My name is Zhengzhong Liu (People often refer me with my nickname Hector). I am a PhD researcher on Natural Language Processing and Computational Linguistics at Carnegie Mellon University, working with Professor Teruko Mitamura and Professor Eduard Hovy. Prior to my PhD, I obtained my master at CMU with Teruko and Ed. And prior to that, I obtained my bachelor degree in the Department of Computing from the Hong Kong Polytechnic University, working with Professor Qin Lu.
I am broadly interested in solving problems by combining machine learning techniques with linguistic insights and human knowledge. In the early days I worked on semantic web problems such as entity disambiguation(WWW’12, entity linking) or slot filling. Particularly, I love incorporating knowledge into NLP problems, such as in information retrieval (SIGIR’18,CIKM’17), or core NLP tasks (ACL’16).
