QoS-aware services selection as a key step for web services composition has been studied widely. It could select optimal candidate services to non-functional properties for each task in abstract web service composition (WSC). Nowadays, there are lots of research work in this aspect. However, few work considers transactional constraints of WSC. We propose a novel approach which not only resolves the...
In web service composition (WSC), quality of service (QoS)-based web services selection has been a critical research issue, and many service selection methods have been presented aiming at resolving this issue, However, most of the existing methods ignore giving a risk evaluation for critical web services in WSC where transactional requirements often require compensation cost to ensure failure atomicity...
There are increasingly demanding for huge computing capabilities and complex processes managing technologies along with the development of large-scale parallel scientific computing applications. Taking ensemble prediction in climate domain for example, we discuss BPEL-based workflow for complex scientific computing management. The contributions of this paper are double-folds: on the framework side,...
The development of large-scale parallel scientific computing applications has put forward more urgent demands for powerful computing capacities and complex process managing technologies. Meanwhile, the scientific experiment processes become more and more complicated which makes it becomes a hard work for e-scientists to control the experiment analysis processes by hand. In this paper, we provide a...
Web service composition is emerging as a promising technology for supporting large-scale, sophisticated business process integration in a variety of complex e-science or e-business domains. Particularly, semantics have been proposed as a key to automatically solving the discovery and composition problem. However, most of semantic composition approaches still remain at a stage of low efficiency because...
Meteorology grid computing aims to provide scientist with seamless, reliable, secure and inexpensive access to meteorological resources. However, the vision of achieving these goals has been encountered with many challenges such as the degree of easy-to-use and the capability of seamless automation. Fortunately, the emerging semantic Web service and semantic grid technologies bring some significant...
