# Reviewing Projects

## Overview

Reviewer mode helps you review labeling work and ensure data quality. As a reviewer, you check accuracy, resolve conflicts, and keep the workflow consistent.

## How it works?

You must have the **Reviewer** role to use the reviewer mode in a project. [Learn more about roles here](/workspace-management/role-and-permission.md).

### Reviewer mode for span labeling

In span labeling projects, there are three types of conflicts:

* Content conflict
* Span conflict
* Arrow conflict

See the [documentation](/advanced/extensions/review.md#conflicts) for details on the differences between these conflict types.

#### Resolve conflicts

To resolve a conflict, right-click the conflicted label to accept or reject it. You can also replace it by left-clicking the label and selecting a new one.

#### Navigate between conflicts

You can navigate between conflicts from the **Go** menu or by pressing `Alt` + `Shift` + `Right` to go to the next conflict and `Alt` + `Shift` + `Left` to go to the previous one.

#### Label status colors

In reviewer mode, label colors indicate the status of each label. You can view the color legend in the status bar at the bottom.

* **Gray** labels mean they have reached consensus among labelers.

* **Yellow** labels indicate that they were created using the [asisted labeling extensions](/assisted-labeling/ml-assisted-labeling.md).

  <figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-2cfbfc178f01d0425a64291d2ef757a7aa0349a2%2FProject%20-%20span%20labeling%20-%20reviewer%20mode%20-%20hover%20on%20suggested%20label.png?alt=media" alt=""><figcaption></figcaption></figure>
* **Blue** labels mean the label has been rejected by the reviewer. By default, rejected labels are hidden. You can make them visible in **File** → **Settings** → **Administration** by enabling **Show rejected labels in reviewer mode**.

  <figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-2d04c25437bd1e957f38a7b6a276281296e1ba5c%2FProject%20-%20span%20labeling%20-%20reviewer%20mode%20-%20hover%20on%20rejected%20label.png?alt=media" alt=""><figcaption></figcaption></figure>
* **Purple** labels indicate that they were applied by the reviewer.

* **Red** labels indicate that they are conflicted (have not reached the consensus threshold) and require review to be accepted or rejected.

  <figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-29b36c2f1b2aa4cf51f8ada4d89e84725171ccf2%2FProject%20-%20span%20labeling%20-%20reviewer%20mode%20-%20hover%20on%20conflicted%20label.png?alt=media" alt=""><figcaption></figcaption></figure>

In span labeling, you can see the number of applied labels, the last labeled row, and the total resolved rows. This information is shown in the bottom-right corner.

<figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-475046de16b029e033deeec3a3110c6c4af46dd7%2FProject%20-%20span%20labeling%20-%20status%20bar%20-%20reviewer%20mode%20-%20highlight%20labeling%20metrics.png?alt=media" alt=""><figcaption></figcaption></figure>

### Reviewer mode for row labeling

Reviewing in row labeling focuses on accepting, rejecting, or updating answers in each row using the **Row labeling** extension.

<figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-5fac49b8e5b0951d07153d999bb010f56e5d5ba9%2FProject%20-%20row%20labeling%20-%20reviewer%20mode%20-%20row%20labeling%20extension.png?alt=media" alt=""><figcaption></figcaption></figure>

#### Row colors

Each row has a colored line on the left side of the number column to indicate its status.

<figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-e1e4811ae2397b5b77c59e3d56e3ed7b6bc3bac8%2FProject%20-%20row%20labeling%20-%20reviewer%20mode%20-%20line%20colors.png?alt=media" alt=""><figcaption></figcaption></figure>

* **No colored line** means the answers for that row have reached consensus among labelers or have already been resolved by the reviewer.
* **A red line** indicates that the row has no consensus. All answers are conflicted.
* **A pink line** indicates that the row contains both a consensus answer and a conflicting answer. This occurs when a question allows multiple answers.

  <figure><img src="https://448889121-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MbjY0HseEqu7LtYAt4d%2Fuploads%2Fgit-blob-4a19341828e1a0925986d1ee9b5ee0401cc164ba%2FExtension%20-%20row%20labeling%20-%20multiple%20answers%20-%20partially%20conflicted.png?alt=media" alt=""><figcaption></figcaption></figure>

#### Answers in the table

Whether answers are shown in the table depends on their status.

* **Meets consensus:** Answers are displayed.
* **Conflicted (No consensus):** No answers are displayed.
* **Mixed consensus and conflict:** Only consensus answers are shown; conflicted answers appear after review.
* **Resolved by reviewer:** Final answers are displayed after review.

Submitting answers in the **Row labeling** extension updates the table accordingly.

### Reviewer mode for document labeling

The behavior is similar to row labeling, with the main interactions happening in the **Document labeling** extension.

### Reviewer mode for bounding box labeling

Review for bounding box labeling is not yet available. This feature is coming soon!
