Generation of Tag-Based User Profiles for Clustering Users in a Social Music Site

摘要

Collaborative tagging has become increasingly popular as a powerful tool for a user to present his opinion about web resources. In this paper, we propose a method to generate tag-based profiles for clustering users in a social music site. To evaluate our approach, a data set of 1000 users was collected from last.fm, and our approach was compared with conventional track-based profiles. The K-Means clustering algorithm is executed on both user profiles for clustering users with similar musical taste. The test of statistical hypotheses of inter-cluster distances is used to check clustering validity. Our experiment clearly shows that tag-based profiles are more efficient than track-based profiles in clustering users with similar musical tastes.
