Text

Overview of the Text tool in Ango Hub

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

The Text tools are supported across the Audio, Image, Video, DICOM, Medical, PDF, Text, LLM, and Markdown labeling editors.

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.

Labelers answer in a plain text box. This box grows automatically as the labeler types longer answers, up to about 10 visible rows. After that, the field remains scrollable, and labelers can still resize it vertically.

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.
