Data Annotation and Evaluation

LabelboxTextRed Teaming

I evaluated, reviewed, and verified product alignment and categories across several websites. I provided structured feedback to annotators and compared AI responses to prompts for safety and factual accuracy. My work aimed to support algorithm improvement for recommendation and search engine quality. • Evaluated and refined over 200 prompts for accuracy and usefulness. • Performed more than 100 data annotation tasks and gave feedback to other annotators. • Conducted pairwise comparisons of search engine outputs for improved relevance. • Focused on fact-checking and safety responses in AI outputs.
