• Assumption-based reasoning in dynamic normative agent systems 

      Giannikis, G. K.; Daskalopulu, A. (2010)
      In this paper we address dynamic assumption-based reasoning in open agent systems, where, unavoidably, agents have incomplete knowledge about their environment and about other agents. The interactions among agents in such ...
    • Defeasible reasoning with e-contracts 

      Giannikis, G. K.; Daskalopulu, A. (2007)
      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 ...
