language_detection

Detect the language from a given text. To do that it generates a language profile based on N-grams for every file in etc directory. Then it generate such language profile for the unknown text and compare the previosly language profiles against the unknown.

Requirements:

Only requirement is a PHP version greater than or equal to 7.1. > Note: language_detection requires the Multibyte String extension in order to work.

Install via Composer

composer require patrick-schur/language-detection

Or add the following to composer.json

{
  "require": {
     "patrick-schur/language-detection": "*"
  }
}

Basic Usage

Before we can recognize the language from a given text, we have to generate a language profile for each language. From the beginning it comes with a pre-trained language profile (etc/_langs.json).<br> Also you can add new files to etc or change existing ones.

First we have to generate a language profile.

require_once 'vendor/autoload.php';
 
use LanguageDetector\Trainer;
 
$t = new Trainer;
 
$t->learn();

If we have our language profile, we can classify texts by their language. To detect the language correctly, the length of the input text should be at least some sentences.

require_once 'vendor/autoload.php';
 
use LanguageDetector\LanguageDetector;
 
$ld = new LanguageDetector;
 
var_dump($ld->detect('Das ist ein deutscher Satz.')); // de
