Semantic Web Fred, SWF for short, is a context-independent, goal-driven system for automated execution of tasks that are delegated to electronic representatives along with dynamic service usage. A task is assigned to an agent for automated resolution, represented as a Goal. This is used to determine potential partners for collaborative task resolution, and for discovery of suitable goal-resolving services that can be internal implementations as well as external Semantic Web Services. The SWF technology integrates agent technology, ontologies, and Semantic Web Service technologies - the technological building blocks identified for the Semantic Web - into a coherent system. This paper describes the architecture of SWF, explains the mechanisms for establishing automated and cooperative goal resolution, and the alignment of SWF with the Web Service Modeling Ontology WSMO, a well-structured overall framework for Semantic Web Services. We also outline the contribution of SWF to the development of Semantic Web technologies.
