MIREX 2010 SYMBOLIC MELODIC SIMILARITY: LOCAL ALIGNMENT WITH GEOMETRIC REPRESENTATIONS
Julián Urbano, Juan Lloréns, Jorge Morato, Sonia Sánchez-Cuadrado · 2010
This short paper describes four submissions to the Symbolic Melodic Similarity task of the MIREX 2010 edition. All four submissions rely on a local-alignment approach between sequences of n-grams, and they differ mainly on the substitution score between two n-grams. This score is based on a geometric representation that shapes musical pieces as curves in the pitch-time plane. One of the systems described ranked first for all ten effectiveness measures used and the other three ranked from second to fifth, depending on the measure.
