English News Text Treebank: Penn Treebank Revised was developed by the Linguistic Data Consortium (LDC) with funding through a gift from Google Inc. It consists of a combination of automated and manual revisions of the Penn Treebank annotation of Wall Street Journal (WSJ) stories. The data is comprised of 1,203,648 word-level tokens in 49,191 sentence-level tokens -- in all 2,312 of the original Penn Treebank WSJ files.
This release includes revised tokenization, part-of-speech, and syntactic treebank annotation intended to bring the full WSJ treebank section into compliance with the agreed-upon policies and updates implemented for current English treebank annotation specifications at LDC. Examples include English Web Treebank (LDC2012T13), OntoNotes (LDC2013T19), and English translation treebanks such as English Translation Treebank: An-Nahar Newswire (LDC2012T02). English Treebank Supplemental Guidelines are included in this release.
