Role of Semantic Relations in Hindi Word Sense Disambiguation

Semantic relations play an important role in resolving the ambiguity of a polysemous word. This paper investigates the role of hypernym, hyponym, holonym and meronym relations in Hindi Word Sense Disambiguation. In this work, we have considered five different cases: all relations, hypernym and hyponym, hypernym, hyponym and holonym. No semantic relations are used in the baseline. We obtained an overall improvement of 12.09% in precision over the baseline for the case when all relations are considered. The maximum improvement for single semantic relation was obtained using hyponym which resulted in an overall improvement of 9.86% in precision.
