We know that online collective intelligence can achieve incredible things — for example, the ESP Game, Wikipedia, Mechanical Turk. But many of these systems assume that individuals make independent assumptions and that these judgments can be aggregated. Neither of these are true in Wikipedia, where “truth” is generated through an intense combination of coordination and [...]
Sorry for the stale news if anyone but me knew about this already, but I just discovered how easy it is to have create a temporary hostname, and this is really cool:
Suppose that you’re about to carry out an web-based experiment (called tutor, for instance), and that you don’t want to setup a whole new [...]
Take a look at :
http://www.google.com/views?q=olympics+view%3Amap&esrch=RefinementBarTopViewTabs. They have used a graphical framework that reminds me of exhibit. Interesting that they haven’t explored faceted browsing (for now, still a single search box). On the other hand, within a view you can adjust the lens (i.e: show only dates). Would that be a cool feature to add to [...]

I’ll cover three things in this posts: labels, classes, properties. This post assumes the following three namespaces:
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
@prefix rdfs: [...]
This post was going to be an email to a project mate in my database class, but I found myself wanting to markup the text in HTML so I figured I’d put it here.
Unlike web specifications like HTML, which have only one representation on paper/disk, RDF is just an abstract model — it doesn’t matter [...]
From the tiny city of Bergen, Norway comes, well… pretty much all of the cool TV graphics people will be staring at tonight as the US elections are tallied. A spin-off from the Norwegian television channel TV2, Vizrt was founded in year 2000 near an old sardine factory right down the street from my dad’s [...]

Over the summer I had the sometime pleasure of building a research application on the Facebook platform. In retrospect I’m not sure why more people aren’t doing this — we were able to get thousands of users, lots of data, and roll out the biggest (and highest-stakes) user study of my life.
There are three approaches [...]
