Abstract
- One important step in dynamic web service composition is to bind concrete web services to the activities involved in the composition. Ideally, the component services are assigned such that the resulting composite web service meets the service level agreements and offers the best trade-off between the various QoS parameters. This implies the ability to express preferences related to the trade-offs. In this paper, we propose a binding-as-a-service (BaaS) approach based on a powerful, but at the same time simple and intuitive notation for specifying user preferences. The typical client of a BaaS provider is a module of a service composition framework. The service request describes the abstract composition model, the available component services and the QoS constraints and preferences. A prototype implementation of this binding-as-a-service approach validates our method. [ABSTRACT FROM PUBLISHER]
