Hi, let me give you a short #introduction to my research interests. I am Ulrich or Uli ( for those who know me longer). I got interested in #ArtificialIntelligence during my study of #ComputerScience back to the 1980ies. At that time, researchers wanted to build #AI systems that use a world model to make decisions. This poses challenges for #KnowledgeRepresentation, #ConstraintSolving, #ExplanationGeneration, #PreferenceModeling, and #DefeasibleReasoning. They keep me inquiring and studying!
