Introduction to Language Detection with ‘language-detect’

The ‘language-detect’ library is a powerful tool for identifying the language of a given text. It comes with a wide range of APIs that developers can utilize to build robust language detection features in their applications. In this guide, we will explore various APIs provided by ‘language-detect’ and how to use them with practical code snippets.

Getting Started

To start using the ‘language-detect’ library, you first need to install it. You can do this via pip:

 pip install language-detect 

API Examples

Below are some common API methods provided by the ‘language-detect’ library along with usage examples:

1. Detecting Language of a Text

To detect the language of a given text, use the detect method:

 from language_detect import detect
text = "Bonjour tout le monde" detected_language = detect(text) print(detected_language)  # Output: 'fr' 

2. Detecting Languages with Confidence Scores

The detect_langs method returns the possible languages along with confidence scores:

 from language_detect import detect_langs
text = "Buenos días a todos" detected_languages = detect_langs(text) print(detected_languages) # Output: ['es:0.99', 'pt:0.01'] 

3. Listing Supported Languages

You can list all supported languages using the languages method:

 from language_detect import languages
supported_languages = languages() print(supported_languages) # Output: ['af', 'ar', 'bg', 'bn', 'ca', 'cs', ...] 

4. Detecting Multiple Texts

If you have multiple texts, you can detect the languages for all of them using the batch_detect method:

 from language_detect import batch_detect
texts = ["Hello world!", "Bonjour tout le monde", "Hola a todos"] detected_languages = batch_detect(texts) print(detected_languages) # Output: ['en', 'fr', 'es'] 

Building an Application

Let’s create a simple web application using Flask that utilizes the ‘language-detect’ library.

App Example

 from flask import Flask, request, jsonify from language_detect import detect
app = Flask(__name__)
@app.route('/detect_language', methods=['POST']) def detect_language():
    data = request.get_json()
    text = data.get('text', '')
    language = detect(text)
    return jsonify({'language': language})

if __name__ == '__main__':
    app.run(debug=True)

With this simple Flask application, you can detect the language of a text by sending a POST request to the /detect_language endpoint with a JSON payload containing the text.

Conclusion

We have explored some of the essential APIs provided by the ‘language-detect’ library and demonstrated how to build a simple language detection web application. This will help you get started with incorporating language detection features into your applications effortlessly.
