OtherText

As a Freelance QA Evaluator and Data Annotator, I reviewed AI-generated text responses for quality, safety, and accuracy. My main task was rating and refining responses in UK English to ensure they were helpful, unbiased, and culturally appropriate. I consistently met high standards, maintaining a score of 98% or higher in qualification tests. • Evaluated content for grammatical correctness and natural UK English expression. • Rated responses for helpfulness, truthfulness, and bias. • Provided edits to improve machine learning outputs. • Used multiple annotation platforms and software tools.
