[Corpora-List] Penn Treebank annotated with chunks

[Steven Bird]

Aleksandar,

The "tagged" section of Penn Treebank has chunks marked with brackets, e.g.:

[ Pierre/NNP Vinken/NNP ]
,/,
[ 61/CD years/NNS ]
old/JJ ,/, will/MD join/VB
[ the/DT board/NN ]
as/IN
[ a/DT nonexecutive/JJ director/NN Nov./NNP 29/CD ]
./.

The NLTK corpus readers give access to some chunked corpora:
http://nltk.googlecode.com/svn/trunk/doc/howto/corpus.html#chunked-corpora

NLTK doesn't give an interface to the chunked version of the treebank
data, but it could be added if there was interest in this.
