Abstract—This paper presents an extensive analysis of a sample of a social network of musicians. The network sample is first analyzed using standard complex network techniques to verify that it has similar properties to other web-derived complex networks. Content-based pairwise dissimilarity values between the musical data associated with the network sample are computed, and the relation- ship between those content-based distances and distances from network theory explored. Following this exploration, hybrid graphs and distance measures are constructed, and used to examine the community structure of the artist network. Finally, results of these investigations are presented and considered in the light of recommendation and discovery applications with these hybrid measures as their basis.
The paper mostly covers content that has been discussed elsewhere (much of it with Kurt Jacobson) refactored for a broader audience and with wider narratives in mind. That said there are some notable new findings in the paper as well. We have run another acoustic dissimilarity measure across the entire set (the 2009 MIREX entry in audio music similarity using marsyas) which for the most part confirms our earlier findings (that acoustic similarity and social similarity [mostly] aren't linearly correlated and that community genre labeling becomes more homogeneous [again, mostly] when using the audio sim as a weight). Additionally, we have broadened our comparison metrics to include an examination of the mutual information between the different dissimilarity sets. This also basically confirms our earlier findings, though mutual information provides a very satisfying level of nuance that is not possible from simply testing (using Pearsons) for linear correlation, especially given that our data is quite far from a normal distribution. So, if you're planning to be at ICASSP, I'd highly recommend IEEE-THEMES (the rest of the program looks to be very interesting as well...) and if you aren't going to be in Dallas, there are a few options for you.
- If you're in London right now, you can come to Goldsmiths today at 4pm to rm 144 in the main building, where I'll be giving a trail run of the talk.
- Slides (and perhaps some video) will be made available at some point (probably just after the talk is given).
- IEEE is running a pay-to-watch live stream of THEMES, so there's that as well.
