Context of qos In Web Service Selection

In the recent year, web service selection is becoming more and more prominent due to the large impact the web service in e-commerce.In selecting best services, several candidate services with similar capabilities are provided by different service providers. The question is, how upon a request over a B2B integration scenario, the system chooses a service among several candidate services offering a capability satisfying its requests? The Quality of service presents the key factor to answer this question. In this paper, we continue our work, we emphasize on the effect of increasing the number of qualities (higher than three), and the effect of increasing the number of services (higher than six) on the process of selection of web services based on both context and the QoS ontology for multi dimensional QoS. Finally, some experiments are run so to demonstrate consistency and effectiveness of the proposed method.
