Text
I performed text tagging, script evaluation, and some picture and video labeling to generate datasets for AI model training. My responsibilities included following strict annotation guidelines to ensure consistent, accurate labels and collaborating remotely with other contributors on distributed AI training projects. I maintained a high level of accuracy in text, picture, and video tagging while processing large dataset volumes. • Labeled data included text, images, and videos for various machine learning objectives. • Ensured over 85% accuracy through quality control measures. • Used proprietary/internal software platforms for annotation tasks. • Supported AI teams through feedback and high-quality data contribution.
