What do you already know? Diffusion Happens Nets look niceSome are inﬂuencers Science has potential
Some Principles• Inﬂuence is not an obvious process.• Central people are not always the most popular people (but usually are)• Visualizations can be useful, but this takes work. Sciency is bull$#!†.
Some Limits• Estimating selection versus inﬂuence is extremely tough, even for the best.• Visualizing more than a couple thousand points? Congrats, its now art!• A link is not always a meaningful link• Data cleaning is the worst part. Seriously.
Network 1 Goals• Overview• What do clusters mean?• Who is considered more central?
Network 2 Goals• Is there cohesion among the group? • Many blobs or few? Core-periphery or multi-core.• Are certain people broadcasters?• How can we accentuate the story?• List people by number of tweets?
