2. TRENDING TOPICS ON TWITTER
• Twitter as “ambient news” (Hermida, Burns):
– Often rapid emergence and dissemination of new information
– Formation of ad hoc publics around new events, themes, topics (Bruns & Burgess)
– Emerging themes identified as “trending topics” by Twitter, often associated with hashtags
– Clearly visible as a result of trending – but what happens in the early stages?
– Difficult to retrace trends to their point of origin, due to API access limitations
– Need to understand / evaluate trending against context of:
• existing network structures / typical activity patterns (also largely unknown)
• coverage across wider media ecology
• How to move forward?
– Comprehensive investigation of background networks / activity patterns
– Speculative data gathering in advance of possible trending topics
3. BACKGROUND
• Twitter in Australia:
– Comparatively strong take-up: ~2.8m accounts (population 23m)
– Demographics: 25-55-year-olds, affluent, educated, urban
– Historically strong focus on politics, e.g. #auspol, #ausvotes
• Politics in Australia:
– Westminster system: Australian Labor Party vs. Liberal / National Coalition
– 2010-13: ALP minority government, supported by 3 Independents + 1 Green
– Prime Minister Julia Gillard (ALP), Oposition Leader Tony Abbott (Lib)
– Highly controversial, aggressive atmosphere in parliament
– Deeply personal attacks on Gillard (as unmarried, atheist woman) in parliament
and media
4. MISOGYNY DEBATE
• 9. Oct. 2012: Gillard strongly criticises Abbott in ad hoc 15-minute speech
http://www.abc.net.au/news/2012-10-09/julia-gillard-attacks-abbott-of-hypocrisy/4303634
• Trending topic on Twitter, 2.5m views on YouTube (by mid-2014)
6. RESEARCH DESIGN
• Australian Twitter News Index:
– Continuous ATNIX data gathering since mid-2012
– All tweets containing links to leading 30+ Australian news sites
– Focus here on Australian Broadcasting Corporation post of the
15-minute video
– I.e.: YouTube and other distribution paths not included
• Analysis:
– Identification and temporal / network analysis of tweets identified in
ATNIX dataset
– Two phases: 0-5 hours / 5-75 hours after first tweet
7. THE FIRST FIVE HOURS (0-18,000s)
• Network visualisation:
– Every node represents one account
• Node size: number of retweets received across entire 75h
timeframe
• Node colour: cluster membership (according to Gephi algorithm)
– Each edge represents one or more retweets
– Each step represents 15 minutes
– Video: http://youtu.be/4V81s5sAiqM
8. ANALYSIS OF MAIN ACTORS (0-5h)
• Geography:
– 29 Australians, 1 New Zealander, 1
British
• Background:
– 10 journalists
– 8 feminists
– 5 private accounts
– 4 activists
– 3 comedians
– 1 cartoonist
• Gradual transition from journalists to
feminists
• Final addition: commentator for
Guardian (UK)
9. NEXT 70 HOURS (18,000-270,000s)
• Network visualisation:
– As previous
– Each step represents one hour
– Video: http://youtu.be/-IhAdHOIa08
11. DYNAMICS OF THE RETWEET CHAIN
• From parliamentary procedure to media event:
– First attention from journalists and “political junkies”
– Commentators and comedians broaden the base
– Feminists become active
• From Australia to the world:
– First tweets from UK delayed by timezone differences
– Understandable interest:
• Historical connections, Australian expat community in UK
• Similar political systems, interlinkages between media organisations
• Guardian Australia as Australian offshoot of Guardian (UK)

27. RESULTS
• Dissemination dynamics:
– Long tail early on, fat head towards the end:
• starts with many individual shares by a diverse range of participants,
• ends mainly with retweets of best-known / most influential accounts
• Event dynamics:
– From breaking news to longer-term media / political issue
– From political spectacle to feminist rallying cry
• Network dynamics:
– Flat at first, then increasingly structured
– Single acocunts (e.g. @dawnhfoster) as bridging points to new networks
– Influencers most persistently retweeted
28. FUTURE AIMS
• Further research:
– Continued improvement of analytical methods
• Other approaches to analysing / visualising retweet chains?
– Repeat for other cases
• How to gather data (beyond ATNIX)?
– Comparisons across other themes, and national contexts
• Different forms of breaking news, different Twitterspheres
– Importance of background data
• E.g. follower networks, Twitter careers of participating accounts
– Impact of coverage in other media?
• Fewer retweets for themes already prominent in other media?
