Open Source Natural Language Processing?

fieldmethods asks: "One area where Open Source and Free Software doesn't seem to have really taken off is Natural Language Processing (using computers to deal with human languages). There are a few projects that are open source, such as Festival (a speech synth system, now ported to Java), NLTK, a general-purpose NLP system in Python, and the Linguana project, a Perl implementation of a semantic network not unlike Wordnet (but better). Generally, though, there doesn't seem to be a lot of Open Source momentum behind the field as a whole. It's a challenging, difficult field that would benefit from collaboration, especially given the potential of replacing static corpora with on-the-fly corpora developed by search engines. Is anybody else interested in this?"

Did you google?

Is there a reason you haven't tried answering your question using Google? You're not chasing karma are you? Last I heard Google is free.

There's a huge amount of open-source NLP resources and software for many languages on the web.

• Thought Treasure - a bilingual database of 25000 concepts including 55000 English and French words and phrases. Compiles under Linux and Windows

• Leeds University NLP Research Group (mail webmaster re broken links to software)

• Japan's ICOT/5th Generation Computer Project archive of free software

• Linguistics Toolset at Vaasa University

Last but not least:

• A well-annotated collection of NLP links including NLP, NLU, Speech*, MLT, Fuzzy*, MLPs, SVMs, etc

Will.
