Intelligent and fast parsing of Australian addresses
A common problem when dealing with Australian addresses is that they are often recorded as strings as they appear on an envelope. For example,
1408/170 The Esplanade St Kilda VIC 3182
In order to match with data, such as the PSMA, we often want to
extract the components of this address. For example, we want to extract
the flat number (1408) and the postcode (3182). Problems arise in both
performance and intelligently parsing this address. In the above, we
want to recognize that ‘St’ refers to ‘Saint Kilda’ not ‘Street’. The
package healthyAddress attempts to provide fast and
intelligent parsing of Australian addresses.
The main function is standardize_address:
library(healthyAddress)
standardize_address("1408/170 The Esplanade St Kilda VIC 3182")
#> FLAT_NUMBER NUMBER_FIRST NUMBER_LAST NUMBER_SUFFIX STREET_NAME
#> <int> <int> <int> <raw> <char>
#> 1: 1408 170 0 00 THE ESPLANADE
#> STREET_TYPE_CODE POSTCODE STREET_TYPE
#> <int> <int> <char>
#> 1: 0 3182 <NA>Created on 2024-01-31 by the reprex package (v2.0.1)
There are two arguments to the function that affect performance,
hash_StreetName: instead of returning the street name
as a string, return an integer. This can be useful when performing
merges (which are faster on integer vectors), by applying
HashStreetName to the foreign table’s street name.integer_StreetType: instead of returning the street
type as a string, return an integer.check performs a check on the input. Setting to zero
can improve performance on input that has already checked.
