Researchers have developed a novel two-stage model for detecting harmful content in Arabic, addressing challenges posed by dialectal variations and semantic overlap. The system first utilizes GLiNER to identify harm-related entities within user prompts. These extracted entities are then appended to the original text and processed by a fine-tuned MARBERT classifier for final classification, achieving a macro-F1 score of 0.886 on the ArGuard 2026 development set. The approach demonstrates the effectiveness of integrating Named Entity Recognition (NER) with Arabic language models for fine-grained harmful content detection, though distinguishing between closely related harm categories remains an area for improvement.
