  • KISS
  • Open Source
  • Relatively Appl. Driven
  • No Schema

3
Some RDF Topics from MusicBrainz
4
A Taxonomy of Musical Genres (Pachet, Cazaly/Sony)
  • Typical ontology situation Not starting from
    zero, but already lots of approaches in use
    (Amazon, AMG, MP3)
  • Meta-ontology often undef., what is the
    meaning/semantics of a link
  • Genres/MetaGenres division seems mainly
    application driven (Presentation on web pages)
  • The papers design section seems to ask many of
    the right questions (methodology!).

5
Meta Genres in MP3.com, AMG, Amazon
Both AMG!, different top levels
6
MPEG-7 Ontology (Hunter)
  • Quite comprehensive
  • Multi(!) Media
  • Non-MM entities Agents, Roles, Place, Time,
    Instrument
  • Nice Web Metadata Architecture

7
Ontimusica (Chaouch LvE, work in progress)
  • Music ontology for first studies on distributed
    inferences for IR
  • Covers multiple aspects
  • Musical Genres
  • Artwork (most important distinction between the
    work an sich and the interpretation and its
    manifestation)
  • Artists and business people
  • Starting point Allmusic.com
  • Implemented in Protégé-2000
  • -( The actual version is worse than previous
    beta versions Some design and implementation
    errors!
