Empirical study on clarification of relationship between QoS and QoE for Web services by path analysis

This paper empirically studies clarification of complex relationships between hierarchical QoS and QoE for Web services with the method using the path analysis. In the experiment, the authors treat three Web services and consider 10 parameters of three-layered QoS and four QoE parameters; they suggest a new model for a path diagram. The obtained path diagrams give high goodness-of-fit, 0.916, 0.915, and 0.902, and can clarify the QoS-QoE relationships.
