Dr. Chengkai Li is Associate Professor
and Director of the Innovative Database and Information Systems Research
Laboratory (IDIR) in the Department of Computer
Science and Engineering at the University of Texas at Arlington.
Dr. Li's research interests are in several areas related to big data
and data science,
including database, data mining, Web data management, and natural
language processing. His current research focuses on building large-scale human-assisting and human-assisted
data and information systems with high usability, low cost and applications for
social good. His current research projects are on computational journalism, crowdsourcing
and human computation, data exploration by ranking (top-k), skyline and
preference queries, database testing, entity query, and usability challenges
in querying graph data.
