  • A social companion and conversation partner for elderly
    Miehle, Juliana; Bagci, Ilker; Minker, Wolfgang; Ultes, Stefan (Springer, 2017)
    In this work, we present the development and evaluation of a social companion and conversation partner for the special user group of elderly.With the aim of designing a user-adaptive system, we responded to the desires of ...
  • Adaptive dialogue management in the KRISTINA project for multicultural health care applications
    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 ...
  • Automatic modification of communication style in dialogue management
    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 ...
  • Cultural communication idiosyncrasies in human-computer interaction
    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 ...
  • Exploring the applicability of elaborateness and indirectness in dialogue management
    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 ...
  • Interaction quality estimation using long short-term memories
    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 ...
  • Recurrent neural network interaction quality estimation
    Pragst, Louisa; Ultes, Stefan; Minker, Wolfgang (Springer, 2016)
    Getting a good estimation of the Interaction Quality (IQ) of a spoken dialogue helps to increase the user satisfaction as the dialogue strategy may be adapted accordingly. Therefore, some research has already been conducted ...
  • Towards a multimedia knowledge-based agent with social competence and human interaction capabilities
    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 ...
  • Towards an ontology-driven adaptive dialogue framework
    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 ...
