Agreeing What to Do

When deliberating about what to do, an autonomous agent must generate and consider the relative pros and cons of the different options. The situation becomes even more complicated when an agent is involved in a joint deliberation, as each agent will have its own preferred outcome which may change as new information is received from the other agents involved in the deliberation. We present an argumentation-based dialogue system that allows agents to come to an agreement on how to act in order to achieve a joint goal. The dialogue strategy that we define ensures that any agreement reached is acceptable to each agent, but does not necessarily demand that the agents resolve or share their differing preferences. We give properties of our system and discuss possible extensions. ACM Category: I.2.11 Multiagent systems. General terms: Theory.
