Here are links to freely available NLP resources. The resources are from all over the world, and not necessarily affiliated with CLT.

Interactive online demos -- interactive try-it-yourself demonstrations of different NLP areas

Demo videos -- videos demonstrating interesting NLP applications

Linguistic data -- lexica, corpora and other linguistic databases

Development tools -- programs and other tools that can be used when developing NLP applications

And don't forget the CLT toolkit, of course!

CLT members can edit these pages at will. Feel free to add new links, but also to remove dead and outdated links.
