The recent evolution of Internet, driven by the Web services technology, is extending the role of the Web from a support of information interaction to a middleware for B2B interactions.Indeed, the Web services technology allows enterprises to outsource parts of their business processes using Web services. And it also provides the opportunity to dynamically(More)
In this paper we propose a rule-based approach for the semi-automatic Web services composition problem, giving end-user the control to guide the overall composition process. The end-user builds the composition flow by selecting known Web service instances or constrained Web service types, called nodes, and by connecting them using a set of control/data flow(More)
A battery of relatively simple tests allows the presumptive identification of hemoglobin (Hb) variants, making unnecessary structural analysis by protein chemistry methods or DNA sequencing. The primary step in this strategy involves the use of a matrix of electrophoretic mobilities obtained under various experimental conditions. This leads to an(More)
Web service paradigm and related technologies have provided favorable means for the realization of collaborative business processes. From both conceptual and implementation points of view, the business processes are based on a centralized management approach. Nevertheless, it is very well known that the enterprise-wide process management where processes may(More)
Reliability is one of the main challenge that encounter Web servicescompositions. Due to the inherent autonomy and heterogeneity of Webservices it is difficult to predict the behavior of the overallcomposite service.Current related technologies are unable to resolve this problemefficiently. These technologies rely on two existing strongapproa-ches:(More)
Handling workflow transactional behavior remains a main problem to ensure a correct and reliable execution. It is obvious that the discovery, and the explanation of this behavior, would enable to better understand and control workflow recovery. Unfortunately, previous workflow mining works have concentrated their efforts on control flow aspects. Although(More)
Web services composition design, verification and monitoring are active and widely studied research directions. Little work however has been done in integrating these related dimensions using a unified formalism. In this paper we propose a declarative event-oriented framework, called DISC, that serves as a unified framework to bridge the gap between the(More)
Availability of a wide variety of Web services over the Internet offers opportunities of providing new value added services built by composing them out of existing ones. By integrating individual existing Web services the technology enables the provision of advanced and sophisticated services, such as allowing users to use different types of resources and(More)
