SOA/WS Applications using Cognitive Agents working in CArtAgO Environments

In this paper we propose a programming model for designing and programming Service-Oriented Architectures (SOA) in an agent-oriented approach. In particular, the approach is meant to be useful for the design and programming of complex service-oriented systems, by providing first-class design tools to implement challenging features of nextcoming service applications. Indeed, besides autonomy, loose-coupled interactions, openness, flexibility, etc., the proposed design model promotes:  the use of a strong notion of agency, thus agents that can be defined along their mental attitudes to be fully autonomous systems, with pro-active and goal oriented abilities with respect of the achievement of their tasks; (ii) the definition artifact-based work environments where agents are meant to work and interact, thus enabling intelligent and cognitive agents to co-use, expose and manage web service technologies in a suitable functional fashion by the mean of special artifact-based infrastructures. Besides describing the basic concepts underlying the agent and artifact programming model for web services, the developing platform CArtAgO-WS is resumed along with a describing example explored to show the approach in practice.
