This paper proposes a Web service and serviceoriented architecture (SOA) for a computer-adaptive testing (CAT) process on e-learning systems. The proposed architecture is developed to solve an interoperability problem of the CAT process by using Web service. The proposed SOA and Web service define all services needed for the interactions between systems in order to deliver items and essential d...

This paper presents a web hosting service model that provides students web hosting service in e-commerce programs. The web hosting service provides each individual student a client server environment to support the development cycle of web application development. The web hosting service consists of main service and support service. The primary service provider is technical staff. Students in e...

Web Service Discovery can be described using OWL-S. It follows web service discovery model because it has conceptual and trivial semantic web service descriptions using service profile ontology of OWL-S. The Web Service Discovery model uses Web Service matchmaking algorithm which enlarges matching techniques used in Structural Case Based Reasoning, allowing the retrieval of Web services based o...

This study examines the dimensions of web service quality based on e-customer’s expectations and perceptions. We develop operationalized web service quality constructs, and analyze their relationships with customer satisfaction and behavioral intentions in an e-business environment. The three identified dimensions of web service quality are perceived risk, web content and service convenience. A...

Classes of service are a mechanism for differentiation of service and quality of service (QoS) that incurs less overhead than custom-made Service Level Agreements (SLAs), user profiles, and other alternatives. For their formal representation for XML (Extensible Markup Language) Web Services, we have developed the Web Service Offerings Language (WSOL). A service offering in WSOL is a formal desc...

Reducing the effort required to make changes in web services is one of the primary goals in web service projects maintenance and evolution. Normally, functional and non-functional testing of a web service is performed by testing the operations specified in its WSDL. The regression testing is performed by identifying the changes made thereafter to the web service code and the WSDL. In this thesi...
