I implemented two versions of the algorithm in Python, both inspired by the sparse fast solutions given in Cleve Moler's book, Experiments with MATLAB. The power method is much faster with enough precision for our task. Personalized PageRank I modified the algorithm a little bit to be able ...
There is no need to normalize these as the PageRank algorithm already does this. It will convert each personalization value to a percentage of the sum for all nodes (this is imperfect because our Ahref data aren’t unique counts per URL, but it works well enough to get a general idea)...
