The OpenNLP Project provides the
official UIMA integration for the OpenNLP Sentence Detector, Tokenizer, POS Tagger,
Name Finder, Document Categorizer, Chunker and Parser.
The opennlp.uima distribution can be downloaded from the projects
download page
and includes a sample PEAR which can easily be tested with the Cas Visual Debugger.
OpenNLP has recently moved to the Apache Software Foundation, and can be found
in the Apache Incubator, here.
