چکیده
I. Problem •Let be Q = (IQ, OQ, RQ) a user query with: IQ a set of input attributes, OQ a set of output attributes and, RQ an execution risk indicating if the obtained results can be compensated (semantically undone) or not by the user. • In the registry, each Web service (WS) is described (using OWL-S) by its: functional property (i.e. set of input and output attributes), transactional property (see Figure 1).

Service Selection of Ensuring Transactional Reliability and QoS for Web Service Composition
Service-Oriented Architecture SOA provides a flexible framework of service composition. Using standard-based protocols, composite service can be constructed by integrating component services independently. As component services are developed by different organization and offer diverse transactional properties and QoS characteristics, it is a challenging problem how to select suitable component ...
متن کاملAutomating the Composition of Transactional Web Services
Composite applications leveraging the functionalities offered by Web services today are the underpinnings of enterprise computing. However, current Web services composition systems make only use of functional requirements in the selection process of component Web services while transactional consistency is a crucial parameter of most business applications. The transactional challenges raised by...
متن کاملAn Approach for Transactional QoS-driven Service Composition
In the Service Oriented Architecture (SOA) there are always over one service candidates corresponding with the criterion of the service request, which are developed by different organizations and offer diverse, Quality of Service (QoS) values and transactional properties. While many works have been done for Web service selection, designing a composite Web service to ensure not only correct and ...
متن کاملA procedure for Web Service Selection Using WS-Policy Semantic Matching
In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...
متن کاملContext-based transactional service selection approach for service composition
Building applications dynamically from individual services offered by different organizations is one of the opportunities that Service-oriented Architecture (SoA) provides. With increasing number of providers, there is a choice among several functionally equivalent services resulting in a need to select the most appropriate ones in terms of Quality of Service (QoS) and transactional properties....
متن کاملTQoS: Transactional QoS-driven Selection for Web Service Composition
Composite Web services are often long-running, loosely coupled and cross-organizational applications. For such applications, advanced support is required to ensure quality reliable execution. This paper addresses the issue of selecting and composing Web services not only according to their functional requirements but also to their behavioral properties (e.g. transactions) and QoS characteristic...
