Information processing system, information processing method, and information processing program

Abstract

An information processing system according to the present disclosure comprises: an acquisition unit that acquires a query related to music search content and a category related to a music search target; an identification unit that identifies target music data, which is music data related to the query; and an extraction unit that extracts component data associated with the target music data on the basis of the category.

Claims

1. An information processing system comprising: an acquisition unit that acquires a query relating to the content of a music search and a category relating to the music to be searched; an identification unit that identifies target music data which is music data related to the query; and an extraction unit that extracts component data associated with the target music data based on the category.

2. The information processing system according to claim 1, wherein the constituent data is data relating to any of the following: phrase, instrument, lyrics, text, or metadata.

3. The information processing system according to claim 2, wherein the data relating to the phrase is MIDI (Musical Instruments Digital Interface) data.

4. The information processing system according to claim 1, wherein the identifying unit identifies the target music data by searching using the query, with the identifying unit targeting a plurality of music data.

5. The information processing system according to claim 4, wherein the identifying unit identifies the target music data corresponding to the query from among the plurality of music data to which a plurality of constituent data are associated.

6. The information processing system according to claim 5, wherein the identifying unit identifies the target music data corresponding to the query from among the plurality of music data to which the plurality of constituent data obtained by the analysis processing of each of the plurality of music data are associated.

7. The information processing system according to claim 5, wherein the identifying unit identifies the target music data corresponding to the query from among the plurality of music data to which the plurality of component data are pre-associated.

8. The information processing system according to claim 1, wherein the identifying unit identifies the target music data using a model that takes the query as input and outputs output information indicating data corresponding to the input query.

9. The information processing system according to claim 8, wherein the identifying unit identifies music data corresponding to the output information output by the model from among a plurality of music data to be searched, as the target music data.

10. The information processing system according to claim 1, wherein the acquisition unit acquires the query relating to a category other than the category, and the identification unit identifies music data associated with other component data corresponding to the query relating to the other category as the target music data.

11. The information processing system according to claim 1, wherein the acquisition unit acquires the query which includes a plurality of search contents, and the identification unit identifies the target music data by narrowing down the target of the search process based on the plurality of search contents.

12. The information processing system according to claim 11, wherein the acquisition unit acquires a query that includes a first query indicating one search content and a second query indicating another search content, the identification unit identifies music data that corresponds to the first query from among a plurality of music data that are the subject of the search process as a first-stage search result, and identifies music data that corresponds to the second query from among the first-stage search results as the target music data.

13. The information processing system according to claim 1, further comprising an output unit that outputs the extraction results from the extraction unit.

14. The information processing system according to claim 13, wherein the output unit outputs the target music data identified by the identification unit together with the component data extracted by the extraction unit.

15. The information processing system according to claim 13, wherein the identification unit identifies a plurality of target music data related to the query, the extraction unit extracts a plurality of component data associated with each of the plurality of target music data, and the output unit outputs the plurality of component data extracted by the extraction unit.

16. The information processing system according to claim 15, wherein the output unit outputs content in which the plurality of component data are displayed side by side.

17. The information processing system according to claim 16, wherein the output unit outputs the content in which the plurality of component data are arranged in score order.

18. The information processing system according to claim 16, wherein the output unit outputs content in which each of the multiple target music data is associated with each of the multiple component data.

19. An information processing method comprising: obtaining a query relating to the content of a music search and a category relating to the music to be searched; identifying target music data which is music data related to the query; and extracting component data associated with the target music data based on the category.

20. An information processing program that causes a computer to perform the following: obtain a query regarding the content of a music search and a category regarding the music to be searched; identify target music data which is music data related to the query; and extract component data associated with the target music data based on the category.
