Short Bio

I am a fourth-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 focuses on constructing multi-faceted taxonomy from massive unstructured text corpora and enhancing text understanding with constructed taxonomies. My works lay in the intersection of data mining, natural language processing and information retrieval.

What's new!

July 2019 - I am honored to receive KDD 2019 Travel Award and will attend KDD to present our tutorial (together with Jingbo Shang and Liyuan Liu) on Constructing and Mining Heterogeneous Information Networks from Massive Text.

Mar. 2019 - I am honored to receive 2019-2020 Yunni & Maxine Pao Memorial Fellowship.

Dec. 2018 - I am honored to receive 2018 Data Mining Research Excellence Award (Gold).

Nov. 2018 - My work on Mining Entity Synonym Set with Distant Supervision and Set Representation Learning has been accepted into AAAI 2019. Its PyTorch implementation is available in Github along with the synonym datasets. Full documentations of code are available at here.

Nov. 2018 - Together with Yu Meng, our paper on Weakly-supervised Hierarchical Text Classification has been accepted into AAAI 2019. Code to be released soon.

Aug. 2018 - Collaborated with Maryam Karimzadehgan and Donald Metzler, our work on Multi-Task Learning for Personal Search Ranking with Auxiliary Query Clustering has been accepted into CIKM 2018.

Aug. 2018 - Together with Yu Meng and Jingbo Shang, two papers about Weakly-supervised Text Classification and Stance-aware Search Ranking have been accepted into CIKM 2018.
