Term papers

Write a problem statement for a research question in your discipline that you think can benefit from using NLP methods. Give some background about the problem, existing ways of addressing it, and how NLP can help. Write about what NLP approaches you learnt in this class can be useful for this problem. You are free to read any related literature, but I want you to come up with a problem statement of your own. Your writeups can be 2-4 pages long, and contain all the above mentioned information.

There is no meeting afterwards. I will send you feedback by email.
