Anybody with experiences using the Mayo Weka/UIMA Integration

[Christoph Büscher]

Hi,

does anyone on this list have experience with the Mayo Weka/UIMA Integration 
(http://informatics.mayo.edu/text/index.php?page=weka) or other Libraries that 
enable UIMA components to use machine learning algorithms?

I would be especially interested how easy/difficult the integration of Weka 
classes and algorithms was, how active the project seems to be and if anybody 
did anything else than simple test applications with it.

I'm also especially interested in UIMA components that annotate/transform text 
documents with feature representations (like TF/IDF, bag of words) usually used 
in classification in machine learning, e.g. to later train an SVM with it. Any 
ideas about existing code out there would also help a great deal.

Thanks,

Christoph
