One of these projects, is http://signalnoi.se
We formed Thinkst to work on difficult, interesting problems, and while working on security problems for a well known media organisation, we bumped into (a surprisingly common) problem organisations have: failing to benefit from the available insights afforded by the real-time social media networks.
Signalnoi.se managed to win the Knight Fundation’s News Challenge in 2012 (which we take as pretty good validation for the idea). If you have 3 minutes, checkout the video on the signalnoi.se page. It still shows version-1 of the interface (we have gotten all fancy since!) but should give you a good overview of the product.
