Abstract

We describe an implementation in Carpenter's typed feature formalism, ALE, of a discourse gram~ mar of the kind proposed by Scha, Polanyi, et al. We examine their method for resolving parallelism-dependent anaphora and show that there is a coherent feature-structural rendition of this type of grammar which uses the operations of priority union and generalization. We describe an augmentation of the ^LE system to encompass these operations and we show that an appropriate choice of definition for priority union gives the desired multiple output for examples of Vl-ellipsis which exhibit a strict/sloppy ambiguity.
