• Nodes in a network, entities in a collection
• Sharing certain measurable properties
(attributes, connections)
• Artificially grouped based on (superficial?)
similarities
Clusters How and Where to Find Them
• Modularity detection in networks
• Clustering by attributes for other datasets
• Different levels of sensitivity might produce
very different results – no one true answer
• Potential hierarchies: clusters, subclusters,
subsubclusters, …
CRICOS No.00213J

• Stable relationships and distinct roles
Groups How and Where to Find Them
• Strong, repeated, stable interconnections /
interactions
• Shared language, identity markers, media
objects
• Similar activity patterns
CRICOS No.00213J
• Larger, key members known to each other
• Shared but contestable interests, values,

• More complex structure involving centre

• Shared but contestable interests, values,
and aims
• More complex structure involving centre
and periphery, leaders and followers
Communities How and Where to Find Them
• Repeated, stable interconnections /
interactions
• Emergence of influential lead participants
• Centre / periphery distinctions (e.g. 1/9/90,
Pareto: creators, contributors, lurkers)
• More interactions within community than
outside it (e.g. E-I Index)
• Broadly shared language, identity markers,
media objects
CRICOS No.00213J
• Much larger and much less knowable
• Transient and temporarily gathered in one

Crowd How and Where to Find Them
• Large to very large number of participants
• Strong activity for limited period of time, or
around defined issues
• Similar activity patterns, but limited
interaction between participants
• Shared language, identity markers, media
objects relating to specific driving issue
CRICOS No.00213J
• Centred around shared interest, issue, text
• Capable of forming and dissolving rapidly

• Aware of each other and able to
communicate publicly
• May develop shared values through their

• Capable of organising in support of a

Public How and Where to Find Them
• Large to very large number of participants
• Strong activity for limited period of time, or
around defined issues
• Similar activity patterns, and greater levels
of interaction between participants
• Shared language, identity markers, media
objects relating to specific driving issue
• Centring around key values can produce
longer-term structures and leadership
CRICOS No.00213J
• Centred around a shared (media) text
• Large but dispersed and usually unknown
to each other
• Unlikely to share values beyond central
common interest
• Incapable of acting together

CRICOS No.00213J
• Centred around a shared (media) text
• Large but dispersed and usually unknown
to each other
• Unlikely to share values beyond central
common interest
• Incapable of acting together
Audience How and Where to Find Them
• Unified by central text (live performance,
media object, event / issue hashtag, …)
• Participant numbers from niche to very large
• Observing rather than actively contributing
• Therefore invisible to and unaware of each
other
• Often imagined and assumed rather than
tangibly traceable
CRICOS No.00213J
And #Hashtags?
• Very common question in social media research:
• Audiences: if users are simply following the hashtag (#AUSvNZL)
• Crowds: if users are posting into but not following the hashtag (#auspol, for most people)
• Publics: if hashtags are used to coordinate public action (#metoo, #blacklivesmatter)
• Communities: if there is sustained engagement by regular participants (#auspol, for some)
• Groups: if there is a strong sense of shared identity between regulars (#agchatoz)
• Clusters: sure, as long as there is any activity at all
Not every hashtag is a community!
CRICOS No.00213J
And the Public Sphere?
CRICOS No.00213J
• “Mediated political communication”
• “Carried on by an elite”
• “On a virtual stage of mediated
communication”
(Habermas, 2006)

Publics,

Everyday
communication
CRICOS No.00213J
• Publics, Crowds, …
• Triggered by issues and events
• Fast-moving and short-lived
• Limited in focus and scope
• Public Spherules (incl. Groups, Communities)
• Defined by topics and themes
• More persistent and stable
• Broader scope but unified by common theme
(cf. Cunningham, “Popular Media as Public
‘Sphericules’ for Diasporic Communities”)
• Public Spheres?
• Domain-, identity-, platform-specific
• E.g. political, Indigenous, Twittersphere
• Persistent and highly visible
• Encompassing relevant publics and spherules
• ‘The’ Public Sphere?
• Traditionally, an arena for public debate amongst
elites in front of mass media audiences
• Now, the sum total of smaller publics, spherules,
and spheres?
