RE: Forum Visualisations
Thanks for the postive feedback so far.

Latest videos for your viewing pleasure,

First one shows the logic behind getting the data and also some concepts that will hopefully explain the visualisations a little better.





Second one shows 2 of the visualisations of the entire forum:





PDF's are attached as well.

RE: Forum Visualisations
As usual, a very cool illustration of the forum. Keep em coming.

I may have missed the explination, but why are different members represented by different colors?

Also, just an FYI, soldieringon is no longer a member. In fact he left quite a while ago. (Just thought I'd mention it since you refered to him as a well respected member, in case the newer members were curious about him.)

Just visiting.

Agreed, very cool.
Also very surreal. I have a hard time with disassociation.

Thanks Smile

In the 'who talks to who' thread, the different colours signify modularity...or who they've talked to the most...so if you're green, you'll likely talk to green people more. Your personal colour Stark, flags you as one of the members who's interacted more with the older, veteran members of the forum than the new breed of whipper-snappers Wink But your location in the visualizaton (right in the middle) indicates that you're well connected with both the new joiners and the old farts!

Sure - I said he was well respected becuase he had rep when I looked him up. It took me hours trying to work out why he should be so popular! It's his "Introductions" thread skewing everything.

I like it, a lot! Your narration, if not necessarily Attenboroughesque, was pleasant enough. You could make more of these where you explain the basic concepts of graph theory like size, order, radius, diameter, centrality, betweeness, etc. in a familiar context.

But not sure what that modularity was all about? Do you mean clustering coefficient? Do you mean cliques?

Way to go soldieringon, looks like your seed took.

This is really interesting. I'm playing with a couple scripts in my spare time to see if I can get more data to play with.

Thanks for the positive comments...it means a lot becuase I'm no educator and was really nervous that I'd come across as patronizing or overlly-simplistic, but if you want more of these kind of 'tutorial' videos, I'm happy to do them.

This is a brilliant question! Modularity is effecitvely Cliques+, it works on both directed and undirected networks and also works on imperfect networks too...which can't be said for all clique alogrithms. Read a detailed breakdown here and less detailed here.

Clustering Coefficiant should be a perfectly valid approach to use. But for some reason it doesn't yield results as effectively as modularity within the forum visualisations. I think this is becuase of the limitations of the Neighbourhood (Ni) function. You can see what happens when I colour the 'who talks to who' visualisation using CC below.

See? - it's all very similar colours and CC seems to strugle to identify our 'communties' in the same way that modularity does.

Thanks again for the insightful quesitons.

RE: Forum Visualisations
wow this is super interesting. I watched those two videos during lunchbreak. I want to see if I can find myself on the pdf when I am home Big Grin I saw my hun in your video heh.
well done!

edit: checked now... just can't really get it bigger and clearer. It will be a mystery Big Grin
