Amazon Comprehend is a natural language processing (NLP) service that uses machine learning to discover insights and relationships in text. Starting today, you can assign tags to custom classifier and entity type resources. This enables you to allocate costs and get detailed billing reports across your custom models.

Each tag is a simple label consisting of a customer-defined key and an optional value that can make it easier to manage, search for, and filter resources. You can allocate costs by creating tagged Billing Groups and mapping individual “Things” to those groups.

All usage and cost for a model will inherit the tags of the Billing Group to which it belongs. IAM policies also support tag-based conditions, enabling you to constrain IAM permissions based on specific tags or tag values (when leveraging tag-based conditions for access control, make sure to also define and restrict who can modify those tags).

These features are provided at no additional cost. Click here to learn more about how to create and use tags in Amazon Comprehend. See AWS Tagging Strategies for general best practices for using tags with AWS resources.
