A better ClaimReview to grow a global fact-check database

Google and the Reporters’ Lab have developed an easier method of labelling and logging fact-check articles.

It’s now much easier for fact-checkers to use ClaimReview, a tagging tool that logs fact-checks published around the world into one database. The tool helps search engines — and readers — find non-partisan fact-checks published globally. It also organizes fact-check content into structured data that automated fact-checking will require.

Currently, only half of the roughly 160 fact-checking organizations that the Duke Reporters’ Lab tracks globally use ClaimReview. In response, Google and the Duke Reporters’ Lab have developed an easier method of labelling the articles to help both recruit more users and expand a vital fact-check data set.

The locations of only some fact-checkers tracked by the Reporters’ Lab are visible here. A revised ClaimReview may help more log their fact-checks into a growing, global database.

ClaimReview was created in 2015 after a conversation between staff at Google and Glenn Kessler, the Washington Post fact-checker. Kessler wanted Google to highlight fact-checks in its search results. Bill Adair, director of the Duke Reporters’ Lab,  was soon brought in to help.

Dan Brickley from Schema.org, Justin Kosslyn from Google and Adair developed a tagging system based on the schemas maintained by Schema.org, an organization that develops structured ways of organizing information. They created a universal system for fact-checkers to label their articles to include the claim checked, who said it and a ruling on its accuracy. “It’s the infrastructure that provides the atomic unit of fact-checking to search engines,” Adair said.

Initially, ClaimReview produced a piece of code that fact-checkers copy and pasted into their online content management system. Google and other search engines look for the code when crawling content. Next, Chris Guess of Adair’s team developed a ClaimReview widget called Share the Facts, a content box summarizing fact-checks that PolitiFact, FactCheck.org and the Washington Post can publish online and share on social media.

The latest version of ClaimReview no longer requires users to copy and paste the code, which can behave inconsistently on different content management systems. Instead, fact-checkers only have to fill out Google form fields similar to what they used previously to produce the code.

While the concept of ClaimReview is simple, it opens to the door to more innovation in fact-checking. It organizes data in ways that can be reused. By “structuring journalism, we can present content in more valuable ways to people,” said Adair.

By labeling fact-checks, the creators effectively created a searchable database of fact-checks, numbering about 24,000 today. The main products under development at the Reporters’ Lab, from FactStream to Squash, rely on fact-check databases. Automated fact-checking especially requires a robust database to quickly match untrue claims to previously published fact-checks.

The database ClaimReview builds offers even more possibilities. Adair hopes to tweak the fields fact-checkers fill in to provide better summaries of the fact-checks and provide more information to readers. In addition, Adair envisions ClaimReview being used to tag types of misinformation, as well as authors and publishers of false content. It could also tag websites that have a history of publishing false or misleading articles.

The tagging already is already benefiting some fact-check publishers. “ClaimReview helps to highlight and surface our fact-checks on Google, more than the best SEO skills or organic search would be able to achieve,” said Laura Kapelari, a journalist with Africa Check. ClaimReview has increased traffic on Africa Check’s website and helped the smaller Africa Check compete with larger media houses, she said. It also helps fact-checkers know which facts have already been investigated, which reduces redundant checks.

Joel Luther, the ClaimReview project manager in the Reporters’ Lab, expects this new ClaimReview format will save fact-checkers time and decrease errors when labeling fact-checks. However, there is still room to grow. Kapelari wishes there was a way for the tool to automatically grab key fields such as names in order to save time.

The Reporters’ Lab has a plan to promote ClaimReview globally. Adair is already busy on that front. Early this month, a group of international fact-checkers and technologists met in Durham for Tech & Check 2019, an annual conference where people on this quest share progress on automated fact-checking projects intended to fight misinformation. Adair, an organizer of Tech & Check, emphasized new developments with ClaimReview, as well as its promise for automating fact-checking.

Not much would be possible without this tool, he stressed. “It’s the secret sauce.”
