Language Detection

Identifies the language of a sentence from character n-grams

1-2 weeks build

Overview

Detects which language a piece of text is written in, including several Indian languages. Character n-grams capture spelling patterns that stay informative even for short inputs, and multinomial naive Bayes is compared with logistic regression on the public WiLI-2018 dataset. The report looks closely at confusable pairs such as Hindi and Marathi.

What makes it stand up

  • 01Character one-to-three-gram features that work on short text
  • 02Naive Bayes and logistic regression compared
  • 03Covers several Indian languages alongside European ones
  • 04Confusion matrix focused on closely related language pairs
  • 05Web app that returns the top three languages with probabilities
