Van der Zwaan, J.M. (author), Dignum, V. (author), Jonker, C.M. (author)In everyday life, people frequently talk to others to help them deal with negative emotions. To some extent, everybody is capable of comforting other people, but so far conversational agents are unable to deal with this type of situation. To provide intelligent agents with the capability to give emotional support, we propose a domain-independent...conference paper 2012

Van der Zwaan, J.M. (author), Dignum, V. (author), Jonker, C.M. (author)Recently, we proposed a dialogue model for social support. To validate this model, we analyzed 23 real world chat conversations. After some adjustments, the dialogue sequence patterns specified in the model cover 87.4% of the data. Based on this result, we conclude that the dialogue model accurately describes comforting conversations. Next, the...conference paper 2012

Van der Zwaan, J.M. (author), Dignum, V. (author), Jonker, C.M. (author)Recent developments in affective computing show that Embodied Conversational Agents (ECAs) are increasingly capable of complex social and emotional dialogues. Our research concerns the design and evaluation of an ECA that provides social support to children that are being bullied though the Internet. Recently, we proposed a domain-independent...conference paper 2012

Van der Zwaan, J.M. (author), Dignum, V. (author), Jonker, C.M. (author)An important task for empathic agents is to provide social support, that is, to help alleviate emotional distress. In this paper we specify verbal support types for a dialogue agent that provides social support, and propose an evaluation method for such an agent in a sensitive domain (cyberbullying) with a vulnerable target audience (children).conference paper 2012

Van der Zwaan, J.M. (author), Dignum, V. (author), Jonker, C.M. (author)An important task for empathic agents is to provide social support, that is, to help people increase their well-being and decrease the perceived burden of their problems. The contributions of this paper are 1) the specifcation of speech acts for a social support dialogue agent, and 2) an evaluation method for this agent. The dialogue agent...conference paper 2012

Lukosch, S.G. (author), Poelman, R. (author), Akman, O. (author), Jonker, P.P. (author)This paper introduces a novel gesture-based interface for crime scene investigation. The interface is part of a mediated reality system in which remote collaboration is supported. Requirements elicited from interviews and interactive sessions showed that our gesture-based user interface is effective in operating a 3D interface and allows the...conference paper 2012

Visser, W.M. (author), Hindriks, K.V. (author), Jonker, C.M. (author)In the context of practical reasoning, such as decision making and negotiation, it is necessary to model preferences over possible outcomes. Such preferences usually depend on multiple criteria. We argue that the criteria by which outcomes are evaluated should be the satisfaction of a person’s underlying interests: the more an outcome satisfies...conference paper 2011

Visser, W.M. (author), Hindriks, K.V. (author), Jonker, C.M. (author)Preferences are derived in part from knowledge. Knowledge, however, may be defeasible. We present an argumentation framework for deriving qualitative, multi-attribute preferences and incorporate defeasible reasoning about knowledge. Intuitively, preferences based on defeasible conclusions are not as strong as preferences based on certain...conference paper 2011

Pommeranz, A. (author), Detweiler, C.A. (author), Wiggers, P. (author), Jonker, C.M. (author)The impact of ubiquitous technology and social media on our lives is rapidly increasing. We explicitly need to consider personal values affected or violated by these systems. Value-sensitive design can guide a designer in building systems that account for human values. However, the framework lacks clear steps to guide elicitation of stakeholders...conference paper 2011

Baarslag, T. (author), Hindriks, K.V. (author), Jonker, C.M. (author)In every negotiation with a deadline, one of the negotiating parties has to accept an offer to avoid a break off. A break off is usually an undesirable outcome for both parties, therefore it is important that a negotiator employs a proficient mechanism to decide under which conditions to accept. When designing such conditions one is faced with...conference paper 2011

Van Vliet, B. (author), Caarls, W. (author), Schuitema, E. (author), Jonker, P.P. (author)Reinforcement learning is a way to learn control tasks by trial and error. Even for simple motor control tasks, however, this can take a long time. We can speed up learning by using prior knowledge, but this is not always available, especially for an autonomous agent. One way to add limited prior knowledge is to use subgoals, defining points...conference paper 2011

(author)Reinforcement Learning is a promising paradigm for adding learning capabilities to humanoid robots. One of the difficulties of the real world is the presence of disturbances. In Reinforcement Learning, disturbances are typically dealt with stochastically. However, large and infrequent disturbances do not fit well in this framework; essentially,...conference paper 2010

Van der Zwaan, J.M. (author), Dignum, M.V. (author), Jonker, C.M. (author)This paper proposes a design for an Embodied Conversational Agent (ECA) that empowers victims of cyberbullying by simulating peer support. The anti-cyberbullying buddy helps a child to cope with negative emotions due to a cyberbullying incident and it shows the child how to deal with future incidents of cyberbullying. The buddy interacts with...conference paper 2010
