2. 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
3. Mapping the Twittersphere
• 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)
– Third iteration: full crawl of global Twitter ID numberspace through to Dec. 2015 (~1.4b accounts)
– National filters:
• Filtering by description, location, timezone, language fields as appropriate
• Focus on identifiably local cities, states, timezones and other markers
• 2.8 million Australian accounts identified by Sep. 2013; 3.7 million by Dec. 2015
• Retrieval of their follower/followee lists
• Best guess of account location based on timezone, location and description settings

8. Mapping the Norwegian Twittersphere
• Selection criteria:
– Interface language = ‘no’ or ‘nb’, or
– User location mentions one of ~100 largest towns, ~90 municipalities, ~20 counties, or Norway/…, or
– User description mentions one of the locations, or other clearly Norwegian terms
– False positives removed (e.g. Bergen, NJ; Oslo, MN; “in den Bergen”; …)
– No matching on timezone: no specifically Norwegian timezone offered by Twitter
• Results:
– 967,560 Norwegian Twitter accounts as of Dec. 2015
– 38,807 protected accounts (~4%)
– 219 verified accounts
• Follower/followee network amongst Norwegian accounts:
– 716,076 accounts follow at least one other Norwegian account
– 32,534,829 follower/followee relationships between them
