Pairwise coreference resolution models must merge pairwise coreference decisions to gen- erate final outputs. Traditional merging meth- ods adopt different strategies such as the best- first method and enforcing the transitivity con- straint, but most of these methods are used independently of the pairwise learning meth- ods as an isolated inference procedure at the end. We propose a joint learning model which combines pairwise classification and mention clustering with Markov logic. Experimen- tal results show that our joint learning sys- tem outperforms independent learning sys- tems. Our system gives a better performance than all the learning-based systems from the CoNLL-2011 shared task on the same dataset. Compared with the best system from CoNLL- 2011, which employs a rule-based meth...
