DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for determining an emotion attribute of a work and a method for updating a work database using the same, and more particularly, to a method for updating a work database on the Internet or a hard disk of a personal computer (hereinafter referred to as a personal computer). A method for determining the emotion attribute of a copyrighted work, which is capable of easily extracting music suitable for the emotion at that time from a large number of music libraries suitable for use in the stored music library, and using the method. How to update the copyrighted work database.

[0002]

2. Description of the Related Art Recent improvements in the performance of personal computers and the development of data compression technology have made it possible to easily store music on the hard disk of personal computers.
Compared to the conventional case of using a removable recording medium such as a cassette tape, MD, CD, etc., it is possible to select a desired song from a large library of songs by a simple operation. . For example, software that converts music CD data into MP3 files and creates an album for yourself is also commercially available.

[0003] However, in order to select a specific song to listen to, it is necessary to know the song title and album title, or the names of artists such as composers and singers.
By specifying these, the music is selected.
Therefore, vague requests that do not need to identify the song itself, such as "I want to listen to songs with a fun atmosphere, any song is fine" or "I want to listen to songs with a calm atmosphere because emotions are high" Can not respond.

[0004] Therefore, it is necessary to provide an automatic music selection means in which a user (listener) inputs his / her current mood and automatically selects and reproduces music suitable for the mood. For example, by using a database that links a song with the atmosphere (tune) of the song, it is possible to select and reproduce a song corresponding to that just by specifying the atmosphere of the music that one wants to listen to now.

[0005] In such an automatic music selection system, there is a problem in creating and updating a database linking music pieces and tunes. The following creation methods have been proposed.

(1) A method in which a human actually listens to a song, judges the tone of the song, and creates a database (for example, someone discloses a database in which a song is added to a song).

(2) A method of automatically creating a database by judging the tune from the lyrics (for example, JP-A-9-212)
480, the atmosphere information generation device and the karaoke device).

(3) A method of judging a tune from a volume, a tempo, or the like, and automatically creating a database.

[0009]

However, (1)
According to the method described above, since it takes a long time from the release of the music to the release of the music tone database or the input of the music to the database, it is impossible to perform automatic reproduction including the latest music. In addition, it is not practical to determine the tone of all of a large number of music pieces because it requires a lot of man-hours and costs.

[0010] In the case of (2), the tune cannot be determined for a song having no lyrics.

[0011] Further, the method (3) has a problem that an algorithm for accurately judging the tune has not been completed, and there is a high possibility that an erroneous judgment is made.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is possible to obtain information representing a feeling of a musical piece or the like with high precision without evaluating the contents of a copyrighted work such as a musical piece, and at the same time, obtain a copyrighted information. An object of the present invention is to make it possible to update a database immediately after a product is released.

[0013]

According to the present invention, when determining the emotional attributes of a work (for example, a song, a document, a book, a picture, a play, a script of a play, etc.), the content of the work is evaluated without evaluating the content of the work. By determining information representing emotions from external shape information at the time of reference (for example, a list of broadcasted songs, a list of published articles (comments), a list of performed (played) plays, etc.), This has solved the above-mentioned problem.

Here, the reference means that a work is selected, the selected work is shown, and then the work is used. It is not necessary to refer to all or a part of the work at the time of reference.

As a specific example of the reference, in the case of broadcasting, “selection of a copyrighted work” is the selection of music to be broadcast,
"Indicate what the selected work is" means information that can identify the song, such as the song title of the song to be broadcast,
“Using a copyrighted work” means broadcasting a music.

As another example, in the case of a book review on a newspaper, "selection of a work" means selecting a book to be reviewed, and "showing what the selected work is". Is the title of the book being reviewed and the International Standard Book Number (ISB
N), which indicates information that can identify a book, and "using a work" means posting a book review of the work.

As yet another example, in the case of a play (script), “selecting a work” means selecting a script to be performed, and “indicating what the selected work is” is a performance. This is to indicate information that can identify what the script is, and "using a work" means performing a play based on the script.

In addition, the outer shape information is used to determine the situation and background when referring to a copyrighted work (for example, the situation and background when music used for broadcasting is selected, the situation when books and plays to be reviewed are selected, and the like). Background, situation and background when the drama to be performed is selected, etc .... The music selection and selection include the intention (emotion) of the selected music or the selected person or organization) It is.

Further, the link relationship between the outer shape information and the emotion information is made variable to facilitate the correction according to the human sense.

The present invention also solves the above-mentioned problem by updating the attribute of a corresponding work in a work database using the emotion information determined by the above-described emotion attribute determination method.

Further, the present invention is a computer program for implementing the emotion attribute determining method or the work database updating method.

Further, the present invention is a computer-readable recording medium on which the computer program is recorded.

[0023] The present invention also solves the above-mentioned problem by providing a device for determining emotional attributes of a work without evaluating the contents of the work in an apparatus for determining emotional attributes of the work. It is.

[0024] Further, the external form information may be obtained by
It further comprises means for acquiring from the state at the time of distribution.

Further, a means for making the link relationship between the outline information and the emotion information variable is further provided to facilitate correction according to human senses.

According to the present invention, there is also provided a copyrighted work database updating device for updating an attribute of a copyrighted work in a copyrighted work database using the emotion information determined by the emotion attribute determining device according to any one of the above. By providing the above, the above-mentioned problem has been solved.

The selection of a literary work such as the reproduction of music can be performed in the following order, for example.

(1) The order in which the scores of emotion information are high

(2) Random order of a predetermined number a) The predetermined number is limited by the number of works (desired number of songs or volumes) b) The predetermined number is limited by the amount of works (desired reproduction time or number of pages) c) The predetermined number is limited when the emotion information is equal to or higher than the predetermined point.

[0030]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention applied to a tune database of an automatic tune selection system for automatically selecting and reproducing a tune suitable for the atmosphere of a tune desired by a user will be described below. This will be described in detail.

Generally, a radio broadcast station has a color unique to the station, and the fan layer differs for each station. This unique color is also reflected in the type of music to be broadcast, and there is a tendency for the music tone of the music to be aired for each broadcasting station. This tendency is further strengthened by the music played in the program and the selection of the disc jockey in charge of the music.

On the other hand, the record company has a C
As part of the promotion of D and records, radio stations are broadcasting songs before the release from a very early stage before the CD is released. In addition, many radio stations publish their own broadcasted songs, and some broadcast stations publish a list (broadcast list) of songs broadcast on that day on the Internet.

Therefore, as shown in FIG. 1, if the broadcast list 20 of the radio station is obtained via the Internet 22, for example, the outer shape information relating to the latest music can be obtained in the database of the automatic music selection system 30.

Therefore, in the automatic music selection system 30, a broadcasting station, a broadcast program, a disc jockey (DJ), a broadcasting time zone (for example, a song that is bright in the daytime, a song that is slow in the night), and the weather at the time of broadcasting (for example, a sunny day is bright) A database (referred to as a broadcast station-song DB) 3 for managing a link between the key and the song, using a song, a song where rain is calm, and the like as a “key” 3
2 and the broadcast station-song DB 32, for each broadcast station, based on the music selection tendency, for example, emotions such as "fun atmosphere", "relaxation", "elevation", "sad", etc. (Referred to as broadcast station-emotion information DB) 34 for managing parameters (referred to as emotion information) representing
And acquires the tune of the music based on the emotion information of the key linked to the music.

If the user 10 determines that the tune of the song is not appropriate, the user 10 instructs the automatic song selection system 30 to indicate the tune of the song, and the key to which the song is linked is determined. Emotion information can be modified.

In addition, when a song link is added to a key, if the song to be added is also linked to another key, the song is added based on the emotion information of the other key. Key emotion information can be modified.

When a broadcast station is used as a key, a link to the music is created from a music list broadcast by the broadcast station. When a broadcast program is used as a key, a link to a song can be created from a song list broadcast in the program. Further, when DJ is used as a key, a link to a song can be created from a song list broadcasted by the DJ in a program.

Specifically, the broadcast station-song DB 32
As shown in FIG. 2, when one music is broadcasted by a plurality of broadcasting stations, a music link is added to each broadcasting station. If the same song is broadcasted many times at the same broadcasting station, a link is added according to the number of broadcasts. That is, the multiplicity corresponding to the number of broadcasts is provided. FIG. 3 shows a specific example of the broadcast station-song DB 32, and FIG. 4 shows an example in which the number of broadcasts for each broadcast station is tabulated.

On the other hand, as shown in FIG. 5, a score is set in the broadcast station-emotional information DB 34 for each parameter representing emotion.

Therefore, based on a broadcast list (also referred to as an on-air list) 20 published by each broadcast station on the Internet 22, for example, information is added as shown in FIG. A broadcast station-song DB 32 for managing a link between a key and a song is created, or information is added to an already created DB. At this time, information that is not described in the on-air list (for example, weather) can be obtained from another database such as the Meteorological Agency based on the broadcast time.

In the example of FIG. 4 obtained by summing up FIG. 3, for example, when attention is paid to music 1, the broadcast is broadcast once at broadcast station 1, twice at broadcast station 2, and twice at broadcast station 5. FIG. 4 shows songs 1 to 13
For each of the above, the number of broadcasts by which broadcast station and how many times are shown.

In order to acquire the emotion information for the music, a broadcast station-emotion information DB prepared in advance as shown in FIG.
Calculation is performed using the scores of emotion information set for all the broadcasting stations linked to the music described in No. 34, and the average is calculated.

For example, when the value of “bright” of the song 1 is calculated, the value of the broadcast station 1 “bright” broadcasted once is 7
0.0, broadcast station 3 broadcast twice, 40.0,
Since broadcast station 5 broadcasted twice is 60.0, the arithmetic average is
It becomes 58.0 as shown in the following equation.

(70.0 × 1 + 40.0 × 2 + 60.0 × 2) / (1 + 2 + 2) = 58.0 (1)

Therefore, the value of “bright” in music 1 is 58.
It becomes 0.

The value of "bright" may be calculated using a geometric mean, a harmonic mean, a root mean square or the like in addition to the arithmetic mean. In the case of the geometric mean, 57.5 as shown in the following equation.
Becomes

(70.0 × 40.0 ² × 60.0 ² ) ^1/5 = 57.5 (2)

The value thus obtained is used as the value of the emotion information for the music. It should be noted that a weight may be assigned to a broadcast station having a large bias in song selection when calculating the average. Conversely, the weight may be lightened for a broadcast station that has no bias in song selection and has few features as a station.

FIG. 6 shows an example in which each emotion and each song are calculated by the arithmetic mean, and FIG. 7 shows an example in which the arithmetic is calculated by the geometric mean. By using this table, emotion information of each song can be checked.

The calculation of the emotion information for the music may be calculated in advance in batches at idle time such as at night in order to reduce the load at the time of music selection. If the speed of the personal computer is high, it is possible to omit the place where the value of the emotion information for the music is stored by calculating in real time at the time of music selection.

When a link to another broadcast station is to be added to a song that already has a link to one or more broadcast stations, the emotion of the broadcast station to which the song is added is determined based on emotion information about the song. Information can be modified. In this case, the change in the value of the emotion information of the broadcast station is larger as the number of songs linked at that time is smaller, and conversely, the change is smaller as the number of linked songs is larger. To

For example, if the music already linked is n
If the value of emotion information i of a song and a certain emotion information i is Fi, the value of emotion information i of the music to be added is fi, and the modified value of Fi is Fi ',
It can be expressed by the following equation.

Fi ′ = (Fi × n + w × fi) / (n + w) (3) Here, w is a weighting factor and is usually 1, but especially when it is desired to increase the influence of a new song, w is increased. In order to reduce the influence, it can be set to 1 or less.

When actually listening to a song using the song database created / modified as described above, FIG.
As shown in (system configuration) and FIG. 9 (flowchart), first, in step 100, the tune (atmosphere) that the user 10 wants to listen to is specified as, for example, “bright feeling”. Then, at step 102, the broadcast station-song DB at that time
32 and the data of the broadcasting station-emotional information DB 34,
For example, a tune value (a value of emotion information) of a tune is calculated in real time and temporarily stored in the tune value DB 38. It should be noted that it is also possible to calculate the idle time in batches in advance so that the rise can be made earlier. Also, the music to be reproduced may be in a place other than the user's personal computer.

Then, the process proceeds to a step 104, wherein the emotion information on the musical piece having a high value of “bright” is converted to the musical tone value D.
B38, a reproduction list 40 is created, and reproduction is performed in step 106. At this time, it is not always necessary to reproduce in order from the highest one. If the music is played back in order from the highest one, the same music is likely to be reproduced every time the same atmosphere is selected unless a new music is added. For example, the score is equal to or higher than a predetermined value or the highest. It is possible to set a predetermined number of songs, or a reproduction time, and so on, and to play back even those having a low value to some extent, and to reproduce them randomly from among them.

It should be noted that a plurality of emotion information may be specified when specifying a desired tune.

When the music is played, the selected music is
In step 108, it is determined whether or not the music piece is appropriate for the designated tune. If the music piece is not appropriate, the value of the broadcast station-emotional information DB 34 can be changed in step 110 as shown in FIG. At this time, it is desirable to correct the emotion information of the broadcast station in the same manner as when linking a song that is always linked to one or more broadcast stations to another broadcast station. At this time, since the value of the weighting factor w is a feeling actually held by the user, it is desirable that the value of the weighting factor w be one or more or larger than that in the case of adding a link.

As described above, it is possible to acquire emotion information about a music piece immediately after it has been released, and further, the user determines that the acquired emotion information is not appropriate and corrects the acquired emotion information. It is possible to create an automatic music selection system in which the accuracy of information is further improved.

In the above embodiment, the present invention is applied to the automatic music selection system. However, the application of the present invention is not limited to this, and the present invention is not limited to this. Based on book reviews, evaluators, etc. of websites, newspapers, magazines, etc.
Obviously, the present invention can be similarly applied to a system for selecting a painting or the like. Further, the broadcast station-song DB may be provided not on the user's personal computer but on the Internet provider side.
