Labeling Experience

Human Labeling Analyst - OpenTrain

TextBounding BoxPolygon

You perform human verification and correction of corporate attributes for AI dataset creation using text-first OSINT and official registries. You structure, clean, and map complex records in Microsoft Excel to maintain high accuracy and data completeness. Your work requires strong analytical reasoning, attention to detail, and the ability to operate independently in a high-volume remote workflow. • Verified and cross-referenced corporate details such as jurisdiction, directors, revenue ranges, and legal entities. • Cleaned and structured complex records in Microsoft Excel to meet 100% human-verification standards. • Applied business-structure knowledge to create high-context tags for entity profiling tasks. • Followed asynchronous production processes while ensuring accuracy for critical data fields.
