Labeling Experience

Freelance AI Data Specialist

LabelboxText

I led projects focusing on annotating and labeling data in text, audio, image, and video formats to train and refine machine learning models. I compared AI-generated responses with human intent to ensure that models understood context, accuracy, and tone. I followed detailed annotation guidelines to maintain high standards of precision across all deliverables. • Analyzed and tagged complex language data for conversational AI and other NLP models. • Evaluated the contextual quality of AI outputs and performed reference parameter comparisons. • Removed errors, identified omissions, and provided feedback to improve model alignment with human capabilities. • Used both manual and platform-based tools to ensure adaptability and compliance.
