由于Web服务的体验质量（Quality of Experience of a Web Service，Web-QoE）经常由于QoS降级而恶化，因此澄清Web服务的QoE和QoS之间的关系是必要的。然而，QoS和QoE两者通常彼此具有多个方面。因此，这种关系被迫变得复杂。本文提出了一种利用路径分析和主成分分析来明确QoS和QoE之间复合关系的方法。作者进行了实验与所提出的方法，这是指定的实际三个Web服务，利用29个科目。分析结果可以澄清Web服务的QoE和QoS之间的复杂关系。因此，可以确认所提出的方法的有效性。
Since Quality of Experience of a Web service (Web-QoE) often deteriorates because of QoS degradation, it is essential to clarify relationship between QoE and QoS for the Web service. However, both QoS and QoE generally has multiple aspects each other. Consequently, the relationship is forced to be complex. This paper proposes a method of clarifying compound relationship between QoS and QoE, which adopts the path analysis and the principal component analysis. The authors performs their experiments with the proposed method, which are designated actual three Web services and utilize 29 subjects. The analytical results can clarify the complex relationship between QoE and QoS for Web services. Consequently, the effectiveness of the proposed method can be confirmed.
