TamilTB

Tamil Dependency Treebank  (TamilTB) is an attempt to develop a syntactically annotated corpora for Tamil. TamilTB contains 600 sentences enriched with manual annotation of morphology and dependency syntax in the style of Prague Dependency Treebank.

EnTam - An English-Tamil parallel corpus

We have collected English-Tamil bilingual data from some of the publicly available websites for NLP research involving Tamil.The parallel corpora cover texts from bible, cinema and news domains.
