Have you ever wondered whether a story is original journalism, or merely a tweaked version of a story that previously appeared elsewhere? The Sunlight Foundation has just released a new tool to detect “churnalism”:

Today, the Sunlight Foundation has unveiled a tool that will help us all with this work. “The tool is, essentially, an open-source plagiarism detection engine,” web developer Kaitlin Devine explained to me. It will scan any text (a news article, e.g.) and compare it with a corpus of press releases and Wikipedia entries. If it finds similar language, you’ll get a notification of a detected “churn” and you’ll be able to take a look at the two sources side by side. You can also use it to check Wikipedia entries for information that may have come from corporate press releases.
