order of listening to many users by time unit. For example, the popularity chart may include a real-time popularity chart, a daily popularity chart, a weekly popularity chart, or a weekly popularity chart. In this case, the number of songs in the popularity chart of the present invention may be the same as the number of sound sources in the recommended sound source list for each time section finally provided. For example, if the number of sound sources in the recommended sound source list for each time section of the present invention is 100, the number of sound sources belonging to the popularity chart of the present invention may be set to 100. For example, the popularity chart according to an embodiment of the present invention is a daily chart, and may be a chart in which 100 songs are selected in the order of the most played sound sources yesterday.

According to an embodiment of the present invention, it is possible to adjust the mapped sound source for each time interval so that the sound source belonging to the popularity chart for each time interval does not exceed a specific ratio. This is to give differentiation from general popularity charts by not including songs that are popular in all time periods in more than a certain ratio, taking into account that the object of the present invention is to provide a recommended sound source specifically for a corresponding time period. to be. In addition, as described later, since the present invention starts mapping sound sources from a time interval with a high time ranking, and removes sound sources belonging to a time interval of a higher rank when mapping a sound source in a time interval with a low ranking in the time zone, This is to prevent the sound source of the popular chart from being excessively focused on.

Continuing to describe FIG. 7, the total number of reproductions in a corresponding time section is shown for each time slot ranking. For example, the total number of playbacks in the 11th time section (20:00-22:00), which is ranked first in the time zone, is 102381 times, which is 514187 times per day (the sum of the total number of playbacks in all time sections in FIG. 6) It is equivalent to 20% of Accordingly, the sound source of the recommended sound source list of the eleventh time section cannot overlap with the popular chart and the sound source more than 20 songs. In the same way, the sound source of the recommended sound source list of the fifth time section (08:00-10:00), which is ranked second in the time zone, may overlap with the sound source of the popular chart by 16 or more songs.

8 is an example of adjusting a mapped sound source in consideration of a popularity chart according to an embodiment of the present invention.

FIG. 8 shows sound sources mapped to an eleventh time section, which is ranked first in a time zone, following the example of FIGS. 6 and 7. As described above, the track mapping unit 333 may map the sound sources to the corresponding time interval in the order of the most played sound sources for each corresponding time interval (in the order of the highest track ranking). In addition, the duplicate removal unit 334 determines whether each track overlaps with the popularity chart. Referring to FIG. 8, it can be seen that all tracks above the track rankings 1, 2, 4, 7, 8, and 10 of the 11th section are included in the popularity chart.

The redundancy removal unit 334 removes from the mapped sound source list the sound sources of the sub-ranked ranking that are mapped beyond the popularity chart ratio among the mapped songs. That is, in the embodiment of FIG. 8, since the popularity chart ratio is 20%, the popularity chart redundant songs of the lower ranking ranking are removed from the mapped list so that only 20 songs overlap with the popularity chart. Since the mapped sound source corresponding to each time section must be 100 songs even after the overlapping songs on the popular chart are removed, a sound source with a lower order of reproduction may be additionally mapped.

Next, a description will be given of removing duplicate sound sources during the pre-ranking time by the duplicate removal unit 334. The duplicate removal unit 334 may perform a song overlapping with a song mapped to a time interval of the previous ranking for each time interval. That is, the redundancy removal unit 334 removes songs in which the time zone ranking overlaps with the previous time interval so that there are no overlapping sound sources for each time interval. After redundant songs are removed, another sound source with a subordinate number of playbacks is additionally mapped so that the number of sound sources mapped to the corresponding time interval maintains a set value. According to an embodiment of the present invention, additionally mapped songs should not overlap with the previous time section, and finally, the mapped sound sources for all time sections should not overlap with each other.

In an embodiment of the present invention, the operations of the deduplication removing unit 334 described above may be performed in the order of time zone ranking and sequentially for each time interval. In other words, after removing the overlapping sound sources on the popular chart that exceeds the popularity chart ratio for the sound sources mapped to the time zone ranking #1 in the time zone (there is no need to remove duplicate sound sources in the pre-ranking time zone) For the sound sources mapped to the great person time period, the ranking redundant sound sources in the pre-ranking time zone (time zone ranking 1st place) and the popular chart redundant sound sources are removed. Next, with respect to the sound sources mapped to the time section, which is ranked 3rd in the time zone, ranking duplicate sound sources in the pre-ranking time zone (time zone ranking 1st and 2nd place) and the popularity chart overlapping sound source are removed. In this way, duplicate songs are removed up to the 12th place in the time zone ranking, so that songs mapped to all time zones do not overlap each other.

9 is for explaining the removal of duplicate songs according to an embodiment of the present invention.

9 is a continuation of the embodiments of FIGS. 6 to 8, and when a sound source is mapped to an 11th time section above the time zone ranking as shown in FIG. 8, the fifth time section (08:00- 10:00), a configuration for removing duplicate sound sources among sound sources mapped to) is disclosed. First, the duplicate removal unit 334 first removes duplicate sound sources during the pre-ranking time. Since the pre-ranking time period is the 11th time period that is ranked first, the sound source overlapping with the sound source mapped to the 11th time period is removed from the fifth time period. In more detail, since the track number 419138 overlaps with the sound source of the eleventh time section, it may be removed. Likewise, since the track number 2914801 is also overlapped with the sound source of the eleventh time period, it may be removed. In addition, the duplicate removal unit 334 removes a sound source with a track ranking of 17th or less among the popular chart redundant tracks when the ratio of the popular chart sound source exceeds 16% even after removing the duplicate sound source during the pre-ranking time. As illustrated in FIG. 9, a mapped sound source may be added based on the number of reproductions so that 100 sound sources mapped to the fifth time period are maintained even after redundant sound sources are removed.

Next, the list determination unit 335 finally determines a list of recommended sound source tracks for each time section. According to an embodiment of the present invention, the list determination unit 335 may determine a list of recommended sound source tracks for each time section at midnight every day. That is, at midnight every day, a list of recommended sound source tracks for each time section may be determined based on the number of playbacks of sound source tracks played that day.

10 illustrates a list of recommended sound source tracks for each time section according to an embodiment of the present invention.

Referring to FIG. 10, track numbers of recommended tracks determined from the first to the twelfth time interval are shown. As can be seen from FIG. 10, the number of recommended tracks determined for each time section is 100, and it can be seen that the number of songs included in the daily chart does not exceed the daily chart ratio.

Next, the sound source providing unit 340 extracts and provides recommended sound source tracks corresponding to the recommended time interval according to the user's request. The sound source providing unit may extract recommended sound source tracks according to a user's request, and provide a song of a recommended sound source list in a recommended time interval in consideration of a ranking based on the number of playbacks. Alternatively, the sound source providing unit 340 may randomly select a track from a list of recommended sound source tracks corresponding to the recommended time interval requested by the user and provide it to the user. That is, the list of recommended sound source tracks for each time section may have a track ranking set based on the number of playbacks, but the sound source providing unit 340 may randomly provide sound sources included in the list to the user terminal to be played.
