Berkman Center's Media Cloud Tracks Traditional and Citizen-based News Sources

Do bloggers introduce story lines into mainstream media
or the other way around? What parts of the world are being
covered or ignored by different media sources?

These are the kinds of questions that inspired the
Berkman Center for Internet and Society (teamed
with Thomson Reuters) to launch Media Cloud,
an analytical system that lets you track and analyze
the flow of news as it appears in the mainstream media,
citizen media and blogs.

From the Media Cloud homepage:

The Internet is fundamentally altering the way that news is
produced and distributed, but there are few comprehensive
approaches to understanding the nature of these changes.
Media Cloud automatically builds an archive of news stories
and blog posts from the web, applies language processing,
and gives you ways to analyze and visualize the data. The
system is still in early development, but we invite you to
explore our current data and suggest research ideas.
This is an open-source project, and we will be releasing all
of the code soon.
