I am currently a fifth year Ph.D. student in Prof. Xifeng Yan’s Group, at Department of Computer Science, University of California, Santa Barbara. Prior to UCSB, I received my bachelor degree from Nanjing University, under the supervision of Prof. Yu-Feng Li at LAMDA Group Led by Prof. Zhi-Hua Zhou, and I was a member of Kuang Yaming Honor School. My research lies between data mining and natural language processing. Particularly, I focus on mining structed knowledge from unstructed text and constructing knowledge graph, where such knowledge can facilitate intelligent analysis and applications.
