RoCoFake – A Romanian Covid-19 Fake News Dataset

ABSTRACT

The Covid-19 pandemic, managed to shed light onto a neglected problem – that of fake news. Even though lockdowns were imposed in most parts of the world, collaboration between researchers across the globe wasn't impeded. Moreover, the lockdown has deprived people of face-to-face interactions and so they shifted towards online communication. This translated into a massive chatting data, which part was true, but fake information also had its share. Therefore, it is of great interest to develop a dataset to try to spot the fake information. RoCoFake comes to address the lack of resources in this domain, by providing a Romanian Covid-19 Fake News dataset, by aggregating various resources available online, like tweets, news titles and fact-checking news sites like factual.ro. This data provides researchers from the medical domain particularly, but not only, with a valuable, open-access data source useful for various research projects. A benchmark for fake news detection is also provided, so that future investigations can compare against our research. Results suggest that even though the dataset is relatively large, improvements can be made by incorporating retweets and comments. © 2022 IEEE.
