SIMAC was the first big project funded by the European Commission coordinated by the MTG (number of contract: FP6-507142; key action IST-2.3.1.7 Semantic-based knowledge systems). It started in January 2004 and finished in April 2006.

SIMAC's main task was the development of prototypes for the automatic generation of semantic audio descriptors and the development of prototypes for exploration, recommendation, and retrieval of music. One special feature was the development and use of semantic descriptors. That is, ways to tag music that are close to the user's way of describing its contents. We developed tools to be used by music consumers, music distributors, and music creators.
