On Automated Composition for Web Services
The main objective of composing web services is to identify usable web services through discovery and to orchestrate or assemble selected services according to the goal specification. we formulate and study a framework to compose web services through discovery and orchestration for a given goal service. Composition algorithms without or with a goal service invocation request are developed. Two strategies are developed to tighten the goal service. Two notions of completeness are defined to measure the ability of how thorough the algorithms can find a composition.
