Summary

A new annotation schema for Haitian Creole medical translation has been developed to explicitly capture clinical risk and sociolinguistic variation, designed to be lightweight for small expert teams. This schema incorporates binary fields for overall translation acceptability, the severity of potential misunderstanding, and foreign-influence cues, alongside conditional error tags aligned with Multidimensional Quality Metrics (MQM) for enhanced interoperability within the medical domain. Following three rounds of annotation and adjudication, stable inter-annotator agreement was achieved, leading to the release of a gold dataset comprising 152 English-to-Haitian Creole medical sentence pairs. A baseline classifier-labeller demonstrated that both acceptability and severity are reliably learnable even with limited data, although foreign-influence judgments were constrained by their prevalence. These findings indicate that clinically oriented, variety-sensitive annotation can support immediate screening of patient-facing translations and offer reward-ready signals for future preference-based machine translation and large language model fine-tuning.

Key takeaway

For NLP Engineers developing medical translation systems for low-resource languages like Haitian Creole, this annotation schema offers a robust framework. You should consider integrating explicit clinical risk and sociolinguistic variation fields into your quality assessment pipelines to improve patient safety and translation accuracy. This approach provides reward-ready signals for fine-tuning machine translation and large language models, even with limited data, enabling more reliable patient-facing translations.

Key insights

The annotation schema for Haitian Creole medical translation explicitly captures clinical risk and sociolinguistic variation, supporting MT/LLM fine-tuning.

Principles

• Clinically oriented annotation improves translation quality.
• Sociolinguistic variation is crucial for medical translation.
• Data scarcity doesn't preclude learning acceptability.

Method

The method involves three rounds of expert annotation and adjudication using a lightweight schema with binary fields for acceptability, severity, and foreign-influence, plus MQM-aligned error tags.

In practice

• Screen patient-facing medical translations immediately.
• Generate reward signals for MT/LLM fine-tuning.
• Develop variety-sensitive annotation for low-resource languages.
