Analysing the Norwegian Twittersphere

  1. 1. Analysing the Norwegian Twittersphere Prof. Axel Bruns Digital Media Research Centre Queensland University of Technology Brisbane, Australia a.bruns@qut.edu.au | @snurb_dot_info
  2. 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. 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. 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
