Article - Impact of service quality on user satisfaction: Modeling and estimating distribution of quality of experience using Bayesian data analysis Volume: 17 Halaman: 112–122
Quality of experience (QoE) plays a crucial role in attracting and retaining users of interactive Internet
applications. In this work, the relation between quality of service (QoS) perceived by users and the
satisfaction level of users is carefully studied. In our experiments, users encountered certain latencies
while using a photo viewing service on their mobile phone; we used the experience sampling method
(ESM) to record the satisfaction level of these users on a scale of one to five. The user opinion data are
ordinal; therefore, it is not meaningful to treat the data as metric. To address this issue, we used
Bayesian data analysis with a generalized linear model (GLM) to estimate the overall satisfaction of
the users in the form of the posterior distribution of opinions. We propose that the quality of experience
of users can be represented by opinion score distribution (OSD) instead of the mean opinion score (MOS).
