Autonomy in the Age of Knowledge Graphs: Vision and Challenges

Authors: Jean-Paul Calbimonte, Andrei Ciortea, Timotheus Kampik, Simon Mayer, Terry R. Payne, Valentina Tamma, and Antoine Zimmermann

Published in: TGDK, Volume 1, Issue 1 (2023): Special Issue on Trends in Graph Data and Knowledge. Transactions on Graph Data and Knowledge, Volume 1, Issue 1

Abstract
In this position paper, we propose that Knowledge Graphs (KGs) are one of the prime approaches to support the programming of autonomous software systems at the knowledge level. From this viewpoint, we survey how KGs can support different dimensions of autonomy in such systems: For example, the autonomy of systems with respect to their environment, or with respect to organisations; and we discuss related practical and research challenges. We emphasise that KGs need to be able to support systems of autonomous software agents that are themselves highly heterogeneous, which limits how these systems may use KGs. Furthermore, these heterogeneous software agents may populate highly dynamic environments, which implies that they require adaptive KGs. The scale of the envisioned systems - possibly stretching to the size of the Internet - highlights the maintainability of the underlying KGs that need to contain large-scale knowledge, which requires that KGs are maintained jointly by humans and machines. Furthermore, autonomous agents require procedural knowledge, and KGs should hence be explored more towards the provisioning of such knowledge to augment autonomous behaviour. Finally, we highlight the importance of modelling choices, including with respect to the selected abstraction level when modelling and with respect to the provisioning of more expressive constraint languages.

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.

Regulated MAS: Social Perspective

Authors: Pablo Noriega, Amit K. Chopra, Nicoletta Fornara, Henrique Lopes Cardoso, and Munindar P. Singh

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

Abstract
This chapter addresses the problem of building normative multiagent systems in terms of regulatory mechanisms. It describes a static conceptual model through which one can specify normative multiagent systems along with a dynamic model to capture their operation and evolution. The chapter proposes a typology of applications and presents some open problems. In the last section, the authors express their individual views on these matters.
