DESCRIPTION
This module provides a function to guess the gender of commonly
encountered people's names in Indonesia, using several algorithms.
FUNCTIONS
guess_gender([OPTS, ]FIRSTNAME...) => (RES, ...)
Guess the gender of given first name(s). An optional hashref OPTS can
be given as the first argument. Valid pair for OPTS:
algos => [ALGO, ...]
Set the algorithms to use, in that order. Default is [qw/common
v1_rules/]. Known algorithms: common (try to match from the list of
common names), v1_rules (use some simple heuristics), google (compare
the number of Google search results for "bapak FIRSTNAME" vs "ibu
FIRSTNAME").
The choice of algorithms can severely impact the result. For example,
"Mega" is actually pretty ambivalent, used by both females and males.
But Google search for "ibu mega" will return much more results than
"bapak mega", thus the google algorithm will decide that "Mega" is
predominantly female.
min_guess_confidence => FRACTION
Minimum guess confidence level to accept an algorithm's guess as the
final answer, a number between 0 and 1. Default is 0.51 (51%).
try_all => BOOL
Whether to try all algorithms specified in algorithms. Default is 0,
which means stop trying after an algorithm succeeds to generate guess
with specified minimum guess confidence. If set to 1, all algorithms
will be tried and the best result used.
algo_opts => {ALGO => OPTS, ...}
Specify per-algorithm options. See the algorithm's documentation for
known options.
Will return a result hashref RES for each given input. Known pair of
RES:
result => "M" or "F" or "both" OR "neither" OR undef
The final guess result. undef if no algorithm succeeded. "M" if name
is predominantly male. "F" if name is predominantly female. "both" if
name is ambivalent. "neither" if sufficiently confident that the name
is not a person's name.
guess_confidence => FRACTION
The final guess confidence level.
gender_ratio => FRACTION
Estimation of gender ratio. 1 (100%) means the name is always used
for male or female. 0.9 (90%) means sometimes (about 10% of the time)
the name is also used for the opposite sex. If the gender ratio is
close to 0.5 it means the name is ambivalent and often used equally
by males and females.
algo => FRACTION
The algo that is used to get the final result.
algo_res => [RES, ...]
Per-algorithm result. Usually only useful for debugging.
BUGS/TODOS
This is a preliminary release. List of common names is not very
complete. Heuristic rules are still too simplistic. Expect the accuracy
of this module to improve in subsequent releases.
