Data Science of the Facebook World

Stephen Wolfram Blog
April 24, 2013

More than a million people have now used our
Wolfram|Alpha Personal Analytics for Facebook. And as
part of our latest update, in addition to collecting some
anonymized statistics, we launched a Data Donor program
that allows people to contribute detailed data to us for
research purposes.

A few weeks ago we decided to start analyzing all this
data. And I have to say that if nothing else it’s been a
terrific example of the power of Mathematica and the
Wolfram Language for doing data science. (It’ll also be
good fodder for the Data Science course I’m starting to
create.)

We’d always planned to use the data we collect to enhance
our Personal Analytics system. But I couldn’t resist also
trying to do some basic science with it.

I’ve always been interested in people and the
trajectories of their lives. But I’ve never been able to
combine that with my interest in science. Until now. And
it’s been quite a thrill over the past few weeks to see
the results we’ve been able to get. Sometimes confirming
impressions I’ve had; sometimes showing things I never
would have guessed. And all along reminding me of
phenomena I’ve studied scientifically in A New Kind of
Science.

So what does the data look like? Here are the social
networks of a few Data Donors—with clusters of friends
given different colors. (Anyone can find their own
network using Wolfram|Alpha—or the SocialMediaData
function in Mathematica.)
