The effect on an actual conversation can be observed
by noting the cluster in the upper right of subfigure 3(a)
surrounding post 104. This cluster represents “greeting”
messages within the chat session (e.g. posts containing
“hello,”“hi,” etc.). All such messages within the test block
were linked in the same cluster, regardless of when they
occurred within the session. In subfigure 3(b), we can see
that the cluster is smaller, with some links—34!74 and
130!173—removed from the initial grouping. This occurred
due to those posts being part of a separate conversation,
thus separated temporally from the others.
