Why NTextCat?

• NTextCat helps to recognize (identify) the language of a given text (e.g. read a sentence and say it is Italian).
• NTextCat can also be used for text classification (e.g. read a paragraph and say it belongs to Sports category).

Try it out yourself: ONLINE DEMO. Recommended input: a snippet of text with at least 5 words (though it works quite OK with just a couple of words).

How to use

NTextCat supports .NET Standard 2.0. Just install the NTextCat NuGet package:

dotnet add package NTextCat

Then we can use NTextCat to detect the language of a text.

using NTextCat;
...
// Don't forget to deploy a language profile (e.g. Core14.profile.xml) with your application.
// (take a look at "content" folder inside of NTextCat nupkg and here: https://github.com/ivanakcheurov/ntextcat/tree/master/src/LanguageModels).
var factory = new RankedLanguageIdentifierFactory();
var identifier = factory.Load("Core14.profile.xml"); // can be an absolute or relative path. Beware of 260 chars limitation of the path length in Windows. Linux allows 4096 chars.
var languages = identifier.Identify("your text to get its language identified");
var mostCertainLanguage = languages.FirstOrDefault();
if (mostCertainLanguage != null)  
    Console.WriteLine("The language of the text is '{0}' (ISO639-3 code)", mostCertainLanguage.Item1.Iso639_3);  
else 
    Console.WriteLine("The language couldn’t be identified with an acceptable degree of certainty");

// outputs: The language of the text is 'eng' (ISO639-3 code)
