Abstract

An important field of application of intelligent logical agents, where rationality plays a main role, is that of automated negotiation. Our work is related to the use of argumentation in the field of negotiation. In particular, we are interested in contract violations, and in the construction of justifications to motivate the violation itself and recover if possible the contract on modified conditions. We propose a temporal modal logic language able to support and depict the arguments/justification used in dialectical disputes and we consider suitable algorithms and mechanisms to introduce and manage justifications.
