Just a quick list of natural language processing resources for Ruby:
- MIT has a list of AI-related Ruby extensions.
- Jason Adams, who does “opinion mining for a startup in Atlanta”, has a list of NLP Resources for Ruby.
- Nick Sieger has a post on RubyConf: Natural language generation and processing in Ruby.
- Finally, there are a couple of papers that mention Ruby and NLP: “Trust Region Newton Method for Large-Scale Logistic Regression” and “Natural language question answering: the view from here”.
