On Friday 11th of September I pitched the medical relation extraction work of my CrowdTruth colleague Anca Dumitrache at the third Amsterdam Data Science: Coffee and Data event. The purpose of this was to get in touch with researchers that have medical datasets that are for instance incomplete or contain errors. With our research, we want to investigate how we can improve the quality of this data. Several other interesting presentations on data science in the medical domain were given at this event, which was hosted on the top floor of the VU University Amsterdam. Together with Merel van Empel, we also presented our latest work on gamification of crowdsourcing for advancing biology using BioCrowd. Feel fee to try out the game and provide us with feedback.
