Defeasible reasoning with e-contracts

Abstract

We propose a mapping from a contract representation in Event Calculus to Default Logic. The resulting representation allows for defeasible reasoning with e-contracts, which is useful in order to determine the normative state of a business exchange in the presence of incomplete or inaccurate knowledge. More importantly, we may use this representation in Default Logic coupled with priorities, in order to manage normative conflicts dynamically. © 2006 IEEE.
