Can Perl be used for natural language processing?

Answer 1

Yes, Perl is really good to process text and natural language, the Perl Regex, for example. I can say it's better for custom solutions.

See here the Perl module Lingua::StanfordCoreNLP, binding to the Stanford NLP, original in Java:

https://metacpan.org/pod/Lingua::StanfordCoreNLP

You will find several modules on CPAN, for NLP, implementing bindings, and API clients to NLP services (IBM, Google, etc):

https://metacpan.org/search?size=20&q=nlp.

Or try the Lingua modules:

Enjoy!
