「 MusicCLEF aims at promoting the development of novel methodologies for music access and retrieval, integrating content-based information, automatically extracted from music files, with contextual information, provided by users through tags, comments, and reviews. The combination of these two sources of information may help solving the actual limitations of both pure context-based (e.g. cold start, new user) and content-based (e.g. music usage, link with other media) approaches. 」
