Abstract:

This report is a compilation of papers by the PATR group in the Artificial Intelligence Center at SRI International reporting on on-going research on both practical and theoretical issues concerning grammar formalisms. The current formalism being simultaneously designed, implemented and used by the group, PATR-II, is based on unification of directed-graph structures. Unification is thus a theme both of our research, and of the papers reproduced in this volume. These papers provide an overview of the design of PATR-II Chapter 1, a discussion of the use of disjunction and negation in unification-based feature systems Chapter 2, and a theoretical framework for unification-based grammar formalisms which is founded on the domain-theoretic techniques of Dana Scott Chapter 3. All three chapters are versions of papers presented at the Tenth International Conference on Computational Linguistics at Stanford University, Stanford, California during July 2 through 7, 1984.
