Argumentation-based negotiation (ABN) is a prevailing approach
for automated negotiation. It is based on the exchange of arguments that
allow an agent to acquire additional information about the other agents and
the particular circumstances of the negotiation, and can be used for attacking
or justifying offers. This is an important element in resolving conflicts
that very often are due to the assumptions agents have made when making
decisions and which may be found to be false in the course of the negotiation.
Argumentation-based negotiation can be characterized in terms of three main
topics, namely a) the reasoning mechanisms the agents use for negotiating
and which are based on argumentation, b) the protocols the agents use for
conveying arguments and offers and, c) the strategies that determine their
choices at each step of the negotiation. This chapter presents argumentationbased
negotiation by discussing representative works dealing with these three
topics.
