README.markdown

This is the source code for the Media Cloud core system. Media Cloud, a joint project of the Berkman Center for Internet & Society at Harvard University and the Center for Civic Media at MIT, is an open source, open data platform that allows researchers to answer complex quantitative and qualitative questions about the content of online media.

For more information on Media Cloud, go to mediacloud.org.

Note: Most users prefer to use Media Cloud's API and public tools to query our data instead of running their own Media Cloud instance.

The code in this repository will be of interest to those users who wish to run their own Media Cloud instance and users of the public tools who want to understand how Media Cloud is implemented.

The Media Cloud code here does three things:

  • Runs a web app that allows you to manage a set of media sources and their feeds.

  • Periodically crawls the feeds setup within the web app and downloads any new stories found within the downloaded feeds.

  • Extracts the substantive text from the downloaded story content (minus the ads, navigation, comments, etc.) and associates a set of tags with each story based on that extracted text.

For very brief installation instructions, see INSTALL.markdown.

Please send us a note at info@mediacloud.org if you are using any of this code or if you have any questions. We are very interested in knowing who's using the code and for what.

History of the Project

Print newspapers are declaring bankruptcy nationwide. High-profile blogs are proliferating. Media companies are exploring new production techniques and business models in a landscape that is increasingly dominated by the Internet. In the midst of this upheaval, it is difficult to know what is actually happening to the shape of our news. Beyond one-off anecdotes or painstaking manual content analysis, there are few ways to examine the emerging news ecosystem.

The idea for Media Cloud emerged through a series discussions between faculty and friends of the Berkman Center. The conversations would follow a predictable pattern: one person would ask a provocative question about what was happening in the media landscape, someone else would suggest interesting follow-on inquiries, and everyone would realize that a good answer would require heavy number crunching. Nobody had the time to develop a huge infrastructure and download all the news just to answer a single question. However, there were eventually enough of these questions that we decided to build a tool for everyone to use.

Some of the early driving questions included:

  • Do bloggers introduce storylines into mainstream media or the other way around?
  • What parts of the world are being covered or ignored by different media sources?
  • Where do stories begin?
  • How are competing terms for the same event used in different publications?
  • Can we characterize the overall mix of coverage for a given source?
  • How do patterns differ between local and national news coverage?
  • Can we track news cycles for specific issues?
  • Do online comments shape the news?

Media Cloud offers a way to quantitatively examine all of these challenging questions by collecting and analyzing the news stream of tens of thousands of online sources.

Using Media Cloud, academic researchers, journalism critics, policy advocates, media scholars, and others can examine which media sources cover which stories, what language different media outlets use in conjunction with different stories, and how stories spread from one media outlet to another.
