This book contains the proceedings of the 20th edition of the Belgian-Netherlands Conference on Artificial Intelligence. The conference was organized by the Human Media Interaction group of the University of Twente. As usual, the conference was under the auspices of the Belgian-Dutch Association for Artificial Intelligence (BNVKI) and the Dutch Research School for Information and Knowledge Systems (SIKS). The conference aims at presenting an overview of state-of-the-art research in artificial intelligence in Belgium and the Netherlands, but does not exclude contributions from other countries. The received submissions show that AI researchers in Belgium and the Netherlands continue to work actively in many different areas of artificial intelligence and are open for new developments in technology and society. The annual BNAIC conference is the main meeting place for artificial intelligence researchers and practioners in Belgium and the Netherlands.
