摘要：In this paper, the authors continue the study of Web service selection based on both the context and the QoS ontology and they use the same architecture proposed in the last paper that makes an automatic selection of best service provider that is based on mixed context and QoS ontology for a given set of parameters of QoS. The question is, how upon a request; the system chooses a service among several candidate services offering a capability satisfying its requests? The Quality of service presents the key factor to solve this problem. The idea is to extend on multi dimensional QoS and we emphasize on the effect of increasing the number of services (higher than seven) on the process of selection of web services. Finally, some experiments are run so to demonstrate consistency and effectiveness of the proposed method.
