Abstract

A category creating apparatus receives a piece of music, extracts video image information included in the received music, and decomposes the extracted video image information with respect to each characteristic of the extracted video image information. Then, the category creating apparatus creates, with respect to each piece of decomposed video image information, a category representing the characteristic of the piece of video image information. The category creating apparatus extracts, from the video image information in the received music, character information and decomposes the extracted character information into words. The category creating apparatus creates, for each decomposed word, a category associated with the word.

Claims

1. A non-transitory computer-readable recording medium having stored therein a program causing a computer to execute a category creating process comprising:

receiving a piece of music;

extracting video image information that is included in the music received at the receiving and decomposing the extracted video image information with respect to each characteristic of the extracted video image information;

measuring an appearance time during which a characteristic appears in the music;

associating, by referring to a characteristic storing unit which stores the characteristic and a plurality of categories that represent the characteristic in an associated manner, the appearance time measured at the measuring with the plurality of categories which are stored in the characteristic storing unit; and

calculating a total time at which each category appears in the music.

2. The non-transitory computer-readable recording medium according to claim 1, further comprising:

extracting character information from the video image information included in the music that is received at the receiving; and

decomposing the character information extracted at the extracting into words, wherein

the associating includes specifying, by referring to a word storing unit which stores the plurality of categories which are stored in the characteristic storing unit and at least one word in an associated manner, a category that is associated with a word.

3. The non-transitory computer-readable recording medium according to claim 2, wherein

the measuring includes measuring appearance frequency with which the word associated with the category appears in the music, and

the associating includes associating the category with the appearance frequency.

4. The non-transitory computer-readable recording medium according to claim 3, wherein the associating includes associating the category with the appearance frequency and the appearance time.

5. The non-transitory computer-readable recording medium according to claim 3, wherein the associating includes calculating, with respect to the category, relative incidence by dividing a value, obtained by adding the appearance frequency to the appearance time, by a value, obtained by adding the total number of words contained in the character information to the total time of the music, and includes associating the category with the relative incidence.

6. A category creating apparatus comprising:

a memory which stores a characteristic and a plurality of categories that represent the characteristic in an associated manner; and

a processor coupled to the memory, wherein the processor executes a process comprising;

receiving a piece of music;

extracting video image information that is included in the music received at the receiving and decomposing the extracted video image information with respect to each characteristic of the extracted video image information;

measuring an appearance time during which the characteristic appears in the music;

associating, by referring to information which stores in the memory, the appearance time measured at the measuring with the plurality of categories which are stored in the characteristic storing unit; and

calculating a total time at which each category appears in the music.

7. A category creating method performed by an information processing apparatus, the category creating method comprising:

receiving a piece of music, using a processor;

extracting video image information that is included in the music received at the receiving and decomposing the extracted video image information with respect to each characteristic of the extracted video image information, using the processor;

measuring an appearance time during which a characteristic appears in the music;

associating, by referring to a characteristic storing unit which stores the characteristic and a plurality of categories that represent the characteristic in an associated manner, the appearance time measured at the measuring with the plurality of categories which are stored in the characteristic storing unit; and

calculating a total time at which each category appears in the music.
