Contextual ontology helps in the knowledge-full indexing of documents, providing semantic structure to the document. The named entity and the associated keywords can be a clue to the contextual sense of the documents in the corpus. The proposed technique for the information retrieval creates the ecology of ontology which stores the ontological representation of the crawled documents. Further, the efficiency of ontology based indexing is enhanced as compared to the traditional key-word based retrieval system. The information on the web is available in various formats, such as RDF, XML and HTML.
