<div>Greetings,</div>
<div> </div>
<div>I am looking for coreference annotation corpora based on the Penn TreeBank. I am aware of the BBN corpus:</div>
<div> </div>

<div> </div>
<div>...as well as the study by Poesio and Vieira ("A Corpus-based Investigation of Definite<br>Description Use", 1998).</div>
<div> </div>
<div>Is anyone aware of any other large-scale coreference annotation efforts for the Wall Street Journal portion of the Penn TreeBank?</div>
<div> </div>
<div>Cheers,</div>
