Summary
The UD Tamil treebank is based on the Tamil Dependency Treebank created at the Charles University in Prague by Loganathan Ramasamy.
Introduction
The treebank was part of HamleDT, a collection of treebanks converted to the Prague dependency style (since 2011). Later versions of HamleDT added a conversion to the Stanford dependencies (2014) and to Universal Dependencies (HamleDT 3.0, 2015). The first release of Universal Dependencies that includes this treebank is UD v1.2 in November 2015. It is essentially the HamleDT conversion but the data is not identical to HamleDT 3.0 because the conversion procedure has been further improved.
