The CoNLL-2012 shared task is an extension of the last year?s coreference task. We partici- pated in the closed track of the shared tasks in both years. In this paper, we present the im- provements of Illinois-Coref system from last year. We focus on improving mention detec- tion and pronoun coreference resolution, and present a new learning protocol. These new strategies boost the performance of the system by 5% MUC F1, 0.8% BCUB F1, and 1.7% CEAF F1 on the OntoNotes-5.0 development set.
