Weighted Kendall tau rank distance of static Katz index and online methods by sampling to simulate concept drift over Students, Enron, Facebook and Tumblr data. Static Katz index has β=0.01. The Weighted Kendall tau curves for temporal Katz centrality with \(c=\frac {1}{|E|}\) are green, with \(c=\frac {10}{|E|}\) are red, with \(c=\frac {100}{|E|}\) are purple, and for temporal PageRank are blue dashed. Noise in temporal Katz centrality is due to the effect of the most recently selected edges. The two vertical bars mark the time of the concept drift, when a new sampling distribution is used to generate the temporal edges
