Agents embedded in open, dynamic and decentralized environments adopt different ontologies to describe their domain of discourse. Yet, agents have no prior knowledge of the other agents with whom they will interact. Therefore, a consistent and compatible communication relies on the agents' ability to reconcile in run-time the vocabulary used in their ontologies whose result is a set of correspondences. Since each party might have its own perspective about what are the best correspondences, conflicts arise. To address such conflicts, it is envisaged as a suitable approach that agents adopt the generic argument-based negotiation process presented in [1]. A critical issue of that process concerns the argument generation process according to the argumentation framework that it relies on. In this paper we propose an automatic process to generate arguments regarding the ontologies reconciliation through semantic interpretations of third party generated correspondences.
