Abstract: In this paper, we present an ontology mediation solution based on the methods frequently usedin Formal Concept Analysis. Our approach of mediation is based on the existence of instancesassociated to two source ontologies, then we can generate concepts in a new ontology if and onlyif they share the same extent. Hence our approach creates a merged ontology which capturesthe knowledge of these two source ontologies. The main contributions of this work are (i) toenable the creation of concepts not originally in the source ontologies, (ii) to propose a solutionto label these emerging concepts and finally (iii) to optimize the resulting ontology byeliminating redundant or non pertinent concepts. Another contribution of this work is toemphasize that several forms of mediated ontology can be defined based on the relaxation ofcertain criteria produced from our method. The solution that we propose for tackling theseissues is an automatic solution, meaning that it does not require the intervention of the end-user, excepting for the definition of the common set of ontology instances.
