That is correct - more or less.  GF is a very expressive language, and
it can handle a great deal of natural language, but it /does/ require
that the input be grammatically correct, and it is difficult to work
in unexpected vocabulary.

GF is fantastic for making flexible Controlled Natural Languages, and
it excels at producing human-readable text, but it is an entirely
different beast from a statistical natural language parser, such as

re: the original question --

The best method I've found for interfacing Haskell / Java for NLP is
to share data with some common format, such as UIMAs CAS
serialization.  We really ought to start up a group of people
interested in that over on the Haskell NLP list and see what we have
if we pool all our efforts.
