Web service composition (WSC) is the task of combining a chain of connected single
services together to create a more complex and value-added composite service. Quality of …

Abstract Web Services (WSs) are the most used implementation of service-oriented
architectures allowing the construction and the sharing of independent and autonomous …

In this paper, we address the issue of selecting and composing Web Services (WSs)
considering functional and Quality of Service (QoS) requirements combined with …

During the execution of a Composite Web Service (CWS), different faults may occur that
cause WSs failures. There exist strategies that can be applied to repair these failures, such …

Web Service (WS) composition consists in combining several WSs into a Composite WS
(CWS), which becomes a value-added process. In order to provide reliable and fault-tolerant …

QoS parameters can be used to characterise services or their compositions according to non-
functional criteria. We propose samplingbased techniques to accurately estimate QoS …

Abstract Existing Web Service architectures provide the basis for publishing applications as
Web Services (WSs), and for composing existing WSs to provide new functionalities. To fully …

The global transactional property of a Transactional Composite Web Service (TCWS) allows
recovery processes if a Web Service (WS) fails during the execution process. The following …

Functional as well as Non-functional specification plays important role in service
composition, discovery and selection. Among all the Non-functional specification cost is the …

Increasing number of users on web has attracted a large number of businesses to be made
available on web. The growing demand for webservices requires a systematic approach in …
