Hybrid rule-based algorithm for coreference resolution
Heming Shou, Hai Yan Zhao · 2012
This paper describes our coreference resolution system for the CoNLL-2012 shared task. Our system is based on the Stanford’s dcoref deterministic system which applies multiple sieves with the order from high precision to low precision to generate coreference chains. We introduce the newly added constraints and sieves and discuss the improvement on the o-riginal system. We evaluate the system using OntoNotes data set and report our results of average F-score 58.25 in the closed track. 1
