Setting up your labeling project's ontology on Ango Hub
Last updated
A project’s category schema (also known as ontology) is the list of labeling tools available in the project.
Ango Hub allows project owners to set the project’s ontology directly from the Category Schema section of the Settings page.
The ontology created from this section is then reflected in the left sidebar of the labeling editor:
From the project’s Settings tab, enter the Label Set section.
Click on the Add Category button and choose the labeling tool to add. Each tool has a slightly different setup process. See here for a list of all labeling tools available in Ango Hub, and how to add them to your project.
For a guide on how to create nested classifications, see here.
Please check this guide.
From the Settings tab, in the Category Schema section, click on the "History" icon on the top-right to open a history of all workflow versions in the current project.
Category Schema history started being recorded on March 12, 2025. Versions before then had not been saved.
To view a previous version of this project's ontology, click on Preview. To restore it, click on Save while the version you need is previewed.
