Registries play a key role in service-oriented applications. Originally, they were neutral players between service providers and clients. The UDDI Business Registry (UBR) was meant to foster these concepts and provide a common reference for companies interested in Web services. The more Web services were used, the more companies started create their own “local” registries: more efficient discov...

With the evolution of Web service technology, services will not only become increasingly sophisticated, but also move into the area of business-to-consumer and peer-to-peer interactions. Because of todays wide variety of services offered to perform a specific task, there is a need for mediation infrastructures able to support humans or agents in the eventual selection of appropriate services. I...

Web services [1] are the latest paradigm of distributed systems which are implemented as typically application programming interfaces (API) or web APIs that are accessed via HTTP and executed on a remote system hosting the requested services. The Web services are used to interact between components, programs, and applications. In this paper, we have proposed an approach to allow for support of ...

The current web services which are evolved in the telecom domain such as payment web services, Yellow pages web services, operator web services, weather web services are failed to bring down the semantic as they used to prove its syntactic description. The reason for bringing down the semantic description into already existing web services will invoke certain operations like automatic discovery...

Translating high-level business process flows--created by business analysts--to executable flows is often manual and time consuming. Service oriented architectures, enabled by Web services, show promise in enabling a more automatic translation process. While some work has been done to address this gap, the prior work does not provide flexible ways of discovering services and does not accommodat...

The Universal Description, Discovery and Integration (UDDI) registries do not have the ability to publish the QoS information, and the authenticity of the advertised QoS information available elsewhere may be questionable. We aim to refine the discovery process through designing a new framework that enhances retrieval algorithms by combining syntactic and semantic matching of services with QoS....

For instance, a CEA for developing a software product, may require specialised and cheaper services provided by different software engineers and programmers, which are remotely located and connected via the Internet. This enable companies such as Microsoft to acquire some services from programmers in India, while others from China. Using WS technologies and protocols such as SOAP, WSDL, and UDD...

This paper presents a method for merging UML models which takes place in a quality evaluation framework for Web Services (WS). This framework, called iTac-QoS, is an extended UDDI server (a yellow pages system dedicated to WS), using model based testing to assess quality. WS vendors have to create UML model of their product and our framework extracts tests from it. Depending on the results of t...

Web Services technology is quickly becoming the choice of middleware for application integration to provide interoperability among distributed heterogeneous applications and components. This is due to the fact Web Services are based on a few open, simple, and standard protocols (e.g., XML, SOAP, WSDL, and UDDI) and the ubiquitous Internet protocols, such as HTTP, for data and message transmissi...

The increasing number of Web 2.0 applications, such as wikis or social networking sites, indicates a movement to large-scale collaborative and social Web activities. Users can share information, add value to Web applications by using them or aggregate data from different sources creating Web applications (mashups) using specialized tools (mashup tools). However, Web 2.0 is not a new technology,...
