Page rank algorithm

Good morning,
can anyone help me? How we can use page rank algorithm for detection of anomalies ?

Maybe this books will give an answer on your problems:

A good way to look for anomalies is to run page rank and then examine the nodes that are "outliers" -- meaning anything more than 3 standard deviations away from the mean, or even just the highest percentiles. If you'd like to get a sense of the distribution of your data, you can run pagerank in the .stats mode with CALL gds.pageRank.stats -- see the docs for more details -
