The Centre for BOLD Cities is a research collaboration between Leiden University, Delft University of Technology and Erasmus University Rotterdam. It focuses on the possibilities and challenges of using big, open and linked data for urban governance. Looking into both the perspective of urban citizens and citymakers, the Centre for BOLD Cities connects researchers from various disciplines, such as data science, sociology and public administration. In addition, the Centre collaborates with societal and governmental partners on a regular basis. As such, the Centre for BOLD Cities aims to help transform the ‘smart city’ into the ‘shared city’, in which concerns and ideas of all stakeholders are equally considered.
