Agents on the Web (Dagstuhl Seminar 23081)

Authors: Olivier Boissier, Andrei Ciortea, Andreas Harth, Alessandro Ricci, and Danai Vachtsevanou

Published in: Dagstuhl Reports, Volume 13, Issue 2 (2023)


Abstract
Recent standardization on the Web of Things and (Social) Linked Data unlocks new practical use cases and new opportunities for research on Web-based multi-agent systems. While existing research on multi-agent systems can contribute to engineering adaptive and flexible Web-based systems, increased deployment of systems following the recent standards can bring new insight into engineering large-scale and open multi-agent systems. These developments motivate the need for a broader perspective that can only be achieved through a concerted effort of the research communities on Web Architecture and Web of Things, Semantic Web and Linked Data, and Autonomous Agents and Multi-Agent Systems. Thus, the main objective of the Dagstuhl Seminar 23081 on Agents on the Web was to investigate these new research opportunities, to support the transfer of knowledge and results across the different communities, and to create a network of leading scholars and practitioners around these topics. This report documents the seminar’s program and outcomes. To continue the joint work after the seminar, the seminar participants created the W3C Autonomous Agents on the Web (WebAgents) Community Group.

Autonomous Agents on the Web (Dagstuhl Seminar 21072)

Authors: Olivier Boissier, Andrei Ciortea, Andreas Harth, and Alessandro Ricci

Published in: Dagstuhl Reports, Volume 11, Issue 1 (2021)


Abstract
The World Wide Web has emerged as the middleware of choice for most distributed systems. Recent standardization efforts for the Web of Things and Linked Data are now turning hypermedia into a homogeneous information fabric that interconnects everything - devices, information resources, abstract concepts, etc. The latest standards allow clients not only to browse and query, but also to observe and act on this hypermedia fabric. Researchers and practitioners are already looking for means to build more sophisticated clients able to meet their design objectives through flexible autonomous use of this hypermedia fabric. Such autonomous agents have been studied to large extent in research on distributed artificial intelligence and, in particular, multi-agent systems. These recent developments thus motivate the need for a broader perspective that can only be achieved through a concerted effort of the research communities on the Web Architecture and the Web of Things, Semantic Web and Linked Data, and Autonomous Agents and Multi-Agent Systems. The Dagstuhl Seminar 21072 on "Autonomous Agents on the Web" brought together leading scholars and practitioners across these research areas in order to support the transfer of knowledge and results - and to discuss new opportunities for research on Web-based autonomous systems. This report documents the seminar’s program and outcomes.

From Agents to Artifacts Back and Forth: Purposive and Doxastic use of Artifacts in MAS

Authors: Michele Piunti and Alessandro Ricci

Published in: Dagstuhl Seminar Proceedings, Volume 8361, Programming Multi-Agent Systems (2008)


Abstract
Recent approaches in Multi-Agent Systems are focusing on providing models and methodologies for the design of environments and special purpose tools supposed to scale up complexities. Among others, the Agents and Artifacts (A&A) approach introduced the notion af artifact as first class abstraction providing agents with external facilities, services and coordination medium explicitely conceived for easing their activities. In this paper we analyse A&A systems by focusing on the functional roles played by artifacts. In particular, we here investigate the function of artifacts once they are employed in the context of societies of cognitve agents, i.e. agents capable to reason about their epistemic and motivational states. In this context, a twofold kind of interactions is envisaged. On the one side, artifact rapresentational function allows agent to improve epistemic states, i.e., by representing and sharing strategic knowledge in the overall system (doxastic use ). On the other side, artifacts operational function allows agents to improve the repertoire of actions, i.e., by providing additional means which can be purposively triggered by agents to achieve goals (operational use ). Some of the outcomes of this approach are discussed along with test cases showing agents engaged in goal-oriented activities relying on the transmission of relevant knowledge and the operations provided by artifacts.
