This paper describes our entry to the 2011 CoNLL closed task (Pradhan et al., 2011) on modeling un- restricted coreference in OntoNotes. Our system is based on the Reconcile coreference resolution re- search platform. Reconcile is a general software in- frastructure for the development of learning-based noun phrase (NP) coreference resolution systems. Our entry for the CoNLL closed task is a configura- tion of Reconcile intended to do well on OntoNotes data. This paper describes our configuration of Rec- oncile as well as the changes that we had to imple- ment to integrate with the OntoNotes task definition and data formats. We also present and discuss the performance of our system under different testing conditions on a withheld validation set.
