On Evaluation Validity in Music Autotagging
[article]
2014
arXiv
pre-print
Preserved Fulltext
Music autotagging, an established problem in Music Information Retrieval, aims to alleviate the human cost required to manually annotate collections of recorded music with textual labels by automating the process. Many autotagging systems have been proposed and evaluated by procedures and datasets that are now standard (used in MIREX, for instance). Very little work, however, has been dedicated to determine what these evaluations really mean about an autotagging system, or the comparison of two

... systems, for the problem of annotating music in the real world. In this article, we are concerned with explaining the figure of merit of an autotagging system evaluated with a standard approach. Specifically, does the figure of merit, or a comparison of figures of merit, warrant a conclusion about how well autotagging systems have learned to describe music with a specific vocabulary? The main contributions of this paper are a formalization of the notion of validity in autotagging evaluation, and a method to test it in general. We demonstrate the practical use of our method in experiments with three specific state-of-the-art autotagging systems --all of which are reproducible using the linked code and data. Our experiments show for these specific systems in a simple and objective two-class task that the standard evaluation approach does not provide valid indicators of their performance.

Freesound.org is an online sound database with over 200.000 sounds now, which everyday serves the purpose of sound designers, composers and creative artists, providing them with Creative Commons license sounds for them to build musical compositions, interactive installations, build applications, movie soundtracks, etc. The need for optimized ways to serve musical content in this platform, as in others, is much needed, in order not to avoid leaving many sounds to be unexplored and never

... . What this work proposes is to develop a content based approach to classify sounds into a two level taxonomy. The first level consists of the classes Speech, Sound Effects, Soundscape, Mu- sic and Instrument. The second level, consists of musically meaningful concepts, such as Chord, Single Note, Melody, among others. Two different set of features are evaluated, MFCC and spectral features against low level features, and two different classification schemes too, at against hierarchical. For classification, K-Nearest Neighbour, Support Vector Machines and Decision Trees classifiers are used. Evidence is shown the MFCCs and spectral features combined with a hierarchical model works the best. The dataset used is also made available.
