We offer high enough resolution images to see the details. 1. Figure 1 ![img](images/evolution.png) 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 \(B\)'s late post after \(A\)'s \nth{1} publication does not correlate strongly enough to create the link from \(A\) to \(B\). But \(A\)'s \nth{2} post is timely enough, although not exactly on the same topic as \(B\)'s message, to create the tie \(A \dashrightarrow B\) drawn as a dashed arrow. In thread 2, in addition to the tie \(B \dashrightarrow A\), we have a topic overlap and time proximity between \(C\) and \(A\). This makes a the strong tie \(A \to C\).
