OccurrenceType

OccurrenceType(value)

Types of occurrences of the entity type in the document. This represents the number of instances 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.

Values: OCCURRENCE_TYPE_UNSPECIFIED (0): Unspecified occurrence type. OPTIONAL_ONCE (1): There will be zero or one instance of this entity type. The same entity instance may be mentioned multiple times. OPTIONAL_MULTIPLE (2): The entity type will appear zero or multiple times. REQUIRED_ONCE (3): The entity type will only appear exactly once. The same entity instance may be mentioned multiple times. REQUIRED_MULTIPLE (4): The entity type will appear once or more times.
