Hi! We are university researchers from Eindhoven (The Netherlands) and Hildesheim (Germany) and we're testing new recommender systems for movies and jokes. Please help us test these systems! You will use both systems and answer some questions about your experience. It will take about 30 minutes,. You will receive $5 in PayPal credit upon completion, and hopefully some nice movie and joke recommendations! Thanks a lot for helping us! --- The systems can be found here: http://131.155.121.180/ui_demos/Hildue/index.asp Bart Knijnenburg Researcher at the Human Technology Interaction group Eindhoven University of Technology The study is completely anonymous.
