Chomsky Hierachy

Went to the TAG study group for 1.5 hours. It is very interesting. Reviewed again the Chomsky hierachy. Learned more about String/Tree Grammar. Felt very happy when I am learning.

Pull up the document for the preparation with Anoop's meeting tomorrow.

Found some new paper about question and summarization.
Need to investigate more.

Need to learn to write up things. Need to put things down from reading and thinking, so as to make real noticable progress.
