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 oneaccount_number, but this account number can be mentioned in several places on the document. In this case, theaccount_number is considered aREQUIRED_ONCE entity type. If, on the other hand, it's expected that a bank statement contains the status of multiple different accounts for the customers, the occurrence type is set toREQUIRED_MULTIPLE.
