Comunicació presentada a: 8th International Workshop On Spoken Dialogue Systems (IWSDS), celebrat del 6 al 9 de juny a Farmington, Estats Units. ; 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 the elderly which have been identified during various interviews and created a companion which talks and listens to the elderly users. Moreover, we conducted a user study with a small group of retired seniors living at home or in a nursing home. The results show that our companion and its dialogue were perceived very positively and that a social companion and conversation partner is indeed in demand by lonely seniors. ; This work is part of a project that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 645012.

Comunicació presentada a: INLG 2016 Workshop on Computational Creativity and Natural Language Generation, celebrat a Edinburgh, Escòcia, del 5 al 8 de setembre de 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 concise. We aim to approximate this ability by automatically varying the level of verbosity and directness of a given system action. In this work, we illustrate how verbosity and directness may be utilised in adaptive dialogue management and present different approaches to automatically generate varying levels of verbosity and directness for given system actions. Thereby, new and unforeseen system actions can be created dynamically. ; This paper is part of a project that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 645012.

Comunicació presentada a: 17th Annual Meeting of the Special Interest Group on Discourse and Dialogue; celebrada del 13 al 15 de setembre de 2016 a Los Angeles, USA ; 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 a user study creating a dialogue in a domain that has the potential capacity to reveal cultural differences. The dialogue contains different options for the system output according to cultural differences. We conducted a survey among Germans and Japanese to investigate whether the supposed differences may be applied in human-computer interaction. Our results show that there are indeed differences, but not all results are consistent with the cultural models. ; This work is part of a project that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 645012.
