Abstract

In this paper we define a concept of service model, and introduce hierarchical service models suitable for large service parks. We describe a method for handling higher-order workflows that we use for automatic composition of services. We give a description of a specification language suitable for representing hierarchical service models. We introduce two kinds of ontologies: service ontologies and the user ontologies, and demonstrate their usage in our experiments on Estonian e-government information system.
