2nd International Workshop on Web Service Composition and Adaptation (WSCA-2008)

Special Theme: Dynamic Services Composition and User Steering

held in conjunction with 6th IEEE International Conference on Services Computing (SCC-2008), Honolulu, USA

Workshop Description

Recent advances in networks, information and computation grids, and WWW have resulted in the proliferation of a multitude of physically distributed and autonomously developed Web services. Correspondingly, the construction and deployment of composite services by combining and reusing independently developed component services is an important capability in the emerging Web-based computing infrastructure. In particular, ongoing research in automatic and semi-automatic techniques of creating and managing service compositions is paving the way for business processes to continually evolve and be flexible--an important requirement in managing Information Technology (IT) complexity for big and small businesses. Typically, issues related to dynamic service compositions include developing approaches to handling service failures, changes in service functionalities, and changes to quality of service parameters. Other related topics include understanding external events, which are the sources of volatility in service compositions. In people-oriented service compositions, the element of human intervention further complicates the compositions and the manner in which compositions may be adapted. One example of this is user steering, which includes human involvement in interpreting dynamic compositions and making decisions on how the process will adapt to change. Exploring novel techniques such as mash-ups that support incremental and dynamic process evolution due to user steering is also an important topic of interest.

Specific topics of interest include (but not limited to):

  • Formal methods in service composition
  • Verification of service composition
  • Reuse in service composition: service compatibility and substitution
  • Ontology-based approaches to service composition
  • Adaptation and evolution of services
  • Dynamic service selection and binding
  • Self aware, self-optimizing, and self-healing Web services and compositions
  • Modeling of change in functional, non-functional, and process semantics
  • Re-planning of service compositions
  • "People activities" and "People-initiated" processes
  • Service compositions in mash-ups
  • BPEL4PEOPLE
  • Human interaction workflow patterns
  • Case studies, and applications (e.g., in e-science and scientific workflows)
