Hi! I'm Xiaodong
About me
I am currently a Computer Science PhD student at University of Pennsylvania, as well as a research assistant in the Cognitive Computational Group, advised by Professor Dan Roth. Before coming to Penn, I was a master's student at University of Illinois, Urbana-Champaign.
My research generally focuses on Natural Language Processing, and my research interests include Knowledge Retrieval, Open-domain QA, Event/Entity Linking, Event/Entity Coreference Resolution, and Named Entity Recognition. My current research focuses on Open-domain QA.
