# CreateLabelingJob Creates a job that uses workers to label the data objects in your input dataset. You can use the labeled data to train machine learning models. You can select your workforce from one of three providers: + A private workforce that you create. It can include employees, contractors, and outside experts. Use a private workforce when want the data to stay within your organization or when a specific set of skills is required. + One or more vendors that you select from the AWS Marketplace. Vendors provide expertise in specific areas. + The Amazon Mechanical Turk workforce. This is the largest workforce, but it should only be used for public data or data that has been stripped of any personally identifiable information. You can also use *automated data labeling* to reduce the number of data objects that need to be labeled by a human. Automated data labeling uses *active learning* to determine if a data object can be labeled by machine or if it needs to be sent to a human worker. For more information, see [Using Automated Data Labeling](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-automated-labeling.html). The data objects to be labeled are contained in an Amazon S3 bucket. You create a *manifest file* that describes the location of each object. For more information, see [Using Input and Output Data](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-data.html). The output can be used as the manifest file for another labeling job or as training data for your machine learning models. You can use this operation to create a static labeling job or a streaming labeling job. A static labeling job stops if all data objects in the input manifest file identified in `ManifestS3Uri` have been labeled. A streaming labeling job runs perpetually until it is manually stopped, or remains idle for 10 days. You can send new data objects to an active (`InProgress`) streaming labeling job in real time. To learn how to create a static labeling job, see [Create a Labeling Job (API) ](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-create-labeling-job-api.html) in the Amazon SageMaker Developer Guide. To learn how to create a streaming labeling job, see [Create a Streaming Labeling Job](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-streaming-create-job.html). ## Request Syntax ``` { "HumanTaskConfig": { "AnnotationConsolidationConfig": { "AnnotationConsolidationLambdaArn": "string" }, "MaxConcurrentTaskCount": number, "NumberOfHumanWorkersPerDataObject": number, "PreHumanTaskLambdaArn": "string", "PublicWorkforceTaskPrice": { "AmountInUsd": { "Cents": number, "Dollars": number, "TenthFractionsOfACent": number } }, "TaskAvailabilityLifetimeInSeconds": number, "TaskDescription": "string", "TaskKeywords": [ "string" ], "TaskTimeLimitInSeconds": number, "TaskTitle": "string", "UiConfig": { "HumanTaskUiArn": "string", "UiTemplateS3Uri": "string" }, "WorkteamArn": "string" }, "InputConfig": { "DataAttributes": { "ContentClassifiers": [ "string" ] }, "DataSource": { "S3DataSource": { "ManifestS3Uri": "string" }, "SnsDataSource": { "SnsTopicArn": "string" } } }, "LabelAttributeName": "string", "LabelCategoryConfigS3Uri": "string", "LabelingJobAlgorithmsConfig": { "InitialActiveLearningModelArn": "string", "LabelingJobAlgorithmSpecificationArn": "string", "LabelingJobResourceConfig": { "VolumeKmsKeyId": "string", "VpcConfig": { "SecurityGroupIds": [ "string" ], "Subnets": [ "string" ] } } }, "LabelingJobName": "string", "OutputConfig": { "KmsKeyId": "string", "S3OutputPath": "string", "SnsTopicArn": "string" }, "RoleArn": "string", "StoppingConditions": { "MaxHumanLabeledObjectCount": number, "MaxPercentageOfInputDatasetLabeled": number }, "Tags": [ { "Key": "string", "Value": "string" } ] } ``` ## Request Parameters For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md). The request accepts the following data in JSON format. ** [HumanTaskConfig](#API_CreateLabelingJob_RequestSyntax) ** Configures the labeling task and how it is presented to workers; including, but not limited to price, keywords, and batch size (task count). Type: [HumanTaskConfig](API_HumanTaskConfig.md) object Required: Yes ** [InputConfig](#API_CreateLabelingJob_RequestSyntax) ** Input data for the labeling job, such as the Amazon S3 location of the data objects and the location of the manifest file that describes the data objects. You must specify at least one of the following: `S3DataSource` or `SnsDataSource`. + Use `SnsDataSource` to specify an SNS input topic for a streaming labeling job. If you do not specify and SNS input topic ARN, Ground Truth will create a one-time labeling job that stops after all data objects in the input manifest file have been labeled. + Use `S3DataSource` to specify an input manifest file for both streaming and one-time labeling jobs. Adding an `S3DataSource` is optional if you use `SnsDataSource` to create a streaming labeling job. If you use the Amazon Mechanical Turk workforce, your input data should not include confidential information, personal information or protected health information. Use `ContentClassifiers` to specify that your data is free of personally identifiable information and adult content. Type: [LabelingJobInputConfig](API_LabelingJobInputConfig.md) object Required: Yes ** [LabelAttributeName](#API_CreateLabelingJob_RequestSyntax) ** The attribute name to use for the label in the output manifest file. This is the key for the key/value pair formed with the label that a worker assigns to the object. The `LabelAttributeName` must meet the following requirements. + The name can't end with "-metadata". + If you are using one of the [built-in task types](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-task-types.html) or one of the following, the attribute name *must* end with "-ref". + Image semantic segmentation (`SemanticSegmentation)` and adjustment (`AdjustmentSemanticSegmentation`) labeling jobs for this task type. One exception is that verification (`VerificationSemanticSegmentation`) *must not* end with -"ref". + Video frame object detection (`VideoObjectDetection`), and adjustment and verification (`AdjustmentVideoObjectDetection`) labeling jobs for this task type. + Video frame object tracking (`VideoObjectTracking`), and adjustment and verification (`AdjustmentVideoObjectTracking`) labeling jobs for this task type. + 3D point cloud semantic segmentation (`3DPointCloudSemanticSegmentation`), and adjustment and verification (`Adjustment3DPointCloudSemanticSegmentation`) labeling jobs for this task type. + 3D point cloud object tracking (`3DPointCloudObjectTracking`), and adjustment and verification (`Adjustment3DPointCloudObjectTracking`) labeling jobs for this task type. If you are creating an adjustment or verification labeling job, you must use a *different* `LabelAttributeName` than the one used in the original labeling job. The original labeling job is the Ground Truth labeling job that produced the labels that you want verified or adjusted. To learn more about adjustment and verification labeling jobs, see [Verify and Adjust Labels](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-verification-data.html).

To learn how, see [Create a Labeling Category Configuration File for 3D Point Cloud Labeling Jobs](https://docs.aws.amazon.com/sagemaker/latest/dg/sms-point-cloud-label-category-config.html). For named entity recognition jobs, in addition to `"labels"`, you must provide worker instructions in the label category configuration file using the `"instructions"` parameter: `"instructions": {"shortInstruction":"

For all other task types, the minimum number of label categories required is one. + Each label category must be unique, you cannot specify duplicate label categories. + If you create a 3D point cloud or video frame adjustment or verification labeling job, you must include `auditLabelAttributeName` in the label category configuration.
