Natural Language Processing

I am currently working on improving the state-of-the-art and exploring new tasks for machine reading comprehension.

I was the lead developer of the Cornell Chinese Belief and Sentiment Detection Systems, which ranked 1st in BeSt Evaluation at TAC 2016 and TAC 2017 and was employed in the TAC 2017 Cold Start KB task as part of the Tinkerbell team.

AI in Board Games

I designed Yixin, an AI program playing Gomoku and Renju. It was the world champion AI, the winner of the 13th, 14th, 15th, 16th, 17th, 18th, and 19th Gomocup.

Yixin was the first Gomoku and Renju AI that can compete at the human champion level. It beat Taiwan's Meijin title holder Lin Shu-Hsuan and the world Gomoku champion Rudolf Dupszki in 2017, and drew with world Renju champion Qi Guan in 2018.

I have been managing Gomocup (with Tianyi Hao) since the 17th Gomocup, 2016.
