we started to collect useful tools for NLP related tasks implemented in the Ruby programming language since it's our favorite one:
https://github.com/arbox/nlp-with-ruby
We do care about diversity so every NLP developer could reuse libraries in form of JRuby + Java projects, pure Ruby tools or Ruby + Python + Clojure + AWK + Perl + whatever pipelines with clear text based interfaces.
If you find it interesting, please use this list for your tooling. If you have a good tool, please consider contributing it to the list.
Best, Andrei Beliankou
