An ontology typically provides a vocabulary that describes a domain of interest and a
specification of the meaning of terms used in the vocabulary. Depending on the precision of
this specification, the notion of ontology encompasses several data/conceptual models,
for example, classifications, database schemas, fully axiomatized theories. Ontologies tend to be put
everywhere. They are viewed as the silver bullet for many applications, such as information
integration, peer-to-peer systems, electronic commerce, semantic web services, social
networks, and so on. They, indeed, are a practical means to conceptualize what is expressed in a
computer format. However, in open or evolving systems, such as the semantic web,
