  • The network of connections among people who tweeted “#My2K” over the 1-day, 21-hour, 39-minute period from Sunday, 06 January 2013 at 03:30 UTC to Tuesday, 08 January 2013 at 01:09 UTC.
  • The graph represents a network of 268 Twitter users whose recent tweets contained "#cmgrchat OR #smchat. The network was obtained on Friday, 18 January 2013 at 15:44 UTC. There is an edge for each follows relationship. There is an edge for each "replies-to" relationship in a tweet. There is an edge for each "mentions" relationship in a tweet. There is a self-loop edge for each tweet that is not a "replies-to" or "mentions". The tweets were made over the 3-day, 21-hour, 15-minute period from Monday, 14 January 2013 at 18:23 UTC to Friday, 18 January 2013 at 15:38 UTC.
  • The graph represents a network of 1,227 Twitter users whose recent tweets contained "lumia. The network was obtained on Saturday, 12 January 2013 at 19:52 UTC. There is an edge for each follows relationship. There is an edge for each "replies-to" relationship in a tweet. There is an edge for each "mentions" relationship in a tweet. There is a self-loop edge for each tweet that is not a "replies-to" or "mentions". The tweets were made over the 5-hour, 1-minute period from Saturday, 12 January 2013 at 14:36 UTC to Saturday, 12 January 2013 at 19:37 UTC.
  • The graph represents a network of 1,260 Twitter users whose recent tweets contained "flotus". The network was obtained on Friday, 18 January 2013 at 18:26 UTC.

    • 49. Social Network Theoryhttp://en.wikipedia.org/wiki/Social_networkCentral tenetSocial structure emerges from the aggregate of relationships (ties)among members of a populationPhenomena of interestEmergence of cliques and clusters from patterns of relationshipsCentrality (core), periphery (isolates), betweenness Source: Richards, W. (1986). The NEGOPY network analysisMethods program. Burnaby, BC: Department ofSurveys, interviews, observations, log file analysis, computational Communication, Simonanalysis of matrices Fraser University. pp.7- 16(Hampton &Wellman, 1999; Paolillo, 2001; Wellman, 2001) 59
    • 50. SNA 101 • Node – “actor” on which relationships act; 1-mode versus 2-mode networks • Edge A – Relationship connecting nodes; can be directional • Cohesive Sub-Group – Well-connected group; clique; cluster A B D EB C • Key Metrics – Centrality (group or individual measure) • Number of direct connections that individuals have with others in the group (usually look at D incoming connections only) • Measure at the individual node or group level E – Cohesion (group measure) • Ease with which a network can connect • Aggregate measure of shortest path between each node pair at network level reflects average distance – Density (group measure) • Robustness of the network • Number of connections that exist in the group out of 100% possible F G – Betweenness (individual measure) • # shortest paths between each node pair that a node is on • Measure at the individual node level H I • Node roles – Peripheral – below average centrality C – Central connector – above average centrality D – Broker – above average betweenness E
