Dynamic Web Service Selection for Reliable Web Service Composition

Web service selection for transactional composition

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 propert...

Dynamic Service Composition for Wireless Web Access

This paper describes a Web proxy architecture called WebPADS, short for “Web Proxy for Actively Deployable Services.” The WebPADS was developed to enhance Web applications running on a wireless network. The WebPADS provides mechanisms to automatically locate and configure a flexible and adaptive wireless Web proxy. In addition, it provides a framework that facilitates the development of add-on ...

Service selection and transactional management for web service composition
