  2. 2. Agenda 1. Why? 2. Social Network Representation 3. Tools and Visualisations
  3. 3. Why ? • New insights from social network data - patterns of activity & trends not previously known can be identified - power of the human mind is harnessed to uncover patterns of human interaction:  Outliers e.g. isolated individuals  Ego centric networks  Cliques  Network cutpoints  Boundary riders • Explore all sorts of data including combination of unstructured & structured
  4. 4. How Social Network Analysis Helps Educators • learner isolation (McDonald, Stuckey, Noakes, & Nyrop, 2005) • creativity (Burt, 2004; McWilliam & Dawson, 2009) • community formation (Dawson, 2008; Lally, Lipponen, & Simons, 2007) • Group cohesion education evaluative tool Reffay and Chanier (2002) • Social interactions in growing classes (Brooks, et al, 2009) • Social relationships between learners (Brooks, et al, 2009) Taken from SNAPP: Realising the affordances of real-time SNA within networked learning environments, Networked Learning Conference 2010
  5. 5. How ? Train of Thought Analysis • • • • • • • • A bottom-up approach Perceptual process of discovery to uncover structure Distinguish patterns,structure, relationships and anomalies Reveals indirect links Knowledge is colour coded Marketing Analyst can spot irregularities Not sure why but where does this lead Harnesses the power of the human mind Data Information Knowledge
  6. 6. Social Network Representation • Primary focus is actors & relationships # actors & attributes • Nodes (Actors) connected by Links (Ties/relationship or edge) Adjacency list • Links represent flows or transfer – material goods or information 2 1 Graph or sociogram 3 Adjacency matrix Actors 1 1 0 2 1 3 0 2 1 0 1 3 0 1 0 Relationship 1 = presence of link 0 = no direct link 1: 2 2: 1, 3 3: 2

  10. 10. How to Find a Killer using Visualisation • 1990’s Ivan Milat killed 7 backpackers making him Australia's most notorious Serial Killer • Everyone in Australia was a suspect • Enormous volumes of data from multiple sources     RTA Vehicle records Gym Memberships Gun Licensing records Internal Police records • • Police applied visualisation techniques (NetMap) to the data • Reduced the suspect list from 18 million to 230 • Further analysis with the use of additional information reduced this to 32

  14. 14. UCINET 6 • UCINET IV for DOS is free • Grab bag of techniques and procedures • Matrix centered view – rows & columns - actors – cell value - relationship • Citation – Borgatti, S.P., M.G. Everett, and L.C. Freeman. 1999. UCINET 6.0 Version 1.00. Natick: Analytic Technologies. • Network analysis requires: – ##h file contains meta data about the network – ##d file contains the actual data about the network
