NLTK 0.9.4 has been released.
This version contains a substantially expanded semantics package
contributed by Dan Garrette, improvements to the chunk, tag, wordnet,
tree and feature-structure modules, Mallet interface, ngram language
modeling, new GUI tools (WordNet browser, chunking, POS-concordance).
The data distribution includes the new NPS Chat Corpus. NLTK-Contrib
includes the following new packages (still undergoing active
development): NLG package (Petro Verkhogliad), dependency parsers
(Jason Narad), coreference (Joseph Frazee), CCG parser (Graeme Gange),
and a first order resolution theorem prover (Dan Garrette). This
release was more collaborative than any that have come before, with
commits from 14 developers, plus dozens of contributions and
suggestions from others.
[Note that this release has a couple of installation issues: on
MSWindows, install the corpora first, and click 'no' if asked to
overwrite any files while unzipping nltk_data.zip; on Mac OSX if the
NLTK installer is unsuccessful do "cd /tmp/nltk-installer; sudo python
