Abstract

A commonly cited maxim states that 'you get what you pay for'. Implicit in it is the idea that there is a strong correlation between the price paid for something, and its quality. In this paper, we examine whether that applies to crowdsourcing for QoE experiments, and if so, how. As part of a large-scale Web QoE experiment, we conducted two crowdsourced campaigns to try and understand the influence of certain website design parameters related to typography and color on the overall visual appeal of the site. The second campaign was set up to pay three times the reward of the first one. We analyze the impact of payment on a number of parameters, including ratio of reliable users and obtained MOS values, and provide recommendations for QoE modeling.
