Hello, everybody. I'm looking for papers, that define on-line communities through common itnerests. My idea is to prove, that many so-called communities in LiveJournals are not such, because there is too few discussions and other kind of interaction. So that joining such a community is mostly a demonstration of taste and part of self-presentation in their profiles. In order to prove that I want to run a PCA on the data from one of such communities like in Paolilo, Wright and Mercure's article ( http://www.scribd.com/doc/353326/The-Social-Semantics-of-LiveJournal-FOAF-St...). Their data show that there is no correlation between interests and friends and I understand it as lack of homophily. (Am I right?) So, that is my working hypothesis I want to prove. That's why I need some sources. I looked through Barry Wellman's works but he uses another approach. -- Alexander Semenov.
