In my undergrad years I was quite interested in NLP and compilers. Although I don't do anything in those areas anymore, Vikram, Deepak and I had kickstarted a project in NLP on which some students still work in IITK and use the programs that we wrote back then. Here are some of the papers that we got for our work - they can serve as references for understanding what we did. Our guides in this endeavour were Dr. Amitabha Mukerjee and Dr. A. M. Raina.
(I am still looking for copies, will put them online soon)

In case you are curious, here is one on my B.Tech. project with Chaitanya. Our supervisor was Dr. S. K. Aggrwal.
