PROJECT


Build a Language Detector

In this project, we will build a text-based language detector in Python to identify languages using Flask.

Build a Language Detector

You will learn to:

Scrape data using Python.

Preprocess text data.

Create a language detection model without complex computations.

Create a simple Flask application.

Project Description

This project aims to develop a language detection system capable of identifying the language of a given text document. The system utilizes n-grams, sequences of contiguous items (typically characters or words), to extract language-specific patterns from the text. It involves several stages: data collection from public domain books in various languages, text tokenization, n-gram generation, and language identification based on comparing n-grams frequencies with pretrained language models.

Technologies and libraries employed include Python libraries for text processing and web scraping. The end product is a language detection system capable of identifying the language of input text. The application’s modularity allows for easy expansion with additional languages and, hence, a better language identification system.
