Adventures in Modularity

I’ve been more engaged with community detection in networks lately.  Community detection, what’s listed as the Modularity option in Gephi’s statistics toolbox and referred to as such in the literature, relies on a variety of methods to try to identify … Continue reading

More Networks in the Humanities or Did books have DNA?

Fortunately, that was a question left to Matt Jockers.  I thought, though, that I might post the slides I used to describe networks in general and the examples using network analysis and representation based on the literature network that Matt … Continue reading

Post Your Graphs with gexf-js

While tools like Gephi allow for easy manipulation and examination of a network, to present such networks you’ll invariably need to export it into a more accessible form.  This can be accomplished using vector imagery, such as PDF; or static … Continue reading

Negotiating the Transition from Topology to Topography in Geographic Networks

Networks are particularly well-suited for representing travel between points using routes that require establishment, investment and maintenance, like the roads found in traditional Roman land routes.  The structure breaks down, though, when it’s applied to travel that does not recognize … Continue reading

Scripted Network Animation, the Ugly Years

I’m a step closer to releasing the code to build network animations using the Gephi Toolkit.  This video, while much uglier than my earlier ones, is distinguished in that every change to the running layout is set up through cues … Continue reading

Animating Networks in Gephi

I thought I’d give a brief overview of the process I’ve been using to build the Gephi network animations I’ve been posting recently.  It’s pretty crude, right now–basically you just run a layout or transformation for a single tick and … Continue reading

Google Networks

Google just announced Ripples,which allows Google+ users to visualize the spread of information across the network.  Scott Weingart gets into some of the details here and references my G+ post on the matter, where I make two claims: 1)  G+ … Continue reading

Yet Another Gephi Workshop

In my ongoing effort to make sure that everyone in the known world is capable of drawing the most aesthetically pleasing circles with lines connecting them, I’ll be holding another Intro to Gephi workshop at Stanford University in Meyer Library … Continue reading

THATCamp Results

Along with my hopefully-not-too-rambling explanation of the ins and outs of Gephi, we built the above network by creating a simple edge list using Google Docs and imported it into Gephi using Import Spreadsheet in the Data Laboratory.

Networks in the Humanities, a Visual Exploration

I’m not very good at keeping a secret, especially when I have draft after draft of Skittles-colored networks to show off, but I tried my best this time to keep this process under my hat until I had something to … Continue reading
