Title: "A Survey on Video Quality-of-Experience Analysis in Large-scale 
Mobile Networks"

Mr. Lin YANG


Abstract:

Nowadays, online video streaming has dominated the mobile traffic and 
become an indispensable part of our daily life. To better understand the 
quality of mobile video service from user's perspective, many user-centric 
Quality-of-Experience (QoE) studies have been conducted. Especially in 
recent years, due to the availablity of large-scale video streaming data 
set and fast development of big data processing, data-driven QoE analysis 
has drawn extensive interests in both academic research and industrial 
applications. In this article, we first introduce the background of video 
streaming service over the mobile network, in which video service quality 
assessment lays the foundation for video service optimization. Then, we 
present the development of video service quality assessment, from 
objective Quality-of-Service assessment to user-centric 
Quality-of-Experience. We put our emphasis on the data-driven QoE 
assessment and discuss the key challenges in building a reliable 
data-driven QoE systems for video service in large-scale mobile networks. 
After that, we concentrate our effort on addressing the impact of user 
diversity, which has not been considered in previous works. We introduce 
our work on a novel personalized video QoE prediction model, which embrace 
the diversity of user. Finally, we summarize our survey and discuss 
several future research directions for personalized video QoE.
