GATE (http://gate.ac.uk) is open source and allows to create annotations manually. The interface is tightly bound to the GATE API so porting it to UIMA would be a relatively costly operation. It would certainly be easier to write a new annotation tool from scratch. However GATE could be used in the meantime to annotate documents and save them as XML, which could be loaded by UIMA at a later stage.

There is also a UIMA plugin for GATE which allows to call UIMA processes from GATE and vice versa; but I am not sure it works with the Apache version of UIMA. That could help using existing UIMA resources for pre-annotating documents.

Hope that helps

BTW, I have recently hacked UIMA's CAS Visual Debugger for a colleague to allow creating manual annotations. That was a one-off, though, and I haven't fed it back into the main code base. If people are interested in that kind of functionality, let me know. We wouldn't want to compete with a dedicated annotation tool, though.

I would like to second Andrew Borthwick's original request for a UIMA-savvy annotation tool. Adding it to a full-featured annotator would probably be great, but having an open source option would offer the most potential upside for UIMA. Alembic and its replacement Callisto are free, but not open source, so I believe MITRE would have to add support for UIMA themselves. Are there any open source annotators people would recommend for integrating with UIMA? -j -- Joe Andrieu SwitchBook Software http://www.switchbook.com joe-WWIN1AkEjBuIuWR1G4zioA@public.gmane.org +1 (805) 705-8651
