. For image data, labelers may apply bounding boxes, polygons, or semantic segmentation to identify objects or regions of interest3
. Text data might be labeled using natural language processing techniques or named entity recognition, while audio data could involve transcription or keyword spotting3
. The labeled data is then used to train machine learning models, enabling them to recognize patterns and make predictions on new, unseen data1

. Quality control measures, such as consensus pipelines and manual auditing, are often implemented to ensure accuracy and consistency in the labeling process3
. As datasets grow larger, automated and semi-automated labeling techniques are increasingly employed to improve efficiency and scalability4
