  This paper investigates bias in coverage between Western and Arab media on
Twitter after the November 2015 Beirut and Paris terror attacks. Using two
Twitter datasets covering each attack, we investigate how Western and Arab
media differed in coverage bias, sympathy bias, and resulting information
propagation. We crowdsourced sympathy and sentiment labels for 2,390 tweets
across four languages (English, Arabic, French, German), built a regression
model to characterize sympathy, and thereafter trained a deep convolutional
neural network to predict sympathy. Key findings show: (a) both events were
disproportionately covered (b) Western media exhibited less sympathy, where
each media coverage was more sympathetic towards the country affected in their
respective region (c) Sympathy predictions supported ground truth analysis that
Western media was less sympathetic than Arab media (d) Sympathetic tweets do
not spread any further. We discuss our results in light of global news flow,
Twitter affordances, and public perception impact.
