What is GraphRank?
GraphRank is a subset of EdgeRank. It is made up of Coefficient (or Affinity), Weight, Interactions (most likely similar to interactive Edges in EdgeRank), and Time Decay. The equation is most likely nearly identical to EdgeRank. Coefficient (or Affinity) is the relationship between users who share several interests, or have high activity between the two.
Facebook is unveiling new features at f8, we’re blogging on how the developments affect EdgeRank.

For example if two users have both watched ‘The Godfather’, we would expect the Affinity between the two users to be higher. This will create a much more dynamic measurement of Affinity between all Facebook users. Continue reading
