This lecture will be an introduction to the theory of judgment aggregation (JA). JA deals with the problem of combining the views of several individual agents regarding the truth of a number of propositions, expressed in the language of logic, into a single such view that appropriately reflects the stance of the group as a whole. Applications of JA range from aggregating the opinions of several judges in a court of law into a single legal opinion, all the way to aggregating information received from several autonomous software agents in the context of distributed computing systems.
Ulle Endriss is Professor of AI and Collective Decision Making at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam. His research concerns the use of formal methods in artificial intelligence, specifically in multiagent systems and knowledge representation. In recent years, Endriss has mostly focused on problems at the interface of artificial intelligence with economics and political science, and much of this work falls under the heading of computational social choice. Specific research topics in this domain include preference modelling, voting theory, judgment aggregation, fair division, negotiation and auctions. He has also worked on agent communication languages, automated reasoning, abduction, modal and temporal logics, and software tools for teaching logic.
