Wikipedia mentioned in books in 1975

UPDATE: Dami, in a comment to this post, says “if a word appears in a newer edition of an older work (e.g. in the introduction section of cheap reprints of public domain books) Google will count it as an appearance at the time the original work was published.” I checked and this is true, thanks Dami!

I was playing with Google Books Ngram Viewer, which allows you to check how frequently certain phrases occurred in books published since 1950 up to 2008.
Curiously the following graph reports that some books (only 0.0000011% but greater than zero anyway!) were containing the work “wikipedia” (and “wiki”) already in 1950 and in 1975. Maybe there is a small bug even in mighty google services?

The following graph instead shows the increase (as expected) of mentions to “wikipedia” and “wiki” in books since 2003.

Percentage of men and women on different social networking sites (Facebook, Twitter, Linkedin, …)

Lots of debate arose around the fact almost 87% of Wikipedia editors are male. This is not necessarily true since the survey on which this “fact” is based has some biases (for example, people self-elected to answer).
However, a query run on the Wikipedia database showed that more than 83% self-identified as male.
While these numbers are not 100% representative of reality, it is probably true that most of editors are male. This is acknowledged also on a Wikipedia page about the systemic bias of Wikipedia (yes, I know this very page has been written by people whose bias we are trying to interpret but, going to the extremes, it’s turtles all the way down ;)

So the question could be: what is the ratio male/female on other social networking sites?

Just, for comparative reasons (and a bit for fun too), I compiled the following table based on the Social Network Analysis Report by Ignite Social Media. The table is sorted so that first lines are sites in which there are relatively more females than males. I’m not familiar with all the sites but it seems that sites more populated by women are the very social and playful (such as Haboo, Bebo, Myspace, Xanga, Facebook). On the other side of the spectrum there are sites populated most by males: sites showing what’s interesting right now thanks to social bookmarking such as Reddit, Digg, Identi.ca, and “professional” network sites such as Linkedin and Plaxo.
This table is not “scientific” in any way as well (for instance, percentages in the report are gathered from Google Ad Planner and Google Insights for Search).
Consider the following table just as more food for thought. Does it confirm your intuitions? Or should I say prejudices? ;)

Percentage of men and women on different Wikipedias

Few days ago there was an interesting article on NYTimes about the small percentage of women on Wikipedia.
Today on the gendergap mailing list at wikipedia there is a very interesting ongoing discussion. Some preliminary statistics from the discussion are:

Wikipedia in specific language Number of users who specified gender in preferences Percentage of users who specified gender in preferences How many men How many women Percentage of women
English
http://en.wikipedia.org
13959842 2.01% 233312 46973 16.76%
German
http://de.wikipedia.org
1167708 3.47% 35726 4800 11.84%
French
http://fr.wikipedia.org
998668 2.16% 18556 3054 14.13%
Serbian
http://sr.wikipedia.org
78180 2.66% 1666 414 19.90%
Russian
http://ru.wikipedia.org
620393 16.80% 80491 23750 22.78%
Polish
http://pl.wikipedia.org
414511 3.64% 12106 2999 19.85%
Dutch
http://nl.wikipedia.org
368815 2.92% 8977 1781 16.56%
Commons
http://commons.wikimedia.org
1464442 2.26% 27980 5070 15.34%

Interesting to note how on Russian Wikipedia, users tend to express their gender much more (16.80%!). Do you have ideas if (1) this is a cultural issue specific of Russians, (2) it depends on the practices of the specific Wikipedia in Russian or (3) it depends on the user interface, for example it might be that when you register you are redirect to an HTML page in which you can specify also your gender?
Also interesting is the fact that in this Wikipedia the percentage of women is the highest (22.78%). Probably the reason is that in a place in which gender is more represented, it is more normal for women to represent it as well. While where gender it is not represent, it is in general foolish for women to explicitly say “Hey, I’m female!” in order not to attract (additional) unwanted messages. Or put in other terms, OMG Girlz Don’t Exist on teh Intarweb!!!!1.

Professor: What is an encyclopedia? Student: Is it something like Wikipedia?

I was viewing the presentation by Steven Walling titled “Why Wikipedians are the Weirdest People on the Internet” (embedded below) and the second slide was a twit by alisonclement which says:

Yesterday I asked one of my students if she knew what an encyclopedia is,
and she said, Is it something like Wikipedia?

Amazing! Changing times indeed, I remember when I was a kid and one of the most valuable things in our house was a 20-something volumes encyclopedia, admiringly and respectfully placed at the center of our best cupboard … ;)

Larry Wall talk in Povo

On February 17, 2011 at 11:00, Larry Wall, creator of the Perl programming language, will give a talk in Povo (where I work), organized by CoSBI (The Microsoft Research – University of Trento Centre for Computational and Systems Biology).
The title is “That Goes Without Saying (or Does It)” and the abstract is:
Linguist Roman Jakobson famously said, ‘Languages differ essentially in what they must convey and not in what they may convey’ Contrary to the Whorf-Sapir hypothesis, your language of choice does not generally prevent you from thinking certain thoughts, but your language can certainly make it easier or harder to express those thoughts. Lately I’ve enjoyed playing with various Perl examples on rosettacode.org, and have noticed this principle in action. In this talk we’ll look at some of the ways a language can make your life more miserable than it needs to be.
The seminar is free of charge but for logistics reasons you need to confirm your attendance on CoSBI site.

Beautiful visualization of Wikipedia discussions on article deletions


straight AfD sample

s-shaped AfD sample


spiral-like AfD sample

At notabilia.net, Dario Taraborelli, Giovanni Luca Ciampaglia and Moritz Stefaner put together a neat visualization of the 100 longest Article for Deletion (AfD) discussions. Each time a user joins an AfD discussion and recommends to keep, merge, or redirect the article a green segment leaning towards the left is added. Each time a user recommends to delete the article a red segment leaning towards the right is added.

Influence of religion on altruism

Interesting blog post at “Experimental Turk, A blog on social science experiments on Amazon Mechanical Turk” by Gabriele Paolacci.

David Rand posted on Crowdflower about a great Amazon Mechanical Turk study he recently conducted along with John Horton on altruism (as measured by cooperative behavior on a Prisoner’s Dilemma), that also used religious priming. The authors found that (rearranged from the original post):

1. A majority of Turkers cooperate in a Prisoner’s Dilemma. Thus even in the entirely anonymous and profit-motivated online labor market of AMT, many people still choose to help each other.

2. Reading a religious passage about the important of charity makes religious Turkers more altruistic, but has no effect on Turkers who do not believe in god. This shows that Turkers respond in basically the same way as “normal” lab subjects, and is fairly intuitive. Those who believe in god are receptive to calls for generosity phrased in religious language, while non-believers aren’t.

Donna Haraway quotation

I will critically analyze, or “deconstruct”, only that which I love and only that in which I am deeply implicated

Donna Haraway (p. 151, Modest_Witness@Second_Millennium.FemaleMan©Meets_OncoMouse™: Feminism and Technoscience, New York: Routledge, 1997). Her web page HTML title says “Professor of Feminist Theory and Technoscience”. Wow!
