The IDIR Lab in the CSE Department of UT Arlington conducts research in big data management and mining, with current focus on building large-scale human-assisting and human-assisted data and information systems with high usability, low cost and applications for social good. In particular, we work on computational journalism, crowdsourcing and human computation, database exploration by ranking (top-k), skyline and preference queries, database testing, entity query, usability challenges in querying graph data, and Web data management.
