well , we need a data that contain all the languages  and every language with there words (like a dictionary),
then we use "the edit distance "  to define the language

We use  those sentences to make our training data .  wich contain the keywords for every language 

Determine the keywords for test or the new sentence 

Then we calculate the similarity using distance or probability 

By comparing the new sentence keywords with the old one

on construit une base de connaissance non rededante de chaque langue apartir des phrases d'apprentissage.

pour une nouvelle phrase on calcule la distance de chaque mot de la nouvelle phrase avec les mots d'apprentisage.

la langue en objet est c'elle qui correspond au max des distances minimales

sallem alaykom,

   first , a language detection algorithm is pretty self-explanatory: we'll take text as input and decide which human language the text is written in. We'll be using Algorithmia's language identification algorithm , to give it a try.

   secondlly ,

Language classifications rely upon using an primer of specialized text called a 'corpus'. There is one corpus for each language the algorithm can identify. Speaking in summary, input text is compared to each corpus and pattern matching is used to identify the strongest correlation to a corpus.

Because there are so many potential words to profile in every language, computer scientists use algorithms called 'profiling algorithms' to create a subset of words for each language, to be used for the corpus. The most common strategy is to choose very common words. In English, we might choose words like "the", "and", "of" and "or".

In this example, we will use Node.js to make our request. Keep in mind you may perform any Algorithmia API request with any tools at your disposal. See "Appendix".A to learn how to configure your machine for development with the Algorithmia API in Node.js.

var algorithmia = require("algorithmia");
var client = algorithmia(process.env.ALGORITHMIA_API_KEY);
var input = "This is a demo sentence for language detection.";

client.algo("/nlp/LanguageIdentification/0.1.0").pipe(input).then(function(output) {
    if (output.error) {
        console.log(output.error);
    } else {
        console.log(output.result);
    }
});

Note that the API key should be modified to match your configuration.

This will return the string en to indicate English. You may read more about the implementation and find a list of supported languages on the algortihm's page.

The process of language identification can be represented as a system .this dataflow was used in for text categorization . However, instead of languages, the authors used categories and models were called profiles. Accordingly, the first stage is the modelling stage, where language models are generated. Such models consist of features, representing specific characteristics of language. These features are words or
N-grams with their occurrences in the training set. The language models are determined for each language included in the training corpus. On the other hand a document model is a similar model that is created from an input document for which the language should be determined.
After all the models have been generated, the document model is compared to all language models in the classification stage and the distance between them is measured with the help of classification techniques. The language model that has the minimum distance to the input document represents the language of the document.
