Web service search is an important problem in service oriented architecture that has attracted widespread attention from academia as well as industry. Web service searching can be performed by various stakeholders, in different situations, using different forms of queries. All those combinations result in radically different ways of implementation. Using a real world web service composition exa...

Dynamic web service selection is a problem in semantic web environment because of the selection of ontologies. Web services(WSs) will be the building blocks of for developing the next generation applications using the service oriented architecture(SOA). Semantic web service ontologies are more important in defining the web service identification and selection. Web service provision is the proce...

We are developing a language, Web Service Offerings Language (WSOL), for the formal specification of various constraints, management statements, and classes of service for Web Services. WSOL is an XML (Extensible Markup Language) notation compatible with WSDL (Web Services Description Language). A service offering in WSOL is a formal description of one class of service of a Web Service. It cont...

-Web Services are emerging technologies that enable application to application communication and reuse of services over Web. Semantic Web improves the quality of existing tasks, including Web services discovery, invocation, composition, monitoring, and recovery through describing Web services capabilities and content in a computer interpretable language. To provide most of the requested Web ser...

The critical issue of web services success is the ability to compose web services in order to build complex added-value services. In web service compositions both functional and non functional properties, i.e. quality of service, should be taken into account. The quality of service in web service compositions plays a vital role and has opened a wide spectrum of challenges. We survey and analyze...

From a business perspective, Web services represent a new channel for the offer as well as the acquisition of business capabilities. The full automation of the interaction process between providers and consumers is a peculiarity of the Web service channel. Beyond electronic data transfer, automation extends to all aspects of business interaction. The negotiation of terms and conditions for serv...

Businesses offer complex services to the users, which can’t be provided by a single Web Service. A Composite Web Service provides more complicated function, by composing multiple Web services. A composite service is more susceptible to failure than an atomic service. During the execution of a Composite Web Service, if one Component Service fails or becomes unavailable, the whole Composite Web S...

In current service-oriented applications, each individual Web service usually cannot satisfy users’ requests for Web services, but the functionalities of different Web services may be integrated to accomplish requested task. This process is called Web service composition, and the resulted service is called composite Web service. The discovery and composition of Web services are two important re...

Web services have been developed and deployed for GIS applications. Client-server interaction in such applications is limited by the service provider, such as ArcWeb Service. This paper will discuss the needs from service requester which lead to the exploration on the design and manipulation of Web Service interface. It is likely that GIS Web Service promotes the separation of spatial feature a...

Web Service choreography management challenges the research on Service Oriented Architectures: different from Web Service composition, where a central orchestrator process invokes the Web Service suppliers, a choreographed service is decentralized and it is based on the coordination of a set of Web Service suppliers having a partial view of the overall service. In this paper, we present a frame...
