  6. 6. What can you say about a conversation without reading it all? • look at the visualization
  7. 7. What can you say about a conversation without reading it all? • • look at the visualization guess what it means
  8. 8. What can you say about a conversation without reading it all? • • • look at the visualization guess what it means how would you, as community manager, react to this information?
  9. 9. What can you say about a conversation without reading it all? • • • • look at the visualization guess what it means how would you, as community manager, react to this information? “the vocalizer” of the network analysis software conveys interpretations for you
  10. 10. Very important!
  11. 11. Very important! • The network must be specified. It is important to define what nodes and edges represent.
  12. 12. Very important! • The network must be specified. It is important to define what nodes and edges represent. • Here (mostly): nodes => users, edges => comments
  13. 13. Is my team of moderators doing a good job?
  14. 14. With moderators Density 0.028 Average weighted degree 10.87 Average distance 2.3
  15. 15. No moderators Density 0.013 Average weighted degree 3.7 Average distance 3.3
  16. 16. With moderators Density 0.028 Average weighted degree 10.87 Average distance 2.3 No moderators Density 0.013 Average weighted degree 3.7 Average distance 3.3
  17. 17. Moderators rock!
  18. 18. Moderators rock! • “No user left behind”: they connect to the general conversation people that are not talking to each other.
  19. 19. Moderators rock! • “No user left behind”: they connect to the general conversation people that are not talking to each other. • They reduce the average distance between members by one hop
  20. 20. Moderators rock! • “No user left behind”: they connect to the general conversation people that are not talking to each other. • • They reduce the average distance between members by one hop They increase the average weighted degree (number of interactions on the network) from 4 to 11

  25. 25. Not much, but getting better
  26. 26. Not much, but getting better • Almost all posts and about two thirds of the comments are produced by the community, not the moderators.
  27. 27. Not much, but getting better • Almost all posts and about two thirds of the comments are produced by the community, not the moderators. • BUT A lot of the interactions involve moderators. Drop them at your own risk!
  28. 28. Not much, but getting better • Almost all posts and about two thirds of the comments are produced by the community, not the moderators. • BUT A lot of the interactions involve moderators. Drop them at your own risk! • On the plus side, the share and number of interactions NOT involving moderators are both growing.
  29. 29. Are specialized subcommunities emerging?
  30. 30. Moderators removed Modularity 0.5 (>0.4 = “high”) Subcommunities are clearly visible
  31. 31. Are subcommunities specializing? Bluer edge = more specialization on one or few topics, Redder edge = no specialization, all topics equally discussed
  32. 32. It seems so! (but check absolute numbers)
  33. 33. How “broad” and “deep” are my results?

  42. 42. 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
