Google has added a Fact Check tag to its News service to help users distinguish fact from fiction.
The service, which aggregates stories from a variety of sources, already uses labels like Highly Cited, Featured, Opinion and In Depth to categorise the output.
Now, Fact Check will help readers "find fact checking in large news stories", Google's head of news Richard Gingras said. Websites with a fact checking service can apply to be included alongside Google News search results.
"You'll see the tagged articles in the expanded story box on news.google.com and in the Google News & Weather iOS and Android apps, starting with the US and the UK," Mr Gingras said.
“Over the last several years, fact checking has come into its own. Led by organisations like the International Fact-Checking Network, rigorous fact checks are now conducted by more than 100 active sites, according to the Duke University Reporter’s Lab,” he added.
“They collectively produce many thousands of fact-checks a year, examining claims around urban legends, politics, health, and the media itself.”
Google News determines whether an article might contain fact checks by looking for a mark-up called ClaimReview. It will also look for websites that follow accepted criteria for fact checks.
