I am a Professor in Institute of Computer Science and Technology (ICST), Peking University (PKU), China. I received B.S., M.S. and Ph.D. in Computer Science from Department of Computer Science and Technology of PKU in 1991, 1994 and 2000 respectively. 


Research Biography

My major research interests include Natural Language Processing, Semantic Data Management and Knowledge-based Intelligent System. Recently, I am interested in several research topics including Information Extraction, Knowledge Graph, Question Answering & Reading Comprehension, Dialogue System and Knowledge-based Intelligence applications. 

I am a distinguished member of China Computer Federation (CCF), the secretary-general of CCF TCCI (Technical Committee on Chinese Information Technology), a member of CCF Task Force on Big Data, a member of CCF Network and Data Communications, a senior member of CIPS Social Media Processing Committee.

I undertook 15 national research projects (include National Natural Science Foundation of China, National Hi-Tech Project) and is/was the PI in 7 of them. I also undertook 8 provincial and ministerial level scientific research projects, and was the PI in 4 of them.

I published over 100 referred papers (more than 40 of them are top ranked by CCF, such as ACL, AAAI, IJCAI, KDD, WWW, SIGMOD, VLDB; AI, TODS, VLDB Journal, TKDE etc.), obtained 20 patents, and won 7 official awards in national and provincial/ministerial level, including National Awards of Scientific and Technological Process, Second Prize (Ranking the first one).

I also won China Youth Science and Technology Award (2007) and Special Award of Technological Innovation titled "Honor of Science and Technology" by Beijing Municipal Government (2007).
