Mapping Hindi Text To Indian sign language with Extension Using Wordnet

Sign language serves as a primary mode of communication for deaf people. It is a major linguistic challenge which researchers all over the globe have taken up and built systems to facilitate the process of understanding the natural language by means of sign language. This paper discusses a system that is built mainly to translate Hindi text to the Indian sign language. The model is implemented using the dependency parser and POS tagger which correctly categorize the input words into their syntactic forms. Later the knowledge of wordnet is applied to increase the efficiency of the system. This paper primarily emphasizes on the role of wordnet in the expansion of the scope of dictionary. This further serves as an integral part in constructing the Indian sign language system.
