ACL ID W11-1917
Title Coreference Resolution with Loose Transitivity Constraints
Venue International Conference on Computational Natural Language Learning
Session shared task
Year 2011

This paper presents Illinois-Coref, a system for coreference resolution that participated in the CoNLL-2011 shared task. We in- vestigate two inference methods, Best-Link and All-Link, along with their corresponding, pairwise and structured, learning protocols. Within these, we provide a flexible architec- ture for incorporating linguistically-motivated constraints, several of which we developed and integrated. We compare and evaluate the inference approaches and the contribution of constraints, analyze the mistakes of the sys- tem, and discuss the challenges of resolving coreference for the OntoNotes-4.0 data set.
