Abstract

The propagation of fake news may influence a large number of people on a wide range of subjects. Once the spread of fake news reached a critical point, relevant initiatives to fight them have emerged. In this paper, we adapt from English a knowledge graph-based method for fact-checking and propose a new one based on Google search, following content-based strategies for tackling deception in Portuguese, differently from what has been previously done in linguistic-based approaches. Our results are promising and indicate new ways to deal with the deceptive content detection issue.
