Conclusions on <strong>Anaphora</strong> <strong>Resolution</strong> in Written Text• it is useful to train a separate classifier for each NP form;• we seem to be missing something with respect to defNP resolution:world/domain knowledge?• resolution of proper names is ok;• task of pronoun resolution in written text seems to be solved;• from the Co-Training experiments, we conclude that the amount of trainingdata required is surprisingly low.
