Jérôme Euzenat, Evaluating ontology alignment methods, in: Proc. Dagstuhl seminar on Semantic interoperability and integration, Wadern (DE), (Yannis Kalfoglou, Marco Schorlemmer, Amit Sheth, Steffen Staab, Michael Uschold (eds), Semantic interoperability and integration, (04391), 2005), 2005
Many different methods have been designed for aligning ontologies. These methods use such different techniques that they can hardly be compared theoretically. Hence, it is necessary to compare them on common tests. We present two initiatives that led to the definition and the performance of the evaluation of ontology alignments during 2004. We draw lessons from these two experiments and discuss future improvements.
