Meta-Modeling QoE

Abstract

In this paper we propose a methodological framework for modeling Quality of Experience (QoE) for media services in a generic manner. We consider QoE as a multi-dimensional concept dependent on several factors related to the service itself, its resource requirements, its users, and its context of use. As a first step, we group these factors into four factor spaces and propose a mapping of them into a QoE space. We then focus on the application of this mapping in the context of networked media services by adhering to a layered approach for modeling QoE dimensions in relation to the aforementioned QoE-affecting factors. Such an approach facilitates understanding a service’s QoE as acomposite function of the performance of the underlying network, and the actual service implementation, under constraints imposed by some of the QoEaffecting factors. In order to illustrate the applicability of the proposed methodology, we present a case study for mobile video.
