Reference documentation and code samples for the Document AI V1beta3 API module Google::Cloud::DocumentAI::V1beta3::DocumentSchema::EntityType::Property::OccurrenceType.
Types of occurrences of the entity type in the document. This
represents the number of instances, not mentions, of an entity.
For example, a bank statement might only have one
account_number, but this account number can be mentioned in several
places on the document. In this case, the account_number is
considered a REQUIRED_ONCE entity type. If, on the other hand, we
expect a bank statement to contain the status of multiple different
accounts for the customers, the occurrence type is set to
REQUIRED_MULTIPLE.
