I'm from Longkou (龙口), Shandong Province (山东), Mainland, China. I received my BS degree in Computer Science from Chengdu University of Science and Technology and MS degree from School of Software, Tsinghua University. I'm now a PhD candidate in CBS department, PolyU, studying now on the Chinese aspectual system under the supervision of Prof. Chu-Ren Huang.

I am interested in basic Natural Language Processing problems including Word Segmentation and Part-of-Speech Tagging with Machine Learning approaches. I also gained some experience on Sentiment Analysis and Information Extraction from the web when I was working in NEC Labs China after I graduated from Tsinghua University. Finally, I realized that the foundamental problems behind the NLP tasks greatly rely on more linguistic knowledge, especially semantic information of the lexicon. Syntactic parsing could not be done without incorporating semantic resources. The consideration is the main motivation for me to pursue a PhD degree in linguistics here now and to make efforts on bridging the gap between linguistics and computational linguistics.
