Juliana Miehle studied Electrical Engineering with concentration in “Communication and System Technology” at Ulm University, Germany. She received her B.Sc. degree in 2013 and her M.Sc. degree in 2015. After doing an internship at Nara University of Science and Technology, Japan, she joined the Dialogue Systems Group at Ulm University, Germany, under the supervision of Prof. Dr. Dr.-Ing. Wolfgang Minker in 2016 as a research assistant and Ph.D. student. Her research interests include user-adaptive dialogue management, communication styles in human-computer interaction, and machine learning applications.Wolfgang Minker received the diploma (M.Sc.) and Ph.D. degrees in engineering science from the University of Karlsruhe, Germany, in 1997, and the Ph.D. degree in computer science from Université Paris-Sud, France, in 1998. From 1993 until 2000, he was a Teaching Assistant with LIMSI-CNRS, Université Paris- Sud, France, and subsequently worked as a Senior Researcher withthe Dialogue Systems Group of Daimler Chrysler Research and Technology, Ulm, Germany, from 2000 to 2003. Since 2003, he has been a Full Professor with Ulm University, Germany, and also became a Co-Director of the International Research Laboratory “Multimodal Biometric and Speech Systems”, ITMO University, St. Petersburg, Russia, in 2017. The research at his group is focused on dialogue systems with special interests in spoken dialogue interaction in ambient intelligent environments, assistive, adaptive, and proactive spoken language dialogue interaction, dialogue modeling, and argumentative dialogue systems.Koichiro Yoshino is a Team Leader at Guardian Robot Project (GRP) in Institute of Physical and Chemical Research (RIKEN), and a Visiting Associate Professor at Nara Institute of Science and Technology (NAIST). He received his bachelor degree of arts from Keio University in 2009, master degree of informatics from Kyoto University in 2011, and Ph.D. in informatics fromKyoto University in 2014. He worked at Kyoto University as a postdoc, and NAIST as an assistant professor. He is working on areas of spoken and natural language processings, especially on robot dialogue systems. Dr. Koichiro Yoshino received several honors including the best paper award of IWSDS 2020, and the best paper award of the 1st NLP4ConvAI workshop. He is a member of IEEE, SIGDIAL, ACL, ANLP, IPSJ, RSJ, and JSAI.
