摘要：By these days, most companies are more aware of than ever in providing quality of services over the web for reasons of economy, reliability, interoperability, flexibility, and universality. Enterprise application integration may rely on B2B scenarios where severa l 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. This p aper proposes a model that makes an automatic selection of best service provider that is based on mixed context and QoS ontology for a g iven set of parameters of QoS. We particularly show how this approach can be made to support an e-business framework and how it can add dynamics to B2B interactions by automating selection among heterogeneous services. We emphasize here on one dimensional quality of services. The approach is illustrated through a purchasing scenario to demonstrate consistency and effectiveness of the proposed method
