Supporting and representing the group decision-making process is a
complex task that requires very specific characteristics. The current existing argumentation
models cannot make good use of all the advantages inherent to
group decision-making. There is no monitoring of the process or the possibility
to provide dynamism to it. These issues can compromise the success of Group
Decision Support Systems if those systems are not able to provide freedom and
all necessary mechanisms to the decision-maker. We investigate the use of argumentation
in a completely new perspective that will allow for a mutual understanding
between agents and decision-makers. Besides this, our proposal allows
to define an agent not only according to the preferences of the decision-maker
but also according to his interests towards the decision-making process. We show
that our definition respects the requirements that are essential for groups to interact
without limitations and that can take advantage of those interactions to create
valuable knowledge to support more and better.This work has been supported by COMPETE Programme (operational programme for
