In Europe’s Election Season, Tech Vies to Fight Fake News The goal, experts say, is to expand these digital tools across Europe, so the region can counter the fake news that caused so much confusion and anger during the United States presidential election in November, when outright false reports routinely spread like wildfire on Facebook and Twitter. Claire Wardle said that Algorithms will have to do a lot of the heavy lifting when it comes to fighting misinformation, After criticism of its role in spreading false reports during the United States elections, Facebook introduced a fact-checking tool ahead of the Dutch elections in March and the first round of the French presidential election on April 23. After the presidential election in the United States last year, Dean Pomerleau, a computer scientist at Carnegie Mellon University in Pittsburgh, also challenged his followers on Twitter to come up with an algorithm that could distinguish fake claims from real news. Using a database of verified articles and their artificial intelligence expertise, rival groups — a combination of college teams, independent programmers and groups from existing tech companies — already have been able to accurately predict the veracity of certain claims almost 90 percent of the time, Mr. Pomerleau said. That means groups that set up fake news sites in the United States, seeking to profit from online advertising when false claims were shared on social media, are less prevalent in Europe.
