The document discusses the analysis of online conversations through network visualization, emphasizing the role of moderators in enhancing community engagement and communication. It presents metrics indicating that community-generated content is on the rise but highlights the importance of moderation to maintain interaction quality. Additionally, it examines the emergence of specialized subcommunities and the need for validation in discussions to ensure the richness of content.

The network must be specified. It is important to define what nodes
and edges represent.

Here (mostly): nodes => users, edges => comments

NOT involve moderators

27. Not much, but getting better

28. Not much, but getting better

Almost all posts and about two thirds of the comments are produced
by the community, not the moderators.

On the plus side, the share and number of interactions NOT involving
moderators are both growing.

31. Are specialized subcommunities
emerging?

32. Moderators removed
Modularity 0.5 (>0.4 = “high”)
Subcommunities are clearly
visible

33. Are subcommunities
specializing?
Bluer edge = more
specialization on one or few
topics,
Redder edge = no
specialization, all topics equally
discussed

34. It seems so!
(but check absolute numbers)

35. How “broad” and “deep” are my
results?

36. Topic tree
Blue research questions are
addressed by green posts, in
turn validated by red comments

37. Topic tree (detail)

38. Topic tree (detail)
No validation

39. Topic tree (detail)
Lots of validation

40. Topic tree (detail)
Broad discussion,
many points of
view

41. Topic tree (detail)
Narrow discussion

42. Some are, some are not...

43. Some are, some are not...
•
Check you are not relying on results from “narrow” and “shallow”
discussion, however you might like the content!

•
Deploy moderators to ask the community to reinforce semmeingly
important results that are not sufficiently validated

45. Now go do it!

46. A SNA module for Drupal

47. coming soon....
