Normative Multi-Agent Systems (Dagstuhl Seminar 18171)

Authors: Mehdi Dastani, Jürgen Dix, Harkp Verhagen, and Serena Villata

Published in: Dagstuhl Reports, Volume 8, Issue 4 (2018)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 18171 "Normative Multi-Agent Systems". Normative multi-agent systems combine models for multi-agent systems with normative concepts, like obligations, permissions, and prohibitions. As such, they promise to be a suitable model, for example for (regulated) multiagent societies, organizations, electronic institutions, autonomous agent cooperation (with humans-in-the-loop) and much more. The aim of this seminar was to bring together researchers from various scientific disciplines, such as computer science, artificial intelligence, philosophy, law, cognitive science and social sciences to discuss the emerging topic concerning the responsibility of autonomous systems. Autonomous software systems and multi-agent systems in open environments require methodologies, models and tools to analyse and develop flexible control and coordination mechanisms. Without them, it is not possible to steer the behaviour and interaction of such systems and to ensure important overall properties. Normative multi-agent systems is an established area focussing on how norms can be used to control and coordinate autonomous systems and multi-agents systems without restricting the autonomy of the involved systems. Such control and coordination systems allow autonomous systems to violate norms, but respond to norm violations by means of various sanctioning mechanisms. Therefore it is crucial to determine which agents or agent groups are accountable for norm violations. The focus of this seminar laid on how the responsibility of autonomous systems can be defined, modelled, analysed and computed.

Authors: Elena Cabrio, Graeme Hirst, Serena Villata, and Adam Wyner

Published in: Dagstuhl Reports, Volume 6, Issue 4 (2016)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 16161 "Natural Language Argumentation: Mining, Processing, and Reasoning over Textual Arguments", 17--22 April 2016. The seminar brought together leading researchers from computational linguistics, argumentation theory and cognitive psychology communities to discuss the obtained results and the future challenges of the recently born Argument Mining research area. 40 participants from 14 different countries took part in 7 sessions that included 30 talks, two tutorials, and a hands-on “unshared” task.

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.

Norms in MAS: Definitions and Related Concepts

Authors: Tina Balke, Célia da Costa Pereira, Frank Dignum, Emiliano Lorini, Antonino Rotolo, Wamberto Vasconcelos, and Serena Villata

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

Abstract
In this chapter we provide an introductory presentation of normative multi-agent systems (nMAS). The key idea of the chapter is that any definition of nMAS should preliminarily clarify meaning, scope, and function of the concept of norm. On account of this idea, we focus on three definitions and some related requirements for nMAS. For each of such definitions we propose some guidelines for developing nMAS. Second, we suggest how to relate the concept of nMAS to different conceptions of norms and how norms can be used within the systems. Finally, we identify some specific issues that open research questions or that exhibit interesting overlaps with other disciplines.

NorMAS-RE: a Normative Multiagent Approach to Requirements Engineering

Authors: Serena Villata

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

Abstract
In this paper we present a new model, called NorMAS-RE, for the requirements analysis of a system. NorMAS-RE is a new model based on the multiagent systems paradigm with the aim to support the requirements analysis phase of systems design. This model offers a structured approach to requirements analysis, based on conceptual models defined following a visual modeling language, called dependence networks. The main elements of this visual language are the agents with their goals, capabilities and facts, similarly to the TROPOS methodology [10]. The normative component is present both in the ontology and in the conceptual metamodel, associating agents to roles they play inside the systems and a set of goals, capabilities and facts proper of these roles. This improvement allows to define different types of dependence networks, called dynamic dependence networks and conditional dependence networks, representing the different phases of the requirements analysis of the system. This paper presents a requirements analysis model based on normative concepts such as obligation and institution. The NorMAS-RE model is a model of semiformal specification featured by an ontology, a meta-model, a graphical notation and a set of constraints. Our model, moreover, allows the definition of the notion of coalition for the different kinds of network. We present our model using the scenario of virtual organizations based on a Grid network.
