Agent-based Ontology Alignment Negotiation processes aims to generate an alignment through the interaction of two or more agents. When these agents exploit different matching services they can reach incompatible alignments, giving rise to conflicts hence the need to engage in a negotiation to achieve consensus. This consensus is sounder as more conflicts are correctly solved. In this paper, a Relaxation-based approach for Agent-based Ontology Matching Negotiation is explored and compared with the MbA/FDO argument-based approach. The limitations of the original Relaxation approach are addressed and modifications are proposed that increase the circumstances under which conflict resolution may occur, thus generating sounder alignments.

With the increasing popularity of the Semantic Web, more and more data models are being published daily in the form of ontologies, micro-formats or micro-data. This increase in the amount of models and their heterogeneity is becoming a global scale integration problem. We propose a decentralized and scalable multi-agent negotiation process for ontology alignment that exploits an underlying social network communication structure and SNA measures and algorithms.Social network analisys; multi-agent systems; ontology alignment; expert finding

“…lack of quantitative or opinion factors) it is envisaged as a suitable approach that agents adopt the generic and domainindependent argument-based negotiation process presented in [1], which relies on the Extensible Argumentation Framework (EAF) [1], [7], to address conflicts about correspondences. For that, the EAF Instantiation phase which concerns the arguments generation is seen as a critical issue.…”

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.
