How Last.fm Illustrates the Musical World: User Behavior and Relevant User-Generated Content
In Proceedings of the international workshop on Visual Interfaces to the Social and Semantic Web, VISSW 2010, Hong Kong, China, February 17. Proceedings. (bib)

Over the last few years, online multimedia exchange plat-forms have experienced a rapid growth. They allow users to share their own content and access others in turn and hence form very large public collections of User-Generated Con-tent. While research is mostly looking at photo sharing plat-forms, such as Flickr, much less is known about online mu-sic communities. In this paper we present the results of an observational user study followed by a large-scale online survey, which investigated the behavior and the relevant content generated by the users of Last.fm, one of the most popular music communities. Based on the analysis of the results, we present implications for the usage of User-Generated Content in online music communities. Then we developed a first prototype based on the implications for improving semantic understanding of collaborative tags. We believe our study gives insights for developing informa-tion visualization and recommender systems for online mu-sic communities.
