Web services represent a relevant technology for interoperability. An important step toward the development of applications based on Web services is the ability of selecting and integrating heterogeneous services from different sites. When there is no single service capable of performing a given task, there must be some way to adequately compose basic services to execute this task. The manual c...

This article gives an overview of AI (Artificial Intelligence) planning techniques and discusses their application to the Web service composition problem. ∗Second, revised version, March 2005.

BACKGROUND Service users wish to be involved in care planning but typically feel marginalized in this process. Qualitative explorations of the barriers and enablers of user involvement in mental health care planning are limited. QUESTION How is user involvement in care planning conceptualized by service users and how can meaningful involvement be instilled in the care planning process? METH...

This paper presents an approach for service composition which considers QoS-based service provision schemes and variability of the QoS when planning. The QoS of a service can be stated in terms of complex service provision schemes, e.g. its s...
