Perl's a great language for doing text processing, and that makes it a great language for doing Natural Language Processing as well. CPAN has an abundance of NLP modules, ranging from modules that pluralize English words and sort Klingon, to interfaces to complex databases like WordNet. In fact, there are so many NLP modules on CPAN that
trying to make sense of them all can be a daunting task for any Perl programmer. In this talk I'll do a survey of NLP modules in CPAN, concentrating on the modules under Lingua::EN::*. I'll also show how to use Perl to interface with the CMU link grammar parser libraries and with the WordNet database.
