Services are considered to have had a tremendous impact on the Web as a potential silver bullet for supporting a distributed service-based economy on a global scale. However, despite the outstanding progress, their uptake on a Web scale has been significantly less than initially anticipated. Isolated service islands without links to related services have hampered service discovery and composition. In this paper, we propose a methodology to drive innovation from isolated service islands into a global social service network to connect the service islands for Workflow-as-a-Service. First, we propose Linked social service-specific principles based on Linked data principles for publishing services on the open Web as linked social services, and suggest a new platform for constructing global social service network. We then propose an approach to enable exploiting the global social service network, providing Workflow-as-a-Service. Finally, experimental results show that Linked social service can solve the service composition problem by enabling providing Workflow-as-a-Service based on the global social service network, and has the potential to be the next wave of services.
