| Resumen |
In recent years, we have seen an increase in conspiracy theories on social media. Users create these ideas mainly due to ignorance and distrust of government indices. These types of problems became prominent during the Covid-19 pandemic, representing a serious public health issue. This year, PAN 2024 has organized the task "Oppositional thinking analysis: Conspiracy theories vs critical thinking narratives", to present at CLEF 2024, in which we participated. For this task, we present a solution using a BERT configuration, with a preprocessing layer that has previously given us good results for various types of classification. We also tried combinations of n-grams of words (2-3-4) and characters (2-3-4-5). © 2024 Copyright for this paper by its authors. |
