KDnuggets Twitter Social Network

We examine KDnuggets Twitter social network, created by NodeXL, a free, open-source template for Microsoft Excel for social network analysis.

I am grateful to Marc Smith, @marc_smith, for generating the following network graph which represents a network of Twitter users whose tweets contained "kdnuggets" from Jan 1 to Feb 3, 2014.

NodeXL NodeXL is a free, open-source template for Microsoft Excel and is supported by donations from users.

NodeXL automatically generated highlights (top twitters and hashtags) for this graph are in NodeXL SNA gallery

KDnuggets Twitter Social Network

Here are some human understandable highlights. The graph shows
  • one very large cluster G1, with top words: data kdnuggets science bigdata analytics top scientist find learning,
  • a medium size connected cluster G2, with a major role by @kirkdborne (Kirk D. Borne, Prof. of Astrophysics at GMU and a leading data scientist),
  • cluster G3 which has many unconnected components,
  • small clusters G4-G9 where a central role is played by one leading tweeter, including @ibmbigdata, @yvesmulkers, @tomhcanderson, @peteskomoroch
  • and a bunch of micro-clusters.
