Characterizing propagation probabilities.
(a,b) Time stamps of positive examples (retweeting behaviors) on two random edges. Each vertical line represents a retweeting behaviors occurring with the time stamp marked on the horizontal axis. (c,d) Positive (retweeting) and negative (neglecting) examples on those two edges. Vertical lines in upper half represent positive examples, while those in lower half represent negative ones. It shows an obvious tendency that most positive examples are concentrated on the left zone, i.e., most retweeting behaviors occur with short latency. The tendency is stronger on (c) than that on (d). (e) Distribution of latency of retweeting behaviors over all edges. (f) Ratio of positive examples upon all examples on all edges with respect to the associated latency, demonstrating the power-law interdependence between the propagation probability and the latency.
