The seminar brought together researchers from computer sciences (in particular from the fields of multi-agent systems and self-organisation) and from social sciences to discuss the impact of the use of social concepts in technical systems as well as the interaction between technical and social systems. In an engaging and interactive setting, the problem was illuminated from a technical as well as a philosophical and legal point of view. The talks, discussions, and working groups identified a growing body of work in the field, a number of interesting and promising research avenues, as well as a set of open issues for future investigation.

On the one hand, large-scale self-organising systems gain traction in real-world settings, e.g., in the autonomous control of the power grid or in personal transportation scenarios. On the other hand, our lives are more and more pervaded by socio-technical systems that rely on the interaction of existing, complex social systems and technical systems that in many ways mirror and form the social relationships of their users. The seminar brought together researchers from a variety of domains to discuss the technical, legal, and social issues these trends incur. One focus was how social concepts can be formalised and implemented to make technical Except where otherwise noted, content of this report is licensed under a Creative Commons BY 3.0 Unported license Social Concepts in Self-organising Systems, Dagstuhl Reports, Vol. 5, Issue 11, pp. 127–150 Editors: Ada Diaconescu, Stephen Marsh, Jeremy Pitt, Wolfgang Reif, and Jan-Philipp Steghöfer Dagstuhl Reports Schloss Dagstuhl – Leibniz-Zentrum für Informatik, Dagstuhl Publishing, Germany
