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> &rarr; C"/>.

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 \(A \to C\).

Convis Dashboard \citep{Hoque2016} helps explore conversations. On the left, the topics found in the forum using \gls{lda} and organized hierarchically. In the middle, the colored rectangles show a sentiment analysis for each message. Each message is linked to his author place on a semi-circle and thus creating a social network. Finally, on the right, Convis display the detail of the conversation.
