    Q: What is ClaimReview?

    Schema.org's ClaimReview is an open standard schema that was designed by the fact checking community to encode essential information about a fact check in a structured format. It has been adopted by many fact checkers around the world, including those verified by IFCN. This wide adoption of ClaimReview enabled major platforms to power fact check features inside their products, such as Google News, Google Search, Bing Search, Facebook.

    Q: What data is included in the research dataset ?

    The data in the research data set includes structured markup of fact checking articles, that the publishers have associated with their articles. Each line is an individual markup that follows the ClaimReview schema and includes the url field that points back to the original fact checking articles. The content of the fact checking article is not part of the release.

    The released dataset of ClaimReview markups is a subset of ClaimReview markup available on the Web and is not representative of the entire schema.org markups ClaimReview available on the web. As the fact checking community grows, we expect the size of the released dataset will grow in future versions.

    The Fact Check Markup Tool data feed is refreshed daily.
