The Air Travel Information System (ATIS) domain serves as the common evaluation task for ARPA"spoken language system developers. 1 To support this task, the Multi-Site ATIS Data COllection Working group (MADCOW) coordinates data collection activities. This paper describes recent MADCOW activities. In particular, this paper describes the migration of the(More)
This paper describes the SDC PUNDIT, (Prolog UNDerstands Integrated Text), system for processing natura l language messages. 1 PUNDIT, written in Prolog, is a highly modular system consisting of distinct syntactic, semantic and pragmatics components. Each component draws on one or more sets of data, including a lexicon, a broad-coverage grammar of EngLish,(More)
Introduct ion The DARPA Spoken Language communi ty has just completed the first trial evaluation of spontaneous query/response pairs in the Air Travel (ATIS) domain. 1 Our goal has been to find a methodology for evaluating correct responses to user queries. To this end, we agreed, for the first trial evaluation, to constrain the problem in several ways: D a(More)
The Air Travel Information System (ATIS) domain serves as the common task for DARPA spoken language system research and development. The approaches and results possible in this rapidly growing area are structured by available corpora, annotations of that data, and evaluation methods. Coordination of this crucial infrastructure is the charter of the(More)
This paper describes the use of focusing in the PUNDIT text processing system. 1 Focusing, as discussed by [Sidner1979] (as well as the closely related concept of centering, as discussed by [Grosz1983] ), provides a powerful tool for pronoun resolution. However, its range of application is actually much more general, in that it can be used for several(More)
UNLABELLED It has been known to the public that high frequency of false and/or unnecessary alarms from patient monitoring devices causes "alarm fatigue" in critical care. But little is known about the impact to care on the less acute patients located outside the critical care areas, such as the traditional medical/surgical (med/surg) floor. METHODS As(More)
This paper describes an analysis of telegraphic fragments as regular structures (not errors) handled by rn~n~nal extensions to a system designed for processing the s tandard language. The modular approach which has been implemented in the Unlsys natural language processing system PUNDIT is based on a division of labor in which syntax regulates the(More)
Introduction This paper presents the Unisys Spoken Language System, as applied to the Air Travel Planning (ATIS) domain. 1 This domain provides a rich source of interactive dialog, and has been chosen as a common application task for the development and evaluation of spoken language understanding systems. The Unisys approach to developing a spoken language(More)
Introduct ion This paper describes our results on a spoken language application for finding directions. The spoken language system consists of the MIT SUMMIT speech recognition system ([20]) loosely coupled to the UNISYS PUNDIT language understanding system ([9]) with SUMMIT providing the top N candidates (based on acoustic score) to the P U N D I T system.(More)
