Abstract

We propose an automatic service composition methodology where, three levels of composition knowledge are distinguished: user level, logical level and implementation level knowledge. We use a knowledge-based software development environment CoCoViLa that enables composition throughout these three levels. A motivation for this approach is a need to overcome the complexity of service composition on very large sets of atomic services we are dealing with in our application domain. The domain concerns federated governmental information systems.
