AI Data Labeling Contributor – Text Classification
I executed text classification tasks for sentiment analysis, intent tagging, spam detection, and content quality rating as part of NLP training pipelines. Each task required careful application of annotation rules and consistent judgment per project standards. My work supported ongoing improvement of AI natural language understanding. • Labeled text for sentiment, intent, and spam categories • Classified messaging content quality for NLP training datasets • Applied annotation guidelines for consistent judgment across samples • Maintained above-threshold accuracy and advanced tier status
