  • Pragst, Louisa; Ultes, Stefan; Kraus, Matthias; Minker, Wolfgang (University of Gothenburg, 2015)
    The goal of the EU-funded KRISTINA project is to help migrants in European countries get information about their resident country’s health care system by the means of a socially competent dialogue system. This system has ...
  • Pragst, Louisa; Miehle, Juliana; Ultes, Stefan; Minker, Wolfgang (ACL (Association for Computational Linguistics), 2016)
    In task-oriented dialogues, there is often only one right answer the system can give. However, a lack of variation can seem repetitive and unnatural. Humans change the way they express something, e.g. by being more or less ...
  • Yoshino, Koichiro; Miehle, Juliana; Pragst, Louisa; Ultes, Stefan; Nakamura, Satoshi; Minker, Wolfgang (ACL (Association for Computational Linguistics), 2016)
    In this work, we investigate whether the cultural idiosyncrasies found in human human interaction may be transferred to human-computer interaction. With the aim of designing a culture-sensitive dialogue system, we designed ...
  • Pragst, Louisa; Minker, Wolfgang; Ultes, Stefan (Springer, 2017)
    In this paper, we investigate the applicability of soft changes to the system behaviour, namely changing the amount of elaborateness and indirectness displayed. To this end, we examine the impact of elaborateness and ...
  • Rach, Niklas; Minker, Wolfgang; Ultes, Stefan (ACL (Association for Computational Linguistics), 2017)
    For estimating the Interaction Quality (IQ) in Spoken Dialogue Systems (SDS), the dialogue history is of significant importance. Previous works included this information manually in the form of precomputed temporal features ...
  • Wanner, Leo; Blat, Josep; Dasiopoulou, Stamatia; Domínguez Bajo, Mónica; Llorach, Gerard; Mille, Simon; Sukno, Federico Mateo; Kamateri, Eleni; Kompatsiaris, Ioannis; Vrochidis, Stefanos; André, Elisabeth; Lingenfelser, Florian; Mehlmann, Gregor; Stam, Andries; Stellingwerff, Ludo; Lamel, Lori; Vieru, Bianca; Minker, Wolfgang; Pragst, Louisa; Ultes, Stefan (ACM Association for Computer Machinery, 2016)
    We present work in progress on an intelligent embodied conversation agent in the basic care and healthcare domain. In contrast to most of the existing agents, the presented agent is aimed to have linguistic cultural, social ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Pragst, Louisa; Ultes, Stefan; Vrochidis, Stefanos; Wanner, Leo (ACM Association for Computer Machinery, 2016)
    In this paper, we describe the principles and technologies that underpin the development of an adaptive dialogue manager framework, tailored to carrying out human-agent conversations in a natural, robust and exible ...
