Title: Aggregation of Abstract Argumentation Frameworks
Date: Tuesday 20 June 2017
Time: 16:00
Location: Room F1.15, Science Park 107, Amsterdam


An abstract argumentation framework can be used to model the argumentative stance of an agent at a high level of abstraction, by indicating for every pair of arguments that is being considered in a debate whether the first attacks the second. When modelling a group of agents engaged in a debate, we may wish to aggregate their individual argumentation frameworks to obtain a single such framework that reflects the consensus of the group. Even when agents disagree on many details, there may well be high-level agreement on important semantic properties, such as the acceptability of a given argument. Using techniques from social choice theory, I will analyse under what circumstances such semantic properties agreed upon by the individual agents can be preserved under aggregation. This is joint work with Ulle Endriss.
