Indian parser

Our team participated to the ICON 2010 contest on dependency parsing for Indian languages.

The DeSR parser achieved best UAS (Unlabeled Attachment Score) on all languages with an average of 90.94% and a remarkable 94.57% on Hindi-coarse (where I tuned the parser most).

On LAS (Labeled Attachment Score) DeSR is first with 88.98% on Hindi-Coarse and second on Hindi-Fine with 87.49%.

Bangla and Telugu have quite small training sets (7000 tokens) but nonetheless DeSR is close to first at about 1% distance.
