  • 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 ...
  • Design of knowledge-based agent as a social companion
    Wanner, Leo; André, Elisabeth; Blat, Josep; Dasiopoulou, Stamatia; Farrús, Mireia; Fraga, Thiago; Kamateri, Eleni; Lingenfelser, Florian; Llorach, Gerard; Martínez, Oriol; Meditskos, Georgios; Mille, Simon; Minker, Wolfgang; Pragst, Louisa; Schiller, Dominik; Stam, Andries; Stellingwerff, Ludo; Sukno, Federico Mateo; Vieru, Bianca; Vrochidis, Stefanos (Elsevier, 2017)
    We present work in progress on an intelligent embodied conversation agent that is supposed to act as a social companion with linguistic and emotional competence in the context of basic and health care. The core of the agent ...
  • 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 ...
  • KRISTINA: a knowledge-based virtual conversation agent
    Wanner, Leo; André, Elisabeth; Blat, Josep; Dasiopoulou, Stamatia; Farrús, Mireia; Kamateri, Eleni; Lingenfelser, Florian; Llorach, Gerard; Martínez, Oriol; Meditskos, Georgios; Mille, Simon; Minker, Wolfgang; Pragst, Louisa; Schiller, Dominik; Stam, Andries; Stellingwerff, Ludo; Sukno, Federico Mateo; Vieru, Bianca; Vrochidis, Stefanos (Springer, 2017)
    We present an intelligent embodied conversation agent with linguistic, social and emotional competence. Unlike the vast majority of the state-of-the-art conversation agents, the proposed agent is constructed around an ...
  • 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 argumentative dialogue system
    Rach, Niklas; Minker, Wolfgang; Wanner, Leo (CEUR Workshop Proceedings, 2017)
    In this work we propose a scheme for an Argumentative Dialogue System that allows a user to discuss a certain topic with a virtual agent using natural language. Starting from an agent vs agent case, we address the optimization ...
