Media Cloud

Media Cloud is a consortium research project across multiple institutions, including the Berkman Klein Center for Internet & Society at Harvard University, the University of Massachusetts Amherst, and Northeastern University. It is an open source, open data platform that allows researchers to answer complex quantitative and qualitative questions about the content of online media. Using MediaCloud, academic researchers, journalism critics, and interested citizens can examine what mediasources cover which stories, what language different media outlets use in conjunction with different stories, and how stories spread from one media outlet to another.

For more information and to get started, visit the Media Cloud site at mediacloud.org.
