2nd International Workshop on Web Service Composition and Adaptation (WSCA-2008) Special Theme: Dynamic Services Composition and User Steering Website: (link to be provided) July 8, 2008, Honolulu, Hawaii, USA Affiliated with IEEE International Services Computing Conference 2008 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. The workshop will be held in conjunction with the IEEE Services Computing Conference. SCC is a prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of services computing, which in essence, has emerged as a new cross discipline that shapes the thinking of performing services business more efficiently and effectively. The workshop truly complements this theme of the conference. Additionally, for this year, we are including a special theme for dynamic service composition and user steering---topics in SOC research that have been lately gaining a lot of momentum in both academia and industry. We believe that the workshop presentations and discussions will not only bring out the current state of advances in service composition, adaptation and human involvement in constructing processes, but also provide valuable insights for future research and development avenues and for work-in progress in related areas. *Specific topics of interest include* - 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) *Submission guidelines* Authors are asked to submit original, unpublished research papers that are not being considered for publication in any other forum.
