What is AI Data Labeling?

AI Data Labeling (or Data Annotation) is the process of attaching precise, descriptive metadata to raw datasets—such as bounding boxes on images or sentiment tags on text. This labeled 'ground truth' allows machine learning and generative AI algorithms to accurately recognize patterns, comprehend context, and generate high-quality outputs.
