Got what you want? Modeling expectations to enhance web QoE prediction
Andreas Sackl, Raimund Schatz · 2014
Despite strong consensus within the QoE community about the heavy influence of user expectations on quality perception and judgment, the actual integration of this factor in QoE assessment and modeling has been hitherto neglected. In this paper we demonstrate how to obtain data regarding individual users' expectations and model their QoE impact. Using two Web QoE studies as example, we show how expectation-related data is gathered via questionnaires to improve accuracy of two exponential Web QoE models.
