Abstract

Quantity of music metadata on the Web is sufficient, music recommendation and online repository systems are proof of it. However, it became a real challenge to keep quality of these metadata at reasonable level as the cost of manual validation is too high and current automatic approaches are inaccurate. In this paper we present a game with a purpose called City Lights -- a music metadata validation approach which lowers the cost of human computation and makes the validation fun. Our goal is to get rid of incorrect user-submitted music tags or tags not usable at global scale. We describe the game principles and evaluate the game results.
