Exploiting Rough Argumentation in an Online Dispute Resolution Mediator
Online dispute resolution is becoming the main method when dealing with a conflict in e-commerce. Our framework exploits the argumentation semantics of defeasible logic, shown to be a suitable choice for legal reasoning. We introduce the rough set theory within defeasible logic for handling the gradual information revealed in a legal dispute. The rough sets are being used in the generation of defeasible theories from available cases, but also in the inference rules required for the argumentation process. The framework can cover both aspects of the law: case based reasoning and legal syllogism.
