quality of Service (QoS) is a key factor in web service advertising, choosing and runtime monitoring. web service QoS is multi-faceted, fuzzy and dynamic. Current researches focus on implementation level performance assurance, ignoring domain specific or application level metrics which are also very important to service users. Industry web service standards lack QoS expression. The support for QoS based service choice-making is very limited. We proposed an extended web service QoS model based on configurable fuzzy synthetic evaluation system. web service QoS is evaluated dynamically according to the service context. A QoS requirement description model is also given for service QoS requirement definition. An interactive web service choice-making process is described, which takes QoS as a key factor when choosing from functionally equivalent services.
