The Keith van Rijsbergen Award is meant to encourage and recognise researchers who have made significant contributions in using theory to develop new information retrieval models, paradigms, concepts or metrics, thereby addressing foundational aspects in information retrieval and opening up new ways of thinking about information retrieval. 

The Award Panel was particularly impressed by Maarten’s sustained efforts over the years in ensuring strong theoretical foundations in his diverse and numerous contributions to information retrieval, as well as his sustained efforts in pushing the boundaries of the field.

Maarten held a keynote on 'Explorations in Transparency' at the 46th European Conference on Information Retrieval (ECIR). He is researcher at the Information Retrieval Lab (IRLab) of the Informatics Insititute UvA.
