Author(s)
John S. Garofolo
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Measurements in Support of Research Accomplishments

July 1, 2000
Author(s)
D S. Pallett, John S. Garofolo, Jonathan G. Fiscus
This paper reviews the role provided by the National Institute of Standards and Technology (NIST) in the development of measurements in support of broadcast news-based technologies. The focus of these measurements was initially on specifying the word error

ATLAS: A Flexible and Extensible Architecture for Linguistic Annotation

May 1, 2000
Author(s)
S Bird, D Day, John S. Garofolo, J Henderson, Christophe Laprun, M Liberman
We describe a formal model for annotating linguistic artifacts, from which we derive an application programming interface (API) to a suite of tools for manipulating these annotations. The abstract logical model provides for a range of storage formats and

The TREC Spoken Document Retrieval Track: A Success Story

April 1, 2000
Author(s)
John S. Garofolo, C G. Auzanne, Ellen M. Voorhees
This paper describes work within the NIST Text REtrieval Conference (TREC) over the last three years in designing and implementing evaluations of Spoken Document Retrieval (SDR) technology within a broadcast news domain. SDR involves the search and

Automatic Language Model Adapation for Spoken Document Retrieval

January 1, 2000
Author(s)
C G. Auzanne, John S. Garofolo, Jonathan G. Fiscus, W M. Fisher
This paper describes experiments implemented at NIST in adapting language models over time to improve recognition of broadcast news recorded over many months. These experiments were designed specifically to improve the utility of automatically generated

TREC-6 1997 Spoken Document Retrieval Track Overview and Results

October 25, 1999
Author(s)
John S. Garofolo, Ellen M. Voorhees, Vincent M. Stanford, K Sparck Jones
This paper describes the 1997 TREC-6 Spoken Document Retrieval (SDR) Track which implemented a first evaluation of retrieval of broadcast news excerpts using a combination of automatic speech recognition and information retrieval technologies. The

1998 TREC-7 Spoken Document Retrieval Track Overview and Results

October 26, 1998
Author(s)
John S. Garofolo, Ellen M. Voorhees, C G. Auzanne, Vincent M. Stanford, B A. Lund
This paper describes the 1998 TREC-7 Spoken Document Retrieval (SDR) Track which implemented an evaluation of retrieval of broadcast news excerpts using a combination of automatic speech recognition and information retrieval technologies. The motivations

Framework for Performance Evaluation of Face, Text, and Vehicle Detection and Tracking in Video: Data, Metrics, and Protocol

Author(s)
Rangachar Kasturi, D Goldgof, K Soundararajan, V Manohar, M Boonstra, V Korzhova, J Zhang, Rachel J. Bowers, John S. Garofolo
Common benchmark datasets, standardized performance metrics, and baseline algorithms have demonstrated considerable impact on research and development in a variety of application domains. These resources provide both consumers and developers of technology
