Zilong Chen

I am a Ph.D student at Department of Computer Science and Technology, Tsinghua University, where I am advised by Prof. Huaping Liu and work closely with Dr. Feng Wang and Prof. Yikai Wang. Before joining Tsinghua University, I completed my undergraduate studies at Xi'an Jiaotong University under the supervision of Prof. Minnan Luo, focusing on knowledge graphs and their applications in natural language processing.
