SNA::Network::Algorithm::PageRank - implementation of the PageRank algorithm
use SNA::Network; my $net = SNA::Network->new(); $net->load_from_pajek_net($filename); ... $net->calculate_pageranks();
The following methods are added to SNA::Network.
Calculates PageRank values for all nodes. Stores the values under the hash entry pagerank for each node object.
You can pass named parameters to control the algorithm: iterations specifies the number of iterations to use, and defaults to 20. damping specifies the damping factor of PageRank and defaults to 0.15.
Intuitive extension of PageRank to weighted networks.
Same as above, but treating edge weights as relative probabilities for the node transitions. Stores the values under the hash entry pagerank for each node object, the same key as above!
You can pass the same parameters as above.
On a weighted network, you usually want this method's values'.
