Following the last "reflection" talk, I will be giving an overview of the Symposium on Argument and Computation http://www.csd.abdn.ac.uk/~tnorman/sac/ which I attended recently. The purpose of this meeting was to bring together both the philosophical and computational perspective on argumentation, producing a handbook that will serve as a roadmap for research in this interdisciplinary topic. It was a very intensive and productive event, and amazingly we've managed to write such a handbook. I'll be talking about the way the symposium was organised, and what sorts of things we've addressed in the papers.
