REGLAT at ArGuard Shared Tasks: An Ensemble-Based Model Integrating NER for Harmful Content Detection in Arabic

Read the original on arXiv Computation and Language →

The paper introduces REGLAT, an ensemble-based model that integrates named entity recognition (GLiNER) with a fine‑tuned MARBERT classifier to detect harmful content in Arabic. It classifies user prompts into seven harm categories, achieving a macro‑F1 of 0.886 and accuracy of 0.897 on the ArGuard 2026 development set, with slightly lower scores on blind test sets. The study highlights that combining explicit entity extraction with contextual language modeling improves fine‑grained harmful content detection, though distinguishing closely related categories remains difficult.

ArGuard Shared Task: Harmful Content Detection in Arabic Memes and LLM Prompts

ArGuard is a shared task that evaluates harmful content detection in Arabic memes and LLM prompts, featuring two tracks: Track A for multimodal hate detection in memes and Track B for harmful prompt detection in Arabic LLM safety evaluation. Fifty‑eight teams registered, 35 reached the final evaluation, and 27 submitted system‑description papers, with participants experimenting with models such as AraBERT, Jais, and Qwen3‑VL. The top systems achieved macro‑F1 scores of 0.823 on A1, 0.419 on A2, 0.984 on B1, and 0.790 on B2, with fine‑grained meme classification in A2 proving the most challenging due to sparse labels and distribution shifts.

AHA-Memes: A Fine-Grained Multimodal Benchmark for Understanding Hate in Arabic Memes

Hateful memes are a growing form of multimodal online harm, where hostile intent is often conveyed through the joint interpretation of images, text, cultural references, and implicit targets. While hateful meme detection has advanced in high-resource languages, Arabic remains underexplored, with existing meme resources focusing mainly on propaganda or coarse harmful-content labels.

SZED at ArGuard Shared Tasks: Multi-Task Label-Attention and Cross-Modal Fusion for Arabic Hateful Meme Detection

SZED submitted a system to the ArGuard 2026 Arabic hateful meme detection challenge, tackling both binary classification (A1) and fine‑grained multi‑label tagging (A2). For A1, the team fused MARBERTv2 and CLIP ViT‑L/14 embeddings using concatenation, self‑attention, and ensemble heads, achieving a macro‑F1 of 0.7597. For A2, they employed a multi‑task label‑attention architecture with per‑class query vectors and an auxiliary cascade‑calibration head, reaching a macro‑F1 of 0.3142 across ten active classes and analyzing per‑class error patterns and calibration effects.
