Contribute to NLTK
==================

The Natural Language Toolkit exists thanks to the efforts of dozens
of voluntary developers who have contributed functionality and
bugfixes since the project began in 2000 (`contributors <https://github.com/nltk/nltk#contributing>`_).

In 2014 we are especially keen to improve NLTK coverage for:
`dependency parsing <https://github.com/nltk/nltk/wiki/Dependency-Parsing>`_,
`machine translation <https://github.com/nltk/nltk/wiki/Machine-Translation>`_,
`sentiment analysis <https://github.com/nltk/nltk/wiki/Sentiment-Analysis>`_,
`twitter processing <https://github.com/nltk/nltk/wiki/Twitter-Processing>`_.

New material in these areas will be covered in the second edition of
the NLTK book, anticipated in 2015.
