Labeling Experience

Data Tagging Analyst

DocumentClassification
As a Data Tagging Analyst at Digital Analytics Corp, I managed multiple labeling projects to maximize data ROI. My labeling processes achieved a consistent 95% data precision rate, validated through methodological checks and audits. I ensured standardization and compliance across all tagging teams. • Oversaw document-level data labeling projects across divisions. • Standardized workflows and procedures for data taggers. • Performed detailed audits for consistency and quality. • Leveraged internal/proprietary software to meet project goals.
