NYTimes, on Memetracker, and Spinn3r

I didn't have time to blog about this when it was originally posted but the NYTimes has a great piece on the cool work done by Jure Leskovec and Jon Kleinberg with their work on Memetracker (which is powered by Spinn3r).

For the most part, the traditional news outlets lead and the blogs follow, typically by 2.5 hours, according to a new computer analysis of news articles and commentary on the Web during the last three months of the 2008 presidential campaign.

The finding was one of several in a study that Internet experts say is the first time the Web has been used to track — and try to measure — the news cycle, the process by which information becomes news, competes for attention and fades.

Researchers at Cornell, using powerful computers and clever algorithms, studied the news cycle by looking for repeated phrases and tracking their appearances on 1.6 million mainstream media sites and blogs. Some 90 million articles and blog posts, which appeared from August through October, were scrutinized with their phrase-finding software.
