Overview of the Text data annotation tool in Ango Hub

The text labeling tool allows you to ask labelers open-ended questions.

How to add a Text tool to your project

From the project’s Settings tab, enter the Label Set section.

Click on Add Category. From the list that appears, click on Text.

A new row will appear named Text. Click on it to expand it.

Text Tool Options

Schema ID: The unique ID assigned to the tool.

Title: The name of your labeling tool.

Required: If you enable this toggle, labelers will be required to answer this field before saving.

Regex Validation: If you enter a regular expression in this field (without the initial and final \ slashes), labelers' answers to this field will have to match the regex being input before saving.

Rich Text Editor: If enabled, the user will not see a plain text field, they will instead see a rich text editor where they can make text bold, italic, add images, and more. This is then stored and served in the export as HTML.

KaTeX Preview: If enabled, you may have annotators see a live preview of KaTeX, a mathematical subset of LaTeX:

Frame-specific: If you enable this toggle, the answer to this classification will only be valid for one frame (in videos and multi-frame images/DICOMs) instead of the whole asset.

Multiple: If enabled, annotators can answer this classification multiple times.

Once you have selected your options, click on Save at the bottom to save your changes.
