An Introduction to Uncertainty in Ontology Mapping (Part 1)

Paolo Besana

In these two talks, I will explain why I believe that ontology mapping involves uncertainty, the methods that are available for representing and handling uncertainty, and how these methods may be applied to ontology mapping.   These talks are given with the purpose of trying to clarify my own ideas in the subject, in the hope that this will help me to identify the proper method for my current research.   In this first part, I will give a description of what uncertainty is and I will present some quantitative methods for representing uncertainty.  In particular, I will describe the probabilistic approach, Bayesian networks, the Certainty Factor, and Dempster-Shafer.  In the second part, I will briefly overview some qualitative methods, and I will explain how the methods can be applied to ontology mapping.
