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

Schmidt Jensen, A. (author), Dignum, V. (author), Villadsen, J. (author)Open systems are characterized by a diversity of heterogeneous and autonomous agents that act according to private goals, and with a behavior that is hard to predict. They can be regulated through organizations similar to human organizations, which regulate the agents' behavior space and describe the expected behavior of the agents. Agents need...conference paper 2014

Dignum, V. (author), Aldewereld, H.M. (author), Vasconcelos, W. (author)Norms have been used to represent desirable behaviours that software agents should exhibit in sophisticated multi-agent solutions. An important open research issue refers to group norms, i.e. norms that govern groups of agents. Depending on the interpretation, group norms may be intended to affect the group as a whole, each member of a group, or...conference paper 2015

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

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

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

Dignum, V. (author), Jonker, C.M. (author), Prada, R. (author), Dignum, F. (author)Socially intelligent systems exhibit, understand, and reason about social behavior, in order to support people in their daily lives. We claim that a fundamental new approach based on social concepts is needed to build these socially intelligent systems. In this paper, we explore how the concepts of social practices and social identities can be...conference paper 2014

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

How are SEAPs aiming to contribute to the process of local energy transition and how can their performance be improved? The text of thirty...conference paper 2015

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)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

Hesan, R. (author), Ghorbani, A. (author), Dignum, M.V. (author)In system dynamics modeling, differential equations have been used as the basic mathematical operator. Using difference equation to build system dynamics models instead of differential equation, can be insightful for studying small organizations or systems with micro behavior. In this paper we explain how we can use difference equations to build...conference paper 2014
