[Corpora-List] English treebank

[Ulrik Sandborg-Petersen]

Hi Rich,

A subset of the Penn Treebank is freely available under a Creative 
Commons license as part of the NLTK corpus set:

You might also want to purchase the BLLIP corpus from the LDC, as it is 
cheaper than the Penn Treebank, and is an automatic parsing of the 
1987-1989 stories from the Wall Street Journal also used for the Penn 
Treebank. It might suit your needs.
