However, for many reasons, different people will tend to use different ontologies [20] to represent the same domain giving birth to the so-called semantic heterogeneity problem. In literature, different types of heterogeneity have been identified, mainly split in the following classes [1]:Syntactic heterogeneity: differences at the language level such as the exploitation of knowledge representation formalisms but the meaning is the same;
