Abstract

In Web service compositions the number of component ser- vices that need to be aggregated may be large and dyn- amically changing. Web service (WS) compositions require the capability to dynamically adapt to changes that may occur at runtime, including changes in the environment and in the component services themselves. Service composers must be able to respond swiftly to changed trustworthiness (TW) requirements and capabilities of service compositions, where those changes may not be easily predictable. With the availability of alternative services providing the same functionality as those already integrated in a service com- position, service composers can take advantage of this by dynamically replacing degrading or unsatisfactory compo- nents. This paper provides techniques and an approach to dynamically detect and replace component services based on their trustworthiness.
