Segmentation
ClassificationSupported AI training multi-modal data processing for audio, video, and text datasets, performing cleaning, segmentation, and quality assurance before downstream use. Ensured data integrity by removing corrupted data, standardizing formats, and maintaining traceable processing through structured workflows. Performed baseline text semantics labeling and content safety screening aligned with large-model data governance requirements. • Process and prepare large volumes of raw multi-modal training materials using established pipelines. • Carry out audio denoising, video slicing, text cleaning, and standardized quality checks. • Conduct semantic tasks such as intent classification, entity extraction, and QA matching validation. • Screen and categorize ambiguous and policy-risk text content for safety and consistency.
