Reference documentation and code samples for the Document AI V1 API module Google::Cloud::DocumentAI::V1::DocumentSchema::EntityType::Property::OccurrenceType.
Types of occurrences of the entity type in the document. This
represents the number of instances of an entity, not number of mentions
of an entity. For example, a bank statement may only have one
account_number
, but this account number may be mentioned in several
places on the document. In this case the 'account_number' would be
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 will be set to
REQUIRED_MULTIPLE
.
