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, e.g. linked data, semantic data, semi-structured 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

WIS activities & news

Digital Birdwatching in the Rijksmuseum

Sunday October 4th, World Animal Day, 40 ornithologists, bird watchers and bird enthusiasts assembled in the library of the Rijksmuseum in Amsterdam for digital birdwatching. These bird experts were invited to use their knowledge ans skills to identify birds depicted on prints, paintings and other digital heritage objects. The event was an initiative of researchers from Delft University of TechnologyVU University Amsterdam and the Centrum Wiskunde & Informatica (CWI), assembled in the COMMIT/ research project SEALINCMedia, together with the Rijksmuseum, Naturalis and Wikimedia.

The digital bird watching event attracted quite some media attention, both in paper media (Trouw) and digital media (RTLParoolTelegraaf) and was even featured on the Dutch TV news (NOS, from 10:49). The full article can be read here.

Alessandro and Social Glass project featured on Dutch media

After the talk given during the Social Media Week in Rotterdam, Alessandro presented Social Glass and his work on Human-Enhanced Data Management on several Dutch media, including ad.nl and NRC.

CSCW 2016 Paper Accepted

The paper "Work and Play: An Experiment in Enterprise Gamification" by Alessandro Bozzon and Geert-Jan Houben, written in collaboration with IBM Benelux and its Centre of Advanced Studies, has been accepted for publication at CSCW 2015.

Jan Hidders appointed professor in Brussels

Jan Hidders has been appointed professor at the Free University in Brussels and will therefore leave our group to embrace the next step in his career and continue his research in web data management. WIS is currently reviewing candidates for a new faculty member in web/data science.

Social Glass project at SAIL 2015

Under the umbrella of AMS, the Social Glass team and the research group lead by Prof. Serge Hoogendoorn (Faculty of Civil Engineering and Geoscience)  developed and executed a pilot live experiment in Crowd Management during SAIL 2015, the international nautical event which took place from the 19th till the 23rd of August in Amsterdam. The pilot study used a combination of various methods of real-time data collection to give an optimum picture of pedestrian flows along the SAIL route and its different areas of interest. The main focus of the study was on how to gain reliable information on pedestrian flows during large-scale public events, such as SAIL, and use this effectively for crowd management. This experiment is a first step towards the development of a real-time monitoring system that can be utilized as a support tool by stakeholders responsible for the smooth running of such large-scale events. The experiment run parallel to the established crowd-management methods used by the municipality and, therefore, had no effect on the tasks of the crowd managers.

The project attracted the attention of several media, including ParoolTelegraph, ad.nl
