Composing E-Workflows Using Syntactic, Operational And Semantic Information

With the development and maturity of infrastructures that support e-services, the authors expect organizations to incorporate Web services as part of their business processes. While in some cases Web services may be utilized in an isolated form, it is natural to expect that Web services will be integrated as part of workflows. The composition of workflows to model e-service applications differs from the design of traditional workflows due to the number of Web services available during the composition process, their heterogeneity, and their autonomy. The composition process raises two main problems that need to be solved: How to efficiently discover Web services and how to facilitate their integration with the workflow host.
