In this article, we are going to see how we can easily integrate a Language Detection engine in your project and how to choose and access the right engine according to your data.


Language detection is the task of automatically detecting the language(s) present in a document based on the content of the document. Using a language detection engine, you can obtain the most likely language for a piece of input text, or a set of possible language candidates with their associated probabilities.


Language detection predates computational methods – the earliest interest in the area was motivated by the needs of translators, and simple manual methods were developed to quickly identify documents in specific languages. The earliest known work to describe a functional Language detection program for text is by Mustonen in 1965, who used multiple discriminant

analysis to teach a computer how to distinguish between English, Swedish and Finnish.

In the early 1970s, Nakamura considered the problem of automatic Language detection. His language identifier was able to distinguish between 25 languages written with the Latin alphabet. As features, the method used the occurrence rates of characters and words in each language.

The highest-cited early work on automatic language detection is Cavnar and Trenkle in1994. Cavnar and Trenkle method builds up per-document and per-language profiles, and classifies a document according to which language profile it is most similar to, using a rank-order similarity metric.
