SUMMARY:Lunch Seminar: Maryam Saeedi - Carnegie Mellon University
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:\n\n(Dis)Information Wars\n\n\nAbstract:\nThe growth of big data and big da
 ta technologies has greatly expanded information availability across the gl
 obe. This has in turn led to the widespread use of social media platforms a
 nd the emergence of these platforms as prominent vehicles for displaying di
 ssidence during episodes of political unrest. A new approach taken by oppre
 ssive governments to counter this trend is to spread false information on t
 he platform and engage in a disinformation war. We use data from Farsi-Twit
 ter during the recent wave of protests in Iran to understand the extent and
  mechanism of disinformation wars. We identify accounts that engage in spre
 ading disinformation and use the characteristics that predict such engageme
 nt to assign a “disinformation score” to all Farsi-Twitter accounts. This s
 core can guide safe users and inform policies to contain the spread of disi
 nformation on social media. We run a number of counterfactual studies to te
 st the effectiveness of various policy interventions.\n
