    I published an update to our dataset of crowdsourced annotations on controversy aspects, as part of the ControCurator project. Experimental Setup We evaluated the controversy aspects through a crowdsourcing experiment using the CrowdFlower platform. The collected annotations from this experiment were evaluated using the CrowdTruth methodology for measuring the quality of the annotations, the annotators, […]

    I like geographic data, and in recent years developed a simple tool to easily visualize all of my Google location history data in a single zoomable and interactive map. It converts your complete Google location history data for use in a Google Fusion Table. You can customize the visualization to your own preference in the […]

    Our paper Computational Controversy has been accepted at the SocInfo 2017 conference! Abstract Climate change, vaccination, abortion, Trump: Many topics are surrounded by fierce controversies. The nature of such heated debates and their elements have been studied extensively in the social science literature. More recently, various computational approaches to controversy analysis have appeared, using new […]

    Why would decision makers attend these masterclasses? To make informed business decisions on and around cognitive technologies, decision makers must understand the foundations, as well as the context, of these technologies. What do we offer? The IBM Benelux Center for Advanced Studies (CAS) teamed up with our long term collaborators in academia to deliver two […]

  • 12/11/17--04:13: Machine Learning Overview
  • There have been a lot of developments in the last years in machine learning. One of the main developments of course has been deep learning, but now also generative adversarial networks are becoming more and more interesting. In some of my presentations I have been using the following graph to model and explain the most […]

    How do you avoid spending too much? Studies on buying behaviour have emphasized that one way to do that is to raise the “pain of paying”. This uncomfortable feeling that comes with paying differs across payment methods and influences our decision to buy. Using a credit card is associated with a lower “pain of paying” […]
