A user driven policy selection model

Abstract

This paper introduces a model for expressing quality according to both applications and human users perspectives. Such a model, compliant with the WS-Policy framework, not only mediates between the application and human user perspectives, but is also capable of considering the different importance that the user can assign to a quality dimension. In addition, the paper introduces a policy selection model based on the adopted quality model. So a human user expresses its requirements according to a high level language and such requirements are matched against a lower level service quality specification. © 2006 Springer-Verlag.
