SemIndex: Efficient indexing mechanism for ontologies

To make machine understand the semantics of web page, there is need for representation language other than HTML, XML. Semantic Web, allows the information to be represented in well-defined manner using different languages like RDF, OWL which enhances the inference power of the machines, making the contents machine-interpretable. Indexing of the fetched web contents for these representation languages for effective information retrieval is the key issue of research. In this paper comparative analysis of existing indexing techniques for RDF documents is done. And framework is proposed and implemented for indexing crawled ontologies represented in Semantic Web Language like RDF language.
