J. Euzenat and N. Noy:  Semantic Interoperability ISWC, 2008.
Abstract: In the same way that the Web is composed of heterogeneous resources the Semantic Web is composed of heterogeneous ontologies. In this session Jerome and Natasha will discuss what interoperability means at the semantic level. Additionally, they will outline different techniques which can be used to address this problem. At the end of this session attendees will understand the notions and issues underlying semantic interoperability.

P. Shvaiko:  Ontology Matching SWAP, 2006.
Abstract: Matching is a key operation for enabling the Semantic Web since it takes as input ontologies, each consisting of a set of discrete entities (e.g., tables, XML elements, classes, properties), and determines as output the relationships (e.g., equivalence, subsumption) holding between those entities. In this tutorial we introduce, via examples, the ontology matching problem and its application domains. We provide a detailed discussion of the techniques used for ontology matching with the help of a classification of matching approaches. We overview state of the art systems in light of the classification presented, indicating which part of the solution space they cover. Finally, we outline future challenges in the field of ontology matching.

N. Noy:  Ontology Mapping and Alignment SSSW, 2005.
Abstract: Ontology mapping, alignment, and translation has been an active research component of the general research on semantic integration and interoperability. In this talk, we discuss types of heterogeneity between ontologies, classify methods for discovering mappings between both ontology concepts and data, and talk about various tasks where mappings are used.
