Speeding up web service composition with volatile external information
John F. Harney, Prashant Doshi · 2008
Existing methods for composing Web services assume that compositions are fixed. However, in practice, service environments are often volatile and parameters of participating services may change during the composition. This paper introduces a novel method for composing Web services in the presence of external volatile information. Our approach, which we call the informed-presumptive is compared to previous state-of-the-art approaches for Web service composition in volatile environments. We show empirically that the informed-presumptive strategy produces compositions in significantly less time than the other strategies with lesser backtracks.
