Document classification is when you need to say something about an entire document, as opposed to certain words in it. Document classification comes in two flavors, single class classification and multi-class classification.
Whether you are in single or multi class mode is configured by the project manager.
Single class, as the name implies, is when you need to choose exactly one class

Multi Class mode, you can select more than one class

Working With Many Classes
In some jobs, you may have tens or even hundreds of classes to choose from, such as with large sets of intents for chat bots or document routing for support.
LightTag makes such cases easy by allowing you to search through the classes
