Automated context-aware adaptation of web service executions

Abstract

The increasing popularity of Web services for application integration has strengthened the need for automated Web service composition and joint execution. Although there has been considerable research on Web service composition, very little has been studied about Web service execution, with the possible exception of Web service choreography languages. In this paper we focus our attention on Web service execution adaptation, and briefly summarize our earlier work on modeling adaptation using context ontologies. We then extend our earlier work and show how the adaptation process can itself be automated via the determination of the affected instances of the adapted Web service instances. We also present an algorithm for automated workflow adaptation that makes use of the contextual information via the context ontologies. © 2006 IEEE.
