Preface
It has been an interesting and enjoyable last four years. It is not often that you are allowed to work in such a warm and social environment, surrounded by smart people, and with so much freedom to do fun things.
This great experience can for a large part be contributed to my three supervisors, Frank van Harmelen, Rinke Hoekstra and Stefan Schlobach. I could not wish for a better combination of characters and skills in my supervisors. Thanks to Rinke, for his keen eye and practical advice on topics such as presentations, scientific writing, research in general, and leveraging the goals of a PhD with those of a scientific project. Thanks to Stefan, for the fun discussions, cups of coffee, and enriching my writing skills with some ‘youthful arrogance’. And thanks to Frank, for both pushing me to keep my eye on the prize and giving me a lot of freedom in my research at the same time. Wouter Beek, with whom I enjoyed sharing the office, deserves a special mention as well. I was lucky to work with Wouter, considering that our skills are largely complementary and our collaboration has proved quite productive. I am happy that we will continue collaborating after this thesis.
Regarding my thesis and its defence, I thank the committee (Sören Auer, Victor de Boer, Stefan Decker, Geert-Jan Houben and Peter Mika) for having read and accepted it.
I also thank all the people from the KRR&R and the Web & Media groups. Thanks Chris for the exhausting tennis matches, and sorry for distracting you so much. Thanks Albert for all the short walks outside. Filip, I hope you find the time to continue the nice projects that started in our room. And Archana, sorry for the workspace disruptions. Be gentle in your acknowledgements!
