Synonym

The synonym takes a data element and keeps it, but assigns it the same meaning as another entry in the definitions table. Example: ‘Maria’ Synonym=’Mary’. In this example, the Parser treats Maria and Mary as the same data.

Level2-Switch

This is an aliasing feature which tries out a different Level 2 value to account for situations where locality districts are assigned to different city/county jurisdictions, or cases where some (but not all) Level 3 values are reassigned to a different Level 2. By entering in a Level2-Switch value, the Postal Matcher can try the alternative and perform a check against the GAV tables. If the alternate results in a match, then a recode is performed on the data.

Syntax

‘Input L2’ Level2-Switch Rec=’Alternate L2’

Example

Level4-Alias

This is another aliasing feature which looks for prefix aliases.

Syntax

‘Alias Prefix’ Level4-Alias Rec=’Valid L4 Prefix (1), Valid L4 Prefix (2), up to 10’

• For more than ten, enter on separate line(s).
• Use only prefix. The other half is listed in the Level4-Endings list.
• For an L4 Alias (variation) in the input record, the Postal Matcher scans through all of the possible prefixes in combination with the valid endings and performs a lookup within the possibilities within an L3 (including all L3 #s).

Example

Level-Recode

This is a special recode that allows specifically targeted geographic recodes to compensate for spelling errors and bad geographic levels. Note that the Level-Recode is used in conjunction with the standard RECODE keyword.

Syntax

[level1,level2,level3,level4,low_num,high_num,postcode] Level-recode REC=[new_l1,new_l2,new_l3,new_l4,new_low_num, new_high_num,new_postcode]

where,

the "left side" of the equation = input geographic combination

the "right side" of the equation = desired output geographic combination

Example 1

In this example, misspelled Level 3 is corrected.

Example 2

In this example, Level 3 is recoded for specified block number range only.

Example 3

In this example, the old L2-L4 combination is updated with the new L2-L3 combination with a new postcode.

Example 4

In this example, the block number range is modified.

Example 5

You can combine the level recode with automated L3 number check.

Bad example:

This example looks for input data that comes in exactly with the L1,2,3,4 combination in order to do a recode. This is a very limited implementation and should be avoided if possible.

Good example:

In this example, regardless of how the Level 3 appears in the input dataset (도곡동, 도곡1동 etc.) the 타워팰리스 is recoded to 삼성타워팰리스, and the L3 number is correctly referenced and recoded to 도곡2동.
