altc2013 Twitter NodeXL SNA Map and Report

Commentary by Stephen Downes

Here we have an analysis of the Twitter interactions during Alt-C last week. Now of course this chart is going to be incomplete - there were interactions over many other channels, such as email, Facebook and even my own conference chat in gRSShopper. But that said, the analysis is able to take the posts, identify primary contributors, and break down the interactions into a smallish set of groups (including, in G4, my talk on internet culture). "The graph is directed. The graph's vertices were grouped by cluster using the Clauset-Newman-Moore cluster algorithm. The graph was laid out using the Harel-Koren Fast Multiscale layout algorithm." When  you're taking big data, graph analysis is where it's at.
