English News Text Treebank: Penn Treebank Revised

<h3>Introduction</h3><br>
<p>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 <a href="../../../LDC99T42">Penn Treebank</a> 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.</p><br>
<h3>Data</h3><br>
<p>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.
