... the non-anaphoric class directly from non-anaphoric training instances whereas the single-step model cannot not use non-anaphoric cases in training. 4 Proposal 4.1 Task decomposition We approach the zero-anaphora ... resolution (AR), in which zero- anaphora is regarded as a subclass of anaphora. In AR, the research trend has been shifting from rule- based approaches (Baldwin, 1995;...
