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.



By Gregory Piatetsky, March 14, 2014.

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 bit.ly/LIPsm8

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.
