The web service model provides fundamental advantages compared to the classical software usage model. But transactions in the web service market have by far not reached the expected level. A reason for the tendency of market failure is the verifiable information asymmetry and uncertainty in the web service market. Besides deficiencies on the supply side, regarding configuration, display and com...

The Web Service Modeling Ontology (WSMO) provides a conceptual framework for semantically describing Web services and their specific properties. In this chapter we discuss how WSMO can be applied for service discovery. We provide a proper conceptual grounding by strictly distinguishing between service and Web service discovery and then present different techniques for realizing Web service disc...

In this paper, we describe an approach to Web Service development and deployment that improves consistency among related Web Services and maps out a suggested pathway for the evolution of Web Service adoption. We suggest an approach that will allow developers to move from statically bound Web Services to Web Services that are dynamically discovered and consumed and ultimately leading to fully a...

Service orientation has become a buzzword in research and practice during the last years. Enterprises consider investing in service-oriented architectures to increase the reuse of their existing software and to decrease development time and costs. On the one hand, standardization committees have advanced to define many layers of technical standards that are to become the technical backbone of a...

Web Services are the server side procedures provided to the web clients and web programmers to improve the application environment. When the service search is performed respective to particular keyword, there exists number of possible web service with almost same functionality. In such case, the comparative analysis is required in terms of availability, response time and security features of a ...

The semantic Web service discovery has been given massive attention within the last few years. With the increasing number of Web services available on the web, looking for a particular service has become very difficult, especially with the evolution of the clients’ needs. In this context, various approaches to discover semantic Web services have been proposed. In this paper, we compare these ap...

Integrated value-added Web services can be developed by combining existing Web service components that are often heterogeneous in many aspects, such as having different interfaces and data encoding schemes. Web service integration also has to face the challenge that Web service components evolve frequently in response to business needs. This paper describes a three-layer-structured model for bu...

The focus of this paper is to devise a service-oriented architecture for multi-agents system (called SAM), to reach a wide adoption and routine use of agents, web services, and semantic web technologies. In order to better integrate agents, web applications and information sources in an open and distributed environment such as the Internet, a service matchmaker called middle agent is responsibl...

A Web service is a software interface that describes a collection of operations that can be accessed over the network through standardized messaging. Effective performance and quality measures of Web services on Web service electronic marketplaces should include both technical and business aspects and consider Web services as business services delivered through multiple channels. In this resear...
