integration with Check

The Check team is pleased to announce that we now integrate with’s ClaimReview schema to extract structured data from articles added to Check. is a structured data markup schema supported by major search engines. Why structured data? Well, machines respond much better to formal data, so is really a way to help those machines that index the web, or applications like Check that pay attention to structured data on a web page, better understand the information provided by a web-page.

Taking the effort to recognize ClaimReview metadata on links brought to Check is not, it should be emphasized, a ‘killer’ feature, but it is the first modest step of our broader structured data strategy — the forward thinking on which is expressed in our work developing a set of Credibility Indicators through the Credibility Coalition (

With this first step we now recognize and automatically extract into the UI plain text display of: an identified claim; the source of the claim; who worked to verify or debunk it; and the status assigned to the claim.

The major search engines, Google, Bing, Yahoo! and Yandex, all participate in the development and governance of, and have begun to express ClaimReview data into search results. Here is an example return for ‘the world is flat’ search on Google:

ClaimReview data presented on Google search results

Here’s how Google describes it:

If you have a web page that reviews a claim made by others, you can include a ClaimReview structured data element on your web page. This element enables Google Search results to show a summarized version of your fact check when your page appears in search results for that claim.

The ClaimReview schema allows for much more than showing up on search results on major platforms. Our friend Sreya Guha, for example, developed a tool called Related Fact Checks that allows you to search for related fact checks. The Share the Facts widget developed by the Duke Reporters Lab and Jigsaw allows you to more easily share this data is standardized boxes.

The Share the Facts widget allows for a simple, streamlined display of the data.

With this latest addition to Check, we are beginning our march toward the bot, or machine process, enhanced future of Check — a vision that we have already begun to express with features like automated reverse image search, automated screenshotting, and automated archiving to with Keep. This is also part of our longer-term work with the Oxford Internet Institute and engineers like Ms Gupta on political and scientific claims, work which will address claims discovery, deduplication, and indexing in Check.

Being at the center of the open source development community working to address the mis and disinformation, we are placing much social and organizational capital behind the bet that the web needs a machine — and human — readable context layer. Agreeing on the standards we use to describe context relevant to the veracity or credibility of a claim, source, image, or link is a critical piece of the daunting and complex task of improving the web. We are pleased to release this first baby step on our path to improving the way knowledge is described and shared by humans and machines.
