startKeyPhrasesDetectionJob method

Future<StartKeyPhrasesDetectionJobResponse> startKeyPhrasesDetectionJob({ required String dataAccessRoleArn, required InputDataConfig inputDataConfig, required LanguageCode languageCode, required OutputDataConfig outputDataConfig, String? clientRequestToken, String? jobName, String? volumeKmsKeyId, VpcConfig? vpcConfig, })

Starts an asynchronous key phrase detection job for a collection of documents. Use the operation to track the status of a job.

May throw InvalidRequestException. May throw TooManyRequestsException. May throw KmsKeyValidationException. May throw InternalServerException.

Parameter dataAccessRoleArn : The Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that grants Amazon Comprehend read access to your input data. For more information, see https://docs.aws.amazon.com/comprehend/latest/dg/access-control-managing-permissions.html#auth-role-permissions.

Parameter inputDataConfig : Specifies the format and location of the input data for the job.

Parameter languageCode : The language of the input documents. You can specify any of the primary languages supported by Amazon Comprehend. All documents must be in the same language.

Parameter outputDataConfig : Specifies where to send the output files.

Parameter clientRequestToken : A unique identifier for the request. If you don't set the client request token, Amazon Comprehend generates one.

Parameter jobName : The identifier of the job.

Parameter volumeKmsKeyId : ID for the AWS Key Management Service (KMS) key that Amazon Comprehend uses to encrypt data on the storage volume attached to the ML compute instance(s) that process the analysis job. The VolumeKmsKeyId can be either of the following formats:

• KMS Key ID: "1234abcd-12ab-34cd-56ef-1234567890ab"
• Amazon Resource Name (ARN) of a KMS Key: "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab"

Parameter vpcConfig : Configuration parameters for an optional private Virtual Private Cloud (VPC) containing the resources you are using for your key phrases detection job. For more information, see Amazon VPC.
