The configuration of the server device S will be described with reference to FIG. As shown in FIG. 4 , the server device S includes storage means 20 , communication means 21 and control means 22 . Each configuration is connected to bus B via an interface (not shown).

[Storage means, communication means]
The storage unit 20 is a large-capacity storage device that stores various data. In the present embodiment, the storage unit 20 pre-stores keywords corresponding to event schedule information (described later) and related music (described later) associated with the keywords. Keywords may be specific movie titles, artists' live performance names, professional baseball team names and venues where they are held, as well as names of sightseeing spots nationwide, famous facility names and abbreviations, etc. There may be. The communication means 21 provides an interface for communicating with the user terminal M, the karaoke machine K, and an external search system (described later).

[Control means]
The control means 22 performs various controls in the server device S. FIG. The control means 22 includes a CPU and memory (both not shown). The CPU implements various functions by executing programs stored in the memory. In this embodiment, the control unit 22 functions as a pairing processing unit 22a, an extraction unit 22b, and an identification unit 22c.

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

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

(Extraction part)
The extraction unit 22b extracts event schedule information indicating an event personally planned by the user from schedule information in which the user's schedule is registered, which is obtained from a user terminal owned by the user of the karaoke device, And extract the event schedule information included in the predetermined period.

For an event personally planned by a user, information on "place" is registered. "Birthday" is an event that must be visited regardless of the presence or absence of personal plans, and "location" is not registered.

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

Moreover, 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 results 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, assume that the schedule information shown in FIG. 3 is obtained as of July 6, 2019. FIG. In addition, "within 15 days from the present time" is set as the predetermined period, and in the storage means 20, keywords corresponding to the event schedule information are the soccer team name "△△△", the baseball team name "●●●", It is assumed that the movie title "XXX" and the travel destination "Hokkaido" are stored.

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

On the other hand, the schedule information relating to “movie” and “watching soccer” do not match the keywords stored in the storage means 20 . That is, the extraction unit 22b cannot extract event schedule information.

In this case, the extraction unit 22b transmits the schedule information of "movie" and "watching soccer" together with the date of each event to the search system. Specifically, the extracting unit 22b extracts "content: movie, date and time: 13:00 on July 2, 2019, place: Shibuya Theater" and "content: watching soccer game, date and time: 2019 July 16, 19:00-, Place: 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 obtains, as search results, a movie title "XXX", which is reference information corresponding to "movie", and a soccer team name "△△△", which is reference information corresponding to "watching soccer". Suppose we get The search system transmits search results to the server device S. FIG.

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

In addition, "birthday" is not extracted as event schedule information in the schedule information shown in FIG.

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

As described above, the predetermined period is "within 15 days from the current time". Therefore, the extracting unit 22b selects the current ( The baseball team name "●●●" and the soccer team name "△△△", which are the event schedule information for the next 15 days from July 6), are extracted.

It should be noted that the extraction unit 22b may extract the event schedule information by first extracting a character string included in the predetermined period and depending on whether the extracted character string matches the keyword stored in the storage unit 20. good.

In addition, since the event schedule information is arbitrarily registered by the user, it does not always match the stored keyword completely. For example, assume that "ΔΔΔ" is stored as a keyword as in the above example. In this case, if a complete match with the keyword is requested, 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 and the keyword included in the schedule information. For example, the extracting unit 22b can extract the character string as the event schedule information when there is a word that matches the keyword in the character string, or when 80% or more of the characters are common.

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

Related songs are songs corresponding to the event schedule information among songs that can be karaoke-sung by the karaoke device. At least one related song is sufficient. For example, if the event schedule information is the name of the soccer team "△△△", the related song is associated with a song that is often heard on the soccer field (for example, the team's cheering song). Alternatively, if the event schedule information is the title of a specific concert or movie, the related music may be music of an artist performing the concert or music related to a movie being screened at a movie theater.

There is a high possibility that concerts held at concert halls and movies shown at movie theaters will differ from day to day. Therefore, it is preferable that related songs corresponding to such events are updated periodically. The server device S acquires information on concerts and movies (artist name, movie name, etc.) by accessing the search system. The server device S associates music corresponding to the acquired information about the concert or movie from among the music that can be performed by the karaoke device, and stores the music in the storage means 20 as related music.

FIG. 5 shows a table of related songs stored in the storage means 20. As shown in FIG. In FIG. 5, the keyword: soccer team name "△△△" (schedule information "watching soccer") is associated with songs X1 to X3 as related songs, 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 is "Hokkaido") is associated with songs X7 to X10 as related songs. Keyword: baseball team name "●●●" (same schedule information "●●●") is associated with songs 11 to X14 as related songs.

Here, it is assumed that the extraction unit 22b has extracted the soccer team name "ΔΔΔ" 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 to specify the songs X1 to X3 linked to the soccer team name "ΔΔΔ".

The identifying unit 22c transmits the identified related music to the user terminal that has transmitted the schedule information. Specifically, the identifying unit 22c transmits the music title and music ID of the related music. On the other hand, when a piece of music that has not yet been delivered to the karaoke machine is identified, the identification unit 22c may transmit performance data for performing the piece of music. Music performance data is stored in the storage means 20 .

When related music is received, the presentation unit 14b of the user terminal causes the display unit 12 to display the music titles of the related music in a list format, for example. The user selects a desired song for karaoke singing from the displayed songs through the input means 13. - 特許庁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. FIG. The karaoke device registers the received song IDs in a reservation queue and performs karaoke 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. In addition, the presenting unit 14b may present not only the song title but also the song ID, the singer's name, and the like. Further, when the number of related songs is small, the presenting unit 14b can also present the related songs by voice through a speaker (not shown) of the user terminal M. FIG.

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

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

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

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

The identifying unit 22c transmits information indicating the related music identified in step 12 to the user terminal M (transmission of related music; step 13).

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

On the other hand, if the event schedule information could not be extracted from the schedule information acquired from the user terminal (N in step 11), the extraction unit 22b transmits the schedule information to the search system (the schedule information is sent to the search system). Send, step 15). The search system searches for reference information corresponding to the received schedule information. The search system transmits search results to the server device S. FIG.

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

As is clear from the above, the music recommendation system 1 according to the present embodiment includes a server device S and a user terminal M connected to the server device S so as to be able to communicate therewith. 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 machine K, and within a predetermined period It has an extraction unit 22b that extracts the included event schedule information, and an identification unit 22c that identifies 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. FIG.

According to such a music system 1, related music corresponding to event schedule information personally planned by the user can be presented to the user. A related song is a song closely related to the event planned by the user. Therefore, by selecting related music, the user can enjoy the afterglow of the event and feel excited for the event to be held in the near future. Also, when a plurality of users use the karaoke apparatus K, singing karaoke of such related music can enliven the karaoke singing place. That is, according to the music recommendation system 1 according to the present embodiment, it is possible to recommend music related to an event personally planned by the user.

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

<Modification 1>
For example, a week later, a plurality of fans attending a concert of artist Y may visit a karaoke parlor together. In such a case, there is a high possibility that the same event schedule information (artist Y's concert) is registered in the user terminals of the respective fans (that is, users). Therefore, there is a possibility that the karaoke singing venue will be lively 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, when the schedule information is acquired from each of a plurality of user terminals and there is event schedule information common to the plurality of schedule information, the extracting unit 22b extracts the common event schedule information. .

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

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

That is, the extracting unit 22b in this modified example only needs to be able to extract at least the common event schedule information. Further, the specifying unit 22c only needs to specify related songs corresponding to at least common event schedule information. Furthermore, the presenting unit 14a only needs to be able to present related music corresponding to at least common event schedule information.

<Modification 2>
In addition, in the description of the above embodiment, the predetermined period is "within 15 days from the current time", and it is sufficient that there is only one related song, but the present invention is not limited to this. For example, the predetermined period may include a period before the extraction of the event schedule information, and two or more related songs may be associated with the event schedule information. In this case, the specifying unit 22c specifies different related songs for certain event schedule information, depending on whether it was extracted before or after the event indicated by the event schedule information. be able to.

Specifically, when the event schedule information V is extracted before the implementation of the event v indicated by the event schedule information V, the specifying unit 22c selects the up-tempo and bright tune XU from among the plurality of related tunes. It can be specified as a related song. In this case, the user can get excited about the upcoming event in the near future. On the other hand, when the event schedule information V is extracted after the implementation of the event v, the specifying unit 22c can specify, among the plurality of related songs, the song XB such as a ballad different from the song XU as the related song. can. In this case, the user can enjoy the afterglow of event v.

Alternatively, if the event is an artist N's live L, and the event schedule information is extracted before the performance of the live L, the specifying unit 22c specifies a song often sung by the artist N at the opening of the live as a related song. be able to. In this case, the user can get excited while imagining the moment the live performance starts. Conversely, when the event schedule information is extracted after the performance of the live L, the specifying unit 22c can specify a song that the artist N often sings during live encores as a related song. In this case, the user can look back on the excitement at the end of the live.

<Others>
In the above-described embodiment, an example in which related songs are identified using a table of related songs has been described, but the present invention is not limited to this. For example, a user's singing history may be used to specify, as a related song, a song sung in karaoke by many users who have registered the same event schedule information in the past.

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

The above embodiments are presented as examples and are not intended to limit the scope of the invention. The above configurations can be implemented in combination as appropriate, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the scope and spirit of the invention, as well as the scope of the invention described in the claims and equivalents thereof.
