Phrag is actually only one component of Qanda. It's a fairly simple
HMM-based phrase tagger, we use it for extracting named entities,
chunks, etc. Phrag is a bit moribund, and the distribution you're
probably using, from http://openchannelsoftware.org/ is especially old
and creaky. If you are terrifically interested in that particular
approach to information extraction, I could prepare a much more recent
distribution of Phrag. There are better-maintained extraction systems
available, however. In particular, my colleague Ben Wellner has
recently released a CRF-based tagger, Carafe:
http://sourceforge.net/projects/carafe
Ben has included models for a number of applications, including
part-of-speech, chunking, and named entity, the latter in Korean as
well as English.
If instead what you wanted was a full question answering system, sorry.
Our intent was to gradually put all of Qanda onto Open Channel, but
that never happened.
