The user can access limitless data from the web yet, it becomes a tedious task to retrieve relevant information. Data available on the Web covers diverse structures, formats and content. It also lacks a uniform organization of scheme that would allow easy access of data and information (Candan et al., 2001 ). Many frameworks have been proposed to support the search engine and information access. Resource Description Framework 1 (RDF), Web Ontology Language 2 (OWL) is one of the framework which provides a platform for standardization and organization of data from the Web. It has been WordNet (Fellbaum, 1998) , a lexical knowledge base system that has been adopted by the Semantic Web research community. The current essential need is to link WordNet with different resources in order to assist Natural Language Processing applications. IndoWordNet (Bhattacharyya, 2010) is an Indian community which builds WordNets for Indian languages. It is a multilingual WordNet which links WordNets of different Indian languages on a common identification number called as synset id given to each concept (Bhattacharyya, 2010) . It is constructed using the expansion model where Hindi WordNet synsets are taken as a source. The concepts provided along with the Hindi synsets are first conceived and appropriate concepts in target language are manually provided by the language experts.
