S-Chain: Structured Visual Chain-of-Thought for Multilingual Medicine

S-Chain is a multimodal medical dataset developed by Khai Le-Duc and a multi-institutional research team, last updated in December 2025. It provides structured visual chain-of-thought reasoning paths for clinical tasks across eight languages, including English, Arabic, and Japanese. The data supports a wide range of tasks from object detection to multilingual text generation.

Use Cases

• Visual Question Answering (VQA) using medical images and reasoning chains
• Zero-shot object detection for clinical feature identification
• Multilingual medical text generation in languages like Korean and French

Strengths

• Multilingual support across 8 distinct languages
• Multimodal coverage including object detection and VQA
• Structured reasoning format for medical logic

Limitations

• Unknown total record count
• Potential complexity in evaluating structured chain-of-thought outputs
