This experience involved annotating video datasets for AI training projects by following detailed guidelines. I applied both dense and coarse labeling methods and segmented video data into distinct action units using timestamps. Consistency checks and error corrections were integral to maintaining high data quality. • Annotated episodic video data with specific verb-object labels • Used strict timestamp rules for precise action segmentation • Maintained object naming and action sequence consistency across the dataset • Reviewed annotations for quality assurance and audit standards
