Abstract:
Currently, web services are the preferred technology for implementation of distributed applications that follow a Service-Oriented Architecture. The promise of reduced cost and time for enabling a large range of company-wide business processes shifts the research focus towards reasoning about web service selection. This paper proposes an approach facilitating clients to select a web service among several ones with the same functionality based on their quality of service (QoS) properties. It provides a mechanism for integrated QoS assessment of web services taking into account all measured QoS properties of the client’s interest. The method estimates the strength of the mutual dependency of the QoS properties using a data set analysis of QoS values accumulated during the web service invocation. The approach is summarized in a step-by-step assessment procedure and is proved through a real web service selection scenario.
