Title: An introduction to computational argumentation and ranking based argumentation semantics
Abstract: Argumentation is a process of constructing arguments as well as attacks and supports between them. In the first part of my talk, I present some of the basic notions from the computational argumentation theory. I start by showing examples of arguments and discussing some applications. I survey different extension-based acceptability semantics used in argumentation and the principles they should satisfy. The second part of the talk is devoted to ranking-based semantics and the principles they should satisfy. We examine existing principles and study the links between them. We also present some of the existing ranking-based semantics and illustrate their behavior on examples. We conclude by showing which semantics satisfies which of the aforementioned principles.
Bio: Srdjan Vesic is a CNRS scientific researcher at the CRIL laboratory in Lens (France) since 2013. From 2011 to 2013, he was a post-doctoral researcher at the University of Luxembourg, where he held an ERCIM postdoctoral fellowship and an FNR AFR fellowship, both co-funded by Marie-Curie Actions. Before that, he received his PhD from IRIT – University of Toulouse in 2011. His research interests include argumentation theory, measuring/decreasing inconsistency, e-democracy and computational social choice. Srdjan has published fifty peer-reviewed papers. His publication record includes Journal of Artificial Intelligence Research, Social Choice and Welfare, International Journal of Approximate Reasoning, as well as conferences like IJCAI, AAAI, ECAI and KR. He was a keynote speaker at GKR 2017@IJCAI and gave a tutorial at KR 2018. He has served on the program committee in several AI conferences (IJCAI, AAMAS, ECAI…). He is also a reviewer for Artificial Intelligence Journal, Journal of Artificial Intelligence Research and Artificial Intelligence Review.
