R Vijayakrishna, L. Sobha · 2008
In this paper, we present a domain focused Tamil Named Entity Recognizer for tourism domain. This method takes care of morphological inflections of named entities (NE). It handles nested tagging of named entities with a hierarchical tagset containing 106 tags. The tagset is designed with focus to tourism domain. We have experimented building Conditional Random Field (CRF) models by training the noun phrases of the training data and it gives encouraging results. 1
