Single Relation

Overview of the Single Relation relational data classification tool in Ango Hub

The Single Relation labeling tool allows you to create a relation between two annotations.

How to add a Single Relation 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 Single Relation.

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

Give your single relation tool a title and description.

Enable the Required toggle if you want to force labelers to create a single relation for each asset. When the toggle is disabled, labelers will be able to save and move to the next asset without creating the single relation.

How to Draw a Single Relation

Click on the label where you’d like the single relation to start. Click on the second label where you’d like the relation to end.

Differences between Single Relation and Tables

Single Relations are ideal in situations where there is a relatively small number of relations in an asset. This is because after a certain number of single relations have been created, the number of arrows can make it hard to perform further labeling.

For assets with a large number of relations, we recommend using the Tables tool.
