Labeling Experience

Freelance AI Content Evaluator (Text Evaluation)

Scale AIText

As a Freelance AI Content Evaluator, I categorized text and evaluated AI-generated answers against rubric criteria. Tasks included tagging sentences by meaning and determining which of two AI responses was more appropriate and understandable. Rigorous quality assurance and structured feedback ensured high-quality labeled datasets for NLP model development. • Classified sentences and text data for semantic understanding tasks. • Compared AI-generated responses, rating answer quality for prompt alignment. • Conducted structured data cleaning to remove irrelevant or erroneous entries. • Worked remotely using the Scale AI labeling platform.
