Creation of lexical relations for indoWordNet

Abstract

WordNet is an electronic lexical database available on-line as a powerful resource to the researchers in the area of computational linguistics, text processing and other related areas. WordNet for Hindi language has al-ready been developed by IIT, Bombay. The Indian languages WordNets are being created using expansion approach from Hindi Word-Net under IndoWordNet project. In expan-sion approach, semantic relations are bor-rowed from the reference language, while the lexical relations need to be created for each language, as these relations are language de-pendent. This paper describes the process of creation of lexical relations like antonym, compounding, conjunction and gradation for IndoWordNet. A lexical creation tool has been presented in this paper with provision to create lexical relations in target language on the basis of relations created in Hindi Word-Net and with another provision to create lexi-cal relations in target language without refer-ring to Hindi WordNet. It has been observed that lexical relations for target language can be created easily on the basis of relations cre-ated in Hindi WordNet for Hindi in-family languages, while for the languages that do not fall in the same family provision of creation of lexical relation without referring to Hindi WordNet can be used.
