Roger Baklund

This package can be used to determine if words in a string are real or made up.

It provides two classes to analise individual words or sentences to evaluate the presence of vowels and consonants.

The classes provide statistics about the string and a score that can be used to determine if the words really exist or are invented due to the presence of many consecutive consonants.

Innovation Award
PHP Programming Innovation award nominee
January 2014
Number 2

Prize: One copy of the Zend Studio		 Sometimes it is necessary to determine if a word was written by a real person or is not a real a word.

This class provides a solution to evaluate the probability of a word or a phrase being real or made up.

It analyses the presence of vowels and consonants and returns a score that can be low if there are too many consecutive consonants.

<?php

require_once('VowCon.php');

echo "Testing VowConStats class:\n\n";

$words = array("sportsdrink","abc","bcd","aui","aaa","aaaa",
  "asdasdasd","kjhgf","aeiou","klkla",
  "recognition", "floccinauccinihilipilification",
  "paraskevidekatriaphobia","antidisestablishmentarianism");
$v = new VowConStats();
foreach($words as $word) {
  $s = $v->Stats($word);
  echo sprintf("%-30s => %.2f %s\n",$word,round($s->score,2),
    ($s->score > 5.0 ? '!!':
    ($s->score > 3.5 ? '!':'')));
}

echo "\nTesting VowConAnalyzer class:\n\n";

$v = new VowConAnalyzer();

echo "For analyzing a collection of words. There are four properties\n".
     "which can be used to configure the operation. The default values\n".
     "are as follows:\n\n";
echo 'MaxAvgScore: '.$v->MaxAvgScore."\n".
     'MaxWordScore: '.$v->MaxWordScore."\n".
     'MaxBadPercent: '.$v->MaxBadPercent."\n".
     'BadWordLimit: '.$v->BadWordLimit."\n\n".

# load words, parameter can be array of words or a string
# which will be split using the Split() method
$v->LoadText($words);

echo "Status for the test word collection:\n\n";

echo '$v->GetTextStatus() => '.$v->GetTextStatus()."\n";

echo 'count($v->words) => '.count($v->words)."\n";
echo '$v->TextStats->MaxScore => '.$v->TextStats->MaxScore."\n";
echo '$v->TextStats->AvgScore => '.$v->TextStats->AvgScore."\n";
echo '$v->TextStats->BadPercent => '.$v->TextStats->BadPercent."\n";

echo "\nLooping over the collection:\n\n";
foreach($v->words as $word) {
  $s = $v->GetWordScore($word);
  echo sprintf("%-30s => %.2f %s\n",$word,round($s,2),
    $v->WordIsValid($word)? # using BadWordLimit
    'OK':($s > $v->MaxWordScore ? 'Above max word score':'Above bad word limit'));
}

Details

VowCon

This package provides two classes which can be used for analyzing text with regards to patterns of vowels and consonants. In natural language, there is a certain balance between the two: there are rarely very many consecutive consonants or vowels in a real word.

Many spambots include a randomly generated word in their payload, these words will fail the tests provided by this package.
