Yes, I have experience in AI training and data labeling, including text classification, sentiment analysis, data categorization, content evaluation, and guideline-based annotation. I have performed quality assurance reviews, validated labeled datasets, identified inconsistencies, and ensured compliance with annotation standards to support the development of accurate and reliable AI models. I am also skilled at identifying AI-generated text by analyzing linguistic patterns, repetition, coherence, tone consistency, hallucinations, and other indicators commonly associated with machine-generated content. My experience includes evaluating content quality, detecting synthetic or AI-assisted writing, and distinguishing it from human-written text for moderation, quality control, and training purposes. Additionally, I have contributed to improving annotation quality by documenting edge cases, resolving labeling discrepancies, and providing feedback on guidelines to enhance model performance and dataset accuracy.
