DETESTS-Dis IberLEF 2024

The DETESTS-Dis task will take place as part of IberLEF 2024, the 6th Workshop on Iberian Languages Evaluation Forum at SEPLN 2024 conference, which will be held on September 24th, 2024 in Valladolid (Castilla y León, Spain).

One of the components that reinforce toxic and hateful speech are stereotypes. Understanding how they emerge and spread is crucial for tackling this issue, since stereotypes are not always expressed explicitly. The presence of stereotypes on social media and the need to identify and mitigate them is leading to the development of systems for their automatic detection, especially in news comments. This is, therefore, a new task that is attracting growing interest from the NLP community.

Here, we introduce the second edition of the DETESTS task (Ariza-Casabona et al., 2022), which was first presented at IberLEF 2022. The aim of the new edition, DETESTS-Dis, is to detect and classify explicit and implicit stereotypes in texts from social media and comments on news articles, incorporating learning with disagreement techniques. Moreover, participants will be given the gold standard or hard labels, as well as the pre-aggregated labels, following the Learning with Disagreement paradigm (Uma et al., 2021; Leonardelli et al., 2023). The texts consist of whole tweets (now known as X posts) published in response to verified racial hoaxes (a type of fake news), and sentences extracted from comments on online news articles related to immigration, all in Spanish.
