The book will appeal to scholars and advanced students of morphology, syntax,
computational linguistics and natural language processing (NLP). It provides a critical and …

This document describes a sizable grammar of English written in the TAG formalism and
implemented for use with the XTAG system. This report and the grammar described herein …

Much recent research on the design of natural language lexicons has made use of
nonmonotonic inheritance networks as originally developed for general knowledge …

In this article, we introduce eXtensible MetaGrammar (XMG), a framework for specifying tree-
based grammars such as Feature-Based Lexicalized Tree-Adjoining Grammars (FB-LTAG) …

Abstract Lexicalized Tree Adjoining Grammars have proved useful for NLP. However,
numerous redundancy problems face LTAGs developers, as highlighted by Vijay-Shanker …

Paraphrase, as a general concept, is a very mutable thing; at one extreme, paraphrase is the
relation between units of text with identical meanings, as under the …

Grammars are valuable resources for natural language processing. We divide the process of
grammar development into three tasks: selecting a formalism, defining the prototypes, and …

We survey a sequence of results relating model-theoretic and language-theoreticdefinability
over an infinite hierarchy of multi-dimensional tree-like structures and explore their …

We explore the use of weak monadic second-order languages over structures of varying
dimension as specification languages for grammars and automata, focusing, in particular, on …

In contrast to LFG and HPSG, there is to date no large scale Tree Adjoining Grammar (TAG)
equiped with a compositional semantics. In this paper, we report on the integration of a …
