Abstract. In order to discover and compose relevant Web services, most Web service composition approaches require users to describe composition requirements and constraints in formal expressions. However, requirements still focus on the technical level as they require domain-specific knowledge on functional and non-functional properties. As a matter of fact, the gap between users’ high-level requirements describing business objectives and composition requirements remains a challenge in Web service composition. In this paper, we propose an end-to-end transformation approach to build a set of technical composition requirements from user high-level requirements, which are specified by an English-structured language to capture business objectives, and to specify actions that Web services can achieve.
