Abstract:
WordNet is a crucial resource that aids in Natural Language Processing (NLP) tasks such as Machine Translation, Information Retrieval, Word Sense Disambiguation, Multilingual Dictionary creation, etc. The IndoWordNet is a multilingual WordNet which links WordNets of different Indian languages on a common identification number given to each concept. WordNet is designed to capture the vocabulary of a language and can be considered as a dictionary cum thesaurus and much more. WordNets for some Indian Languages are being developed using expansion approach. In this paper we have discussed the details and our experiences during the evolution of this database design while working on the Indradhanush WordNet Project. The Indradhanush WordNet Project is working on the development of WordNets for seven Indian languages. Our database design gives an efficient plan for storage of WordNet data for all languages. In addition it extends the design to hold specific concepts for a language.
