How do you organize music? By genre? Artists? Instruments? Is it a process that can be universalized, or is it personal?
Organizing music is the fundamental problem that the Music Genome Project attempts to solve. Named after the Human Genome Project, the Music Genome Project is a "sophisticated taxonomy of musical information"; it uses a controlled set of vocabularies to classify music and helps connect people to music they love, including ones they don't know yet.
The controversial recent Stanford study finding that organically grown food is no more nutritious than conventionally grown food is an interesting example of resource description and classification and how the resulting interactions in an organizing system come together to form conclusions. The study was a meta-analysis of previously published studies of conventional and organic food.
The 2008 presidential election clearly showed how technology (communication via social media) could be used to reach out to large segments of voters, arguably tipping the balance in the Democrat's favor. While technology is once again being used to reach out to the masses in the current election, analytics technologies are increasingly (and quietly) being used to organize prospective donors/voters.
