The following markup is proposed for use by a collaboration amongst fact-checking sites.

It adds vocabulary around Review to make more explicit when these are from fact-checking sites:

  • 1.) ClaimReview as a subtype of Review. "A fact-checking review of claims made in some creative work."
  • 2.) claimReviewed as a property of ClaimReview. "A short summary of the specific claims reviewed in a ClaimReview."
  • 3.) It uses the existing 'author' property on Review to indicate the organization behind the review.
  • 4.) It uses a new property, claimReviewSiteLogo on the (Claim)Review to indicate the fact-checking organization's logo.
  • 5.) It uses the existing itemReviewed property to indicate the document that carries the claims being reviewed (which could include as shown here, offline newspaper articles).

Example

(updated for Feb 2017 but original was close)

<script type="application/ld+json">
{
    "@context": "http://schema.org",
    "@type":  "ClaimReview",
    "datePublished": "2014-07-23",
    "url": "http://www.politifact.com/texas/statements/2014/jul/23/rick-perry/rick-perry-claim-about-3000-homicides-illegal-immi/",
    "author": {
        "@type": "Organization",
        "url": "http://www.politifact.com/",
        "sameAs": "https://twitter.com/politifact"
    },
    "claimReviewed": "More than 3,000 homicides were committed by \"illegal aliens\" over the past six years.",
    "reviewRating": {
        "@type": "Rating",
        "ratingValue": 1,
        "bestRating": 6,
        "alternateName": "True",
        "image": "http://static.politifact.com/mediapage/jpgs/politifact-logo-big.jpg"
    },
    "itemReviewed": {
        "@type": "CreativeWork",
        "author": {
            "@type": "Person",
            "name": "Rich Perry",
            "jobTitle": "Former Governor of Texas",
            "image": "https://upload.wikimedia.org/wikipedia/commons/thumb/1/15/Gov._Perry_CPAC_February_2015.jpg/440px-Gov._Perry_CPAC_February_2015.jpg",
            "sameAs": [
                "https://en.wikipedia.org/wiki/Rick_Perry",
                "https://rickperry.org/"
            ]
        },
        "datePublished": "2014-07-17",
        "name": "The St. Petersburg Times interview [...]"
    }
}
</script>

Suggestions:

  • Instead of 'twitter' as a property, use 'sameAs' with full URL.
  • Can we use 'logo' of the Organization instead of claimReviewSiteLogo?
  • What is "text": "True" for?
  • The example has "image" : "http://static.politifact.com/mediapage/jpgs/politifact-logo-big.jpg" on the Rating - seems redundant as that URL is already in there.
  • sourceName should probably be just 'name', but we could distinguish the source article versus its publisher explicitly.
  • Use 'jobTitle' rather than 'title' (for "Former Governor of Texas")

An update on adoption of this vocabulary, for those who might have missed it. If you inspect (via in-browser element inspection) the post-Javascript DOM of URLs such as

http://www.factcheck.org/2016/07/groundhog-friday-7/
http://www.politifact.com/truth-o-meter/article/2016/may/17/fact-checking-pro-clinton-super-pacs-attacks-donal/
https://www.washingtonpost.com/news/fact-checker/wp/2016/06/17/fact-checking-three-democratic-claims-on-assault-rifles-and-guns/

you will see Widget-injected JSON-LD using the ClaimReview type, and that augments the Rating item with (in the last case) a 'name' property that carries non-numeric codes, e.g.

"reviewRating": {
   "@type": "Rating",
   "ratingValue": "2",
   "bestRating": "5",
   "name": "Two Pinocchios",
   "image" : "https://s3.amazonaws.com/share-the-facts/rating_images/washpo/washpo_pinnochios_2.png"
 },

See also https://github.com/ReportersLabDuke/Widget/ which has related widget code.

I mention this in part because of nearby discussion (#668 #915 and most recently #780) around the question of representing awards, "star ratings" (esp. for accomodation) and other endorsements, and how general vs domain specific we want various constructions to be.

The point of overlap (beyond the general connection to the notion of Review and/or Rating) is that the fact checking sites have situations such as "Two Pinocchios" in which a well known (and site/provider-specific) informal but named code is applied to something. The broadly analogous situation with awards is that something is awarded "critic's pick", "x of the year" etc., which can be conceived of as a kind of rating. Meanwhile schema.org/Rating defaults to 5-point scales.

Despite that discussion, my feeling is that ClaimReview has proved its worth and the design seems reasonably stable. I suggest we move it into the core (it is currently staged in pending.schema.org) to encourage further adoption.

Given the relatively small number of sites in the fact-checking audience, I believe having politifact, factcheck.org and the Washington Post is excellent progress. I'll proceed with moving this into Core just as soon as we figure out how exactly to structure this technically (so that the old URLs are still useful). /cc @shankarnat @tmarshbing @chaals @nicolastorzec @scor @mfhepp @rvguha @vholland in case anyone cares to suggest another course of action.

Just thought I'd mention that this proposal gets a mention in the recent fullfact.org "State of Automated Factchecking" report in case that adds fuel to the fire of getting it moved into schema.org core.

Oh, that is nice, thanks @bquinn. Makes a change from reading about "post factual" democracy...

For reference:

Google News suggests to use ClaimReview in their blog post Labeling fact-check articles in Google News (link to pending) and in their help about source labels (Fact Check) (link core, where the type does not yet exist).

This is because it is a general image for Politifact, not an icon

Suggestion, it would be helpful to include a property for a link to a source for where the claim is made. Most fact checking articles include such a link to an original piece of news reporting or a primary source that is the origin (or close to the origin) of the claim.

@thinkcontext The description of ClaimReview suggests to reference the work where the claim is made with the itemReviewed property.

For example:

<article vocab="http://schema.org/" typeof="ClaimReview">
  <h2 property="name">Fact check: Foo (example.com)</h2>

  <div property="itemReviewed" typeof="Article">
    <a property="url" href="http://example.com/articles/foo"><cite property="name">Foo</cite></a>
  </div>

</article>

Does this work for you?

@thinkcontext

I see, thanks for that clarification @unor

Support Google fact-check tag #3

@melvincarvalho

The use of sameAs in the example, seems kind of problematic, particularly in the context of reviews.

I might like Ricky Martin's home page, but not like Ricky Martin.
