Victor de Graaff is exploring the possibilities to create a geo-social recommender system. This is a recommender system for geographical products, such as real estate or holiday homes, using social media-based user profiles. This work is carried out in close collaboration with the holiday home portal EuroCottage.

Together with Jan Flokstra and Bas Retsios, Victor has created an app to collect trajectories from students during a treasure hunt at the welcome week for new students at the University of Twente.

This app is available in the App Store and on Google Play.
