It's a Man's Wikipedia?
Who are your life heroes?
How did you learn about them?
The heroes we share are the heroes we have
Our Study
• Compare for men and women:– Coverage– Lexical Presentation– Structural Position– Visibility
Claudia Wagner, David Garcia, Mohsen Jadidi and Markus Strohmaier, It's a Man's Wikipedia? Assessing Gender Inequality in an Online Encyclopedia, The International AAAI Conference on Web and Social Media (ICWSM2015)
Coverage
Coverage in 2011
• Britannica versus Wikipedia Coverage– Reference Lists: e.g. The Atlantic’s 100 most
influential figures in American history–Wikipedia misses 13% of women and 5% of
men– Britannica misses 49% of women and 33% of
men–Wikipedia’s coverage is more exhaustive–Women have a 2.6 (13/5) greater odds of
omission in Wikipedia and a 1.48 (49/33) greater odds of omission in Britannica Reagle, Joseph; Rhue, Lauren (2011). "Gender Bias in Wikipedia and Britannica". International Journal of Communication (Joseph Reagle & Lauren Rhue) 5: 1138–1158.
Our Study: Data
• 11% women in Freebase• 3% women in HA (people who made
contributions to arts and science prior than 1950)
• 13% women in pantheon

Importance
So what?!?!
Algorithms often use structural properties to determine importance (e.g. Page Rank)– Researchers need to understand
social consequences of algorithms– 28. Feb 2015: “Google wants to
rank websites based on facts not links”, NewScientist

“Biographies of women on Wikipedia disproportionately focus on marriage and divorce compared to those of men.”
David Bamman, Noel Smith. "Unsupervised Discovery of Biographical Structure from Text", Transactions of the Association for Computational Linguistics, 2, 2014 (pp. 363–376), p. 369:
Summary
• Good News:– Visibility and Coverage of women looks
good
• Bad News:– Structural Inequality what are the
consequences?– How women are portrayed needs to be
improvedhttp://en.m.wikipedia.org/wiki/User:GGTF/Writing_about_women

Future Questions…
• What causes the bias?–Wikipedia bias versus general media
bias?–Male versus female editors?
• Bias over time– Does the community improve?
