Figure 2From: Quantifying participation biases on social mediaThe proposed computational framework with the probabilistic bias quantification (Biq) model at its core. The two inputs are shown in pink. The first input is the response probabilities for each demographic subgroup gathered from N representative surveys on a given topic. The second input is the aggregated opinions extracted from social media data corresponding to those N survey questions. The output of the Biq model is the demographic distribution of the participants on SMBack to article page
