| 説明 | From: www.connectedaction.netLink: www.flickr.com/photos/marc_smith/6877168263/sizes/l/These are the connections among the Twitter users who recently tweeted the word #tableau when queried on February 13, 2012, scaled by numbers of followers (with outliers thresholded). Connections created when users reply, mention or follow one another. The data set starts on 2/6/2012 19:20 to 2/14/2012 0:48 UTC. Green lines are "follows" relationships, blue lines are "reply" or "mentions" relationships.Layout created with the "Group Layout" feature of NodeXL which tiles bounded regions for each cluster. The Harel-Koren layout algorithm positioned each vertex: en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing). Clusters calculated by the Clauset-Newman-Moore algorithm are also encoded by color.A larger version of the image is here: www.flickr.com/photos/marc_smith/6877168263/sizes/l/Betweenness Centrality is defined here: en.wikipedia.org/wiki/Centrality#Betweenness_centralityClauset-Newman-Moore algorithm is defined here: pre.aps.org/abstract/PRE/v70/i6/e066111Top most between users: @tableau@kpottermn@_tombrown_@acotgreave@joemako@mcristia@ajenstat@vizbizwiz@flyingbinary@keestimmersV1, V2, WEIGHTmagic, quadrant, 20@gartner, magic, 9#tableau, looking, 9looking, good, 9field, trip, 8trip, today, 8newport, beach, 8tour, site, 8adv, #tableau, 8#tableau, seminar, 8teach, people, 8details, soon, 8positive, customer, 8customer, survey, 8survey, feedback, 8overwhelmingly, positive, 7customers, even, 6even, more, 6more, enamored, 6top, tweeters, 5Graph Metric, ValueGraph Type, DirectedVertices, 98Unique Edges, 565Edges With Duplicates, 164Total Edges, 729Self-Loops, 85Connected Components, 19Single-Vertex Connected Components, 18Maximum Vertices in a Connected Component, 80Maximum Edges in a Connected Component, 710Maximum Geodesic Distance (Diameter), 4Average Geodesic Distance, 2.003116Graph Density, 0.060803703Modularity, 0.206315NodeXL Version, 1.0.1.199More NodeXL network visualizations are here: www.flickr.com/photos/marc_smith/sets/72157622437066929/ and here:www.nodexlgraphgallery.org/Pages/Default.aspxA gallery of NodeXL network data sets is available here: nodexlgraphgallery.org/Pages/Default.aspx?search=twitterNodeXL is free and open and available from www.codeplex.com/nodexlNodeXL is developed by the Social Media Research Foundation (www.smrfoundation.org) - which is dedicated to open tools, open data, and open scholarship.Donations to support NodeXL are welcome through PayPal: www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_bu...The book, Analyzing social media networks with NodeXL: Insights from a connected world, is available from Morgan Kaufmann and from Amazon.Marc Smith on Twitter. |
