Bipartite Network gets a Makeover

I guess my research is slowly changing focus and is more and more about some kind of data science (although I still bill myself as a physicist turned network scientist). While statistics and mathematical models are still driving this type of research, an increasingly important part of data science is visualization – finding neat ways… Continue reading Bipartite Network gets a Makeover

Worlds Colliding. Part II

Back in March, I wrote a post entitled Worlds Colliding explaining the failure of Google Buzz as a failure to understand the fundamental structure of complex networks.

Mood, twitter, and the new shape of America

Twitter is a gigantic repository for our collective state of mind. Every second, thousands of tweets reveal what everybody and their mother had for lunch, what Justin Bieber is up to, or what magnificent link you should be checking out right now.

The scientific version of the Bacon number is the Erdös number. Via a post on Finn Nielsen’s blog, I learned that i have a reasonably low Erdös number – three.

An animation

A couple of days ago, David Lazer asked me to help him generate an animation of the spread of MFN (trade) treaties in the 1860s. His resulting post on The emergence of international order: The case of MFN treaties in the 1860’s is worth a read! Also, David’s post sparked a nice follow up blog… Continue reading An animation

Starting a real page

I wanted to start a real page, to upgrade from my somewhat one-dimensional page over on http://www.imm.dtu.dk/~slj. As you can probably see, I’m far from done, but I will be updating the site and posting more in the following few days/weeks.

Worlds Colliding

During a press conference at last week’s SxSW conference, product manager of Google’s gmail team, Todd Jackson, revealed an interesting bit of information about the company’s problem-ridden new service Google Buzz: Jackson told the crowd, as he’s previously said to reporters, that too much was assumed about how Buzz would work best and be received… Continue reading Worlds Colliding
