\nBernardo Huberman (HP) \u00c2\u00a0- Getting Attention1. In last decade, web moved from download to 2-way2, Everyone has a megaphone\t(the interweb is one big ethernet?:-)3. attention is therefore the scarce resource\tattention is a coordination\/rendezvous\/synch mechanism\tanything except attention can be commodotized\tdefn: attention in social terms (pagerank)4. Looking at this, we can build predictors\tand make money...5. Looked at Attention Seeking behaviours...\tdoesn't matter if its your friends who applaud
\nSanjeev Goyal - Contagion1. random v. smart attacks2. central v. distributed Net designer3. Design for resilience
\nQ (BH). can we filter spam on this basis\/cost?(c.f. Ross work - can't afford email anymore)\t------>
\nMaxi San Miguel \u00c2\u00a0(IFISC) What can we learn from simple social behaviour models
\nisolate interaction mechanisms and find collective effectsfind causal relationsips...
\none example: random imitation\trole of topology\tco-evolution\theterogeneity in timing of interactionsExample: voters - imitation dynamics\tabosrbing states (all coloured red\/green)\twhen&how do we get (what about metastable case\/oscillitory?)\tresults anayltical for regular nets show ordering...\tin complex nets (small world or BA etc) , can get \u00c2\u00a0non stable soln\t\tlong range ties don't ctually help reachign agreement, counter-intuitive\t\tcritical beaviour determined by mean node degree (c.f. haggle)dynamics of net (formation) & on the net (usage)\tbut can we have co-evolution of agents and netrightwing view is net determis individual chocesleftwin view is individals constrined by social net :-)\tco-evol has model of agent\/link changing\/selected with distribution\tre-wiring rate v. use rate has critical phase changesheterogeneity in timing of individual activitie...\tempirically, we don't work at constant rate...\tso include a notion of node-specific internal \u00c2\u00a0time..
\nKeys\tdimenaionality\tcoevolution\ttimingTakehomes\tstrong messages dont homogenize, but polarize\tsocial interaction can lead to consenss different from external message
\n------>
\nMartin Everett - Manchester - dual project for 2 mode data
\n2 distinct groups - interaction netween group, not users in each group\te.g. wikipedia & postersexample dataset\twomen & southern events...problem - projection can lose data\tcan we do directly? not necessarily...turns out (math says) there isn't much loss...\tcan do SVD\u00c2\u00a0\tmakes it easy to find core\/key eents,\u00c2\u00a0\t\tand key people in women\/southern fried chicken e.g.\tand various other clustering things...can use this to find centrality-\u00c2\u00a0discover key agents in women getting other women to events
\ntakehome -\u00c2\u00a0\tignore incorrect folkore about losing info in this approach...<\/p>\n
------->
\nRoss Anderson (CL) Temporal Node Centrality - work with hyoungschick kim<\/p>\n
<\/p>\n
starting with attacks\/defense on scale free net hubs etc....<\/p>\n
<\/p>\n
results in papers by Hyoungschick et a...<\/p>\n
<\/p>\n
------><\/p>\n
Cecilia Mascolo (CL) Geo-spatial<\/p>\n
Case study - add in geo-info (like foursquare) - with geo-tagging of postsm can see where messages\/interactions occur.<\/p>\n
<\/p>\n
questions of interest -<\/p>\n
1. relation twixt geo-distance and social distance - for example<\/p>\n
2. distance and degree<\/p>\n
Applications - can we exploit geo-spatial info\u00c2\u00a0to build better social apps and systems?<\/p>\n
1. link prediction....<\/p>\n
2. movement model\/prediction<\/p>\n
Q&A for morning session chaired by Y.T. (for readers of snow crash:)<\/p>\n
