Web Information Systems Group

The Software and Computer 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). The WIS research group concentrates in its research on engineering and science of the Web. The research specifically considers the role of Web data in the engineering of Web-based information systems. The group's research is aimed at improving the understanding of people's actions, interests, motivations, and behaviors on the Web, and subsequently leveraging that knowledge to build Web applications that are semantic, personalized and adaptive.
This includes topics in harvesting, integrating, transforming, analyzing, and retrieving Web data, with focus on the special properties of Web data. A large portion of Web data is human-made, e.g. in social networks or Twitter streams, and this brings scientific challenges in how to effectively attribute meaning to Web data. The size of the Web brings challenges in how to efficiently store, index, and analyze data at Web scale. WIS researchers and students strive to advance the state-of-the-art in relevant disciplines like user modeling, Web science, information retrieval, Web engineering, Web data management, and crowdsourcing.
Main themes in the group's research concern

  • Web data and semantics - managing, integrating and linking data in web-based information systems
  • Web analysis and user modeling - understanding usage and users in web-based information systems
  • Web engineering and adaptation - engineering and adapting web-based information systems
