Labeling Experience

Text Sentiment Labeling Project Contributor

OtherTextClassification

For a text classification project, I performed manual sentiment labeling on datasets used for AI training. My efforts focused on improving dataset quality and ensuring reliable sentiment representation. I also provided feedback and flagged inconsistencies for revision. • Conducted manual review sessions to validate text labels • Ensured detail-oriented sentiment annotation following guidelines • Enhanced classification accuracy for subsequent training rounds • Coordinated with team leads to resolve label ambiguities
