Where Are the Facts? Searching for Fact-checked Information to Alleviate the Spread of Fake News

Although many fact-checking systems have been developed in academia and\nindustry, fake news is still proliferating on social media. These systems\nmostly focus on fact-checking but usually neglect online users who are the main\ndrivers of the spread of misinformation. How can we use fact-checked\ninformation to improve users' consciousness of fake news to which they are\nexposed? How can we stop users from spreading fake news? To tackle these\nquestions, we propose a novel framework to search for fact-checking articles,\nwhich address the content of an original tweet (that may contain\nmisinformation) posted by online users. The search can directly warn fake news\nposters and online users (e.g. the posters' followers) about misinformation,\ndiscourage them from spreading fake news, and scale up verified content on\nsocial media. Our framework uses both text and images to search for\nfact-checking articles, and achieves promising results on real-world datasets.\nOur code and datasets are released at https://github.com/nguyenvo09/EMNLP2020.\n
