Mind the (QoE) Gap: On the Incompatibility of Web and Video QoE Models in the Wild
2020 16th International Conference on Network and Service Management (CNSM), 2020Education Service Providers (ESPs) have a paramount role in the digitization of education, providing reliable devices for students and teachers and high quality Internet access at schools. In this paper, a large-scale, passive, in-device Quality of Experience (QoE) monitoring system is presented, which was deployed into a nationwide network of ...

Observations on Emerging Aspects in QoE Modeling and Their Impact on QoE Management
2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX), 2018QoE has received much attention over the past years and has become a prominent issue for delivering services and applications. A significant amount of research has been devoted to understanding, measuring, and modeling QoE for a variety of media services.

ConEx based QoE feedback to enhance QoE
Proceedings of the 2012 ACM workshop on Capacity sharing, 2012Quality of service (QoS) generally represents the performance of packet networks. Quality of experience (QoE) defines the quality perceived by end-users of applications running on these networks. This paper relates these two metrics in a novel way using the newly defined congestion exposure (ConEx) mechanism.

The QoE Evaluation Method through the QoS-QoE Correlation Model
2008 Fourth International Conference on Networked Computing and Advanced Information Management, 2008Currently, the satisfaction of user is becoming one of the most important topics concerned by the service providers. So we propose the approach method for the objective QoE measurement through the QoS parameters. The measurements and provisioning of the quality of service (QoS) are generally defined in terms of network delivery capacity and resource ...

QoE Alchemy 2.0: An improved test setup for the pecuniary bias of QoE
2013 Fifth International Workshop on Quality of Multimedia Experience (QoMEX), 2013Examining monetary aspects related to QoE research, e.g. as bias, requires specifically defined empirical testing and data analysis routines. This paper presents an advanced setup for investigating the impact of purchasing behaviors in an interactive Video-on-demand scenario, and, based on lessons learned from previous and current experiments, provides

The 25th Annual International Conference on Mobile Computing and Networking, 2019
After three highly successful editions of the Internet-QoE workshop organized at ACM SIGCOMM 2016, ACM SIGCOMM 2017, and IEEE ICDCS 2018, the goal of the fourth edition of the Internet-QoE workshop is to scale the concepts of Quality of Experience (user satisfaction, user engagement, and behavioral analysis) out of the lab studies context and bring it ...

QoE in the Web: A dance of design and performance
2015 Seventh International Workshop on Quality of Multimedia Experience (QoMEX), 2015Web services and applications are an increasingly pervasive fixture of modern life and business. This paper reports on a Web-based crowdsourced subjective assessment campaign in which we studied the effects of network performance and design aspects of manipulated Web sites on the perceived performance, perceived ease-of-use, visual appeal, as well as ...

Improving the Efficiency of QoE Crowdtesting
Proceedings of the 1st Workshop on Quality of Experience (QoE) in Visual Multimedia Applications, 2020Crowdsourced testing is an increasingly popular way to study the quality of experience (QoE) of applications, such as video streaming and web. The diverse nature of the crowd provides a more realistic assessment environment than laboratory-based assessments allow.

The unexpected QoE killer: When the network emulator misshapes traffic and QoE
2015 Seventh International Workshop on Quality of Multimedia Experience (QoMEX), 2015Packet streams observed in today's networks show a high degree of autocorrelation as successive packets tend to exhibit similar delay and loss characteristics. Network emulators used to conduct performance evaluations therefore have to support the generation of such autocorrelated streams.
