6. Media attention
• What (news) media pay attention to
• What news media report
The NYTimes reports news about Trump
The NYTimes pays attention to Trump

7. Media disregard
• What (news) media do not pay attention to
• What news media do not report
• Key challenges:
• How to distinguish what media did not know (and thus
could not report) a certain incident from what media
knew it but intentionally ignored it
• We get insights from how news industry works.
2
8. How can news media report events
happening at every corner of the world?
• Open offices in every country and hire journalists there
• Infeasible due to financial reasons
• Is there anyone who gathers news reports from the world
and sells “collected” news to news media again?
• This is exactly what news agencies do.
9. Reasonable assumptions to
capture media disregard
• If many news media outlets report a certain incident, that
piece of information was probably circulated by news
agencies as well.
• In this case, if there are news media outlets that do not
report that incident, we can reasonably assume that they
disregard it.
10. Multiplex network
• A multilayer network is a network made up by multiple
layers, each of which represents a given operation mode,
social circle, or temporal instance.
• In a multiplex network, each type of interaction between
the nodes is described by a single layer network.

13. Critical role of news media
• Even in the era of social media, our understanding of the
world is still dominantly shaped by news media [2]*.
*Reference number in the talk is the same as that in the paper.

15. Bias in foreign news coverage
• What we see, read, and hear about other countries is a
result of the gatekeeping by the journalists and of the
social, economic, and political relationships across
countries [3].
➡ Ideological discourses of hierarchy and inequality are
articulated throughout the mediated representation [11].
✓Understanding media attention is essential to detect bias
in news media and make news better.
16. Previous literature on
foreign news coverage
• Theory of news values
• Why some countries are more likely to be covered than
other countries (e.g., USA, UK, China, …)
• Systematic factors of international relationships
• Why one country covers a certain country more than
other countries (e.g., Japan frequently covers S. Korea)
18. Our approach
• We build a multiplex media attention and disregard
network (MADN) among countries and analyze its
structural characteristics.

19. Datasets we need
• Collect news from many countries in the world
• Handle English and non-English contents
• Do not filter specific types of news
20. Candidate: GDELT?
• The GDELT datasets http://www.gdeltproject.org/
• Supported by Google Jigsaw
• Monitors news media around the world in over 100
languages
• Actively studied in recent years [9]
• Not appropriate for our work
• Filters news according to predefined 300+ categories

23. Data collection
• Over 212 days, for each country, we collect
• Daily k topics mentioned more than other topics
• Daily k topics mentioned less than news media in other
countries mentioned (former definition is in the paper)
✴ 100 is the maximum number of topics that
Unfiltered.news offers for a given day.
24. How to choose k
• Considering human capacity for processing information*,
we choose k=10.

characterization in N
A
• Most of the country relationships (91.2%) are non-significant
for both-countries.
• Neighboring countries tend to show a strong dependency of
media attention.
• Hub countries get the significant media attention but do not
return back well.
• Former colonial ties show dependent relationships.
• While the US (1st) and Syria (2nd) have similar PageRank, they
receive significant media attention from 53 and 11 countries,
respectively.

76. Summary
• We investigate the structural characteristics of the
multiplex media attention and disregard network
(MADN) among 129 countries.
• Through multi-level analysis from the node level to the
network level, we found the skewed, hierarchical, and
asymmetric structure of the MADN.
• Media attention and disregard have different structures.
• We observe the “global village” trend in media attention,
but, at the same time, unique attention blocks remain.
77. Future work
• “Media attention” is somewhat led by media, editors, and
journalists (professional organization).
• We would like to compare this with the worldview of
typical users collected from social media.
• Also, we plan to compare media attention network to
country networks based on other data sources (migration,
flight, trade).
