2. Batch
A batch is the result of splitting a complete task and is also the minimum unit of productivity process.
3. Item
Item is each corresponding image/point cloud/text/video/questionnaire, etc. in the batch, and is also the smallest data unit that a labeler can get.
4. Frame
Frame is a concept that appears in continuous frame tasks, where an item can contain n frames of images/point clouds.&##x20;
