How to create a hierarchy for the labels. Can you please mention the steps for creating a hierarchy for the labels.
How you set up your label scheme depends on your specific problem. Ultimately, it's up to you how you set up the hierarchies and how you annotate them. You'd typically start at the top with the most general labels and assign them. And then for each assigned label, you can go over the examples with that label again and assign lower-level categories - for instance, using a multiple choice interface.
