MIREX 2012 QBSH Task : YINLONG ’ s Solution

This extended abstract describes my submission to the QBSH (Query by Singing/Humming) task of MIREX (Music Information Retrieval Evaluation eXchange) 2012. The system takes advantage of note-based and framebased matching methods to improve the accuracy of the Query by Singing/Humming system. First, Earth Mover’s Distance (EMD), which is note-based and much faster, is adopted to eliminate most unlikely candidates. Then, Dynamic Time Warping (DTW), which is frame-based and more accurate, is executed on these surviving candidates. Finally, a weighted voting fusion strategy is employed to fusion the result of the two similarity measurement, the final decision is the one with highest scores.
