LanguageDetection

Ruby bindings for Chromium Compact Language Detector (source). This gem is using source codes from chromium-compact-language-detector port.

Installation

Add this line to your application's Gemfile:

gem 'language_detection'

And then execute:

$ bundle

Or install it yourself as:

$ gem install language_detection

Usage

>> require 'language_detection'
=> true
>> language = LanguageDetection.perform("This is some example text for language detection")
=> #<LanguageDetection::Language:0x007fae0404f628 @name="english", @code="en", @reliable=true, @text_bytes=51, @details=[#<LanguageDetection::Language:0x007fae0404eb10 @name="english", @code="en", @details=[], @percent=100, @score=49.43273905996759>]>
>> language.name
=> "english"
>> language.code
=> "en"
>> language.reliable
=> true
>> language.details # contains up to 3 languages sorted by score
=> [#<LanguageDetection::Language:0x007fae0404eb10 @name="english", @code="en", @details=[], @percent=100, @score=49.43273905996759>]
>> language.details.first.percent
=> 100
>> language.details.first.score
=> 49.43273905996759

the other way is to include LanguageDetection module in your class

class Article
  include LanguageDetection

  attr_accessor :title, :content

  def initialize(params = {})
    @title   = params[:title]
    @content = params[:content]
  end

  def to_s
    "#{title}\n#{content}"
  end
end

which provides Article#language method using Article#to_s method as parameter

>> article = Article.new :title => "Web development that doesn't hurt", :content => "Tens of thousands of Rails applications are already live..."
>> article.language
=> #<LanguageDetection::Language:0x007fae049dd8e8 @name="english", @code="en", @reliable=true, @text_bytes=93, @details=[#<LanguageDetection::Language:0x007fae049dd118 @name="english", @code="en", @details=[], @percent=100, @score=80.22690437601297>]>

or you can add String#language method by require 'language_detection/string'

>> require 'language_detection'
=> true
>> require 'language_detection/string'
=> true
>> "Web development that doesn't hurt".language
=> #<LanguageDetection::Language:0x007fae049cfec8 @name="english", @code="en", @reliable=true, @text_bytes=36, @details=[#<LanguageDetection::Language:0x007fae049cf7e8 @name="english", @code="en", @details=[], @percent=100, @score=39.70826580226905>]>
