This paper addresses the issue of automatically organizing
a possibly large music collection for intuitive access. We
present an approach to cluster tracks in a hierarchical manner
and to automatically find representative pieces of music
for each cluster on each hierarchy level. To this end, audio
signal-based features are complemented with features derived
via Web content mining in a novel way. Automatic
hierarchical clustering is performed using a variant of the
Self-Organizing Map, which we further modified in order to
create playlists containing similar tracks.
The proposed approaches for playlist generation on a hierarchically
structured music collection and finding prototypical
tracks for each cluster are then integrated into the Traveller’s
Sound Player, a mobile audio player application that
organizes music in a playlist such that the distances between
consecutive tracks are minimal. We extended this player to
deal with the hierarchical nature of the playlists generated
by the proposed structuring approach.
As for evaluation, we first assess the quality of the clustering
method using the measure of entropy on a genre-annotated
test set. Second, the goodness of the method to find prototypical
tracks for each cluster is investigated in a user study.
