Cluster Analysis on musical data from Last.Fm
The modularity clustering of the graph with last.fm similarities is compared to
the qualtiy threshold clustering with our similarities.
The nodes of the modularity clusters are connected by edges.
The colors represent the quality clustering.
Clusters C-60, C-55, C-54, C-49 and C-48 almost perfectly correspond to the
clusters found in the last.fm graph (C-61, C-58, C-77, C-62, C-52).
The union of C-38, C-24 and C-11 corresponds to the last.fm cluster C-73.
The latter three clusters have each a quite different but strongly preferred composer.
This indicates that our similarity measure performs better than the one
of last.fm
