Bangla case study integrates SLMs with culturally-sensitive NLP for health misinformation detection

This research proposes a culturally and linguistically diverse (CALD) friendly AI-based detector for health misinformation, specifically addressing the lack of effective tools for low-resource languages like Bangla. The authors evaluate Small Language Models (SLMs) to overcome the limitations of Large Language Models in this context.

• Experiments were conducted using a Bangla-translated health misinformation dataset to assess various SLMs.
• Phi-4 emerged as the superior model, achieving an ideal balance between precision and recall in claim extraction.
• A novel detection framework was designed based on Responsible NLP, incorporating cultural sensitivity, potential for harm, and communication quality.

The study provides a dashboard for medical professionals to analyze misinformation, offering a holistic lens for evaluation in low-resource linguistic contexts.
