| 説明 | From: www.connectedaction.netLink: www.flickr.com/photos/marc_smith/6933473987/sizes/l/Data set: nodexlgraphgallery.org/Pages/EditGraph.aspx?graphID=425These are the connections among the Twitter users who recently tweeted the word nicar when queried on February 26, 2012, scaled by numbers of followers (with outliers thresholded). Connections created when users reply, mention or follow one another. The data set starts on 2/19/2012 3:26 and ends on 2/26/2012 17:46 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. Clauset-Newman-Moore algorithm is defined here: pre.aps.org/abstract/PRE/v70/i6/e066111A larger version of the image is here: www.flickr.com/photos/marc_smith/6933473987/sizes/l/in/ph...Betweenness Centrality is defined here: en.Wikipedia.org/wiki/Centrality#Betweenness_centralityTop most between users: @lndata@ire_nicar@matt_kiefer@nicar_@fcoel@jaimidowdell@dancow@palewire@michelleminkoff@rosentalTop word pairs by frequency V1, V2, WEIGHT@explosion_nicar, @wasitas_de_kimy, 42@wasitas_de_kimy, @fcsharlenetaule, 42@fcsharlenetaule, @explosion_arg, 42@explosion_arg, @fcteam, 42@fcteam, rkimy, 42conferencia, ire, 38ire, nicar, 34ustedes, @explosion_nicar, 28@mundomagicokimy, @fansclublance, 28@explosion_arg, @explosion_nicar, 24#nicar, conference, 22pueden, ver, 21ver, testimonios, 21@jcrettaz, @diegocabot, 21@diegocabot, @mariantv, 21@mariantv, @laurarocha, 21@laurarocha, @rgbrom, 21@rgbrom, @grmadryn, 21nicar, conference, 21via, @lndata, 20Graph Metric, ValueGraph Type, DirectedVertices, 377Unique Edges, 5633Edges With Duplicates, 1240Total Edges, 6873Self-Loops, 254Connected Components, 51Single-Vertex Connected Components, 44Maximum Vertices in a Connected Component, 276Maximum Edges in a Connected Component, 5416Maximum Geodesic Distance (Diameter), 8Average Geodesic Distance, 2.357558Graph Density, 0.041396241Modularity, 0.329407NodeXL Version, 1.0.1.201More 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. |
