CALL FOR PARTICIPATION

IberLEF 2022 Task: DETESTS (DETEction and classification of racial Stereotypes in Spanish)

This task will take part of IberLEF 2022<https://sites.google.com/view/iberlef2022>, the 4th Workshop on Iberian Languages Evaluation Forum at the SEPLN 2022 Conference, which will be held in A Coruña, Spain, on September 20th.

The aim of the task is to detect and classify stereotypes in sentences from comments posted in Spanish in response to different online news articles related to immigration. The task is designed in a hierarchical fashion by chaining two subtasks:

* ​Subtask 1: Participants tackling this problem will have to determine whether a sentence contains at least one stereotype or none considering the full distribution of labels provided by the annotators based on the proposal of learning with disagreements. The actual gold label of this subtask is left as a proxy to determine the subset of sentences that will be evaluated in the posterior subtask.

* Subtask 2: This subtask consists of determining whether a sentence contains at least one stereotype or none and assigning those sentences previously marked as positive (with stereotypes) to ten categories. Since a sentence can contain multiple stereotypes belonging to different categories, this subtask will be presented as a multi-label hierarchical classification problem.

Participants are allowed to participate just in one of them (e.g., subtask 1). Teams will be allowed (and encouraged) to submit multiple runs (max. 5).

The present task is proposed to participants interested in racial, national, or ethnic stereotype detection and classification tasks. Furthermore, the annotated dataset is a valuable resource for exploratory linguistic analysis, as well as for comparing the application of deep learning and classical machine learning models on Spanish stereotyped expressions under the recently introduced learning with disagreements paradigm. Participants will be provided with the annotated data by each of the annotators and the gold standard.

Linguistic resources:

Our DETESTS corpus consis made up of comments (at least 50) segmented onto sentences published in response to manually selected articles extracted from Spanish online newspapers. The common topic of all articles is immigration. It consists of 5,629 sentences. We will provide participants with 70% of the dataset to train their models, while the remaining 30% will be used to test their models.

To avoid any conflict with the sources of the comments regarding their intellectual property rights (IPR), the data will be sent privately to each participant who is interested in the task. The corpus will only be made available for research purposes.
