**Comprehend Moderation** is used to detect and handle `Personally Identifiable Information (PII)`,
|
|
`toxicity`, and `prompt safety` in text.
|
|
|
|
The Langchain experimental package includes the **AmazonComprehendModerationChain** class
|
|
for the comprehend moderation tasks. It is based on `Amazon Comprehend` service.
|
|
This class can be configured with specific moderation settings like PII labels, redaction,
|
|
toxicity thresholds, and prompt safety thresholds.
|
|
|
|
See more at https://aws.amazon.com/comprehend/
|
|
|
|
`Amazon Comprehend` service is used by several other classes:
|
|
- **ComprehendToxicity** class is used to check the toxicity of text prompts using
|
|
`AWS Comprehend service` and take actions based on the configuration
|
|
- **ComprehendPromptSafety** class is used to validate the safety of given prompt
|
|
text, raising an error if unsafe content is detected based on the specified threshold
|
|
- **ComprehendPII** class is designed to handle
|
|
`Personally Identifiable Information (PII)` moderation tasks,
|
|
detecting and managing PII entities in text inputs
