International Workshop on
Service Composition & SWS Challenge

General OverviewComposition of services in dynamic environments has received much interest for its potential to support Business-to-Business (B2B) or Enterprise Application Integration (EAI). One of such dynamic environments is the World Wide Web, which makes available a huge and rapidly growing number of heterogeneous services. 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 interact with them. There are many different types of architectures that have been developed around the concept of “services" - parties providing dynamic functionality to other parties. As the number of services increases so does the need for service reuse and service 'composability' - 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 is composed of two initiatives: the third edition of the Workshop on Service Composition and the fifthSemantic Web Services Challenge. This workshop aims to tackle the research problems around methods, concepts, models, languages and technology that enable 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. The workshop especially welcomes contributions that exploit rich semantic descriptions of web services for semi-automatic and automatic composition using web intelligence and autonomous agents technology. This workshop aims to bring together
researchers and industry attendees (e.g. leading modelers,
architects, system vendors, open-source projects, developers,
and end-users) 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. Invited SpeakerPresentation title: Is Semantic Technology making things worse? Preliminary answer: yes! Abstract: Since the inception of the Semantic Web and during the development of several Semantic Web technologies many interesting research areas opened up as well as many commercial enterprises started using those technologies. If all these research areas and commercial focus areas are categorized then it can be asked if essential focus areas from a computer science perspective are being left out, as if the Semantic Web community, academic or industrial, is beating around the bush. Furthermore, despite all advertising and scientific claims, the application of Semantic Web technology is making the integration problems and data heterogeneity worse to an yet unseen and unmanageable level of complexity. This presentation advocates a reevaluation of the focus of of Semantic Computing: away from a pure interface technology towards core computer science. Bio: Christoph Bussler is Staff Software Engineer at BEA Systems, Inc., working in the core WebLogic application server product development organization. Before joining BEA, Chris was architect at Cisco Systems, Inc. in San Jose, CA, USA, responsible for the service-oriented architecture at Cisco Systems' Quote-to-Cash business unit. Before taking this position he was Science Foundation Ireland Professor at the National University of Ireland, Galway in Ireland and Executive Director of the Digital Enterprise Research Institute (DERI). In addition to his role as Executive Director of DERI, Chris led the Semantic Web Services research group at DERI. Before DERI he was member of Oracle's Integration Platform Architecture Group based in Redwood Shores, CA, USA. He was responsible for the architecture of Oracle's next generation integration product providing EAI, B2B and ASP integration. Prior to joining Oracle he was at Jamcracker, Cupertino, CA, USA, responsible for defining Jamcracker's ASP aggregation architecture, Netfish Technologies (acquired by IONA), Santa Clara, CA, USA, responsible for Netfish's B2B integration server, The Boeing Company, Seattle, WA, USA, leading Boeing's workflow research and Digital Equipment Corporation (acquired by Compaq, acquired by Hewlett-Packard), Mountain View, CA, USA, defining the policy resolution component of Digital's workflow product. Chris has a Ph.D. in computer science from the University of Erlangen, Germany and a Master in computer science from the Technical University of Munich, Germany. Chris published a book titled 'B2B Integration', two books on workflow management, over 100 research papers in journals and academic conferences, he gave tutorials on several topics including B2B integration, workflow management and service-oriented architectures and he was keynote speaker at many conferences and workshops on topics like workflow management, B2B and EAI integration as well as Semantic Web. Workshop VenueSilicon Valley The workshop is to be held in conjunction with the 2007 IEEE/WIC/ACM International Conference on Web Intelligence (WI 2007). Topics
These topics indicate the general focus of the workshop, however, related contributions are welcome also. Papers for the SWS Challenge will describe how they solve the problems in the Challenge scenarios, which involve various composition problems, and actually solving them by calling the web services. Important DatesSubmissions: July 15, 2007 Organization of the WorkshopOrganizing CommiteeM. Brian Blake Charles Petrie Dumitru Roman Program CommitteeMichael Altenhofen, SAP, Germany Paper SubmissionsAll submissions should be formatted in IEEE Computer Society style with a page limit of 4 + 1 extra, and should be submitted in electronic format using the link: http://wi-consortium.org/wiiat07/scripts/ws_submit.php. All contributions will be peer reviewed by a program committee that will incorporate well recognized experts in the area of service composition. The Workshop proceedings will be published by IEEE Computer Society Press, to be indexed by EI. Please, take a look at table of contents. Agenda 09:00 Introductions The 2nd day will be held at the Stanford Gates Computer Science building in room 400. We'll look at solutions to the surprise problem.
