This is the implementation of our personalized blog tagger. It was built for tagging blogs, but it could be applied to any collection of documents with text labels. The paper summarizing our results can be found here
I just uploaded this project and an intrepid progammer can read the source code to determine the XML-RPC calls to make the tagger go. I will by the end of the week have uploaded some documentation, most likely on a wiki. The project can be accessed here.
