Item Attributes

Overview

Item Attributes allow users to add extra information about a file or group of files using custom fields. These fields aren't connected to specific region of a file (like properties), but instead apply to the whole file. For example, you might ask, "Would you recall a patient based on these exams?" This could mean looking at multiple files, like a mammogram and an MRI, to make a decision. You can also make some questions required, which means users can't move forward without giving an answer.

Creating Item-Level Attributes

Go to the Classes Page: Find the Classes page and choose either single-select or multi-select from the Item Attributes menu.
Set Up the Attribute:
- Name the Attribute and click "Set Up Class".
- Write the Question: Type the question or prompt that you want your labelers to see.
- Give Possible Answers: List the answers labelers can choose from. Note: Labelers can't add new answers while labeling.
- Choose If It's Required: If you make it required, labelers must answer before they can move on.
- Click Save Changes.

Using Item-Level Attributes

After creating an attribute, add it to your dataset. The attributes will automatically show up in the annotation panel on the left when a labeler opens the file. This means they don’t have to be added manually to each file, like polygons or bounding boxes.

Example Use Case

Question: "Did this video capture a safety incident?"

Possible Answers: "Yes, a safety incident occurred" or "No, no incident observed."
Required: Yes, so labelers can't continue without answering.

This setup helps reviewers say if a big event, like a safety incident, happened in the video. It's especially useful when reviewing lots of footage to find important events.

Benefits

Consistency: Makes sure data is collected the same way for all files.
Better Decisions: Gathers important information that helps make decisions beyond specific regions in a file.
Easy to Use: Attributes show up automatically in the labeling panel, making it faster to work with.

Future Enhancements

Future updates will include:

Text Fields: Letting users add notes or instructions specific to a file, like the patient’s age, scan date, or special instructions.
Filtering and Logic Stages: Letting users sort files based on their answers and set up workflows based on these properties.
Stage-Specific Classes: Allowing different questions or requirements at different stages of a project, giving more control over complex review processes.

These updates will make Item Attributes even more useful for organizing tasks and handling detailed reviews.
