HumanTaskConfig

Information required for human workers to complete a labeling task.

AnnotationConsolidationConfig

Configures how labels are consolidated across human workers.

Type: AnnotationConsolidationConfig object

Required: Yes

MaxConcurrentTaskCount

Defines the maximum number of data objects that can be labeled by human workers at the same time. Also referred to as batch size. Each object may have more than one worker at one time.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 1000.

Required: No

NumberOfHumanWorkersPerDataObject

The number of human workers that will label an object.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 9.

Required: Yes

PreHumanTaskLambdaArn

The Amazon Resource Name (ARN) of a Lambda function that is run before a data object is sent to a human worker. Use this function to provide input to a custom labeling job.

For the built-in bounding box, image classification, semantic segmentation, and text classification task types, Amazon SageMaker Ground Truth provides the following Lambda functions:
