Constructing Web-scale functional map on global social service network for workflow-as-a-service

Web services has been considered to have a tremendous impact on the web, as a potential silver bullet for supporting distributed service-based economy at a global scale. However, despite the outstanding progress their uptake on a Web-scale has been significantly less prominent than initially anticipated. The main reasons are summarized as following: "Homepage-service" era has hampered service discovery and service composition. To solve this problem, we provide a new approach for automatic service composition based on social link. We propose global social service network which is constructed by linking services based on relationship between services. We define web-scale functional map to composite service based on the global social service network using social link.
