Abstract

In this paper two sets of evaluation experiments are conducted. First, we compare state-of-the-art automatic music genre classification algorithms to human performance on the same dataset, via a listening experiment. This will show that the improvements of content-based systems over the last years have reduced the gap between automatic and human classification performance, but could not yet close this gap. As an important extension to previous work in this context, we will also compare the automatic and human classification performance to a collaborative approach. Second, we propose two evaluation metrics, called user scores, that are based on the votes of the participants of the listening experiment. This user centric evaluation approach allows to get rid of predefined ground truth annotations and allows to account for the ambiguous human perception of musical genre. To take genre ambiguities into account is an important advantage with respect to the evaluation of content-based systems, especially since the dataset compiled in this work (both the audio files and collected votes) are publicly available.
