In this first episode we enter the topic of explainability from the perspectives of computer science and linguistics. The guests are the speakers of the Collaborative Research Center, Prof. Katharina Rohlfing, psycholinguist at Paderborn University and Prof. Philipp Cimiano, computer scientist at Bielefeld University. The insights they are giving are about the motivation that drives them, the research goals they are pursuing and the societal impacts of XAI.
