The emerging next-generation Web technologies, centered on the concept of Web services, promise to enable interactions and efficiencies that have not been experienced before. The foundation of this technology lies in the modularization and virtualization of system functions as services that: (i) can be described, advertised and discovered using (XML-based) standard languages,and (ii) interact through standard Internet protocols.

This talk outlines some of the significant achievements and opportunities in the field of service oriented computing. We will then examines interoperability challenges in service-oriented architectures. While much progress has been made toward providing basic interoperability at the messaging layer, there is still a lot to be done. Interoperability is more pronounced in service-oriented architectures than usual partly because services are typically developed by different organizations, and the difficulties created by services' autonomy and semantic heterogeneity. We highlight interoperability aspects at higher level of abstractions including content, business protocol, and policy layers. Finally, we will discuss several open research issues in facilitating large-scale interoperation among Web services.

BIO

Boualem Benatallah received his PhD degree in computer science from Grenoble University (IMAG, France). He is senior lecturer at the University of New South Wales Sydney, Australia. His research interests lie in the areas of Web service protocols analysis and management, enterprise services integration, large scale and autonomous data sharing, process modeling and service oriented architectures for pervasive computing. He has several ARC (Australian Research Council) funded projects in these areas. He was a visiting scholar at Purdue University (USA), Visiting Professor at INRIA-Loria (France), Visiting Professor at Blaise Pascal University (Clermont-Ferrand, France).

He is member of the editorial board of the International Journal of Business Process Integration and Management. He has been a Program Committee member of several conferences. He was the PC chair of several Int. workshops on Web services. He was guest editor for the special issue on E-Services of the Journal on Parallel and Distrib-uted Databases, Kluwer Academic Publishers, and for the special issue on .M-Services, Web Services for the Wireless World. of IEEE Transactions on Systems, Man, and Cybernetics. He is co-author of Interconnecting Heterogeneous Information Systems (Kluwer, 1998). He is also co-author of E-Commerce Enabling Technologies, Pearson Education, 2002. He has published widely in international journals and conferences including IEEE TKDE, IEEE TSE, IEEE Internet Computing, IEEE Network, IEEE Intelligent Systems, VLDB, PADD journals and IEEE ICDE, IEEE ICDS, WWW, ER conferences.

Aims and Scope

Web services have emerged as a key technology for rendering services over the WWW. They are interoperable across platforms and neutral to languages, which makes them suitable for access from heterogeneous environments. As a consequence of the rapid growth of web service applications and the abundance of service providers, the consumer is faced with the inevitability of selecting the "right" service provider. In such scenarios, the quality of service (QoS) becomes a benchmark to differentiate services and providers. Quality of service forms the underpinning for a broad spectrum of web service activities such as selection, scheduling, pricing and specifying service level agreements.

This workshop seeks to provide an international forum for discussion and disseminating of research in the area of web services quality. Quality is a vital and integral component for the success of the web services paradigm. The workshop will focus on a holistic view of quality that integrates the objective view of QoS in terms of metrics and the subjective perception of QoS in terms of user context awareness.

The workshop aims to foster and facilitate discussion and collaboration amongst researchers in the area of web services quality. The topics for which submissions are solicited include (but are not limited to):

• Definition of quality metrics
• Automation and validation of web services quality metrics
• Modelling of web services quality
• Quality aware enhancements to UDDI Instrumentation of Web services for QoS
• Agent-based web service architecture as a means of providing QoS attributes
• QoS in grid-based services
• Computation of web processes QoS based on web services QoS
• Semantic description of Web services QoS
• Integration of context-awareness in to web service quality specification
• Estimation and prediction of QoS levels
• Scheduling techniques to support differentiated QoS levels
• QoS driven selection and composition
• QoS driven costing and pricing of web services
• Automated generation of Service Level Agreements from QoS specifications
• Multi-level quality descriptions for web services
• QoE (Quality of Experience) and QoBiz (Quality of Business)
