This paper has three aims: (1) to generalize a computational account of the discourse process called CENTERING, (2) to apply this account to discourse processing in Japanese so that it can be used in computational systems for machine translation or language understanding, and (3) to provide some insights on the effect of syntactic factors in Japanese on(More)
In our approach, each elementary structure is systematically associated with a lexical head. These structures specify extended domains of locality (as compared to a context-free grammar) over which constraints can be stated. These constraints either hold within the elementary structure itself or specify what other structures can be composed with a given(More)
The Computational Linguistics Feedback Forum (CLIFF) is a group of students and faculty who gather once a week to discuss the members' current research. As the word "feedback" suggests, the group's purpose is the sharing of ideas. The group also promotes interdisciplinary contacts between researchers who share an interest in Cognitive Science. and many(More)
This paper presents a sizable grammar for English written in the Tree Adjoining grammar (TAG) formalism. The grammar uses a TAG that is both lexicalized (Schabes, Abeillé, Joshi 1988) and feature-based (Vijay-Shankar, Joshi 1988). In this paper, we describe a wide range of phenomena that it covers. A Lexicalized TAG (LTAG) is organized around a lexicon,(More)
i ii About XTAG XTAG is a graphically oriented package that has been developed at the University of Pennsylvania as a tool for writing Tree Adjoining Grammars and for testing parsers for TAG. It is implemented within CLX (Common LISP X Interface) in Common Lisp. The TAG System is an integration of two main tools: a tree manipulation system and a predictive(More)
