About Me

I am affiliated with Natural Language Processing Group at Institute of Computing Technology, Chinese Academy of Sciences. My area of interest is statistical machine translation. I received my PhD degree in Computer Science from Institute of Computing Technology, Chinese Academy of Sciences in 2007. I graduated from Wuhan University with a bachelor degree in Computer Science in 2002. The pronunciation of my first name is the same with the English word young. The last name pronounces similarly to the English word new, except for replacing n with l. Together with other researchers sharing the same name with me, I am ranked at #182 (sorted by incoming citations) in ACL Antology Network.

Collected Tips

• How to Do Research at the MIT AI Lab by David Chapman (Editor)
  Highlights (statements that I like):
  • The few people in the field who seem to consistently succeed, turning out papers year after year, in fact fail as often as anyone else.
  • Crucial to success is making your research part of your everyday life.
• Richard Hamming "You and Your Research" by J. F. Kaiser
  Highlights:
  • Once you get your courage up and believe that you can do important problems, then you can.
  • In summary, I claim that some of the reasons why so many people who have greatness within their grasp don't succeed are: they don't work on important problems, they don't become emotionally involved, they don't try and change what is difficult to some other situation which is easily done but is still important, and they keep giving themselves alibis why they don't. They keep saying that it is a matter of luck.
• The Researcher's Bible by Alan Bundy, Ben du Boulay, Jim Howe, and Gordon Plotkin
  Highlights:
  • The way out of this vicious circle is to realise that research ability does not depend on some magic essence. It is a skill which can be learnt, like any other.
• How to Write a Great Research Paper by Simon P. Jones
  Highlights:
  • Giving credit to others does not diminish the credit you get from your paper.
  • Failing to give credit to others can kill your paper!
• How to Find Research Problems by Jason Eisner
  Highlights:
  • Ignorance leaves your mind free to see new ways of doing things.
