Abstract
Service-Oriented Computing (SOC) describes a specific paradigm of computing that utilizes Web services as reusable components in order to develop new software applications. SOC allows distributed applications to work together via the Internet without direct human intervention. In this work, we propose a new SOC-based approach to ensure application development. This approach ensures the discovery, selection, and composition of the most appropriate Web services. With this approach, various requirements (both functional and non-functional) are specified by the developer to satisfy QoS, QoE, and QoBiz parameters and Web services are selected and composed to meet these requirements. Our approach is implemented using the Req-WSComposer (Requirements-based Web Services Composer) platform, whose functionalities are tested using an extended and enriched version of the OWLS-TC dataset, which includes around 10,830 semantic Web services descriptions. The results of our experiments demonstrate that the proposed approach enables users to extract the most appropriate composition solution that satisfies the developer's pre-determined requirements.
