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.展开更多

The contextual adaptation well explains the characteristics of dynamic contextual development in diplomatic escort interpreting. It is helpful for interpreters to understand that the choice-making was constrained by different contexts in diplomatic interpreting. In addition, interpreters should adapt to the various factors of the context thus can make flexible and appropriate choices in delivering target language in order to promote the quality of interpretation and achieve the satisfactory communicative effect.展开更多
