In this paper, we present the WIRE system for human intelligence reporting and discuss challenges of deploying spoken language understanding systems for the military, particularly for dismounted warfighters. Using the PARADISE evaluation paradigm, we show that performance models derived using standard metrics can account for 68% of the variance of User Satisfaction. We discuss the implication o...
Evaluation is critical in offering feedback on progress_toboth developers andpotential consumers of NLG technology. However, evaluation has thus far not been as well-established in NLG as it has become in NLU. This panel will discuss evaluation methods and resources. It is aimed at building a better understanding of NLG evaluation methods, and hopefully arriving at steps to facilitate future ev...
Title generation is a complex task involving both natural language understanding and natural language synthesis. In this paper, we propose a new probabilistic model for title generation. Different from the previous statistical models for title generation, which treat title generation as a generation process that converts the ‘document representation’ of information directly into a ‘title repres...
We present a system, called IMMIGRANT, which learns rules about the grammar of a second language from instructions. We explore the implications of this task on the representation of linguistic knowledge in a natural language understanding system. We conclude that the internal representation of linguistic knowledge used in IMMIGRANT, which is unification-based, is more amenable to language learn...
The LUNA corpus is a multi-lingual, multidomain spoken dialogue corpus currently under development that will be used to develop a robust natural spoken language understanding toolkit for multilingual dialogue services. The LUNA corpus will be annotated at multiple levels to include annotations of syntactic, semantic, and discourse information; specialized annotation tools will be used for the a...
Three information extraction system evaluations using Tipster data were conducted in the context of Phase 1 of the Tipster Text program. Interim evaluations were conducted in September, 1992, and February, 1993; the final evaluation was conducted in July, 1993. The final evaluation included not only the Tipster-supported inform~on extraction contractors but thirteen other participants as well. ...
One of the first steps in an SLU system usually is the extraction of flat concepts. Within this paper, we present five methods for concept tagging and give experimental results on the state-of-the-art MEDIA corpus for both, manual transcriptions (REF) and ASR input (ASR). Compared to previous publications, some single systems could be improved and the ASR results are presented for the first tim...
Common evaluations have grown to be a major component of all the ARPA Human Language Technology programs. In the written language community, the largest evaluation program has been the series of Message Understanding Conferences, which began in 1987 [2,3]. These evaluations have focussed on the task of analyzing text and automatically filling templates describing certain classes of events. Thes...
Objective Our goal is to improve the technology for retrieving passages , extracting specific facts, and creating formatted data bases from large text collections. In particular, we are concerned with developing techniques for automatically training language processing systems to the syntax and semantics of particular domains and types of text in order to improve system performance. Approach Im...
Information extraction research at the University of Massachusetts is based on portable, trainable language processing components. Some components are more effective than others, some have been under development longer than others, but in all cases, we are working to eliminate manual knowledge engineering. Although UMass has participated in previous MUC evaluations, all of our information extra...
