Pieters, W. (author), Padget, J. (author), Dechesne, F. (author), Dignum, V. (author), Aldewereld, H.M. (author)Security policies in organisations typically take the form of obligations for the employees. However, it is often unclear what the purpose of such obligations is, and how these can be integrated in the operational processes of the organisation. This can result in policies that may be either too strong or too weak, leading to unnecessary...conference paper 2013

Schmidt Jensen, A. (author), Aldewereld, H.M. (author), Dignum, M.V. (author)It is hard, if not impossible, to assume anything about agents’ behavior in a society with heterogeneous agents from different sources. Organizations are used to restrict and guide the agents’ actions such that the global objectives of the society are achieved. We discuss how agents can be supported to include organizational objectives and...conference paper 2013

King, T.C. (author), Dignum, M.V. (author), Van Riemsdijk, M.B. (author)In multi-agent organizations, contractual obligations and prohibitions are important for governing autonomous agents. However, agents may only wish to participate in an organization if the contracts they engage in respect and satisfy their policies specifying how the agent may be used, we call these use policies and they specify what norms may...conference paper 2013

Van der Zwaan, J.M. (author), Dignum, M.V. (author), Jonker, C.M. (author)This paper presents a qualitative study of the supportive behavior of an Embodied Conversational Agent (ECA) that provides social support to cyberbullying victims. The results indicate that social support is conveyed. In addition, we demonstrate a method that can be utilized to evaluate embodied agents for vulnerable target audiences (e.g.,...conference paper 2013

Correlje, A.F. (author), Cuppen, E.H.W.J. (author), Dignum, M. (author), Pesch, U. (author), Taebi, B. (author)Shale gas is a relatively new technology that is embraced by some as the ‘game changer’ in energy land, and opposed by others because of its risks and other potentially negative impacts. Recent experiences in the US and Europe have shown that the technology witnesses divergent societal acceptance issues. The value-laden basis of such resistance...conference paper 2013

Li, T. (author), Jiang, J. (author), Aldewereld, H.M. (author), de Vos, M. (author), Dignum, V. (author), Padget, J.A. (author)Within a virtual organization, more than one institution might be involved in the regulation of actors’ behavior. Each institution specifies a set of norms covering a specific aspect of the problem domain with a governance scope defining its remit. Together, they govern the participants and reflect the objectives of the organization. With actors...conference paper 2013

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

To adapt to such dynamics, not only should organizational design provide sufficient representation of organizational requirements, but also provide control mechanisms to switch between different...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

Jiang, J. (author), Aldewereld, H.M. (author), Dignum, V. (author), Tan, Y. (author)Agents interact with each other within a set of norms, which is expressed at different levels of abstraction that capture different con- texts and operationalizations. Current normative frameworks deal with norm operationalization, yet few consider the contextual aspects of norms. Moreover, most frameworks are based on the independent...conference paper 2012

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
