Data and Knowledge
Research Group

The Data and Knowledge Research Group at UNSW is a world leader in database, data management, and (big) data analytics. Our research accelerates data-intensive applications, and supports insightful knowledge extraction from large-scale, complex and dynamic real-life datasets. Our investigation covers graph/network data, spatial-temporal data, relational data, multi-media data, text data, and more. Our research generates translational outcomes in e-business, finance, health, mining, cyber-security, online education and training, transportation, and biotechnology.
