PLANTIN 2012 "From one map to the other: what maps can tell us about graphs (and the other way around)"

  1. 1. Jean-Christophe Plantin Université de Technologie de Compiègne jean-christophe.plantin@utc.fr Cartonomics.org Nedimah Workshop, DH2012, July 21. 2012 From one map to the other: what maps can tell us about graphs (and the other way around)
  2. 2. // Maps and graphs The object of research   The method of research  Alternative radiation mapping mashup Controversy mapping (Venturini after March 11. 2011 in Japan 2010) (Latour 2010) Source: blog.Safecast.org // futureperfectpublishing.com/
  3. 3. // 5 challenges for maps and networkgraphs (+ solutions and makedo) #1-The steps of creation #2-Temporal development #3-Subjectivity and black-boxes #4-Beyond hyperlink map #5-Image status
  4. 4. // Tools Navicrawler (Jacomy, Ghitalla, 2007) (Plantin 2012): -”manual” exploration -nodes labeling Gephi (Bastian et al., 2009), (Jacomy -visualization -back to the exploration, etc. et al. 2011) http://webatlas.fr/wp/navicrawler/
  5. 5. // Result Gephi.org // cartonomics.org
  6. 6. Challenge #1. The steps of creation August 2012 September 2012 October 2012 -Dangers of “self-reference” & “iconization” of the map (Casti, 2005) -The graph is created constructed and chosen amongst many possibilities
  7. 7. Solutions #1. •  Showing the various steps of the process (easy in a dissertation, less in a scientific article) •  A dynamic version of the graph
  8. 8. Challenge #2. Temporal development Creating the corpus March 11. 2011 August 2011 December 2011 Now ”A website graph is outdated as soon as it is made” (Girard, 2012) ”Violence of mapping” (Farinelli 2009): freezing a dynamic process
  9. 9. Solutions #2. •  Clearly showing the temporal boundaries of the graph •  Automation of the crawling process (Sack, 2007)
  10. 10. Challenge #3. Subjectivity and black boxes Manual crawler (Navicrawler): risk of a taylor-made corpus Automatic crawler (Issuecrawler): risk of black-boxing (Rieder, Rhöle, 2012) Issuecrawler.net
  11. 11. Solutions #3. •  Reading the scientific articles (but sometimes not enough, eg. Brin, Page, 1998) •  Double-checking with people inside the graph •  Using only open-source tools? http://berlinergazette.de/symposium/learning-from-fukushima/
  12. 12. Challenge #4. Beyond hyperlink map -How to map non-hyperlink-related forms of online cooperation? -Web is plateform: non-crawlable networks -API research (Helmond 2012) Cosm.com
  13. 13. Solutions #4. •  Using various methods to ground the graph (Rogers, 2009): interviews, documenting the case, “participatory research”
  14. 14. Challenge #5. Status of the image -Beyond the assumption of objectivity (boyd, Crawford, 2011) -Graph is an exploratory tool, not an end in itself Fr.123.rf.com
