Since the majority of MTurkers are not active Twitter users, to increase the size of our data, in addition to MTurk, we also directly invited random Twitter users to participate in our TAE survey.
scores that were derived by our system correlated with survey-based scores for 80.8% of participants' Big Five scores (p<0.05 and correlation coefficients between 0.05 and 0.75), for 86.6% of participants' Needs scores (p<0.05 and correlation coefficient between 0.05 and 0.8), and for 98.21% of participants' Values scores (p<0.05 and correlation coefficients between 0.05 and 0.55).
