Evaluating ChatGPT’s Ability to Detect Hate Speech in Turkish Tweets

Proceedings of the 7th Workshop on Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE 2024)

ChatGPT, developed by OpenAI, has made a significant impact on the world, mainly on how people interact with technology. In this study, we evaluate ChatGPT’s ability to detect hate speech in Turkish tweets and measure its strength using zero- and few-shot paradigms and compare the results to the supervised fine-tuning BERT model. On evaluations with the SIU2023-NST dataset, ChatGPT achieved 65.81% accuracy in detecting hate speech for the few-shot setting, while BERT with supervised fine-tuning achieved 82.22% accuracy. This results supports previous findings that show that, despite its much smaller size, BERT is more suitable for natural language classifications tasks such as hate speech detection.

This paper offers an overview of Hate Speech Detection in Turkish and Arabic Tweets (HSD-2Lang) Shared Task at CASE workshop to be held jointly with EACL 2024. The task was divided into two subtasks: Subtask A, targeting hate speech detection in various Turkish contexts, and Subtask B, addressing hate speech detection in Arabic with limited data. The shared task attracted significant attention with 33 teams that registered and 10 teams that participated in at least one task. In this paper, we provide the details of the tasks and the approaches adopted by the participant along with an analysis of the results obtained from this shared task.

Proceedings of the 7th Workshop on Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE 2024)

In this paper, we provide a brief overview of the 7th workshop on Challenges and Applications of Automated Extraction of Socio-political Events from Text (CASE) co-located with EACL 2024. This workshop consisted of regular papers, system description papers submitted by shared task participants, and overview papers of shared tasks held. This workshop series has been bringing together experts and enthusiasts from technical and social science fields, providing a platform for better understanding event information. This workshop not only advances text-based event extraction but also facilitates research in event extraction in multimodal settings.
