We give an analysis of ellipsis resolution in terms of a straightforward discourse copying algorithm that correctly predicts a wide range of phenomena. The treat- ment does not suffer from problems inher- ent in identity-of-relations analyses. Fur- thermore, in contrast to the approach of Dalrymple et al. [1991], the treatment di- rectly encodes the intuitive distinction be- tween full NPs and the referential elements that corefer with them through what we term role linking. The correct predictions for several problematic examples of ellip- sis naturally result. Finally, the analysis extends directly to other discourse copying phenomena.
