### Images

The images in the paper are sometime small.  We offer high enough resolution images to see the details.

    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 \(A \to C\).
