Twitter Campaigning Strategies in the 2019 Australian Federal Election

Politics in Australia
● It’s … complicated:

Politics in Australia
● Persistent instability:
● Six changes of Prime Minister since 2007
● Four of these through intra-party leadership challenges (‘spills’)
● Only two as a result of elections

Data and Methods
● Data:
● All tweets by and directed at (@mentions + retweets) all known House and
Senate candidate accounts on Twitter
● 22 April (close of nominations) to 17 May 2019 (day before election day)
● Same approach as 2013 (Bruns, 2017) and 2016 (Bruns & Moon, 2018)
● Analysis:
● Overall activity patterns (Axel)
● Themes of discussion (Dan)
● Presence of social bots (Tim)
12. @qutdmrc
Bots (or Highly Automated Accounts)
● Analysis of bot-like, highly automated accounts
● Election interference and political manipulation
● 2016 U.S. Election (Bessi & Ferrara, 2016, Rizoiu et al, 2018)
● Spreading fake news (Shao et al, 2018)
● 2017 French Presidential Election (Ferrara, 2017)
● Misdirecting online discussion of the Syrian civil war (Abokhodair et al, 2015)
● … and more
● Botometer classifier
● Bot score
● CAP score
● Caveats…
13. @qutdmrc
Bot Presence During the Election
● 7,764 accounts (9%) with bot
score greater than 0.6
● But only 1,359 accounts (1.5%)
with CAP score > 0.8
● Volumes alone provide mixed
evidence about bot activity
● We define two populations of user
accounts (Rizoiu et al (2018):
● ‘Bot’ = botometer score > 0.6
● ‘Human’ = botometer score < 0.2
Bot-like range
16. @qutdmrc
What Do ‘Bots’ Talk About?
● Logistic regression - examine correlation between themes/topics and
CAP score (converted to binary variable)
● IVs: Topic probability vectors (from Dan’s analysis)
● DV: CAP score binary (human < 0.2; bot > 0.8)
Category Topic/theme Coefficient

● Findings
● Bots much less likely to be
critical of the government
(LIB)
● Bots much less likely to
discuss climate change
● Bots much more likely to be
supportive of QLD coal
companies
17. @qutdmrc
Some Preliminary Conclusions
● Dynamics:
● Many more retweets for opposition parties (but not necessarily the leaders)
● Clear focus on Liberal Party within the conservative Coalition
● Clear distinctions in media content being shared
● United Australia Party ran separate interference campaign
● Topics:
● Diversity of online discourses – there is no single ‘big’ election-defining issue
● Bots:
● Bots distribution by topics suggests that bots are preferentially targeting specific
topics
● Bots appear to be partisan
● Surge of bot accounts created before the election?
● Bots were quite active but it is unclear how much impact they had
