Original Kurzfassung:
We present a novel user interface that offers a fun way to
explore music collections in virtual landscapes in a gamelike
manner. Extending previous work, special attention is
paid to scalability and user interaction. In this vein, the
ever growing size of today's music collections is addressed
in two ways that allow for visualizing and browsing nearly
arbitrarily sized music repositories. First, the proposed user
interface deepTune employs a hierarchical version of the Self-
Organizing Map (SOM) to cluster similar pieces of music using
multiple, hierarchically aligned layers. Second, to facilitate
orientation in the landscape by presenting well-known
anchor points to the user, a combination of Web-based and
audio signal-based information extraction techniques to determine
cluster prototypes (songs) is proposed. Selecting
representative and well-known prototypes - the former is
ensured by using signal-based features, the latter by using
Web-based data - is crucial for browsing large music collections.
We further report on results of an evaluation carried
out to assess the quality of the proposed cluster prototype
ranking.
