We offer high enough resolution images to see the details. 1. Figure 1  Malik Koné committed Feb 11, 2019 23 24  ![img](images/discussion.png)  Malik Koné committed Feb 11, 2019 25  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 1st publication does not correlate strongly enough to create the link from A to B. But A's 2nd post is timely enough, although not exactly on the same topic as B's message, to create the tie A –> B drawn as a dashed arrow. In thread 2, in addition to the tie B –> A, we have a topic overlap and time proximity between C and A. This makes a the strong tie A → C.  Malik Koné committed Feb 11, 2019 26 27 28 29  2.

Figure 3 ![img](images/convis.png) 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. 4. Figure 4 ![img](images/func.png)  Malik Koné committed Feb 11, 2019 42  Graphical proposition for the function I(s,r) of the messages' interaction strength. s is the \\internal'' strength of two messages based on content, time and social network structure. r is \\external'' requirement, it is a parameter set by the observer.

Detail of \gls{vuci} conversation taking place in 2 hours. Each circle is a message, and hovering over them brings up its content. The circle's size is proportional to their content's length. Message are layered vertically by actors. On the left is an indication of the actors total messages count.  Malik Koné committed Feb 11, 2019 66 67 68 69 70  9.
