Semantic Web Services (SWS) introduce a semantic layer to the current web infrastructure, enabling the automated processing of web service tasks. In the past decade, various frameworks have been proposed for designing SWS. However, few of them aimed at testing SWS. Generating test cases for SWS is challenging due to its dynamic nature and abstract views, evaluating the test cases is equally essential...
Semantic Web Services (SWS) introduce a semantic layer to the current web infrastructure, enabling the automated processing of web tasks. Different frameworks have been proposed for designing SWS, however, there has been little research in the area of testing SWS. Generating test cases for SWS is challenging due to its dynamic nature and abstract views, evaluating the test cases is equally essential...
With the rapid increase of Web Service applications, the reliability of web service and service composition has drawn particular attention from researchers and industries. Many methods for testing and verifying the reliability have been discussed, however, the existing methods are weak in test automation and therefore difficult in tackling the dynamic features of modern SOA based application. The...
With the development of Web Service composition, more and more diversified and complex business demands are satisfied. But the logical validity cannot be guaranteed. After a short view of recent research efforts of formal modeling and verification about Web Service, this paper proposes a new formal model for WS-BPEL described Web Service composition. The specification language of the model is LOTOS...
With the development of remote sensing technology, the use of remote sensing images collected by space platforms is becoming more and more pervasive. There is more and more need to distribute processing of remote sensing images. At present, WebService can figure out non-security remote sensing images network processing, but due to network transmit without non-encryption at client side, which may lead...
Web Services (WS), which are based on standard XML protocols, such as, WSDL, SOAP and UDDI, are the building blocks of Service Oriented Architecture (SOA). The aim of SOA is to automate web service tasks, such as, web service discovery, selection, composition and execution. Since XML is a syntax-based language, the automation of these tasks is still a challenge. To overcome this, web services can...
We design a component based grid architecture on Globus. The system can be partitioned into two parts: a component support Grid environment, and a distributed user access gateway. The component support environment is composed of component container and basic component support services. Component container provides component run environment and manages the lifecycle of components, supplies component...
Web services have become popular in the modern infrastructure of the World Wide Web. They aim to provide automatic discovery, selection, and invocation of required applications (services) across the internet. However, the quality assurance aspects of Web services remain a challenge. Recently, the semantic Web has been introduced as an emerging technology which emphasizes presenting the meaning of...
