The Distribution of PageRank Follows a PowerLaw only for Particular Values of the Damping Factor
Track: Posters We show that the empirical distribution of the PageRank values in a large set of Web pages does not follow a powerlaw except for some particular choices of the damping factor. We argue that for a graph with an indegree distribution following a powerlaw with exponent between 2.1 and 2.2, choosing a damping factor around 0.85 for PageRank yields a powerlaw distribution of its values. We suggest that powerlaw distributions of PageRank in Web graphs have been observed because the typical damping factor used in practice is between 0.85 and 0.90.
