Abstract: This paper investigates dynamic Web Service selection for workflow optimisation, which involves selection from many semantically equivalent Web Services in a service-rich environment. The dynamic selection of Web Services involves discovering a set of semantically equivalent services by filtering available services based on service metadata, and selecting an optimal service based on real-time data and/or data recorded during prior executions of a service. Given that a user is aware of which services are critical to a workflow session, we focus on how these services can be discovered (based on some optimization criteria), and subsequently integrated into an existing workflow. We deal with the above issues and present an architecture and implementation for dynamic Web Service selection for optimising workflow.
