Foreign aid, human agency, and self‐reliance in the Pacific: Lessons from the pandemic

Rerekura Teaurere, Siulua Tokilupe Latu, Roxane Waegh, Mark Orams, more

Development Policy Review > 41 > S2 > n/a - n/a

Motivation Amid the highly polarized discourse on development aid in Pacific Islands, few studies explore the perspectives of local people. Missing from the literature is how the subjective experiences of Pacific Islands people responding and adapting to a sudden global disruption influence their perceptions of foreign aid. Faced by the sudden shutdown of export markets, tourism, and labour migration,...

Toward personalized and adaptive QoS assessments via context awareness

Lina Barakat, Phillip Taylor, Nathan Griffiths, Adel Taweel, more

Computational Intelligence > 34 > 2 > 468 - 494

Quality of Service (QoS) properties play an important role in distinguishing between functionally equivalent services and accommodating the different expectations of users. However, the subjective nature of some properties and the dynamic and unreliable nature of service environments may result in cases where the quality values advertised by the service provider are either missing or untrustworthy...

Adaptive composition in dynamic service environments

Lina Barakat, Simon Miles, Michael Luck

Future Generation Computer Systems > 2018 > 80 > C > 215-228

Due to distribution, participant autonomy and lack of local control, service-based systems operate in highly dynamic and uncertain environments. In the face of such dynamism and volatility, the ability to manage service changes and exceptions during composite service execution is a vital requirement. Most current adaptive composition approaches, however, fail to address service changes without causing...

Establishing norms with metanorms over interaction topologies

Samhar Mahmoud, Nathan Griffiths, Jeroen Keppens, Michael Luck

Autonomous Agents and Multi-Agent Systems > 2017 > 31 > 6 > 1344-1376

Norms are a valuable means of establishing coherent cooperative behaviour in decentralised systems in which there is no central authority. Axelrod’s seminal model of norm establishment in populations of self-interested individuals provides some insight into the mechanisms needed to support this through the use of metanorms, but considers only limited scenarios and domains. While further developments...

Formal Agent Development: Framework to System

Mark d’Inverno, Michael Luck

Lecture Notes in Computer Science > Formal Approaches to Agent-Based Systems > Frameworks and Formalization > 133-147

Much work in the field of agent-based systems has tended to focus on either the development of practical applications of agent systems on the one hand, or the development of sophisticated logics for reasoning about agent systems on the other. Our own view is that work on formal models of agent-based systems are valuable inasmuch as they contribute to a fundamental goal of computing of practical agent...

CONOISE: Agent-Based Formation of Virtual Organisations

Timothy J. Norman, Alun Preece, Stuart Chalmers, Nicholas R. Jennings, more

Research and Development in Intelligent Systems XX > Multi-Agent Systems and Recommender Systems > 353-366

Virtual organisations (VOs) are composed of a number of individuals, departments or organisations each of which has a range of capabilities and resources at their disposal. These VOs are formed so that resources may be pooled and services combined with a view to the exploitation of a perceived market niche. However, in the modern commercial environment it is essential to respond rapidly to changes...

Automated Negotiation for Grid Notification Services

Richard Lawley, Keith Decker, Michael Luck, Terry Payne, more

Lecture Notes in Computer Science > Euro-Par 2003 Parallel Processing > Topic 6: Grid Computing and Middleware Systems > 384-393

Notification Services mediate between information publishers and consumers that wish to subscribe to periodic updates. In many cases, however, there is a mismatch between the dissemination of these updates and the delivery preferences of the consumer, often in terms of frequency of delivery, quality, etc. In this paper, we present an automated negotiation engine that identifies mutually acceptable...

chapter

Structuring a Z specification to provide a formal framework for autonomous agent systems

Michael Luck, Mark D'Inverno

Lecture Notes in Computer Science > ZUM '95: The Z Formal Specification Notation > 46-62

This paper describes a project which is using Z in the field of artificial intelligence (AI) to provide a defining framework for agency and autonomy. Specifically, the use of Z has provided a means for escaping from the terminological chaos surrounding agency and autonomy that is prevalent not just in the AI community, but also in other areas of computer science. We outline how we have developed a...

chapter

Sociological Agents

Mark d’Inverno, Michael Luck

Springer Series on Agent Technology > Understanding Agent Systems > 93-125

Now that the inter-agent relationships that arise from the application of the SMART framework have been identified and analysed, the requisite deliberative qualities of such agents for effective and efficient action in order to gain this benefit can be addressed. An individual agent can achieve this, first through the appropriate use of its own capabilities, and second through the successful exploitation...

Towards a Monitoring Framework for Agent-Based Contract Systems

Noura Faci, Sanjay Modgil, Nir Oren, Felipe Meneguzzi, more

Lecture Notes in Computer Science > Cooperative Information Agents XII > Negotiation > 292-305

The behaviours of autonomous agents may deviate from those deemed to be for the good of the societal systems of which they are a part. Norms have therefore been proposed as a means to regulate agent behaviours in open and dynamic systems, and may be encoded in electronic contracts in order to specify the obliged, permitted and prohibited behaviours of agents that are signatories to such contracts...

chapter

From agent theory to agent construction: A case study

Michael Luck, Nathan Griffiths, Mark d'Inverno

Lecture Notes in Computer Science > Intelligent Agents III Agent Theories, Architectures, and Languages > 49-63

There is a growing body of work that concentrates on theoretical aspects of agents and multi-agent systems, and a complementary body of work concerned with building practical systems. However, the two have typically been unrelated. This gap between the theory and practice of intelligent agents has only relatively recently begun to be addressed. In this paper we describe the construction of an agent...

chapter

Evaluating Dynamic Services in Bioinformatics

Maíra R. Rodrigues, Michael Luck

Lecture Notes in Computer Science > Cooperative Information Agents X > Agents and Services > 183-197

In dynamic applications characterised by a variety of alternative services with the same functionality but heterogeneous results, agents requesting services must find an efficient way to select a service provider from alternatives. In this context, this paper proposes an evaluation method to analyse the outcome of dynamic service, in order to provide a guide for agents in future decision-making over...

chapter

Towards Motivation-Based Decisions for Worth Goals

Steve J. Munroe, Michael Luck, Mark d’Inverno

Lecture Notes in Computer Science > Multi-Agent Systems and Applications III > Formal Methods > 17-28

In this paper we present a motivational mechanism to generate and determine the worth of goals and to represent various constraints involved in satisfying a goal. The work builds on the smart agent framework and adds to the growing body of work that is attempting to extend the abilities of autonomous agents past the constraints of the traditional symbolic approaches to AI. The paper represents a first...

chapter

A Model of Normative Multi-agent Systems and Dynamic Relationships

Fabiola López y López, Michael Luck

Lecture Notes in Computer Science > Regulated Agent-Based Social Systems > Topic B: Norms and Institutions in MAS > 259-280

For agents, one of the advantages of being part of a society is the satisfaction of those goals whose success depends on the abilities of other agents. In turn, societies are controlled by norms and, consequently, agents must be able first to model the society in which they exist, and then to identify the different relationships, due to norms, in which they might be involved in order to act appropriately...

Analyzing Contract Robustness through a Model of Commitments

Amit K. Chopra, Nir Oren, Sanjay Modgil, Nirmit Desai, more

Lecture Notes in Computer Science > Agent-Oriented Software Engineering XI > Engineering Methods > 17-36

We address one of the challenges in developing solutions based on multiagent systems for the problems of cross-organizational business processes and commerce generally. Specifically, we study how to gather and analyze requirements embodied within business contracts using the abstractions from multiagent systems. Commerce is driven by business contracts. Each party to a business contract must...

Infrastructure Support for Agent-Based Development

Ronald Ashri, Michael Luck, Mark d’Inverno

Lecture Notes in Computer Science > Foundations and Applications of Multi-Agent Systems > 73-88

As the field of agent-based computing has continued to develop, there have been several contributions to its theoretical underpinnings, and several others to supporting the efforts of practical systems development. Yet the connection between the two has been limited at best. In this paper we aim to address these limitations through a consideration of appropriate agent infrastructure that can support...

Towards Requirements Analysis for Autonomous Agent Behaviour

Sorabain Wolfheart Lioncourt, Michael Luck

Lecture Notes in Computer Science > From Theory to Practice in Multi-Agent Systems > Regular Papers > 179-186

The importance of methodologies for the construction of agent-based systems has recently begun to be recognised, and an increase in efforts directed at addressing this concern is currently being seen. Yet the focus of the majority of such work is on the design aspects of methodology or on the higher-level aspects of analysis. Of no less importance, however, are the behavioural requirements and specification...

chapter

Argumentation Based Resolution of Conflicts between Desires and Normative Goals

Sanjay Modgil, Michael Luck

Lecture Notes in Computer Science > Argumentation in Multi-Agent Systems > Argument-Based Reasoning > 19-36

Norms represent what ought to be done, and their fulfillment can be seen as benefiting the overall system, society or organisation. However, individual agent goals (desire) may conflict with system norms. If a decision to comply with a norm is determined exclusively by an agent or, conversely, if norms are rigidly enforced, then system performance may be degraded, and individual agent goals may be...

chapter

Autonomy: A Nice Idea in Theory

Michael Luck, Mark d’Inverno

Lecture Notes in Computer Science > Intelligent Agents VII Agent Theories Architectures and Languages > Panel Summary: Autonomy —Theory, Dimensions, and Regulation > 351-353

Autonomy is perplexing. It is recognisably and undeniably a critical issue in the field of intelligent agents and multi-agent systems, yet it is often ignored or simply assumed. For many, agents are autonomous by definition, and they see no need to add the tautologous prefix in explicitly considering autonomous agents, while for others autonomy in agents is an important yet problematic issue that...
