Labeling and reviewing

How to label, review, save, submit, and create issues from the Ango Hub App.

The mobile editor opens when you start labeling, start reviewing, or open a task from the task list.

At the top of the editor, you will see the project name and an info button. The asset is shown below the header, followed by the classification questions for the task.

The mobile editor shows the task asset and the classification questions below it.

Supported assets

The app can display:

• Images

• Videos

• Audio

• PDFs

• Text assets

If the task uses an asset type that cannot be displayed on mobile, the app will show a message saying that the task requires the web app.

Answering classifications

The app supports common classification tools, including radio buttons, checkboxes, dropdowns, tree dropdowns, text fields, and upload boxes.

Required questions are marked with an asterisk. If a required question is empty, the app will ask you to complete it before submitting.

If a text question has a regular expression validation rule, the app checks the answer before submission. Rich text and KaTeX text questions are shown as plain text inputs on mobile.

Saving and submitting label tasks

Tap Save to save your progress without submitting the task.

Tap Submit to submit the task. If the task still has media uploading, the app will either ask you to wait or submit the task automatically after uploads finish, depending on the project configuration.

If skipping is enabled for the project, a Skip button is shown. Skipping discards unsaved changes for the current task.

There is no autosave. If you leave a task with unsaved changes, the app will ask whether you want to discard them.

Reviewing tasks

In Review stages, the bottom action bar shows review actions.

Tap Accept to accept the task. Tap Reject to reject it.

When rejecting a task, the app checks whether there is already an open issue for the current stage. If there is no open issue, the app prompts you to create one or reject without creating an issue.

Review stages show the submitted answers and provide accept and reject actions.

Task information

Tap the info button in the editor header to open the task information sheet.

From this sheet, you can open:

• Instructions: the project's instruction PDF, when one is available.

• Issues: open and resolved issues for the task.

• Attachments: task attachments.

• Info: task metadata.

• History: stage history for the task.

The task information sheet contains instructions, issues, attachments, metadata, and task history.

Issues

From the Issues tab, tap Create Issue to create a new issue for the task.

If the project uses error codes, the app shows the available error codes when creating the issue. You can also reply to issues and resolve them from the issue list.

Issue notifications are sent through Ango Hub in the same way as issues created from the web app.
