The achievement of common objectives in multi-agent systems is only possible through interaction and coordination; in order to implement both aspects in a effective manner, rules to direct the behavior of a group of agents are necessary, however, existing rules are usually static, inflexible, and inappropriate for large systems, where dynamic interaction takes place. We propose modeling agent behavior...
Given the dynamic interaction presented in multiagent systems, the occurrence of exceptions in interaction protocols is frequent, and therefore a critical issue. However, current approaches for designing interaction protocols lack semantics to direct the exchange of messages, when exceptions are raised. Here, we propose modeling exception handlers by means of obligations, which are social norms that...
We deal with composition of semantic web services to which access is controlled by agents. We propose a conversation-based web service composition method. We conceive web services as actions with preconditions and effects, expressed in terms of social norms, particularly obligations. We argue that the inclusion of obligation-based agents' conversations aide to lead the composition of services. In...
Collaboration among independent systems to achieve a common objective, which a system alone could not accomplish by itself, requires dynamic composition of the participant systems, in addition to mechanisms for leading the interaction of the resultant system of systems. Here is proposed to model system of systems using a multi-agent system approach, where agents represent stakeholders of the systems...
