About
I am a research lecturer at
LTRC, IIIT-Hyderabad where I recently completed my PhD in Computational Linguistics.
I had been working towards
building a generic dependency parsing paradigm for morphologically rich free word order languages (with special focus on Indian languages, such as Hindi, Bangla, Telugu, etc.).
Towards this end, I have proposed a generalized 2-stage constraint
based hybrid parsing approach. I have also applied some of the
salient properties of this paradigm to data-driven dependency
parsing.
I am involved in the development of Hindi/Urdu dependency
treebank that is part of a larger
Hindi/Urdu treebanking project.
My broad research interests are NL Parsing, NL Modeling, Dependency Grammar, and Cognitive Science.
