Enquadramento
Audio music mood-based analysis is a research area of increasing interest in Music Information Retrieval (MIR). It has a wide range of applications in fields such us automatic music classification, automatic playlist generation and similarity analysis.
In fact, recent studies identify music mood/emotion as an important criterion used by people in music retrieval and organization. Moreover, music psychology and education recognize the emotion component of music as the one most strongly associated with music expressivity.
The analysis of audio music in terms of mood/emotion is challenging in its very nature: mood is a subjective notion, techniques are still in an embryonic stage and a uniform evaluation framework is yet to be agreed upon. Nevertheless, the Music Information Retrieval Evaluation eXchange (MIREX, a small “competition” that takes place every year), has in 2007 (and for the first time) a track on audio music mood classification, which will certainly give a strong impulse towards the improvement of techniques and creation of evaluation standards.
Objetivo
The main objective of this thesis is to implement a software tool able to the track the mood
variations throughout an audio musical clip, e.g., contentment, depression, exuberance and
anxiety. This involves the study and derivation of mood-like features, mood-based similarity
metrics (namely self-similarity metrics) and ranking.
