Object/entity relation jobs

Object/entity relation overview

When you're done with your Object/entity detection jobs, you can create an additional job in your project that will handle relations between labeled objects/entities.

Depending on the asset type selected for your project, you can annotate relations between objects and/or named entities:

Relations can be:

  • one to one
  • one to many

Using labeling shortcuts speeds up your work. To access the full list of labeling shortcuts:

  • Press Alt/Option + S
  • Click on the shortcut icon.

Before you start labeling, make sure that you configured your interface correctly. Refer to Customizing project interface.

📘

For relation labeling to work properly, you must configure at least one relation.

For example, in Albert Einstein's bio, we want to mark the relation between his surname, first name, nationality(ies), and occupation.

We start off with a labeled text:

Then, from the list on the right-hand side of the screen, we select the type of relation. In our case, "Person" (when you click, only the start entity will be visible; all other types will be hidden).

Click on the start object/entity. In our case, on one instance of the word "Einstein".
This is a one-to-many relation between a person's surname and: first name, nationality(ies), and occupation, so all the irrelevant classes are hidden.

Now, we need to click on the destination entities.

📘

To quickly modify the class of an entity, without losing the related relations, you can just click on the entity, and select the new token to identify it. The relation will be updated accordingly.
