ArjenProf. Arjen P. de Vries is the head of the Information Access group at the Centrum Wiskunde & Informatica (CWI) in Amsterdam, and a part-time full professor in the area of multimedia data spaces at the Technical University of Delft. Starting with his PhD research into multimedia databases at University of Twente, De Vries has always been interested in search solutions where the advantages of automated search are combined with user interactions. He published more than 100 refereed papers, two of these recognized with a best (student) paper award (CIVR 2004 and ECIR 2007), and participated in several EU FP6 and FP7 research projects, including Vitalas (FP6), PuppyIR (FP7) and COMSODE (FP7).

De Vries (co-)chaired SIGIR Amsterdam in 2007 and has held a number of program chair positions, including CIKM (2012) and ECIR (2012, 2014). He is PC chair of SIGIR 2017 in Japan and the new ACM ICTIR conference in 2015, and has recently been appointed Editor-in-Chief of Springer’s Information Retrieval Journal (IRJ). De Vries is a member of the TREC PC, and a steering committee member of INEX. In November 2009, De Vries co-founded CWI spin-off company Spinque, to bring his “Search by Strategy” approach to the market: an iterative 2-stage search process that separates search strategy deļ¬nition (the how) from actual searching and browsing the collection (the what).
