C4I Center Seminar Series:
An Ontological Inference Driven Interactive Voice Recognition System

Mohammad Ababneh and Duminda Wijesekera of the C4I Center present
“An Ontological Inference Driven Interactive
Voice Recognition System”

Someone seeking entry to an access controlled facility or through a border control point may face an in-person interview. Questions that may be asked in such an interview may depend on the context and vary in detail. One of the issues that interviewers face is to ask relevant questions that would enable them to either accept or reject entrance. Repeating questions asked at entry point interviews may render them useless because most interviewees may come prepared to answer common questions. As a solution, we present an interactive voice response system that can generate a random set of questions that are contextually relevant, of the appropriate level of difficulty and not repeated in successive question answer sessions. Furthermore, our system will have the ability to limit the number of questions based on the available time, degree of difficulty of generated questions or the desired subject concentration. Our solution uses Item Response Theory to select questions from a large item bank generated by inferences over multiple distributed ontologies. This work will be presented at STIDS 2013.

Mohammad Ababneh is a doctoral candidate in Information Technology at the Volgenau School of Engineering, George Mason University, Fairfax, VA. He is working with his advisor, Professor Duminda Wijesekera on “Policy and Ontology Based Interactive Voice Response System for Access Control”. His research interests include information security and assurance, network security, command and control, semantic web and systems integration. He holds Master degrees with distinction in Computer Science and Information Technology Management from the Naval Post Graduate School, Monterey, CA.

Duminda Wijesekera is a professor in the Computer Science Department at George Mason University and a Visiting Research Scientist at the National Institute for Standards and Technology. His main research area is information security and its applications. His current research projects span logical models of security policies, safety and security of wireless controlled transport systems, security of healthcare applications and financial crime. Prior to George Mason, he was at Honeywell’s Military Avionics and Space Systems divisions in providing real-time systems support for airborne and space-borne applications. He holds PhDs from Cornell University and the University of Minnesota.
