AI Data Specialist & NLP Annotation | DataEQ (Remote), Cape Town, South Africa
As an AI Data Specialist & NLP Annotation expert at DataEQ, I performed multi-label text classification, intent detection, and sentiment analysis on hundreds of social media posts weekly. I assigned structured topic taxonomy labels to train NLP and AI models, supporting clients in banking, telecoms, and retail across various projects. My work included maintaining a quality assurance accuracy rate above 95% while escalating urgent brand safety risks for timely client action. • Assigned topic taxonomy labels such as account admin, customer service, and transactions. • Conducted sentiment analysis and purchase intent identification on Twitter, Facebook, and Instagram content. • Moderated and annotated 40+ hours of social media content per week for enterprise brand intelligence systems. • Collaborated with cross-functional teams to calibrate annotation guidelines and improve labeling consistency.
