PAWS Meeting 09-23-2008

The speaker of this meeting was Rosta. The main theme was tagging and some of the subtopics were:

  • Ranking in folksonomies
  • Tag recommendation
  • Resource recommendation
There was a brief comparison between Google adapted page rank algorithm and the folkrank algorithm in the beginning of the presentation. Seems that folkrank is able to do a better job. Daniele raised the question about the applicability of TF/IDF in large amounts of text.

Rosta presented the Dogear game, a game that uses human intelligence to acquire some metadata about pictures and finished the presentation making some reference to the tag cloud tool Wordle.
