This book provides a detailed overview of Regulus, an open-source toolkit for building and
compiling grammars for spoken dialog systems, which has been used for a number of …

The theoretical richness, formal rigor and computational versatility of Head-driven Phrase
Structure Grammar (HPSG) preclude any kind of in-depth coverage of its content within the …

An efficient parsing technique for HPSG is presented. Recent research has shown that
supertagging is a key technology to improve both the speed and accuracy of lexicalized …

We report on significant performance gains (factor> 5.5 with ceiling effect, 14.7 without) that
can be achieved by a redesign of the implementation of verbmovement in an HPSG for …

One major obstacle to the efficient processing of large wide coverage grammars in
unification-based grammatical frameworks such as HPSG is the time and space cost of the …

In this paper, we propose a rule-based method to improve efficiency in bottom-up chart
generation with GG, an open-source reversible large-scale HPSG for German. Following an …

This article presents an HPSG parser using a technique called CFG filtering. The parser
predicts possible parse trees using a CFG generated automatically from a given HPSG …

Plug and Play is an increasingly important concept in system and network architectures. We
introduce and describe a spoken language dialogue system architecture which supports …

This paper describes the successful metamorphosis of PAGE from a string-based grammar
development system to an efficient run time system, operating on word hypotheses graphs …

This paper presents a minimal enumerative approach to the problem of compiling typed
unification grammars into CFG language models, a prototype implementation and results of …
