Today I was appointed as Visiting Professor at the National Institute of Informatics (NII), effective 1. April 2018 for the forthcoming four years. I am very grateful for the generous support of the NII, and I am looking forward to visiting the NII approximately once or twice a year for a few weeks to collaborate on research relating to recommender systems, machine learning, natural language processing and our other research areas. I have been working closely together with the NII in Tokyo for quite a while, in particular with the Digital Content and Media Division and Prof Dr Akiko Aizawa. As such, I am glad to continue and intensify the collaboration for at least four years.
