AIC Seminar Series

Semantic Web applications call for the knowledge base counterparts of hyperlinked documents so that independently created ontology modules can be flexibly linked and reused to meet the needs of specific applications, users, or contexts. We argue that ontology languages and tools should support selective knowledge sharing, accommodate reconciliation of multiple points of view about the world, and provide distributed reasoning services based on well-defined semantics and a sound proof theory. Against this background, this talk will give a brief overview of the techniques provided by Package-based Description Logics on modeling modular and contextualized knowledge bases.

Dr. Jie Bao is a research associate at the Tetherless World Constellation, Rensselaer Polytechnic Institute. He is also a visiting scientist at Raytheon BBN Technologies and was a research affiliate at the Decentralized Information Group, Massachusetts Institute of technology. He was a member of the OWL Working Group at W3C. He received his Ph.D. in computer science from the Iowa State University (ISU) in 2007. His research activities span a variety of topics in Artificial Intelligence and Semantic Web, including description logics, semantic wikis, context modeling, semantic information theory, rule languages, closed world reasoning, policy modeling, semantic data integration, modular ontologies, collaborative ontology building, web privacy protection, neural network and data mining. Dr. Bao has authored more than 50 refereed research papers. He has served on Organizing Committees or Programming Committees of more than 30 international conferences and workshops.
