Understanding the heterogeneous rol. of individual. in l.rge-scal. inform.tion spreading is essential.to m.nage onl.ne behavior as wel. as its potential.offl.ne consequences. To this end, m.st existing studies from.diverse research dom.ins focus on the disproportionate rol. pl.yed by highl. connected ‘hub’ ***, we dem.nstrate here that inform.tion superspreaders in onl.ne social.m.dia are best understood and predicted by sim.l.aneousl. considering two individual.l.vel.behavioral.traits: infl.ence and susceptibil.ty. Specifical.y, we derive a nonl.near network-based al.orithm.to quantify individual.' infl.ence and susceptibil.ty from.m.l.ipl. spreading event data. By appl.ing the al.orithm.to l.rge-scal. data from.Twitter and Weibo, we dem.nstrate that individual.' estim.ted infl.ence and susceptibil.ty scores enabl. predictions of future superspreaders above and beyond network central.ty, and reveal.new insights into the network positions of the superspreaders.
