Argument Schemes and Critical Questions for Heterogeneous Agents to Argue over the Viability of a Human Organ for Transplantation

In this paper we present a framework in which heterogeneous agents can argue over the viability of a human organ for transplantation. This collaborative decision making process among human and/or software agents is mediated by a software agent that uses argument schemes and critical questions to direct the deliberation, and determines a final evaluation of the given arguments. The proposed model is framed in the CARREL System, an agent-based organization designed to improve the overall transplant process. In particular, we believe that the use of argumentation has the potential to increase the number of human organs that current selection processes make available for transplantation.
