Knowledge Reposiory as Entity Similarity Computing Enabler

With the adoption of Semantic Web technologies, knowledge based applications are nowadays common. They rely on the use of numerous and varied knowledge organization systems. This raises the problem of the interoperability of the underlying models in particular for data integration purpose. We present in this paper an approach based on an ontology server and providing functionalities including ontology matching and change detection. The evaluation of the matching approach using standard measure of recall/precision/F-measure shows results which outperform in certain contexts current available systems which are able to process large data set.
