Dyna is a single-agent architectural framework that integrates learning, planning, and reacting. Well known instantiations of Dyna are Dyna-AC and Dyna-Q. Here a multiagent extension of Dyna-Q is presented. This extension, called M-Dyna-Q, constitutes a novel coordination framework that bridges the gap between plan-based and reactive coordination in multiagent systems. The paper summarizes the ...

In the design of the organisation of a multiagent system the concept of role is fundamental. We informally analyse this concept through examples. Then we propose a more formal definition that can be decomposed into: the conditions that have to be satisfied to hold a role, the norms and institutional powers that apply to a role holder. Finally, we present a modal logical framework to represent t...

Different agents may have different points of view. This can be modelled using different abstract argumentation frameworks, each consisting of a set of arguments and a binary attack-relation between them. A question arising in this context is whether the diversity of views observed in such a profile of argumentation frameworks is consistent with the assumption that every individual argumentatio...

This paper details the implementation of a software framework that aids the development of distributed and self-configurable software systems. This framework is an instance of a novel integration strategy called SoSAA (SOcially Situated Agent Architecture), which combines Component-Based Software Engineering [15] and Agent-Oriented Software Engineering, drawing its inspiration from hybrid agent...

Web services requirements for means of automating the coordination of distributed heterogeneous applications have been addressed by a twopronged initiative. One has been driven by process management technologies, represented by the compositional language BPEL4WS, and the other by the Semantic Web technologies, represented by ontologies and agents. The framework presented in this paper integrate...

A lot of work is devoted to analysing architectures for coordinating the behaviour of individual agents. However, providing agents with abilities to migrate continues to be a highly challenging problem. We propose a novel multi-agent framework, called Agent-based Migration (AM). We begin by defining the principal objective, which is the migration phenomenon applied, in our case, to distributed ...

As the amount of information and communication increases dramatically new working environments must provide efficient mechanisms to maximize the benefits of these developments. In this paper a telecollaboration environment based on agent technology is proposed, which could be used as an information infrastructure for cooperative buildings or virtual enterprises. The number of communication and ...
