A Methodology for the Generation of Multi-Agent Argumentation Dialogue Scenarios Eric M. Kok, John-Jules Ch. Meyer, Herre van Oostendorp, Henry Prakken, and Gerard A. W. Vreeswijk Increasingly research into the uses of argumentation in multi-agent dialogues takes an experimental approach. Such studies explore how agents can successfully employ argumentation besides the best and worst case situations of formal analysis. While a vital part in these experiments is influenced by the scenarios from which dialogues are generated, there is very little research on how these can be generated in a meaningful way, respecting the characteristics of the underlying dialogue problem. This paper proposes, by means of an example system for deliberation dialogues, a methodology for the construction and evaluation of a scenario generation process. It is shown how scenarios can accomodate argumentation with structured arguments and how it is tested whether the generated scenarios are interesting for experimentation.
