In this overview paper, we discuss the basic principles underlying service-oriented computing in general, and (Web) services in particular. We discuss the important differences between (Web) services and Web applications and other models in Internet computing. Finally, we discuss where we see the future research challenges in the area of service composition. Zusammenfassung In diesem Übersichts...

The composition of web services is a promising approach enabling flexible and loose integration of business applications. Numerous approaches related to web services composition have been developed usually following three main phases: the service discovery is based on the semantic description of advertised services, i.e. the functionality of the service, meanwhile the service selection is based...

-------------------------------------------------------ABSTRACT------------------------------------------------------------In this era of Cloud Computing and Service Architecture, it is expected that web services will proliferate the current market and business will expose their web service’s as B2B, C2B, E2E and C2C service componets, many web services offer the similar services, and the clien...

This paper presents a dynamic Web service composition algorithm based on description logic. Each input or output of the Web service request is regarded as a concept of description logic and according to the semantic similarity between concepts given the five types of description logic, we study on the dynamic composition algorithm based on service. Because the factors of service semantics and q...

Service Oriented Computing (SOC) provides a framework for the realization of loosely coupled service oriented applications. Web services are central to the concept of SOC. Currently, research into how web services can be composed to yield QoS optimal composite service has gathered significant attention. However, the number and spread of web services across the cloud data centers has increased, ...

Web service composition enables seamless and dynamic integration of Web services. The behavior of participant Web services determines the overall performance of a composition. Therefore, it is important to choose high quality services for service composition. Existing Web service selection and discovery approaches rely on non-functional aspects (also known as quality of service or QoS) e.g., re...

Deciding on web service equivalence in process-aware service compositions is a crucial challenge throughout the composition life cycle. Restricting such decisions to (activity) label equivalence, however, is not sufficient for many practical applications: if two activities and web services respectively have equivalent labels, does this necessarily mean they are equivalent as well? In many scena...

Web Services and Service-Oriented Architecture in general are promising concepts to overcome difficulties such as heterogeneity, scalability, etc. In this paper we present an algebraic structure of Web Services which assist users in Web Service composition and formal description of their services. Using relation algebra, tests and iteration offer the possibility of an automatic composition of W...

A great deal of recent web-related research has concentrated on automated web service composition. The main advantage of web services technology is the possibility of creating value-added services by combining existing ones to achieve customized tasks. How to combine these services efficiently into an arrangement that is both functionally sound and architecturally realizable is a very challengi...

In this era of Cloud Computing and Service Architecture, it is expected that web services will proliferate the current market and business will expose their web service’s as B2B, C2B, E2E and C2C service componets, many web services offer the similar services, and the clients application will demand more value added services and informative services rather than those offered by single entity ,o...
