Description
This is a NER model trained using custom finance embeddings which allows you to detect some generic entities that may require to be masked or obfuscated to be compliant with different regulations, as GDPR and CCPA. This is just an NER model, make sure you try the full De-identification pipelines available in Models Hub.
Predicted Entities
AGE, CITY, COUNTRY, DATE, EMAIL, LOCATION-OTHER, FAX, ORG, PERSON, PHONE, PROFESSION, STATE, STREET, URL, ZIP
