This document summarizes Professor Axel Bruns' research on analyzing large-scale social media data from Twitter in Australia. The research maps over 2.8 million identified Australian Twitter accounts and their follower/followee networks. It analyzes user engagement patterns around hashtags, news sites, and events. Tracking Australian Twitter activity over time provides a comprehensive dataset for understanding public discussions and responses to events in Australia.

4. RESEARCH PROJECT
• ARC Future Fellowship:
– Four-year project
– Axel Bruns (FF), Brenda Moon (Postdoc), Felix Münch (PhD1, 2014-2017);
PhD2 (2016-2018)
At the intersection of mainstream, niche, and social media, the
processes by which public opinion forms and public debate unfolds
are increasingly complex, and poorly understood. This project draws
on large datasets and innovative methods to develop a new model of
the Australian online public sphere.
• Also supported by ARC LIEF project:
– Two-year project (2014/15; QUT, Curtin, Deakin, Swinburne) to develop
comprehensive infrastructure for large-scale social media data analytics

5. BIG SOCIAL DATA
(http://siliconangle.com/blog/2011/08/09/twitter-unravel-the-mysteries-of-big-data/)

6. TWITTER: STATE OF THE FIELD
• Twitter research to date:
– Abundance of hashtag studies: volumetrics, keywords, networks, …
– Some studies profiling samples of the total userbase (e.g. celebrities, politicians)
– Some comprehensive (?) tracking of activities around key events and topics
– Some egocentric follower network maps, largely small-scale
– Almost absent: comprehensive follower network maps, longitudinal userbase development
trajectories, user career patterns from sign-up to listener/celebrity/…
• The political economy of Twitter research:
– Twitter API data access is shaped to privilege certain approaches
– Research funding is easier to obtain for specific, limited purposes
– Longitudinal, ‘big’ data access requires ongoing, substantial funding and infrastructure
– Exploratory, data-driven research is difficult to sell to most funding bodies
– Also related to divergent resources available to different scholarly disciplines
 Most ‘hard data’ Twitter research conducted by Twitter, Inc. and commercial research institutes

8. BEYOND HASHTAGS
• Key needs in Twitter research:
– Understand how hashtags are situated in a wider communicative ecology on Twitter
– Document the day-to-day uses of Twitter, beyond and outside hashtags
– Trace the dynamics of Twitter as a platform for everyday quasi-private, interpersonal,
and/or public communication
– Track the impact of social and technological changes on these uses
• ad hoc publics,
often rapidly forming
and dissolving
macro:
#hashtags
• personal publics,
accumulating slowly
and relatively stable
meso:
follower networks
• interpersonal
communication,
ephemeral
micro:
@replies
(Bruns & Moe, 2013)

9. THE AUSTRALIAN TWITTERSPHERE
• Twitter in Australia:
– Strong take-up since 2009
– Centred around 25-55 age range, urban, educated, affluent users (but gradually broadening)
– Significant role in crisis communication, political communication, audience engagement, …
• Mapping the Twittersphere:
– Long-term project to identify all Australian Twitter accounts
– First iteration: snowball crawl of follower/followee networks
• Starting with key hashtag populations (#auspol, #spill, …)
• Map of ~1m accounts in early 2012
– Second iteration: full crawl of global Twitter ID numberspace through to Sep. 2013
(~870m accounts)
• Filtering by description, location, timezone fields
• Focus on identifiably Australian cities, states, timezones and other markers
• 2.8 million Australian accounts identified (by Sep. 2013)
• Retrieval of their follower/followee lists
• Best guess of account location based on timezone, location and description settings

11. MONTHLY GROWTH (AUSTRALIA)

12. MAPPING THE AUSTRALIAN USERBASE
• Mapping the Twittersphere:
– Filtered to include only accounts with (followers + followees) >= 1000
• 140k accounts, 22.8m follower/followee connections within this group
– Mapped using Gephi Force Atlas 2 algorithm (LinLog mode, scaling 0.0001, gravity 0.5)
– Qualitative interpretation of network clusters based on high-degree nodes in each cluster
– Exploration of key profile statistics (join date, number of tweets, tweeting rate)
• Activity Patterns:
– Data gathered on selected tweeting activities (hashtag participation, link sharing, …)
– Data filtered for participating accounts included in the 140k most connected users
– Data superimposed on underlying network map
• Applications:
– Combined analysis of network structures and tweeting activities
– Evaluation of user engagement across topics
– Comparative benchmarking across activities
