  1. Mobility and Social Networks in the cloud Christos Faloutsos CMU

  2. Interactions (1) More data Social net’s mobility (3) tools cloud More data (2) Insights; Research problems C. Faloutsos (CMU)

  3. Interactions (1) Mobility -> social networks • More info/context (who is where, and when) • Easier to interact with friends C. Faloutsos (CMU)

  4. Interactions (1) More data Social net’s mobility (3) tools cloud More data (2) Insights; Research problems C. Faloutsos (CMU)

  5. Interactions (2) Social networks -> cloud Properties of social networks have high impact on algo design • ‘six degrees’ • Power-law degree distributions • ‘No good cuts’ C. Faloutsos (CMU)

  6. Interactions (1) More data Social net’s mobility (3) tools cloud More data (2) Insights; Research problems C. Faloutsos (CMU)

  7. Interactions (3) Social networks <- cloud Conversely, mass of data needs cloud / map-reduce etc techniques to be • Stored (sharded / replicated etc) • Searched (show me quickly my friends) • Analyzed (link prediction) • Monetized (which ad to show to whom) C. Faloutsos (CMU)

  8. Research challenges for mining • Understand how networks form; how humans interact • -> sociology • -> marketing • -> … • How rumors/ideas/memes spread • Mobility patterns of humans (bio virus prop.) C. Faloutsos (CMU)

  9. Research challenges for mining • Spot anomalies, i.e. • account hijacking; • spammers; • behavior change (disgruntled employees) C. Faloutsos (CMU)
