Dynamic workflow generation with semantic web services: A case study in Public Administration service provision

In this paper we present an automated workflow service composition framework for the Public Administration (PA) domain. We define a conceptual model for a Public Administration service workflow. This model can be implemented using existing web service technologies. In the PA domain complex services exist that require inputs evaluated from other services. Such a nested service type can be implemented using an automatic web service workflow composition. Semantic service discovery, which is based on service inputs and outputs, is also used. The final result is the complete service workflow that can be executed in any web service process engine. Our approach is based on a semantically enriched UDDI registry and an automated workflow composition of complex services. A real-life example of our framework is given for a complex Public Administration service in Greece.
