Normative Multi-Agent Systems (Dagstuhl Seminar 15131)

Authors: Amit K. Chopra, Leon van der Torre, Harko Verhagen, and Serena Villata

Published in: Dagstuhl Reports, Volume 5, Issue 3 (2015)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 15131 "Normative Multi-Agent Systems". Normative systems are systems in the behavior of which norms play a role and which need normative concepts in order to be described or specified. A normative multi-agent system combines models for normative systems (dealing for example with obligations, permissions and prohibitions) with models for multi-agent systems. Normative multi-agent systems provide a promising model for human and artificial agent coordination because they integrate norms and individual intelligence. They are a prime example of the use of sociological theories in multi-agent systems, and therefore of the relation between agent theory—both multi-agent systems and autonomous agents—and the social sciences—sociology, philosophy, economics, legal science, etc. The aim of this Dagstuhl Seminar was to feature two fresh themes in broader computing and software engineering: social computing and governance. These themes are highly interdisciplinary, bringing together research strands from computing, information sciences, economics, sociology, and psychology. Further there is considerable excitement about these areas in academia, industry, and public policy organizations. Our third theme was agreement technologies, a more traditional topic but nonetheless relevant for the NorMAS community. A norm is a fundamental social construct. Norms define the essential fabric of a society. Our purpose in this seminar was to explore the connections of norms to each of the themes, especially from a computational perspective. Moreover, the seminar has been conceived for the writing of a volume titled "Handbook of Normative Multi Agent Systems" aimed to become a standard reference in the field and to provide guidelines for future research in normative multi-agent systems.

Simulation and NorMAS

Authors: Tina Balke, Stephen Cranefield, Gennaro Di Tosto, Samhar Mahmoud, Mario Paolucci, Bastin Tony Roy Savarimuthu, and Harko Verhagen

Published in: Dagstuhl Follow-Ups, Volume 4, Normative Multi-Agent Systems (2013)

Abstract
In this chapter, we discuss state of the art and future perspective of the study of norms with simulative methodologies, in particular employing agent-based simulation. After presenting the state of the art and framing the simulative research on norms in a norm life-cycle schema, we list those research challenges that we feel more apt to be tackled by the simulative approach. We conclude the chapter with the indications for the realization of a NorMAS simulation platform, illustrated by selected scenarios.

Massively multiple online role playing games as normative multiagent systems

Authors: Johansson Magnus and Harko Verhagen

Published in: Dagstuhl Seminar Proceedings, Volume 9121, Normative Multi-Agent Systems (2009)

Abstract
The latest advancements in computer games offer a domain of human and artificial agent behaviour well suited for analysis and development based on normative multi agent systems research. One of the most influential gaming trends today, Massively Multi Online Role Playing Games (MMORPG), poses new questions about the interaction between the players in the game. If we model the players and groups of players in these games as multiagent systems with the possibility to create norms and sanction norm violations we have to create a way to describe the different kind of norms that may appear in these situations. Certain situations in MMORPG are subject to discussions about how norms are created and propagated in a group, one such example involves the sleeper in the game Everquest, from Sony Online Entertainment (SOE). The Sleeper was at first designed to be unkillable, but after some events and some considerations from SOE the sleeper was finally killed. The most interesting aspect of the story about the sleeper is how we can interpret the norms being created in this example. We propose a framework to analyse the norms involved in the interaction between players and groups in MMORPG. We argue that our model adds complexity where we find earlier norm typologies lacking some descriptive power of this phenomenon, and we can even describe and understand the confusing event with the sleeper in Everquest.

Normtypologies

Authors: Harko Verhagen

Published in: Dagstuhl Seminar Proceedings, Volume 7122, Normative Multi-agent Systems (2007)

Abstract
In this extended abstract I describe some norm typolgies developed within sociololgy and social philosophy. Using these typologies we can determine the bounderies of the different approaches to normative agent systems.
