论文摘要
传统上，通过使用短刺激通常代表零件或单次用法发作来评估QoE。这开了一个问题，即如何评估涉及多个用法情节的整体服务感知 - 与服务运营商相关的高度实际相关性问题。尽管对多重差异感知质量的这一具有挑战性的方面进行了最初的研究，但仍有待发现的基本质量形成过程及其因素的问题。我们在6〜天的使用期间与93名参与者一起提供了一个音频按需服务的多剧本实验。我们的工作直接扩展了先前的工作，以调查使用时间之间的时间的影响。结果显示出相似的效果---也没有统计学意义。此外，我们通过考虑观察到的饱和度来扩展多流行病判断的预测。
QoE is traditionally evaluated by using short stimuli usually representing parts or single usage episodes. This opens the question on how the overall service perception involving multiple} usage episodes can be evaluated---a question of high practical relevance to service operators. Despite initial research on this challenging aspect of multi-episodic perceived quality, the question of the underlying quality formation processes and its factors are still to be discovered. We present a multi-episodic experiment of an Audio on Demand service over a usage period of 6~days with 93 participants. Our work directly extends prior work investigating the impact of time between usage episodes. The results show similar effects---also the recency effect is not statistically significant. In addition, we extend prediction of multi-episodic judgments by accounting for the observed saturation.
