Traditionally, coreference resolution is done by mining the reference relationships be- tween NP pairs. However, an individual NP usually lacks adequate description informa- tion of its referred entity. In this paper, we propose a supervised learning-based ap- proach which does coreference resolution by exploring the relationships between NPs and coreferential clusters. Compared with indi- vidual NPs, coreferential clusters could pro- vide richer information of the entities for bet- ter rules learning and reference determina- tion. The evaluation done on MEDLINE data set shows that our approach outper- forms the baseline NP-NP based approach in both recall and precision.
