Unfortunately, my desire to use it is the extent of my knowledge on the subject.  Separate searches in the Processing Forum for Natural Language Processing and RitA aren't of that much help, but a bit.  You might need to seek out advice on architecture on NLP forums and try to port it to Processing where the community can help you debug your conversion.

 

Let us know how it goes.  It's a super interesting subject that a lot of community members could benefit from knowing more about.
