A framework for automated service composition in service-oriented architectures

Abstract

Automated service composition refers to automating the entire process of composing a workflow. This involves automating the discovery and selection of the service, ensuring semantic and data type compatibility. We present a framework to facilitate automated service composition in Service-Oriented Architectures using Semantic Web technologies. The main objective of the framework is to support the discovery, selection, and composition of semantically-described heterogeneous services. Our framework has three main features which distinguish it from other work in this area. First, we propose a dynamic, adaptive, and highly fault-tolerant service discovery and composition algorithm. Second, we distinguish between different levels of granularity of loosely coupled workflows. Finally, our framework allows the user to specify and refine a high-level objective. In this paper, we describe the main components of our framework and describe a scenario in the genealogy domain. © Springer-Verlag Berlin Heidelberg 2004.
