This paper explores multilingual satire detection methods in English and Arabic using zero-shot and chain-of-thought (CoT) prompting. It compares the performance of Jais-chat(13B) and LLaMA-2-chat(7B) on distinguishing satire from truthful news. Results show that CoT prompting significantly improves Jais-chat's performance, achieving an F1-score of 80% in English. Why it matters: This demonstrates the potential of Arabic LLMs like Jais to handle nuanced language tasks such as satire detection, which is critical for combating misinformation in the region.
This paper presents team SPPU-AASM's hybrid model for Arabic sarcasm and sentiment detection in the WANLP ArSarcasm shared task 2021. The model combines sentence representations from AraBERT with static word vectors trained on Arabic social media corpora. Results show the system achieves an F1-sarcastic score of 0.62 and a F-PN score of 0.715, outperforming existing approaches. Why it matters: The research demonstrates that combining context-free and contextualized representations improves performance in nuanced Arabic NLP tasks like sarcasm and sentiment analysis.

This paper introduces a new task: detecting propaganda techniques in code-switched text. The authors created and released a corpus of 1,030 English-Roman Urdu code-switched texts annotated with 20 propaganda techniques. Experiments show the importance of directly modeling multilinguality and using the right fine-tuning strategy for this task.
