Short Bio

I am a fifth-year Ph.D. student in Prof. Jiawei Han's Data Mining Group, Department of Computer Science, University of Illinois at Urbana-Champaign. Prior to UIUC, I received my bachelor degree from Shanghai Jiao Tong University, under the supervision of Prof. Xinbing Wang, and I was a member of IEEE Honored Class.

My research work lies in the intersection of data mining and natural language processing. Specifically, I focus on constructing multi-faceted taxonomies from unstructured text corpora, and utilizing constructed taxonomies to empower knowledge-centric applications. My proposed data-driven approach, without excessive human annotations, progressively constructs, enriches, and explores multi-faceted taxonomies by utilizing user-provided seed information as weak supervision and existing knowledge repositories as distant supervision.
