Recording medium, category creating apparatus, and category creating method

摘要

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.
