Proceedings of the 12th International Society for Music Information Retrieval Conference (ISMIR 2011),
Microblogging services such as Twitter have become an
important means to share information. In this paper, we
thoroughly analyze their potential for a key challenge in the
field of MIR, namely the elaboration of perceptually meaningful
similarity measures. To this end, comprehensive evaluation
experiments were conducted using Twitter posts
gathered during a period of several months. We investigated
23,100 combinations of different term weighting strategies,
normalization methods, index term sets, Twitter query
schemes, and similarity measurement techniques, aiming at
determining in which way they influence the similarity estimates?
Evaluation was performed on the task of similar artist retrieval.
Two data sets were used: one of 224 well-known
artists with a uniform genre distribution, the other constituting
a collection of 3,000 artists extracted from last.fm
