Illustration of how the strength of actors' ties (or links) varies as a function of time and topic overlap. Thread 1 corresponds to actor-topic dynamic (\ref{eq:1a}) where <img src="<https://latex.codecogs.com/svg.latex?B"/>>'s late post after <img src="<https://latex.codecogs.com/svg.latex?A"/>>'s \nth{1} publication does not correlate strongly enough to create the link from <img src="<https://latex.codecogs.com/svg.latex?A"/>> to <img src="<https://latex.codecogs.com/svg.latex?B"/>>. But <img src="<https://latex.codecogs.com/svg.latex?A"/>>'s \nth{2} post is timely enough, although not exactly on the same topic as <img src="<https://latex.codecogs.com/svg.latex?B"/>>'s message, to create the tie <img src="<https://latex.codecogs.com/svg.latex?A> \dashrightarrow B"/> drawn as a dashed arrow. In thread 2, in addition to the tie <img src="<https://latex.codecogs.com/svg.latex?B> \dashrightarrow A"/>, we have a topic overlap and time proximity between <img src="<https://latex.codecogs.com/svg.latex?C"/>> and <img src="<https://latex.codecogs.com/svg.latex?A"/>>. This makes a the strong tie <img src="<https://latex.codecogs.com/svg.latex?A> → C"/>.
