With the rapid growth of service volumes and types, discovering services in an efficient and accurate manner has become a significant challenge in service computing. Service clustering is an important technology to improve the efficiency of service discovery. In this paper, we propose a new service clustering approach, which starts from service documents and is based on the functional semantics of...
An external web service may evolve without prior notification. In the course of the regression testing of a workflow-based web service, existing test case prioritization techniques may only verify the latest service composition using the not-yet-executed test cases, overlooking high-priority test cases that have already been applied to the service composition before the evolution. In this paper, we...
Many web services represent their artifacts in the semi-structural format. Such artifacts may or may not be structurally complex. Many existing test case prioritization techniques however treat test cases of different complexity generically. In this paper, we exploit the insights on the structural similarity of XML-based artifacts between test cases, and propose a family of test case prioritization...
Dynamic service compositions pose new verification and validation challenges such as uncertainty in service membership. Moreover, applying an entire test suite to loosely coupled services one after another in the same composition can be too rigid and restrictive. In this paper, we investigate the impact of service selection on service-centric testing techniques. Specifically, we propose to incorporate...
This paper proposed a Web Service dependency model, which is not limited to specific Web Service model and expression language. Web Services dependency connections are considered as an important part for dynamic Web Service composition planning. Dependent relationships between Web Services are depicted, and novel optimal service composition methods are presented. Results indicate that accuracy of...
Industrial cluster has been developing very quickly in China. However, most of them are low-cost-based clusters that are composed of small-medium enterprises. In this paper, we present an on-demand information service platform for small-medium enterprise clusters and propose the component-based loosely-coupled service-oriented architecture for this platform. Several key techniques such as application...
