The datasets varied in size, types of content and level of curation. We filtered all URL datasets to include only articles published after 2019 to keep the datasets recent and roughly within the same time frame. If the dataset provided information on the type of fact-checked content, we limited it to the most serious forms of disinformation or disinformation purveyors. For example, Brazil’s Netlab provided a column distinguishing between suspected and confirmed purveyors of disinformation, allowing us to select confirmed purveyors.
