Classification jobs

Classification overview

The idea of classification is to assign categories to assets from a fixed set of categories.
You can classify any kind of asset: image, text, video, PDF, etc.

Let's say we have this picture to classify:

To classify our example Tesla car, you can use the following input types:

Radio button (used for single-choice classification jobs).

Check box (multiple-choice classification jobs)

Single choice Dropdown (for single-choice classification jobs with a long list of classes)

Multi choice dropdown (for multiple-choice classification jobs with a long list of classes)


  • Check which letters are shown in the category list items, next to category name. These are your category shortcuts. Use them to speed up your labeling process.
  • You can customize the category shortcuts in your project JSON file. For details, refer to Customizing project interface.

Using labeling shortcuts speeds up your work. To access the full list of labeling shortcuts:

  • Press Alt/Option + S
  • Click on the shortcut icon.

Before you start labeling, make sure that you configured your interface correctly. Refer to Customizing project interface.
