Coherence-driven argumentation to norm consensus
Sindhu Joseph, Henry Prakken · 2009
In this paper coherence-based models are proposed as an alternative to logic-based BDI and argumentation models for the reasoning of normative agents. A model is provided for how two coherence-based agents can deliberate on how to regulate a domain of interest. First a deductive coher-ence model presented, in which the coherence values are de-rived from the deduction relation of an underlying logic; this makes it possible to identify the reasons for why a proposi-tion is accepted or rejected. Then it is shown how coherence-driven agents can generate candidate norms for deliberation, after which a dialogue protocol for such deliberations is pro-posed. The resulting model is compared to current logic-based argumentation systems for deliberation over action.
