Mary Ellen Bates offers up this good tip on “Google Squared” at Bates Information Services, www.BatesInfo.com/tip.html ________________________________________________________________________________________
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” or “area code 909”. Rather, Google analyzes the retrieved pages, identifies common elements, and creates a table with the information it has compiled.
This is a fascinating tool that helps you compile facts into tables that Google builds on the fly. Hard to describe, easier to show. Go to Google.com/squared and type in a query that will retrieve a number of similar things — organic farms in Colorado, for example, or women CEOs… even superhero powers.
Google Squared generates a table of facts extracted from its index, with the items you are searching for as the left-most column, along with columns for whatever related characteristics are relevant for the topic. For organic farms in Colorado, for example, the table in the search results has columns for the name of the company, an image from the farm's web site, a snippet of description about the farm, and columns for telephone number, location and “season.” Note that some of these columns may have few entries in them, depending on what information Google analyzed. For women CEOs, the table includes the CEO's name, a photo, a snippet that indicates what her position is, her date of birth, and her nationality. For superhero powers, you will find the superhero's name, a photo, a far-too-brief description of said superhero, the hero's first appearance (in print, that is), publisher and even the hero's “abilities”.
Interestingly, you can insert your own items in a Google Squared table, and either let Google populate the rest of the row or type in whatever content you want in that row. I added Catwoman to my superheroes table and Google filled in the new row with her photo and description; I could provide the rest of the info. For some tables, Google even suggests additional columns. For my superheroes table, I could add columns for Aliases, Alter Ego, Profession (the Joker is a lawyer, of course), and so on. You can add your own columns, as well.
You can also delete a row or column that isn't relevant to your search. If you log in to your Google account, you can save your customized tables for later use. And you can export the table into Excel (the images are exported as URLs).
Google Squared is never going to compete with a real human's analysis of a collection of facts, but it can be a great way to start brainstorming, as a quick way to organize the results of your search, and as a starting point for a nicely-presented deliverable for your client.

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.
“Social Network Analysis in R — video and slides for talk on doing social network analysis with R.”
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.
Social Netowork Analysis in R from Drew Conway on Vimeo.
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.
Good NYTimes profile of NYU/Hoover Institute professor Bruce Bueno de Mesquita, who has spent 40+ years developing predictive models of socio-political activity. (Also a nice bit of promo for “The Predictioneer’s Game,” Bueno de Mesquita's book scheduled to come out next month.)
“Of course, a somewhat high profile always proves to be an attractor. For example, see “The New Nostradamus.” “Can a fringe branch of mathematics forecast the future? A special adviser to the CIA, Fortune 500 companies, and the U.S. Department of Defense certainly thinks so. “If you listen to Bruce Bueno de Mesquita, and a lot of people don’t, he’ll claim that mathematics can tell you the future. In fact, the professor says that a computer model he built and has perfected over the last 25 years can predict the outcome of virtually any international conflict, provided the basic input is accurate. What’s more, his predictions are alarmingly specific. His fans include at least one current presidential hopeful, a gaggle of Fortune 500 companies, the CIA, and the Department of Defense. Naturally, there is also no shortage of people less fond of his work. “Some people think Bruce is the most brilliant foreign policy analyst there is,” says one colleague. “Others think he’s a quack.”

Still, we think the articles and approach are well-worth your reading time.
FYI from O'Reilly Radar.
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?
Enabling Massively Parallel Mathematics Collaboration — Jon Udell writes about Mike Adams whose WordPress plugin to grok LaTeX formatting of math has enabled a new scale of mathematics collaboration.

===============================================
Polymath = user innovation Posted by Jon Udell under Uncategorized [9] Comments 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: $latex \pi r^2$ And produce this: When he introduced the feature, Mike wrote: 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.
