<p><P>PROBLEM TO BE SOLVED: To provide a data classification device, a data classification method and a data classification program, which allow to easily obtain a trend of music while effectively using a display screen. <P>SOLUTION: A metadata group generation part generates metadata groups obtained by classifying a plurality of music data, and metadata groups obtained by further classifying each metadata group. A coordinate data calculation part calculates coordinate data of metadata group area of each metadata group so that a metadata group area larger in the number of music data has a larger size of area. A metadata display screen generation part displays a metadata display screen, based on the coordinate data of metadata group areas calculated by the coordinate data calculation part, so that the larger the metadata display screen, the larger the number of display layer. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
