Online disinformation and fake media content have emerged as a serious threat to democracy, economy and society. Content verification at scale and in near real-time is currently far from trivial, even for experienced journalists, fact-checkers, human rights activists or media literacy scholars. The WeVerify project aims to develop intelligent human-in-the-loop content verification and disinformation analysis methods and tools. Social media and web content will be analyzed and contextualized within the broader online ecosystem, in order to expose fabricated content, through cross-modal content verification, social network analysis, micro-targeted debunking, and a blockchain-based public database of known fakes.
