Today, semantic web is playing a key role in the intelligent retrieval of information. It is the new-generation Web that tries to represent information such that it can be used by machines not just for display purposes, but for automation, integration and reuse across applications. It allows the representation and exchange of information in a meaningful way. Ontologies form the backbone of the semantic Web; they allow machine understanding of information through the links between the information resources and the terms in the ontologies.
