Data Labeling Platforms Comparison

Data labeling is a hot topic as a recent report from AI research and advisory firm Cognilytica found that over 80% of the time enterprises spend on AI projects goes toward preparing, cleaning and labeling data.

A new category of tools has emerged, called data labeling platforms, training data management platforms. Three years ago, this market did not exist. Today, the offer is plentiful and it is sometimes complicated to find one's way.

A good annotation tool must meet three needs:

• annotate quickly (productivity of annotators)
• annotate well (control the quality / consistency of annotations)
• annotate the right data (source diversity in the dataset)

Here is an attempt to do a fair comparison of data labeling / training data platforms.

I tried to be as accurate as possible, based on my experience with those solutions and their documentation. If you see any mistake (this is likely), please create an issue / push a PR.
