A conceptual architecture for semantic web enabled web services

2008

It has been recognized that due to the autonomy and heterogeneity, of Web services and the Web itself, new approaches should be developed to describe and advertise Web services. The most notable approaches rely on the description of Web services using semantics. This new breed of Web services, termed semantic Web services, will enable the automatic annotation, advertisement, discovery, selection, composition, and execution of interorganization business logic, making the Internet become a common global platform where organizations and individuals communicate with each other to carry out various commercial activities and to provide value-added services. This paper deals with two of the hottest R&D and technology areas currently associated with the Web – Web services and the semantic Web. It describes how semantic Web services extend Web services as the semantic Web improves the current Web, and presents three different conceptual approaches to deploying semantic Web services, namely, ...

Abstract—Semantic Web services will enable the semi-automatic and automatic annotation, advertisement, discovery, selection, composition, and execution of inter-organization business logic, making the Internet become a common global platform where organizations and individuals communicate with each other to carry out various commercial activities and to provide value-added services.

In recent years, manufacturing supply chains are inclined to be worldwide business activity due to economic advantage of product development and service deployment in globalized world. This worldwide nature encompasses of complex business interactions and interchange of information between geographically distributed enterprises in different business sectors. Semantic web service can provide appropriate information exchange architectures for global supply chain business operations. This paper describes the main features of an ontology-based Semantic Web Service Architecture (SWSA), for which a prototype system was built for material procurement systems of a manufacturing supply chain. Description Logics (DL) are used to represent the terminological knowledge of SWSA in a structured way. The architecture uses a hybrid knowledge-based system which consists of Structured Case-Based Reasoning (S-CBR), Rule-Based Reasoning (RBR), and a service concept matching algorithm. SWSA includes: (1) a collection of web service descriptions in Ontology Web Language-Based Service (OWL-S), (2) service advertisement using business Complex Concept (CC), and (3) a concept similarity assessment algorithm. Finally, an example of this concept similarity assessment algorithm is presented to demonstrate its functionality.

In recent years service-orientation has increasingly been adopted as one of the main approaches for developing complex distributed systems out of reusable components called services. Realizing the potential benefits of this software engineering approach requires semi-automated and automated techniques and tools for searching or locating services, selecting the suitable ones, composing them into complex processes, resolving heterogeneity issues through process and data mediation, and reduce other tedious yet recurrent tasks with minimal manual effort. Just as semantics has brought significant benefits to search, integration and analysis of data, semantics is also seen as a key to achieving a greater level of automation to service orientation. This has lead to research and development, as well as standardization efforts on semantic Web services. Activities related to semantic Web services have involved developing conceptual models or ontologies, algorithms and engines that could support machines in semi-automatically or automatically discovering, selecting, composing, orchestrating, mediating and executing services. This chapter provides an overview of the area after nearly a decade of research. The main principles and conceptual models proposed thus far including OWL-S, WSMO, and SAWSDL/METEOR-S. The main approaches developed by the research community that are able to use these semantic descriptions of services to support some of the typical activities related to services and service-based applications are described. Next, the ideas and techniques described through two applications that integrate semantic Web services technologies within real-world application are illustrated. Finally, a set of key resources is provided that would allow the reader to reach a greater understanding of the field, and are the main issues that will drive the future of semantic Web services.

The Web, the development of E-commerce, and new architectural concepts such as E-services and service oriented architectures (SOA) have created the basis for the emergence of a new networked economy. The scope of activities that business processes are expected to span has moved from intra-enterprise workflows coordinating multiple applications, to predefined inter-enterprise and B2B processes, to dynamically defined Web processes among cooperating organizations. The importance of service annotations and dynamic discovery in the E-services and SOA paradigms supports a parallel trend towards automatic inter-enterprise process integration. Components of technical aspect of the solutions involve the technologies for information exchange (from EDI to XML), software componentization (from CORBA to Web Services), and workflow coordination and collaboration. Semantics represents a new component to this mix, but it is also an integral part of its natural evolution. Semantics will provide a solid base for rich service annotation and discovery, support of scaleable architectures and dramatically increase the dynamic nature of Web processes. While enterprises have sought to apply semantics to manage and exploit data or content (for example, to support data integration), Web Processes are the way to exploit the use of semantics to develop and implement distributed applications composed of interoperable Web Services. Semantic Web Processes are semantics-enabled and empowered Web processes. This tutorial reviews the state of the art and presents what can be achieved by symbiotic synthesis of two of the hottest R&D and technology application areas: Web services and the Semantic Web, also two of the hottest areas of discussion at WWW2003. It explores the directions in which the Web services platform is evolving to support richer and more dynamic service interaction, and presents some of the promises and challenges in applying semantics to each of the steps in the Semantic Web Process lifecycle. In particular we present the role of semantics in annotation (Semantic Annotation of Web Services), discovery (Semantic Web Service Discovery), composition (Semantic Process Composition), process execution/enactment (Semantic Web Process Orchestration), and quality of service of Semantic Web Processes.
