Google Squared
Google Labs -- the public playground where Google lets users try out new products or services that aren't yet ready for prime time -- is my secret weapon for learning about cool new stuff. My favorite new discovery in Google Labs is Google Squared. It's a demonstration of a search engine trying to provide answers instead of just sites, and at a higher level than the simple "smart answers" you see when you search for "time in Rome" ... more»
OK, OK. Using R can be a steep hill to climb for some. But here, thanks to O"Reilly Radar, is a pretty good video of a presentation on using R as a Social Network Analysis tool.
Update II: It occurred to me that it would be much better for people to be able to view the entire talk in a single video, rather than having to switch between sections; therefore, I uploaded the whole thing to Vimeo.
Tonight I will be givingOn August 6th I gave a talk at the New York City R Meetup on how to perform social network analysis in R using the igraph package. Below are the slides I will be going over covered during the talk, and all of the code examples from the presentation are available in the ZIA Code Repository in the R folder.
Below is a video of this talk, with a link to the slides I review during the presentation. If you are interested, I suggest downloading the slides and following along with videos while having the slides open, as much of what is on the screen in the video is hard to read.
Andrew Little’s presentation on econometrics in R using Zelig and MatchIt are also available on YouTube starting here. I hope you enjoy the presentation, and please let me know if you have any questions or comments.
And does this suggest possibility of something like "distributed data analysis" whereby a number of widely scattered watchdogs could be poking into the same data set? If so, raises interesting questions for journalism educators: who is developing the tools to manage such investigations?
In February 2007, Mike Adams, who had recently joined Automattic, the company that makes WordPress, decided on a lark to endow all blogs running on WordPress.com with the ability to use LaTeX, the venerable mathematical typesetting language. So I can write this:
Odd as it may sound, I miss all the equations from my days in grad school, so I decided that what WordPress.com needed most was a hot, niche feature that maybe 17 people would use regularly.
A whole lot more than 17 people cared. And some of them, it turns out, are Fields medalists. Back in January, one member of that elite group — Tim Gowers — asked: Is massively collaborative mathematics possible? Since then, as reported by observer/participant Michael Nielsen (1, 2), Tim Gowers, Terence Tao, and a bunch of their peers have been pioneering a massively collaborative approach to solving hard mathematical problems.
Reflecting on the outcome of the first polymath experiment, Michael Nielsen wrote:
The scope of participation in the project is remarkable. More than 1000 mathematical comments have been written on Gowers’ blog, and the blog of Terry Tao, another mathematician who has taken a leading role in the project. The Polymath wiki has approximately 59 content pages, with 11 registered contributors, and more anonymous contributors. It’s already a remarkable resource on the density Hales-Jewett theorem and related topics. The project timeline shows notable mathematical contributions being made by 23 contributors to date. This was accomplished in seven weeks.
Just this week, a polymath blog has emerged to serve as an online home for the further evolution of this approach.
