nik / py-diffbot py-diffbot is a command line terminal client and python library for the Diffbot article extraction and analysis API. Developer Token To use the client or Python library you will need to include a developer token, which can be obtained by submitting a request at the Diffbot website. Getting Source $ hg clone diffbot Command Line Client Data Wrangler UPDATE: The Stanford/Berkeley Wrangler research project is complete, and the software is no longer actively supported. Instead, we have started a commercial venture, Trifacta. For the most recent version of the tool, see the free Trifacta Wrangler. Why wrangle? Too much time is spent manipulating data just to get analysis and visualization tools to read it.
Six Degrees of Wikipedia Six Degrees of Wikipedia is a Harvard CS205 class project aimed at analyzing and understanding the structure of the English Wikipedia . The project was inspired by similar projects such as the Oracle of Bacon (which modeled the popular trivia game Six Degrees of Kevin Bacon ), Microsoft Academic Map (which visualized the concept of Erdos numbers ) and a 2008 version of Six Degrees of Wikipedia . Similar to these projects, our analysis goes beyond exploring the Six Degrees of Separation concept and attempts to provide insights into the overall graph structure of Wikipedia. The following 2-minute video presents the major components of the project:
Sage - Tour Sage is built out of nearly 100 open-source packages and features a unified interface. Sage can be used to study elementary and advanced, pure and applied mathematics. This includes a huge range of mathematics, including basic algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, exact linear algebra and much more. It combines various software packages and seamlessly integrates their functionality into a common experience. It is well-suited for education and research. Could A Tool Like This Turn Every M.D. Into Dr. House? When you visit the doctor complaining of a cough or stomach pain, they usually seem to know what to do: They'll ask if you have trouble breathing, or check your heart rate. But it's all a little baffling: What are they checking for? What illnesses could it be? This remarkable new infographic by GE, working with MIT's SENSEable City Lab, peels back how various symptoms of illness are linked, giving you a tantalizing look into the mind of a doctor. The interactive chart is powered by 7.2 million medical records, gathered between 2005 and 2010. Using these, MIT's data wizards were able to figure out how often one symptom was linked to another.
