In this paper we present a novel approach for combining Case-Based Reasoning (CBR) and Argumentation. This approach involves 1) the use of CBR for evaluating the arguments submitted by agents in collaborative decision making dialogs, and 2) the use of Argument Schemes and Critical Questions to organize the CBR memory space. The former involves use of past(More)
In this paper we present the argument-based model proCLAIM, intended to provide a setting for heterogeneous agents to deliberate over safety critical actions. To achieve this purpose proCLAIM features a Mediator Agent with three main tasks: (1) guiding the participating agents in what their valid dialectical moves are at each stage of the dialogue; (2)(More)
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(More)
Agent-based systems have become an important area of research since the 1990s. They have been applied to a range of domains that are intrinsically complex. Among these, environmental problems are of special concern, given their ample affectation to our societies and everyday quality of life. This report provides a review of agent-based systems applied to(More)
Human-organ transplantation is the only effective therapy for many life-threatening diseases. However, despite an increase in transplant successes, the lack of a concomitant increase in donor organ availability has led to a growing disparity between supply and demand. Much research has thus focused on defining and implementing policies for increasing donor(More)
In this paper we propose a dialogue game for agents to deliberate over a proposed action. The agents’ dialogue moves are defined by a structured set of argument schemes and critical questions (CQs). Thus, a dialogue move is an instantiated scheme (i.e. an argument) or a CQ (i.e. a challenge on the argument instantiated in the scheme). The proposed dialogue(More)
In this paper we describe a human organ selection process in which agents argue over whether a given donor’s organ is viable for transplantation. This process is framed in the CARREL System; an agent-based organization designed to improve the overall transplant process. We formalize an argumentation based framework that enables CARREL agents to construct(More)
In this paper we propose the use of an argument-based model – ProCLAIM – that has the potential to minimize ecological impact of industrial wastewater discharges into water bodies. On the one hand, the diversity and unpredictability of many of industrial wastewater discharges and on the other, the complexity of ecological systems that finally receive the(More)
