  • Sentiment Analysis:  overall sentiment of a text (Positive, Negative, Neutral, or Mixed).
  • Syntax Analysis: tagging verbs, etc.
  • Entity Recognition: returns the named entities ("People," "Places," "Locations," etc.) that are automatically categorized based on the provided text.
  • Comprehend Medical
  • Custom Entities
  • Language Detection
  • Custom Classification
  • Topic Modeling
  • Multiple Language Support
  • Medical Ontology Linkage

If you're ready to start using the Amazon Comprehend activities, see the Get Started section below. To learn more about the package, keep reading to see How it works and the Technical References.

Note: Please refer to the Product lifecycle page for UiPath Studio version compatibility and support.

How it works

To enable the outbound automation between UiPath and Amazon Comprehend, the Amazon Comprehend activities establish an authenticated connection to your AWS resources via the activity.

After your connection is established, you can add the other Amazon Comprehend activities to create new automation projects, or add them to existing projects.

How does it connect?

This is where we need your help.

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.

Technical References

Each Amazon Comprehend activity calls a Amazon Comprehend API using the request parameters you enter in the activity's input properties. If the call is successful, the activity outputs the relevant response elements (i.e., output properties) that you can use as input property values in subsequent activities, queue items in an existing Queue, and etc.

For a complete list of the Amazon Comprehend APIs used by each activity and links to the relevant API documentation, see the Technical References page. You don't need to be familiar with the Amazon Comprehend APIs to use the activities. These links are for informational purposes only in case you want to learn more about the action happening "behind-the-scenes".
