AI Data Annotation Specialist (Contractor/Freelance)
Labelbox
TextAs an AI Data Annotation Specialist, I have evaluated and labeled large volumes of text for AI/ML training and improvement projects. I assessed the accuracy, consistency, and factuality of AI-generated responses using structured rubrics and guidelines. My work included RLHF tasks, sentiment analysis, intent classification, and multi-criteria quality review for safety, coherence, and content alignment. • Labeled AI and human-generated text samples for classification, ranking, and fact-checking. • Performed RLHF (Reinforcement Learning from Human Feedback) tasks, ranking and rating responses per rubric. • Detected hallucinations, bias, and inconsistencies in AI outputs using detailed evaluation frameworks. • Used annotation software and platforms adaptable to Scale AI, Appen, Toloka, Remotasks, DataAnnotation.tech, and Labelbox.
