N3SCE – Year Matching

The N3SCE method compares two years. The input field is expected to only contain a year in the form YY or CCYY. The routine ignores the

REFxx

options as there is not enough structure to support them.

Of the local options, it supports

RANGE*nnn

similar to N3SCD but the range specifies years, not days.

This method supports the following local options:

LOPT=(RANGE*[ number ]): If the years are
[number]
years apart or less, then score 100. If they are less than twice
[number]
years apart, then score 50. Otherwise, score 0.
[number]
can be in the range 0 to 32767.
LOPT=(EXTDRNGE+RANGE*[number]): Allows a gradual degradation of the score that SSA-NAME3 returns from the range value specified in
RANGE
. If the difference between the years is more than the range specified, the score is 0. Otherwise, SSA-NAME3 uses the following method to calculate the score:
Score = 100 - (difference between two dates * 100 / range); For example, the range difference between
2014
and
2020
is
6
, and the
[number]
is
10
. SSA-NAME3 uses the following method to calculate the score:
Score = 100 - (6 * 100/10) = 100 - 60 = 040; This option has no effect if you don't specify the
RANGE
value.

The following option controls other aspects of the year comparison:

OPTION SCORES

VALUE TRANSYY,[number]

Compares the date after transposing the dates in the YY part of a year in the CCYY format and returns the

TRANSYY

value based on the match. For example, the year 1936 is compared to the year 1963.

If the number is greater than 0, the

TRANSYY

option is enabled and returns the score.

The

TRANSYY

value is returned if the difference is less than or equal to the value specified for the range in local options. If the Extended Range value is specified in local options, the value is adjusted as the extended range.
