Google announces a new feature that tags and helps "fact checking in large news stories."
Tagged articles will show up in the new story box on news.google.com, as well as in the Google News and Weather app for iOS and Android in the USA and the United Kingdom.
There's a two-pronged approach to detecting fact checking. First Google looks for actual markup in the site's source code. Then Google looks for pages "that follow the commonly accepted criteria for fact checks." You can learn more about the process here.
