An Infrastructure for Agent Collaboration in Open Environments

In this paper, we present a service composition tool which enables specification of composite services for users with limited programming skills. We view composite services as a loose form of teamwork of service provider agents coordinated by a personal user agent. Such view enables us to use an existing hierarchical model of teamwork as the basis for service composition. An extension to the current model of teamwork is also proposed to achieve flexible and robust execution of composite services in an open environment.
