Process-based composition of Web services has recently gained significant momentum for the implementation of inter-organizational business collaborations. In this approach, individual Web services are choreographed into composite Web services whose integration logics are expressed as composition schema. In this paper, we present a goal-directed composition framework to support on-demand business processes. Composition schemas are generated incrementally by a rule inference mechanism based on a set of domain-specific business rules enriched with contextual information. In situations where multiple composition schemas can achieve the same goal, we must first select the best composition schema, wherein the best schema is selected based on the combination of its estimated execution quality and schema quality. By coupling the dynamic schema creation and quality-driven selection strategy in one single framework, we ensure that the generated composite service comply with business rules when being adapted and optimized. 46 Distrib Parallel Databases (2008) 24: 45-72

“…The QoS attributes of Web Services have the utmost priority for various providers of services because of the unpredictable and dynamic nature of the web services. They include Service time [29], Reliability [3,6,7], Execution price [8,12,22,40],Availability [50],Scalability [27],Accessibility [13,24,28],Performance [9,24,28,3 3],Capacity [35],Integrity [24,28],Robustness/Flexibility [36,38],Completeness [36,38],Regulatory [ 24,28,35],Reputation [51]Cost [24,25,30,36],Accuracy [25,29,36],Transaction [28,29,35],Stability [29,36], and Security-Related QoS [9,35,46]. The challenges in Web Services are to enhance the QOS requirements to justify the requirements for quality of Web Services, and that requirement must be relevant to selected Web Services.…”

“…Rules control the business flow while event nodes enable sending and receiving different types of events. The research in (Zeng et al, 2002) presents a rule-based approach for composition of Web Services, enabling dynamic composition of Web Services with run-time activation of rules. The research in (Zeng et al, 2002) provides a declarative language for the composition of services.…”

The Integration Rules (IRules) environment provides a framework for using events and rules in the integration of EJB components. This research has investigated the extensions required to integrate Web Services into the IRules architecture and execution environment. The IRules language framework and metadata have been extended for Web Services, with enhancements to Web Service interfaces for describing services that represent object manipulation operations as well as component enhancements such as event generation, stored attributes, and externalized relationships between distributed components. Web service wrappers provide the additional IRules functionality for the enhanced Web Service interfaces, with a state management facility in the IRules environment providing persistent storage of stored attributes and externalized relationships. The IRules Web service wrappers are client-side, component-independent wrappers for Web Services, thus providing a more dynamic approach to the modification of service interfaces as well as the dynamic entry and exit of participants in the integration process.
