3. methodology
The PageRank based methodology we use to
extract influencers on a particular topic (tweets
mentioning #cybersecurity or “cybersecurity” in
this case) takes into account the number and
quality of contextual references that a user
receives.
These calculations are independent of a user's
number of followers, but we do filter our lists
based on how much a user is engaged in the
conversation and the influence they drive through
their networks.

outlines influencer identification.
