Ontology Formalisms: What is Appropriate for Different Applications?

October 6, 2009
Author(s)
Craig I. Schlenoff
Ontologies can take many forms. There are ontologies that are extremely formal (e.g., using first order logic), and there are ontologies that are much less formally defined (e.g., ontologies in the relational databases or dictionaries). Nonetheless, all of

Evaluating Speech Translation Systems: Applying SCORE to TRANSTAC Technologies

September 29, 2009
Author(s)
Craig I. Schlenoff, Brian A. Weiss, Michelle P. Steves, Gregory A. Sanders, Frederick M. Proctor, Ann M. Virts
The Spoken Language Communication and Translation System for Tactical Use (TRANSTAC) program is a Defense Advanced Research Projects Agency (DARPA) advanced technology research and development program. The goal of the TRANSTAC program is to demonstrate

Fuzzy-Logic-Based Approach for Identifying Objects of Interest in the PRIDE Framework

August 21, 2008
Author(s)
Zeid Kootbally, Craig I. Schlenoff, Rajmohan Madhavan, Sebti Foufou
On-road autonomous navigation of autonomous vehicles requires real--time motion planning in the presence of moving objects. Based on sensed data of moving objects in the environment and the situation it finds itself in, an autonomous vehicle has to plan a

Ontological Perspectives for Autonomy Performance

August 21, 2008

Hui-Min Huang, Elena R. Messina, Tsai Hong Hong, Craig I. Schlenoff
Goals must be assigned for any unmanned system’s (UMS) operation before the system’s autonomous performance can be measured. In this paper, we began to construct an ontology for mission goals that could serve as a template for stating the goal. We apply

Applying Automated Metrics to Speech Translation Dialogs

June 30, 2008
Author(s)
Sherri Condon, Jon Phillips, Christy Doran, John Aberdeen, Dan Parvaz, Beatrice Oshika, Gregory A. Sanders, Craig I. Schlenoff
Over the past five years, the Defense Advanced Research Projects Agency (DARPA) has funded development of speech translation systems for tactical applications. A key component of the research program has been extensive system evaluation, with dual

Performance Evaluation of Speech Translation Systems

Brian A. Weiss, Craig I. Schlenoff, Gregory A. Sanders, Michelle P. Steves, Sherri Condon, Jon Phillips, Dan Parvaz
One of the most challenging tasks for uniformed service personnel serving in foreign countries is effective verbal communication with the local population. To remedy this problem, several companies and academic institutions have been funded to develop

A Brief History of PRIDE

December 28, 2007
Author(s)
Zeid Kootbally, Craig I. Schlenoff, Rajmohan Madhavan
PRIDE (PRediction In Dynamic Environments) is a framework that provides an autonomous vehicle's planning system with information that it needs to perform path planning in the presence of moving objects. The underlying concept is based upon a multi
