Example 4: Calling an external service/framework for PII detection

In a similar way to example 3, we can write logic to call external services for PII detection. There are two types of external services we support:

1. Remote services such as a PII detection model hosted somewhere. In this case, the recognizer would do the actual REST request and translate the results to a list of RecognizerResult.
2. Calling PII models from other frameworks, such as transformers or Flair.

Calling a remote service

1. Documentation on remote recognizers.

2. A sample implementation of a remote recognizer.

Calling a model in a different framework

• This example shows a Presidio wrapper for a Flair model.
• Using a similar approach, we could create wrappers for HuggingFace models, Conditional Random Fields or any other framework.
