Making sense of the networked audience: The case of Facebook
- Dr. Bernie Hogan is a Research Fellow at the Oxford Internet Institute
Social media sites are excellent at gathering friends, but not so great at making sense of them. This leads to social information overload: too many ties, too much information and too much tedium. There is a great deal of information latent in these friendships that can be used to make sense of our networks, both spatially and relationally. Particularly through the use of social network analysis (SNA), we can discover hidden influencers and coherent clusters. This talk will give an overview of some concepts of social network analysis and demonstrate how these can be applied to online social media sites.

Bernie will use as case study his ongoing fieldwork on Facebook with Microsoft Research that demonstrates mismatches between the way individuals organize their online friendships and the way that order emerges from the friendships naturally. These findings will be distilled into some general principles that can be applied to social network sites generally.

LSS'09 Keynote Making Sense Of The Networked Audience, Dr B Hogan

  1. 1. Making sense of the networked audience: The case of Facebook Bernie Hogan, PhD Research Fellow, Oxford Internet Institute University of Oxford Local Social Summit, Latitude 51.50015, Longitude -0.12624 November 3, 2009
  2. 2. A preamble: Why Local?

  7. 7. Wellman’s Networked Individualism Door-to-door People Place-to-place Mail and landlines Person-to-person Email and profiles
  8. 8. The particular case of a peculiar age Person-to-person networking does not undermine distance. But it makes distance secondary to specific social relationships. Each individual has their own unique relationships. Like a thumbprint. We live in an age of access. To be local is to be accessible.
  9. 9. The paradox of convenience Everyone is somewhere, no one is everywhere

  16. 16. Where does sociology fit?
  17. 17. Because you can never have too many irrelevant friends
  18. 18. Reasons for friends on SNS 1. Actual friends 2. Acquaintances, family members, colleagues 3. It would be socially inappropriate to say no because you know them 4. Having lots of Friends makes you look popular 5. It’s a way of indicating that you are a fan (of that person, band, etc.) 6. Your list of Friends reveals who you are 7. Their Profile is cool so being Friends makes you look cool 8. Collecting Friends lets you see more people (Friendster) 9. It’s the only way to see a private Profile (MySpace) 10. Being Friends lets you see someone’s bulletins and their Friends-only blog posts (MySpace) 11. You want them to see your bulletins, private Profile, private blog (MySpace) 12. You can use your Friends list to find someone later 13. It’s easier to say yes than no. Source: danah boyd 19

  21. 21. So why bother? Person-to-person networks need access controls. Social network sites fill this niche...poorly. Nevertheless, there’s gold in them thar’ hills.

  23. 23. And networks can help simplify Friends of friends are not randomly scattered, but clustered in coherent locales. Community detection can isolate these groups.
  24. 24. Friend lists Tedious and incoherent
  25. 25. Greedy Community Large swaths of Sense
  26. 26. Eigenvector Community Well partitioned, but overwhelming
  27. 27. Current tools to leverage networks on Facebook • Touchgraph • Nexus • Friendwheel • Mysocnet (Mine) • http://apps.facebook.com/mynet_phaseone/
  28. 28. So what? • Lurking within any social network site profile is a host of clustered peers. Discovering these groups through community detection is an effective way to bring coherence to a profile, and help it scale. • Consider: planning a party, recommending a concert, sending out important news.
  29. 29. Nearness is now a social property as much as a spatial one. This is not the same thing as collaborative filtering. Networks do not signify similarity, they signify community. These are the people that do things together, disclose information to each other.
  30. 30. Looking forward Particular relationships create networks. Norms of access create overload. Thinking local is one solution, but it is partial. We need to create contexts, so users don’t have to.
  31. 31. Thank You Bernie Hogan Research Fellow, OII ;) @blurky bernie.hogan@oii.ox.ac.uk
