Dataset status

This is a research checkpoint trained from machine annotations. Rows are not human-gold labels. The main medical source is CC-BY-NC-4.0, so use is non-commercial research unless separate permission is obtained.

Source notes

• Ghana Health Symptoms rows are the primary medical semantic-recovery source.
• WAXAL rows are included only as language-coverage silver rows after filtering.
• GhanaNLP speech-text rows are included as local language-coverage silver rows; they are described in the card body, not HF front-matter, until the source id and license are audited.
