(Pairing processing unit)
The pairing processing unit 22a performs pairing between the user terminal and the karaoke device. A known method (see Japanese Patent Application Laid-Open No. 2013-114012, etc.) can be used for pairing the karaoke device and the user terminal.

For example, it is assumed that the terminal identification information and the device identification information of the karaoke device K are received from the transmission processing unit 14a of the user terminal M. In this case, the pairing processing unit 22a performs pairing between the user terminal M and the karaoke device K by associating the terminal identification information and the device identification information and registering them in the storage means 20.

(Extractor)
The extraction unit 22b is event schedule information indicating an event personally planned by the user from the schedule information in which the schedule of the user is registered, which is acquired from the user terminal owned by the user of the karaoke device. Moreover, the event schedule information included within the predetermined period is extracted.

In the event personally planned by the user, "location" information is registered. "Birthday" is an event that you always visit regardless of whether you have a personal plan or not, and "place" is not registered.

The predetermined period limits the range in which the event schedule information is extracted. The predetermined period is set in advance, for example, within 15 days from the current time (that is, when the schedule information is acquired), within 10 days before and after the current time, and the like.

Further, when the event schedule information cannot be extracted from the schedule information acquired from the user terminal, the extraction unit 22b may extract the event schedule information based on the search result acquired from the search system. The search system is an external server device or the like provided separately from the music recommendation system 1.

Here, it is assumed that the schedule information shown in FIG. 3 has been acquired as of July 6, 2019. In addition, "within 15 days from the present time" is set as a predetermined period, and the memory means 20 has a soccer team name "△△△", a baseball team name "●●●", as keywords corresponding to the event schedule information. It is assumed that the title of the movie "XXX" and "Hokkaido" indicating the location of the travel destination are stored.

First, the extraction unit 22b extracts the baseball team names “●●●” and “Hokkaido” whose schedule information matches the keyword stored in the storage means 20 as the event schedule information.

On the other hand, the schedule information regarding "movie" and "watching soccer game" does not match the keyword stored in the storage means 20. That is, the extraction unit 22b cannot extract the event schedule information.

In this case, the extraction unit 22b transmits the schedule information of "movie" and "watching soccer game" to the search system together with the date of each event. Specifically, the extraction unit 22b describes "content: movie, date and time: July 2, 2019 13: 00-, place: Shibuya Theater" and "content: watching soccer, date and time: 2019". July 16, 19: 00-, Location: Saitama Stadium "is sent to the search system.

The search system searches for reference information corresponding to the received schedule information. In this example, the search system has a movie title "XXX" which is reference information corresponding to "movie" as a search result, and a soccer team name "△△△" which is reference information corresponding to "watching soccer". Suppose you got. The search system transmits the search result to the server device S.

The extraction unit 22b can extract the movie title “XXX” and the soccer team name “△△△” as event schedule information based on the search results acquired from the search system.

Further, among the schedule information shown in FIG. 3, "birthday" is not extracted as event schedule information.

Next, the extraction unit 22b extracts the event schedule information included within the predetermined period from the extracted event schedule information.

As described above, the predetermined period is "within 15 days from the present time". Therefore, the extraction unit 22b is currently (of the extracted event schedule information, the movie title "XXX", the baseball team name "●●●", the soccer team name "△△△", and "Hokkaido". The baseball team name "●●●" and the soccer team name "△△△", which are event schedule information within the next 15 days from (July 6), are extracted.

The extraction unit 22b may extract the character string included in the predetermined period in advance, and extract the event schedule information depending on whether the extracted character string matches the keyword stored in the storage means 20. Good.

In addition, since the event schedule information is arbitrarily registered by the user, it does not always exactly match the stored keywords. For example, it is assumed that "△△△" is stored as a keyword as in the above example. In this case, if an exact match with the keyword is required, the extraction unit 22b cannot extract the event schedule information registered as "Saitama △△△".

Therefore, the extraction unit 22b may extract the event schedule information according to the degree of matching between the character string included in the schedule information and the keyword. For example, the extraction unit 22b can extract the character string as event schedule information when there is a word matching the keyword in the character string or when 80% or more of the common characters are included.

(Specific part)
The identification unit 22c identifies the related music corresponding to the extracted event schedule information.

The related music is a music corresponding to the event schedule information among the music that can be sung by the karaoke device. At least one related song is required. For example, when the event schedule information is the soccer team name "△△△", the related music is associated with a music that is often heard in the soccer field (for example, a team cheering song). Alternatively, when the event schedule information is the title of a specific concert or movie, the related music may be the music of the artist performing the concert or the music related to the movie being shown in the movie theater.

It is highly possible that the concerts held at the concert venue and the movies shown at the cinema will differ from day to day. Therefore, it is preferable that the related music corresponding to such an event is updated regularly. The server device S acquires information (artist name, movie name, etc.) about the concert or movie by accessing the search system. The server device S stores the music in the storage means 20 as a related music by associating the music corresponding to the acquired information about the concert or the movie from the music that can be played by the karaoke device.

FIG. 5 shows a table of related songs stored in the storage means 20. In FIG. 5, the keyword: soccer team name “△△△” (schedule information “watching soccer”) is associated with music X1 to music X3 as related music, and the keyword: movie title “XXX” ( The schedule information "movie") is associated with songs X4 to X6 as related songs, and the keyword: "Hokkaido" (same schedule information as "Hokkaido") is associated with songs X7 to X10 as related songs. The keywords: baseball team name "●●●" (same schedule information as "●●●") are associated with songs 11 to X14 as related songs.

Here, it is assumed that the extraction unit 22b extracts the soccer team name “△△△” as the event schedule information as described in the above example. In this case, the specifying unit 22c refers to the table of FIG. 5 and specifies the songs X1 to X3 associated with the soccer team name “△△△”.

The specific unit 22c transmits the specified related music to the user terminal that has transmitted the schedule information. Specifically, the specific unit 22c transmits the music name and music ID of the related music. On the other hand, when an undelivered song is specified for the karaoke device, the identification unit 22c may transmit performance data for playing the song. The performance data of the music is stored in the storage means 20.

When the related music is received, the presentation unit 14b of the user terminal causes, for example, the display means 12 to display the music name of the related music in a list format. The user selects a song for which karaoke singing is desired from the displayed songs via the input means 13. The transmission processing unit 14a of the user terminal transmits the music ID of the selected music to the paired karaoke device via the server device S. The karaoke device registers the received music ID in the reservation queue and performs karaoke performances in order.

The related music may be presented at the timing when the related music is received from the extraction unit 22b, or may be presented only when the music is not reserved from the user terminal for a predetermined time. Further, the presentation unit 14b may present not only the music name but also the music ID, the singer name, and the like. Further, when the number of related songs is small, the presentation unit 14b can also present the related songs by voice via the speaker (not shown) of the user terminal M.

== Processing in the music recommendation system ==
Next, the processing in the music recommendation system 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing processing in the music recommendation system 1. In this example, it is assumed that the user U has registered the schedule information in the user terminal M in advance. Further, it is assumed that the karaoke application is executed on the user terminal M owned by the user U. Further, it is assumed that the server device S has completed the pairing between the karaoke device K and the user terminal M.

The transmission processing unit 14a of the user terminal M transmits the schedule information of the registered user U to the server device S (transmission of schedule information. Step 10).

The extraction unit 22b of the server device S extracts the event schedule information indicating the event personally planned by the user from the received schedule information and the event schedule information included within the predetermined period.

When the event schedule information can be extracted from the schedule information acquired from the user terminal (in the case of Y in step 11), the identification unit 22c specifies the related music corresponding to the extracted event schedule information (identification of the related music). Step 12).

The identification unit 22c transmits information indicating the related music specified in step 12 to the user terminal M (transmission of the related music, step 13).

The presentation unit 14b of the user terminal M presents the related music specified in step 12 to the user U (presentation of the related music. Step 14).

On the other hand, when the event schedule information cannot be extracted from the schedule information acquired from the user terminal (in the case of N in step 11), the extraction unit 22b transmits the schedule information to the search system (sends the schedule information to the search system). Transmission. Step 15). The search system searches for reference information corresponding to the received schedule information. The search system transmits the search result to the server device S.

The extraction unit 22b extracts the event schedule information based on the search result acquired from the search system (extracts the event schedule information according to the search result. Step 16). After that, the server device S performs the same processing as in steps 12 to 14.

As is clear from the above, the music recommendation system 1 according to the present embodiment includes the server device S and the user terminal M communicably connected to the server device S. The server device S is event schedule information indicating an event personally planned by the user U from the schedule information acquired from the user terminal M owned by the user U of the karaoke device K, and within a predetermined period. It has an extraction unit 22b for extracting the included event schedule information, and a specific unit 22c for specifying the related music corresponding to the extracted event schedule information. The user terminal M has a presentation unit 14 that presents the specified related music to the user U.

According to such a music system 1, it is possible to present to the user related music corresponding to the event schedule information personally planned by the user. The related music is a music closely related to the event planned by the user. Therefore, by selecting related songs, the user can enjoy the afterglow of the event and raise his / her feelings for the event to be held in the near future. Further, when a plurality of users use the karaoke device K, the place of karaoke singing can be excited by singing such related songs. That is, according to the music recommendation system 1 according to the present embodiment, it is possible to recommend music related to the event personally planned by the user.

Further, when the event schedule information cannot be extracted from the schedule information acquired from the user terminal, the extraction unit 22b according to the present embodiment can extract the event schedule information based on the search result acquired from the search system. By using the external search system in this way, the event schedule information included in the schedule information can be extracted more reliably. If the event schedule information cannot be extracted from the schedule information acquired from the user terminal, the server device S may end the process without transmitting the schedule information to the search system. Alternatively, if the event schedule information cannot be extracted based on the search result acquired from the search system, the server device S may end the process as it is.

<Modification example 1>
For example, a week later, multiple fans attending Artist Y's concert may visit a karaoke store together. In such a case, it is highly possible that the same event schedule information (artist Y's concert) is registered in the user terminal of each fan (that is, the user). Therefore, there is a possibility that the karaoke singing place will be excited by recommending songs that are closely related to artist Y to each fan. Therefore, the music recommendation system 1 of this modified example preferentially recommends related music corresponding to common event schedule information.

Specifically, the extraction unit 22b extracts the common event schedule information when the schedule information is acquired from each of the plurality of user terminals and the event schedule information is common to the plurality of schedule information. ..

In this case, the specific unit 22c specifies the related music corresponding to the common event schedule information. The presentation unit 14a of each of the plurality of user terminals preferentially presents the related music corresponding to the common event schedule information.

In addition to these processes, individual event schedule information is extracted from the schedule information of each user by the same process as in the first embodiment, and the related music corresponding to the extracted event schedule information is specified. Is also possible.

That is, it suffices that the extraction unit 22b in this modification can at least extract the common event schedule information. Further, the specific unit 22c only needs to be able to specify at least the related music corresponding to the common event schedule information. Further, the presentation unit 14a only needs to be able to present at least the related music corresponding to the common event schedule information.

<Modification 2>
In the description of the above embodiment, the predetermined period is set to "within 15 days from the present time", and one related song is sufficient, but the present invention is not limited to this. For example, a predetermined period may include a period before the time when the event schedule information is extracted, and two or more related songs may be associated with the event schedule information. In this case, the specific unit 22c identifies different related songs depending on whether the event schedule information is extracted before the event indicated by the event schedule information is executed or after the event is performed. be able to.

Specifically, when the event schedule information V is extracted before the event v indicated by the event schedule information V is executed, the specific unit 22c selects the up-tempo and bright music XU among the plurality of related songs. It can be specified as a related song. In this case, the user can raise his / her feelings for the event that will come in the near future. On the other hand, when the event schedule information V is extracted after the event v is performed, the specific unit 22c may specify the music XB such as a ballad different from the music XU as the related music among the plurality of related songs. it can. In this case, the user can enjoy the afterglow of the event v.

Alternatively, if the event is the live L of the artist N and the event schedule information is extracted before the live L, the specific unit 22c specifies the music that the artist N often sings at the opening of the live as a related music. be able to. In this case, the user can get excited while imagining the moment when the live starts. On the contrary, when the event schedule information is extracted after the live L, the identification unit 22c can specify the music that the artist N often sings in the live encore as the related music. In this case, the user can look back on the final excitement of the live performance.

<Others>
In the above embodiment, an example of specifying a related music using a table of related music has been described, but the present invention is not limited to this. For example, using the singing history of the user, a song that is sung by many users who have registered the same event schedule information in the past may be specified as a related song.

Also, depending on the event schedule information, there may be a large number of related songs. In such a case, the specific unit 22c may randomly extract some from a large number of stored related songs and specify them as related songs. Alternatively, the specific unit 22c may specify a part (for example, the top three songs of songs frequently sung in karaoke) as related songs from a plurality of related songs based on the singing history.

The above-described embodiment is presented as an example and does not limit the scope of the invention.
