The data used for creating the Twitter dataset is obtained from the Poynter Coronavirus Fact Alliance. The alliance consists of 101 fact-checking organisation based in 1000 countries and covering 46 languages.
The largest amount of fact-checked content comes from English (8,706 fact-checks) and the least is Finland (1 fact-checks). Most fact-checked content is in Spanish (4,577) followed by Portuguese (2,801) and Ukrainian (2,073) (Figure 3).
Determining a direct impact of fact-checking on the spread of misinformation is not easy. However, it is possible to determine how well a particular corrective information is spreading in relation to its corresponding misinformation.
Figure 5 shows how misinformation and fact-checking content has spread in various topics for the last two analysis periods and overall.
Using automatic methods, Twitter account demographics are extracted for user age, gender and account type (i.e., identify if an account belong to an individual or organisation).
Figure 6 displays how misinformation and fact-checks are spread by different demographics.
