Introduction

This task concerns itself with analyzing the structure of music audio files, and labeling the corresponding segments, e.g. {verse, chorus, bridge, etc}, {A, B, C, etc.}. A more detailed description can be found at the task page 2009:Structural_Segmentation. The dataset consists of 297 popular music songs.

R - Rand clustering index from Hubert & Arabie, "Comparing partitions", Journal of Classification, 1985
Fmeasure@[0.5, 3]s - segment boundary recovery evaluation measure. claimed boundary is accepted if it is within the specified window length from a true boundary, overall F-measure for boundary recovery
precRate@[0.5, 3]s - segment boundary recovery precision rate
recRate@[0.5, 3]s - segment boundary recovery recall rate
medianTrue2claim - median distance from an annotated segment boundary to the closest found boundary, seconds
medianClaim2true - median distance from a found segment boundary to the closest annotated one, seconds

The calculation of the measures is described in 2009:Structural_Segmentation#Evaluation_Measures.
