As a Data Annotator/QA Expert at Scale AI, I reviewed products and verified their alignment to categories in shopping websites. I compared AI responses to prompts to ensure safety, helpfulness, and factuality, and reviewed submissions from annotators providing feedback where necessary. I utilized SQL and data analysis tools to extract and manipulate data as part of the annotation process. • Verified data and product categorizations for accuracy and consistency. • Evaluated AI-generated text responses for quality, fact-checking, and adherence to guidelines. • Provided constructive quality assurance feedback to other annotators. • Used digital tools and databases to organize and review submitted data.
