research interests

kind of randomly multidisciplinary actually...

  • Twitter and microblog research on the collective intelligence: (mostly as stated in the list above) not limited to Twitter per se, but also inclusive of the cornucopia of Web 2.0 social networking and content publishing sites.
  • Image processing: specifically with pixel-level processing, GLCM methods, texture/textile recognition.
  • Data mining: not too much on the theory, with more focus toward application of DM techniques (e.g. SOM & naive clusterers) on a sea of data.
  • Collective intelligence (general): Wisdom of Crowds, democracies and markets, collective action, the tipping point.
  • Political science: media analysis, electoral trends, social media expression (good example: JGill's takeover from KRudd)
  • Social networks & the new media: Web 2.0 trends, the blogosphere, memetics, social media, OSNs, Facebook et al.
