Hi,

Unless it was updated, the KEA from Gate contrib will not work - I
don't remember all the changes that I had to do, but they were many.
Also the old plugin was using the old KEA and the new KEA is so much
better that you really don't want the old version. You can get the new
ported version of the new KEA plugin at:
http://www.roman-chyla.net/temp/kea.tgz (it includes all dependencies
and test documents with taxonomies, 40MB)  -- If you use it, please
add CERN to the copyright.

I once (actually twice) asked if there was interest of getting the new
version into GATE, but got no reply, but of course, feel free to do so
if that might be helpful to others now.

Best,

Roman
