My name is Benjamin Timmermans, and I am a researcher in the Web & Media Group at the Vrije Universiteit Amsterdam. I work on the CrowdTruth project in a collaboration with IBM Research New York and IBM Netherlands, lead by Lora Aroyo, Chris Welty and Robert-Jan Sips. My research involves the crowdsourcing of ground truth data for the training and evaluation of cognitive computing systems such as IBM Watson. This is done using our CrowdTruth framework, which allows the harnessing of disagreement and interpretations on texts, images, sounds and videos.

I am the study advisor for international students in the computer science bachelor at the Vrije Universiteit. Furthermore, I teach in the Watson Innovation master course as part of the collaborative innovation between IBM and the Vrije Universiteit, and I supervise the bachelor thesis and final project in the Information Multimedia and Management program of the university.

In this blog I post about my research at the VU University Amsterdam, data science and computer science in general. Please see my curriculum vitae for more details about my history.
