A Conditional Logic-Based Argumentation Framework

The goal of this paper is twofold. First, a logic-based argumentation framework is introduced in the context of conditional logic, as conditional logic is often regarded as an appealing setting for knowledge representation and reasoning. Second, a concept of conditional contrariety is defined that covers usual inconsistency-based conflicts and puts in light a specific form of conflicts that often occurs in real-life: when an agent asserts an If then rule, it can be argued that additional conditions are actually needed to derive the conclusion.
