10 Best Data Labeling Tools and Software

Data labeling involves assigning tags or labels to unprocessed data like text, images, videos, or audio.

These labels represent the category or class to which the data belongs and aid in training a machine learning algorithm to identify objects of that particular class in unlabeled data.

Data labeling tools are software programs that leverage artificial intelligence (AI) and machine learning (ML) algorithms to automate the process of labeling large datasets. These tools can reduce the time and cost required for human annotation, while also improving the accuracy of the labeling process.
