The current practice in multiagent systems typically associates the environment with resources that are external to agents and their communication infrastructure. Advanced uses of the environment include infrastructures for indirect coordination, such as digital pheromones, or support for governed interaction in electronic institutions. Yet, in general, the(More)
tuProlog is a Java-based Prolog engine explicitly designed to be minimal, dynamically configurable, and support full and clean Prolog/Java integration. In this paper, we discuss the tuProlog approach to Prolog/Java multi-paradigm integration. After tuProlog motivations and requirements, we present some examples of bidirectional Prolog/Java integration and(More)
Coordination and access control are related issues in open distributed agent systems, being both concerned with governing interaction between agents and resources. In particular, while coordination deals with enabling interaction and making it fruitful, access control is meant to control interaction to make it harmless. We argue that this twofold facet has(More)
The notion of society should play a central role in agent-oriented software engineering as a first-class abstraction around which complex systems can be designed and built as multi-agent systems. We argue that an effective agent-oriented methodology should account for inter-agent aspects by providing engineers with specific abstractions and tools for the(More)
Agent-based computing is a promising approach for developing applications in complex domains. However, despite the great deal of research in the area, a number of challenges still need to be faced (i) to make agent-based computing a widely accepted paradigm in software engineering practice, and (ii) to turn agent-oriented software abstractions into(More)
Direct interaction and explicit communication are not always the best approaches for achieving coherent systemic behaviour in the context of Multi-Agent Systems (MAS). This is evident when taking into account recent approaches dealing with environment-based coordination such as stigmergy and, more generally, mediated interaction. In this paper we propose a(More)
1 Interaction in the Agent's Space Multiagent systems are more and more becoming an ubiquitous paradigm for the design and implementation of complex software applications. Even though somehow blurred throughout the vast literature on multiagent systems, the notion of agent can be characterised by few fundamental key-points: (i) autonomy, (ii) interaction,(More)
In human society, almost any cooperative working context accounts for different kinds of object, tool, artifacts in general, that humans adopt, share and intelligently exploit so as to support their working activities, in particular social ones. According to theories in human sciences--Activity Theory and Distributed Cognition are two main examples [5,(More)
