Last Friday I was at the London Argumentation Forum 2011, where (mostly) students presented their argumentation-related work. Here are the sheets of my presentation, if you’re interested.

Where agents are employed to cooperatively solve tasks, communication becomes a critical factor. Argumentation-based models have been proposed to support the required dialogues. Improved efficiency and effectiveness of these dialogues have been the justification for using argumentation. However, as of yet there is little work done on making the benefits of arguing versus non-arguing models clear. Our current research focusses on empirically evaluating argumentation-based dialogues, specifically for deliberation, by quantifying the desirable properties for such dialogues and comparing arguing and non-arguing strategies in a multi-agent simulation.

Thanks to Sanjay and Francesca for the organisation and COST for the covered travel expenses!

A FORMAL FRAMEWORK FOR DELIBERATION DIALOGUES

Back from ArgMAS in Toronto; a nice and interesting trip! I have put online both my paper and presentation for anyone to download it.

ARGMAS 2010: FRAMEWORK FOR DELIBERATION DIALOGUES

On the 10th of May, I will be at the Argumentation in Multi-Agent Systems (ArgMAS) workshop, which is held as part of this year’s Agents and Multi-Agent Systems (AAMAS) conference. I will present the work from my accepted paper ‘A Formal Argumentation Framework for Deliberation Dialogues’, which was written together with Henry Prakken, Gerard Vreeswijk and John-Jules Meyer.

Agents engage in deliberation dialogues to collectively decide on a course of action. To solve conflicts of opinion that arise, they can question claims and supply arguments. Existing models fail to capture the interplay between the provided arguments as well as successively selecting a winner from the proposals. This paper introduces a general framework for agent deliberation dialogues that uses an explicit reply structure to produce coherent dialogues, guides in outcome selection and provide pointers for agent strategies.

Looking forward to going to Toronto, Canada!
