outstanding issues in anaphora resolution
Ruslan Mitkov
Instead of defining a total preference ordering , Kibble argues that a partial ordering emerges from the interaction among cohesion ( maintaining the same center ) , salience ( realizing the center as subject ) , and cheapness ( realizing the anticipated center of a following utterance as subject ) . The last years have seen considerable advances in the field of anaphora resolution , but a number of outstanding issues either remain unsolved or need more attention and , as a consequence , represent major challenges to the further development of the field ( Mitkov 2001a ) . A fundamental question that needs further investigation is how far the performance of anaphora resolution algorithms can go and what the limitations of knowledge-poor methods are .
