text::affixes
Affixes(3pm) User Contributed Perl Documentation Affixes(3pm)NAME
Text::Affixes - Prefixes and suffixes analisys of text
SYNOPSIS
use Text::Affixes;
my $text = "Hello, world. Hello, big world.";
my $prefixes = get_prefixes($text);
# $prefixes now holds
# {
# 3 => {
# 'Hel' => 2,
# 'wor' => 2,
# }
# }
# or
$prefixes = get_prefixes({min => 1, max => 2},$text);
# $prefixes now holds
# {
# 1 => {
# 'H' => 2,
# 'w' => 2,
# 'b' => 1,
# },
# 2 => {
# 'He' => 2,
# 'wo' => 2,
# 'bi' => 1,
# }
# }
# the use for get_suffixes is similar
DESCRIPTION
Provides methods for prefixe and suffix analisys of text.
METHODS
get_prefixes
Extracts prefixes from text. You can specify the minimum and maximum number of characters of prefixes you want.
Returns a reference to a hash, where the specified limits are mapped in hashes; each of those hashes maps every prefix in the text into the
number of times it was found.
By default, both minimum and maximum limits are 3. If the minimum limit is greater than the lower one, an empty hash is returned.
A prefix is considered to be a sequence of word characters (w) in the beginning of a word (that is, after a word boundary) that does not
reach the end of the word ("regular expressionly", a prefix is the $1 of /(w+)w/).
# extracting prefixes of size 3
$prefixes = get_prefixes( $text );
# extracting prefixes of sizes 2 and 3
$prefixes = get_prefixes( {min => 2}, $text );
# extracting prefixes of sizes 3 and 4
$prefixes = get_prefixes( {max => 4}, $text );
# extracting prefixes of sizes 2, 3 and 4
$prefixes = get_prefixes( {min => 2, max=> 4}, $text);
get_suffixes
The get_suffixes function is similar to the get_prefixes one. You should read the documentation for that one and than come back to this
point.
A suffix is considered to be a sequence of word characters (w) in the end of a word (that is, before a word boundary) that does not start
at the beginning of the word ("regular expressionly" speaking, a prefix is the $1 of /w(w+)/).
# extracting suffixes of size 3
$suffixes = get_suffixes( $text );
# extracting suffixes of sizes 2 and 3
$suffixes = get_suffixes( {min => 2}, $text );
# extracting suffixes of sizes 3 and 4
$suffixes = get_suffixes( {max => 4}, $text );
# extracting suffixes of sizes 2, 3 and 4
$suffixes = get_suffixes( {min => 2, max=> 4}, $text);
OPTIONS
Apart from deciding on a minimum and maximum size for prefixes or suffixes, you can also decide on some configuration options.
exclude_numbers
Set to 0 if you consider numbers as part of words. Default value is 1.
# this
get_suffixes( {min => 1, max => 1, exclude_numbers => 0}, "Hello, but w8" );
# returns this:
{
1 => {
'o' => 1,
't' => 1,
'8' => 1
}
}
lowercase
Set to 1 to extract all prefixes in lowercase mode. Default value is 0.
ATTENTION: This does not mean that prefixes with uppercased characters won't be extracted. It means they will be extracted after being
lowercased.
# this...
get_prefixes( {min => 2, max => 2, lowercase => 1}, "Hello, hello");
# returns this:
{
2 => {
'he' => 2
}
}
TO DO
o Make it more efficient (use C for that)
