SUMMARY:Lunch Seminar: Maryam Saeedi - Carnegie Mellon
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:<p>(Dis)Information Wars</p><p>Abstract:</p><p style="text-align: justify;"
 >The growth of big data and big data technologies has greatly expanded info
 rmation availability across the globe. This has in turn led to the widespre
 ad use of social media platforms and the emergence of these platforms as pr
 ominent vehicles for displaying dissidence during episodes of political unr
 est. A new approach taken by oppressive governments to counter this trend i
 s to spread false information on the platform and engage in a disinformatio
 n war. We use data from Farsi-Twitter during the recent wave of protests in
  Iran to understand the extent and mechanism of disinformation wars. We ide
 ntify accounts that engage in spreading disinformation and use the characte
 ristics that predict such engagement to assign a “disinformation score” to 
 all Farsi-Twitter accounts. This score can guide safe users and inform poli
 cies to contain the spread of disinformation on social media. We run a numb
 er of counterfactual studies to test the effectiveness of various policy in
 terventions.</p>
