Labeling Experience

AI Data Labeling Specialist

Text
In this role, I labeled and evaluated AI model outputs for quality, safety, and alignment. I ranked and scored responses based on usefulness, coherence, and factual accuracy. Quality control protocols were applied to uphold data integrity throughout the labeling process. • Labeled text-based AI outputs according to specific guidelines • Evaluated model performance and provided structured feedback • Identified and documented edge cases and safety concerns • Collaborated with researchers to refine and improve annotation instructions
