1. Papazoglou, M.P., van den Heuvel, W.-J.. Web services management: a survey. Internet Computing, IEEE, Vol. 9, Num. 6, pages 58-64, November/December 2005.
   Abstract: Solutions based on service-oriented architectures are promising in that they leverage common services and enable collaborative business processes that cross organizational boundaries. However, because Web services applications can span multiple hosts, operating systems, languages, and enterprises, it's problematic to measure, control, and manage application availability and performance. In addition to discussing the relationship of Web services management to traditional distributed systems management, this survey explores various Web services management approaches and their underlying architectural concepts.

2. James Pasley. How BPEL and SOA Are Changing Web Services Development. IEEE Internet Computing, Vol. 9, Num. 3, pages 60-67, 2005.
   Abstract: As the use of Web services grows, organizations are increasingly choosing the Business Process Execution Language for modeling business processes within the Web services architecture. In addition to orchestrating organizations' Web services, BPEL's strengths include asynchronous message handling, reliability, and recovery. By developing Web services with BPEL in mind, organizations can implement aspects of the service-oriented architecture that might previously have been difficult to achieve.

3. Frank E. Ritter, Richard M. Young. Embodied models as simulated users: introduction to this special issue on using cognitive models to improve interface design. Int. J. Hum.-Comput. Stud., Vol. 55, Num. 1, pages 1-14, 2001.
   Abstract: Cognitive models provide a means for applying what is known from psychology to the design of interfaces, thereby improving their quality and usability. Existing uses of models include predicting time and errors for users to perform tasks, acting as embedded assistants to help users perform their tasks, and serving as surrogate users. Treating the design of human-computer interfaces as a form of engineering design requires the development and application of user models. A recent trend is for models to be built within the fixed framework of a cognitive architecture, which has been extended by the addition of simulated eyes and hands, enabling the construction of embodied models. Being embodied allows models to interact directly with interfaces. The resulting models can be used to evaluate the interfaces they use, and serve as explanations of users' behavior. The papers in this Special Issue point to a new route for the future, one in which models built within embodied cognitive architectures provide information for the design of better interfaces.

Articles in Refereed Conferences:

1. Dimka Karastoyanova, Branimir Wetzstein, Tammo van Lessen, Daniel Wutke, Jörg Nitzsche, Frank Leymann. Semantic Service Bus: Architecture and Implementation of a Next Generation Middleware. ICDE Workshops, pages 347-354, 2007.
   Abstract: In this paper we present a middleware for the service oriented architecture, called the Semantic Service Bus. It is an advanced middleware possessing enhanced features, as compared to the conventional service buses. It is distinguished by the fact that it uses semantic description of service capabilities, and requirements towards services to enable more elaborate service discovery, selection, routing, composition and data mediation. The contributions of the paper are the conceptual architecture of the Semantic Service Bus and a prototypical implementation supporting different semantic Web service technologies (OWL-S and WSMO) and conventional Web services. Since mission critical application scenarios (for SOA) involve complex orchestrations of services, we have chosen to utilize semantically annotated service orchestrations as the applications to employ this middleware.

1. I. Foster, H. Kishimoto, A. Savva, D. Berry, A. Djaoui, A. Grimshaw, B. Horn, F. Maciel, F. Siebenlist, R. Subramaniam, J. Treadwell, J. Von Reich . The Open Grid Services Architecture, Version 1.0. ANL, IBM, Fujitsu, NeSC, CCLRC-RAL, UVa, Hitachi, Intel, HP, 2005.
   Abstract: Successful realization of the Open Grid Services Architecture (OGSA) vision of a broadly applicable and adopted framework for distributed system integration, virtualization, and management requires the definition of a core set of interfaces, behaviors, resource models, and bindings. This document, produced by the OGSA working group within the Global Grid Forum (GGF), provides a first version of this OGSA definition. The document focuses on requirements and the scope of important capabilities required to support Grid systems and applications in both e-science and e-business. The capabilities described are Execution Management, Data, Resource Management, Security, Self-Management, and Information. The description of the capabilities is at a high-level and includes, to some extent, the interrelationships between the capabilities.
