Web Information Systems Group

The Software Technology department at Delft University of Technology (TU Delft) started with the appointment of prof.dr.ir. Geert-Jan Houben a new group on Web Information Systems (WIS) that is involved in the education in Computer Science and Information Architecture and that concentrates in its research on the engineering and science of the web, specifically on the engineering of web-based information systems with semantics-based user-adaptation.
Main topics in the group's research activities concern

Further details on the research activities that the WIS team is doing are listed at Research Lines

Trending research activities: ImREAL, WUDE, RDFGears, Twitcident, GeniUS and Twinder.
