Toward Web 2.0 music information retrieval: Utilizing emotion-based, user-assigned descriptors
H. Lee, and D. Neal. Proceedings of the American Society for Information Science and Technology44 (1):
This paper presents a study on emotional music retrieval. The study used music by glass (a musician) that was already indexed in matters of which emotions are evoked and classic music pieces that can be considered emotion-provoking. These prototype music-pieces were presented to a group of people who were then asked to assign specific emotions.
