Composition of services in dynamic environments has received much interest for its
potential to support Business-to-Business (B2B) or Enterprise Application Integration
(EAI). One dynamic environment – in particular where there is a huge and. rapidly
growing number of heterogeneous services is the World Wide Web. Recent efforts to
develop ontology languages for the Web and ways of describing web services
semantically in this environment have resulted in a number of prototype systems that can
dynamically combine services and invoke them.
There are many different types of architectures that have been developed around the
concept of a “service" - parties providing dynamic functionality to other parties. As the
number of services increases so does the need for service reuse and service 'composeability'
- creation and provision of complex value-added services resulting in composite
services. Additional infrastructure may well need to be defined to support composition in
these open architectures.
This workshop aims to tackle the researach problems around methods, concepts, models,
languages and technology that enables composition of services in the context of the
WWW. Of particular interest are the methodologies that enable automatic or semiautomatic
composition of services, semantic web service web services, and e-services.
This proposed workshop aims to bring together researchers and industry attendees
addressing many of these issues, and promote and foster a greater understanding of how
the composition of services in the context of WWW can assist business to business and
enterprise application integration.

Prof. Marco Pistore will give a keynote talk at the workshop.
Marco Pistore is Associate Professor in Computer Engineering at the Department of Information and Communication Technology (DIT) of the University of Trento, where he leads the research group on Software Engineering. His current research interests are in the area of Web Services and of Business Processes Modeling. In particular, he works on the development of formal techniques supporting the specification, verification, synthesis, and monitoring of distributed business processes implemented with web service technologies. He is scientific coordinator of different research and technology transfer projects focusing on business process modeling. He has been co-chair of workshops (Workshop on WWW Service Composition with Semantic Web Services, Workshop on Service Oriented Business Process Integration) and has served in the program committee of different conferences and workshops in this area (Int. Conf. on Service Oriented Computing, Int. Workshop on Web Services and Formal Methods, Int. Workshop on Web Languages and Formal Methods, Int. Workshop on Web Service Choreography and Orchestration for Business Process Management).
Title of the presentation: Supporting the Composition of Distributed Business Processes: Research Challenges
Abstract of the presentation: Web services provide a universal basis for the integration of business processes that are distributed among the most disparate entities, both within an organization and across organizational borders. One of the major challenges for industry-wide adoption of Web services is the automated composition of distributed business processes, i.e., the development of techniques and tools supporting an effective, reliable, low-cost, and time-efficient composition of distributed business processes. Such tools should provide an automated, transparent, and user centered support to the entire business process life-cycle, from analysis to execution. They should automatically perform the time consuming and error prone task of analyzing business processes in detail, selecting and composing suitable Web services, detecting problems in the interactions, monitoring execution step by step, and so on. They should operate in a transparent and user centered way by suggesting solutions that can be adopted, refused, or refined by business analysts, designers, and programmers. In the talk we will discussion on some of the main research challenges and on the ongoing attempts to propose solutions in this scenario. We will focus in particular on the role that semantic annotations can play in supporting the automation of tasks such as verification, synthesis and monitoring of distributed business processed.
A special session is organized at the workshop; it is primarily meant for dissemination of the results of a currently running service composition related project - Adaptive Service Grid project.

Title:ASG: Towards the Adaptive Semantic Services Enterprise
Abstract:Over the last few years concepts, methods and tools for semantic services architectures gained significant interest in the research community. Although several promising approaches (e.g.: OWL-S or WSMO/L/X) exist, they are hardly leveraged in real world business solutions. The level of acceptance falls short of expectations as an architectural framework for adaptive services discovery, composition, and enactment is missing. Such an architectural framework, based on strong standards and taking up recent research results, could be the starting point for a flexible implementation of real world business solutions.
The platform architecture of the Adaptive Services Grid (ASG) project has the potential to be the basis for such an architectutal framework. This presentation gives an overview of the platform architecture. Key features and benefits of the platform will be demonstrated using a real world usage scenario.
