Semi-Automatic Extension of Sanskrit Wordnet using Bilingual Dictionary

In this paper, we report our methods and results of using, for the first time, semi-automatic approach to enhance an Indian language Wordnet. We apply our methods to enhancing an already existing Sanskrit Wordnet created from Hindi Wordnet (which is created from Princeton Wordnet) using expansion approach. We base our experiment on an existing bilingual Sanskrit English Dictionary and show how lemma in this dictionary can be mapped to Princeton Wordnet through which corresponding Sanskrit synsets can be populated by Sanskrit lexemes. This our method will also show how absence of resources of a pair of languages need not be an obstacle, if another resource of one of them is available. Sanskrit being historically related to languages of Indo-European family, we believe that this semi-automatic approach will help enhance Wordnets of other Indian languages of the same family.
