Arjen P. de Vries
Computer scientist specialized in information access to dataspaces through the integration of information retrieval and databases.


PhD thesis and other publications.


Group leader of the Centrum Wiskunde & Informatica (CWI) research group Interactive Information Access (INS2), the main topics of my research include structured document retrieval and entity ranking, multimedia information retrieval, the application of information retrieval theory to recommendation systems and social media, nearest neighbour search in high dimensional spaces, the integration of information retrieval and database technology, and the evaluation methodology needed in these novel information retrieval application areas. I am very interested into the newly proposed dataspaces abstraction.

September 1st, 2008, I have been appointed Full Professor Multimedia Dataspaces (nl) at Delft University of Technology. May 8th, 2009, I gave my inaugural lecture "Zoektocht op schema" (more to follow...). Finally, I am co-founder of the recent CWI spin-off Spinque.

Current projects

I am actively involved in the PuppyIR FW7 Strategic Research Project. A fun (but never funded) project with Mark van Doorn (then at Philips) developed the idea of Ambient Narratives, and resulted in several publications as well as Mark's successfully defended PhD thesis.


At Delft University (my Delft homepage), I teach course IN4144 (Data Science), part of the Media and Knowledge Engineering Master's program.

Professional Activities

Refer to my CV for a recently updated overview of professional activities. Highlights include the organization of SIGIR 2007 in Amsterdam, together with Wessel Kraaij, Djoerd Hiemstra, and Maarten de Rijke, and the coordination of the TREC Enterprise Track with Peter Bailey, Nick Craswell, Ian Soboroff and Paul Thomas. At INEX (an evaluation of structured document retrieval, or XML-IR), I have started the entity ranking track.


Former projects include the NWO Open Competition Cirquid, the MultimediaN precursor MIA, and the Senter DMW and Waterland projects. Information about my first steps in research can be found (though rather outdated) at the Mirror Research Page.

Finally, I am member of ACM (SIGMOD and SIGIR), and a board member of the (Dutch) WGI, Vereniging Werkgemeenschap Informatiewetenschap (i.e., Society for Information Science).
