Ph.D. Candidate in
Department of Computer Science and Engineering
Pennsylviania State University
Advisor: Professor Prasenjit Mitra
I received my bachelar's degree from School of Computer Science and Technology in Harbin Institute of Technology in July 2006. Then I came to Penn State to pursue Ph.D. Degree in Department of Computer and Engineering. The Chinese character of my first name (Xiao) means “deep and clear water”.
Project and Research:
My research interest lies in Text Data Mining, Information Retrieval and Databases. I'm now participating the GeoCAM project (a project of GeoVISTA center) and designed and implemented one of the core components (route parts extraction and classification) of GeoCAM system. I focus on extraction and interpretation of accounts of movements in text documents. To be more specific, I am working on sentence level and term level route information extraction and classification, sequence labeling and semi-supervised learning to improve extraction accuracy.
In my first year, I did research in Databases. I focused on query processing and optimization in wireless broadcast environment.
