Common Services researched by Service Science have four major provision modes: web page mode, local client mode, web service mode and cloud service mode. Currently the most common used is Web Service mode. And now most Web Services provided by every Service Provider access and discovery strategy is still based on keyword search's UDDI. Services returned to users often can't be called. This paper will...
We present a value-driven approach capable of determining the global optimization objective of service composition to satisfy high-level value expectations. In traditional service composition methods, global and local QoS requirements and constraints are directly raised by customers, then a set of service components (web services) are selected to achieve the optimized QoS. Yet in practice, there is...
Service modeling is a critical step in describing customer requirements and designing service systems. The quality of service models determines the quality of service systems to a great extent. To analyze the service models in a way that would show deficiencies in delivering service values, we propose the idea of "value annotation" by which expected values are labeled on the functional elements...
Web services provide a complete new way of the loosely coupled service-oriented architecture and facilitate the process of application integration by encapsulating information and existing softwares. To exploit the true potential of Web services, it is vital to develop methodologies and tools for automatic Web service composition. Numerous Web service composition description languages have been developed...
Web services provide an avenue of the loosely coupled service-oriented architecture and facilitate the process of enterprise application integration by encapsulating information, software and other existing resources. To exploit the true potential of Web services, it is vital to develop technologies and tools for Web service composition. However, for most of end-users, due to the lack of the knowledge...
