Configure an Elements campaign

You can create Elements campaigns in order to draw and create new elements of given types on your documents.

Configuration parameters

After having filled out the generic configuration parameters, you need to select the element types that will be available for element creation.

Available types are retrieved from the object your Callico project is linked to on its external provider. If your campaign's Callico project is linked to an Arkindex project, the available types to select from are all the element types available on that Arkindex project.

Correction of imported elements

If the purpose of your campaign is to correct existing imported elements then you need to select the imported element types. Only the child elements for which the corresponding type has been checked in the campaign configuration will be available to be corrected by the contributors: the annotation task will be pre-filled with drawn elements on the image.

Example annotation task

If the campaign is configured as above, to use text line and text zone as the available element types, then for the contributors the tasks will look like the example below: they can select one of the element types, and then draw elements on the image.

Polygon borders

In the screenshot above, you can see thin borders in a darker shade of green than the drawn polygons. These borders surround the polygons and will therefore not be exported at the same time as the drawn elements.

To prevent your contributors from drawing polygons that will be too small, you can specify this information in your campaign instructions.

Once your campaign is configured, you can create tasks to start gathering annotations on your documents.
