Ongoing Research on Politics & Twitter - CSS Colloquium

  1. 1. Politics & Twitter Talha Oz Center for Social Complexity George Mason University 02/20/2015 Source code & datasets are on GitHub
  2. 2. Political leaning of US news media sources • 24 news media • Jaccard for closeness • Global network positioning (GNP) to scale media bias measure, named ADA (Americans for Democratic Action) score
  3. 3. Similarly, @GM and @Avis are very close in the low-dimensional embedding. Again, this makes sense as “[s]ince the late 1970s, Avis has featured mainly General Motors (GM) vehicles”… …are still useful for online advertising… “lifestyle politics” can be studied by using co-following information…
  4. 4. Polarity of Turkish News Media • Meet/min • Weighted Graph • Community Detection – A modularity based method (Gephi)
  5. 5. Visualizations Beyond 1-D • Media similarity matrix with D3 – Similarity view • Selective exposure or blinkers ? – Cluster view (weak validation) • List of newspapers in Turkey (Wiki) • Dogan Media Group (Wiki) • Former Milli Gorus (Facebook post) • Gulen Movement (Today’s Zaman) • Socialism, Leftism (Radikal) • Nationalism, Kemalism (Tweet)
  6. 6. Turkish Media in 2D • Multidimensional Scaling (sklearn.manifold.MDS) – Similarity to distance matrix • Turkish media networks (Force Atlas Layout 2, Gephi) – Force Directed Drawing • Colors are for 11 clusters
  7. 7. Political Groups & News Media • Media Preference of Five Groups in Turkey • Group Descriptiveness of the Turkish Media – Bar length = (similarity of party x to media y) / (sum of all party sims to y) AKP
  8. 8. DD-CSS • Data-driven Computational Social Science – is an effort to build new tools to help collect and analyze social media data – I did not know about any data collection tools (now there is a list) – tools for network analysis Gephi, Pajek and UCINET – powered by Flask, a highly modular microframework for Python
  9. 9. DD-CSS Demo • http://dd-css.com/ • US-senate.csv
  10. 10. Commentary Tweets of the Elites • Curated tweets of opinion-shapers and newsmakers • By nediyor.com and theplazz.com news sites • Commentaries on important events (news that have made to headlines) between Jan 2013 and Jan 2015. – “our visitors are plugged into the national conversation through up-to-date commentary that is insightful, humorous, combative, thought-provoking and just plain newsworthy.”
  11. 11. Early findings… • http://talhaoz.com/news/ • https://plot.ly/~toz/199/turkish-newsmaker-commentators-by-profession-curated-by-nediyorcom/
  12. 12. Politics… • Newsworthy Tweet Counts of TR Parties plotly • http://talhaoz.com/news/US-Congress-Commentators.html – Politician counts curated – Activity of these politicians – Which events/news got the most attention – When comment-count differences maximized
  13. 13. Wrap Up • Detecting Media Conglomerate and Groups using Twitter • Political Group Descriptiveness of the News Media • DD-CSS: A social media data collection platform • Commentary Tweets of the Elites and Congresspeople • Turkish Election Maps and Scenario Analysis
