Title Never Look Back: An Alternative to Centering
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 1998

I propose a model for determining the hearer's at- tentional state which depends solely on a list of salient discourse entities (S-list). The ordering among the elements of the S-list covers also the function of the backward-looking center in the cen- tering model. The ranking criteria for the S-list are based on the distinction between hearer-old and hearer-new discourse entities and incorporate pref- erences for inter- and intra-sentential anaphora. The model is the basis for an algorithm which operates incrementally, word by word.
