2. Why Twitter?
o Researching Twitter:
o Significant world-wide social network
o ~200 million users (but how many active?)
o Varied range of uses: from phatic communication to emergency
coordination
o Healthy third-party ecosystem (for now)
o Strong history of user innovation:
@replies, #hashtags
o Flat and open network structure:
non-reciprocal following, public profiles by default
o Good API for gathering data for research

3. New Media and Public Communication:
Mapping Australian User-Created Content
in Online Social Networks
o Australian Research Council (ARC) Discovery Project (2010-13) – $410,000
o QUT (Brisbane), Sociomantic Labs (Berlin)
o First comprehensive study of Australian social media use
o Computer-assisted cultural analysis: tracking, mapping, analysing blogs, Twitter, Flickr,
YouTube as ‘networked publics’
o Addressing the problem of scale (‘Big Data’) and disciplinary change in media, cultural and
communication studies – natively digital methods
o Studying society with the Internet (Richard Rogers)

4. #hashtag Publics
o #hashtags
o ‘#’ + keyword makes tweets easily discoverable and marks themes
o E.g. #ausvotes, #qldfloods, #londonriots, #royalwedding, #euro2012, …
o Publics
o Attend to matters of shared concern with some level of co-awareness
o Varied in intensity and temporality
o Emergent, constituted via discourse & affect
o #hashtag publics
o Not all hashtags constitute publics; Twitter doesn’t ‘contain’ publics
o What are the patterns in the dynamics of different hashtag-based publics?
o What might account for these differences?

7. But Why?
o Possible research questions:
o Ad hoc events and publics:
o How do online publics form and dissolve? How do they
interact, what structures do they form?
o Where do they draw information from? What do they share?
o Do they simply consist of the usual suspects? How insular
and disconnected are online publics?
o Hashtags in context:
o How do different hashtag events compare? Are there
common types of hashtags/publics?
o How ‘big’ are they? What topics attract attention on
Twitter?
o What community (?) structures emerge?

8. Hashtag Publics, Hashtag Metrics
o How big is the central core of users?
o Long tail distribution: most active users responsible for
the majority of content
o 90/9/1 rule: how much does the top 1% of users
contribute?
o #royalwedding: ~10% of all tweets
o #qldfloods: ~17% of all tweets
o #auspol: ~65% of all tweets
o What do they do: inform, share, chat?
o How many links do they share?
o How much retweeting do they do (edited/unedited)?
o How many @replies do they send / receive?
o … etc.

9. Towards Comparative Metrics

10. Towards a Typology of Twitter Uses
o How are hashtags used (during acute events)?
o Gatewatching:
o Finding and sharing information about breaking news (before
the mainstream media do?)
o Ad hoc publics: many URLs, many retweets (even unedited)
o Audiencing:
o Shared experience of major (foreseen) events
o Imagined community of fellow participants: few URLs, limited
retweeting
o What other uses are there?
o Continuing discussions (#auspol, #bundesliga, …)
o Memes (#ghettohurricanenames, …)
o Emotive hashtags (#fail, #win, #headdesk, …)
o What about keywords?

11. Beyond Hashtags
o Publics on Twitter:
o Micro: @reply and retweet conversations
o Meso: hashtag ‘communities’
o Macro: follower/followee networks
 Multiple overlapping publics / networks
o What drives their formation and dissipation?
o How do they interact and interweave?
o How are they interleaved with the wider
media ecology?
o Twitter doesn’t contain publics: publics transcend Twitter

14. Understanding Australian Twitter Use
o What is the Australian Twitter userbase?
o Large-scale snowballing project
o Starting from selected hashtag communities
(e.g. #ausvotes, #qldfloods, #masterchef)
o Identifying participating users, testing for ‘Australianness’:
o Timezone setting, location information, profile information
o Retrieving follower/followee information for each account
(very slow)
o Progress update:
o ~950,000 Australian users identified so far, ~21m connections
 ~2 million Australian users in total?

15. The Australian Twittersphere?
Follower/followee network:
~150,000 Australian Twitter users
(of ~550,000 known accounts by mid-2011)
colour = outdegree, size = indegree

16. The Australian Twittersphere?
Follower/followee network:
~120,000 Australian Twitter users
(of ~950,000 known accounts by early 2012)
colour = outdegree, size = indegree

18. #Hashtag Participation
Follower/followee network:
~120,000 Australian Twitter users
(of ~950,000 known accounts by early 2012)
size = indegree

19. #auspol
Follower/followee network:
~120,000 Australian Twitter users
(of ~950,000 known accounts by early 2012)
colour = #auspol tweets, size = indegree

20. #ausvotes
Follower/followee network:
~120,000 Australian Twitter users
(of ~950,000 known accounts by early 2012)
colour = #ausvotes tweets, size = indegree

21. #qldfloods
Follower/followee network:
~120,000 Australian Twitter users
(of ~950,000 known accounts by early 2012)
colour = #qldfloods tweets, size = indegree

22. #masterchef
Follower/followee network:

25. Understanding Twitter Publics
o #hashtags:
o Useful coordinating mechanism for core discussion
o Relatively easy to capture and analyse
o Fails to capture non-hashtagged tweets about the topic
o Good case studies, but very little comparative work to date
o National / global Twittersphere maps
o Crucial contextual baseline for #hashtag case studies
o Slow and laborious data gathering process, never complete
o Very long-term perspective, beyond most funded projects
o Indispensable for study of Twitter as a public space

26. ‘Big Data’ and the Digital Humanities
o Emerging needs in Twitter research:
o Unified, compatible methods and metrics for Twitter analysis
 Tools and approaches shared at http://mappingonlinepublics.net/
o Powerful infrastructure for long-term, high-volume tracking of
Australian public communication on Twitter
 Data access requires substantial funding stream
o Facilities for long-term data storage and preservation
 Key roles for National Library, National Archives
o Integration with related datasets (e.g. MSM content)
 Need to address data interoperability questions
o Twitter as a test case for digital humanities research
o Widespread, open, public platform for everyday communication
o Tool for observing society at scale through Internet research
