Establishing Connection with Amazon Comprehend

To establish outbound automation between UiPath and Amazon Comprehend, the Amazon Comprehend activities facilitate an authenticated connection to your AWS resources through their associated activities. Once the connection is established, you can integrate these activities into new automation projects or add them to existing ones.

Setting Up AWS IAM Authorization

To establish an authenticated connection, the Amazon Textract activities need authorization from the AWS Identity and Access Management (IAM) service.

To enable AWS IAM authorization, you create or use an existing IAM user and generate access keys (Access Key Id and Secret Access Key). When creating your IAM user, you assign the policies and permissions that specify the resources your Robot can access (e.g., AmazonTextractFullAccess).

After creating your IAM user and assigning your policies, you enter the Access Key Id and Secret Access Key in the Amazon Scope activity. When you run your automation project, the keys are used to sign the API requests being made by each of the activities.

Activities in the Amazon Comprehend Activities Package

The activities included in the Amazon Comprehend Activities Package are:

Amazon Comprehend Scope

Establishes an authenticated connection between UiPath and your AWS resources using IAM credentials.

Invoke Method

The Invoke Method activity allows you to specify any public Amazon Comprehend API operation and its relevant properties.

Infer ICD10CM

The Infer ICD10CM activity allows you to infer ICD10CM information from a text string. After completing the operation, the activity outputs the result of the operation in an Entities record.

Infer RxNorm

The Infer RxNorm activity allows you to infer RxNorm information from a text string. After completing the operation, the activity outputs the result of the operation in an Entities record.

Medical Entities Analysis

The Infer Medical Entities Analysis activity allows you to specify any of the public Amazon Comprehend Medical API Medical Entities Analysis operations and its relevant properties. After invoking the operation, the activity outputs the any properties that you have set as variables and the status of the request (success/failure information) in a ResponseStatus object that you can use in subsequent activities (e.g., conditional logic).

PHI Analysis

The Infer PHI Analysis activity allows you to specify any of the public Amazon Comprehend Medical API PHI Analysisoperations and its relevant properties. After invoking the operation, the activity outputs the any properties that you have set as variables and the status of the request (success/failure information) in a ResponseStatus object that you can use in subsequent activities (e.g., conditional logic).
