To create the base of a classifier, click on the symbol. Then you can name your classifier and select a language.
After creating the classifier, the name, language, and linked reports can be seen. The report can be viewed after the first training is completed. The name and language can be edited at any time.
Once the classifier is created, it's not yet ready for use. For that to happen, it has to first be trained with data. The number of classifiers that can be created is limited.
