Blog Announcement Community ~ gsoc It’s a great news, Gephi has been accepted again for the Google Summer of Code for the 5th year! The program is the best way for students around the world to start contributing to an open-source project. Since 2009, each edition is a great success and dramatically boosted Gephi’s project development. What is Gephi? Networks are everywhere: email systems, financial transaction systems and gene-protein interaction networks are just a few examples. Gephi is a “Photoshop” for graphs: designed to make data navigation and manipulation easy, it covers the entire process from data importing to aesthetics refinements and communication. Gephi’s project aims at providing the perfect tool to visualize and analyze networks. Usability: Easy to install, an UI without scripts and real-time manipulation.Performance: Visualization engine and data structures are built scalable. List of ideas List of ideas are availabe on our wiki. Please also propose your ideas on the forum.
2012 Logo Trends We'll start this trends report—LogoLounge's 10th annual missive—with an admonishment that is repeated each year: If you're searching for how-to information, please stop reading now. In addition, if you anticipate your reaction to reviewing these trends is to dismiss every one of them as yesterday's news, you also may as well walk away right now. There's plenty to be learned here, but you need to be looking for the right thing. After a decade of studying logos from around the world—32,000 alone for this report—I can say with absolute confidence that the true benefit of studying logo design trends is that they invariably identify trajectories. Once you can see the path a trend starts to take, once you can see its arc and velocity, it's very possible for you to know where to take it next. You get to steer. How To Identify a Trend As I review logos that are entered onto the LogoLounge site, three distinct categories start to emerge. Another category is on the opposite side of the universe.
Truthy What is Truthy? Truthy is a research project that helps you understand how memes spread online. We collect tweets from Twitter and analyze them. The name Truthy comes from a term coined by Stephen Colbert, truthiness, which describes claims that feel like they ought to be true, but aren't necessarily. What is a meme? How do you pick the memes for the Election Coverage tool? For the 'Candidates' election coverage selection, we have chosen the top four memes (by tweet volume) that contain "obama" or "biden" to signify the left, and those that contain "romney" or "ryan" for the right. For the 'Politics' selection, we determined the memes based upon the following criteria: #p2: Most popular left-leaning meme #ows: Most popular co-occurring left-leaning meme #topprog: Second most popular co-occurring left-leaning meme #dems: Official hashtag for democrats Of course this is only an illustration of the activity we observe. What is a diffusion network? What is astroturfing?
Dear Data: A Fascinating Year-Long Hand-Drawn Data Visualisation Project Designers Giorgia Lupi (New York) and Stefanie Posavec (London) recently launched a fascinating postcard project called Dear Data. Each week the two data artists measure one aspect of their daily lives and then represent that information with a drawing on a postcard. Every Monday they put their postcards into the mail to journey across the ocean to the other and begin collecting data for the next postcard. Having only met twice in person, this project is as much about the two of them getting to know one another as it is about finding creative ways to record details of their own lives. There are so many interesting details in the notes they make for each other; instructions on how to decode the often extremely abstract ways they’ve represented their findings, as well as little tidbits about their day. The topics they choose for each week vary from people and purchases they make to emotions and the number of times they look at themselves in a mirror or window. Dear Data Project Website
Data Visualization Review: Gephi, Free Graph Exploration Software I do not often get to play with networks, yet I find them fascinating and full of knowledge gathering potential. The data visualization works of Moritz Stefaner, Jer Thorp, and Mark Lombardi captivate me. I am intrigued by relationships, how we perceive them, and how we can understand them. Gephi, the "Open Graph Viz Platform", is not just for the hobbiest node nerd. So what is Gephi capable off? Gephi interface displaying airline traffic data. Pros — Options! Cons — Interface is a bit cluttered. Main interface displaying the Diseasome data. Review Overall, Gephi is a useful and interesting tool. There are some plugins available for Gephi that extend the functionality. The only thing keeping Gephi from being a professional grade tool is its bugginess and lack of documentation. Graph of Minard's data using Gephi and the GeoLayout plugin. For the Purists Gephi is a purist's delight. Two nerdy charts of network statistics that Gephi will output.
Gephi, an open source graph visualization and manipulation software Visible Map of Knowledge Sought This post was written by Jacob McNulty The New York Times recently published this map which shows data searches where users jumped from journal to journal as part of the knowledge they were seeking. What a great visual of knowledge networks in action… What would a map of your workforce look like as they went after the knowledge they needed to do their job? Many organizations are recognizing that the picture above resembles how work gets done in their workforce and leveraging tools such as social or organizational network analysis and value network analysis to create a strategy to support these knowledge networks as ways of transferring knowledge, improving performance and increasing innovation.

Datavisualization.ch Selected Tools Plotting Your Favorite Novels Visually Keywords that most frequently appear in Bram Stoker’s ‘Dracula’ (all images courtesy Matthew Jockers) In the 1967 lecture “Cybernetics and Ghosts,” Italian author and critic Italo Calvino asks us to imagine a machine that composes literature. Would the authorship of the resulting works cheapen their value? Calvino, who follows the structuralist tradition in maintaining that literature is just the combination and recombination of a set of stock elements, thinks not. Others beg to differ. The literature machine may still be a few years away, but the literary criticism machine is already here, at least in one iteration: Matthew Jockers, a professor at the University of Nebraska, is at work compiling data from novels in an attempt to determine whether there’s a set of common plots. Jockers’s work suggests that there are six or seven recurring plots, although when he spoke to Hyperallergic he was careful to clarify that we should be cautious in drawing broader conclusions.

Introduction to behavioral economics Just days ago, President Obama issued this executive order: A growing body of evidence demonstrates that behavioral science insights -- research findings from fields such as behavioral economics and psychology about how people make decisions and act on them -- can be used to design government policies to better serve the American people. So just what is behavioral economics? Well, if you're working on problems that involve people making decisions, you better at least know the basics. (And let's be serious... if a problem doesn't involve human behavior, is it even a problem???) Let's dive in... Traditional economic theory is founded upon the concept of homo economicus (economic man). So what's wrong with the homo economicus model? Well, when we look at the actual choices and behaviors of most people, they don't line up with this model of rational self-interest. Luckily, new theories are emerging to help us understand these poor choices, homo economicus be damned. The brain: two systems
Cytoscape: An Open Source Platform for Complex Network Analysis and Visualization Startups, This Is How Design Works – by Wells Riley logTool: Revealing the Hidden Patterns of Online Surfing Behavior logTool [onformative.com] is a data visualization tool that displays your online activity, based on data from the powerful network packet sniffing tool Carnivore. By analyzing the different IP addresses and ports, the visualization is able to determine and represent what kind of application or service sends or receives the packets. Developed for the magazine Weave, logTool was used to digest the surfing behavior of several interaction designers, artists and developers. The time period of a whole day was split into 288 timeslots, 5 minutes each, represented by a radial bar graph. Both tool and source code can be freely downloaded. See also Nebul.us and EyeBrowse.
