  3. 3. TWITTER IN GERMANY (AND BEYOND) • Identifying the German-language Twittersphere: – Crawl of entire global Twittersphere, as at September 2013 (~870 million accounts) – Filtering for German(-language) users: • Location / Description fields of account profiles: – City and state names in Germany, Austria, Switzerland (false positives excluded) – Generic country terms – Uniquely German words (“und”, “ich”, “nicht”, …) • German set as user interface language at Twitter.com – Repeat crawl planned later in 2015 – Collaboration with the Centre for Digital Humanities at Georg-August-Universität Göttingen • Results: – ~9.2 million unique accounts identified – 2.481 billion statuses posted (until Sep. 2013)
