CMU SCS
Interactions
(1) Mobility -> social networks– More info/context (who is where, and when)– Easier to interact with friends

(2) Social networks -> cloud
Properties of social networks have high impact on algo design– ‘six degrees’– Power-law degree distributions– ‘No good cuts’

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)

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.)

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