How does Google Translation work?

To develop Google Translation, Google first used bilingual dictionaries. However, this approach, which required a lot of time and resources, was abandoned in favour of the statistical machine translation. The Search Engine was based on the work of Franz-Josef Och, who now runs Google Translation. This linguistic researcher is working on the analysis of millions of “parallel” data (from French to English, German to Chinese, etc.). To do this, Google used United Nations documents, which were therefore translated by human translators: the Search Engine therefore first offered translations in the languages used within the United Nations (UN).

When is a Google Breton translation due?

While this approach is efficient and provides a certain accuracy in translation, it does not allow direct access to all languages and dialects, as translations between two little-spoken languages are rare. To switch from Greek to Corsican, for example, you have to use English as an intermediate language.

And for some regional languages such as Breton, it is still not available… Google has not yet amassed enough texts already translated into Breton by reputable organizations to be able to offer it. Its machine learning algorithms require huge amounts of data to learn and reach a sufficient level to be made available.

What are the possible modes?

Google Translation offers 6 ways to communicate in several languages :

  • Text input: just use your keyboard.
  • Conversation: engage in a bilingual conversation.
  • Photos: Translate text visible in images into another language.
  • Visual translation: use your phone’s camera to view instant translations.
  • Handwriting: Draw letters or characters with your finger.
  • Offline: translate text even offline.

How to use Google Translate

While the approach used to develop Google’s translation service is complex, its use is very simple. Simply add a word, a sentence, or even a text containing several hundred words, in the box corresponding to the original language. You then have to choose the language in which the word or text will be translated. It is even possible to listen to the pronunciation of the word to be translated and the translated word in some languages. Google Translation also provides definitions of the word to be translated and synonyms for the proposed translation, also in some languages.

These indications serve to guide the Internet user in his translation by offering him a panel of translations that he can use according to the given context. They address Google Translation’s main shortcoming, which is that they do not take into account the context or the different meanings of a word, thus resulting in inaccurate or even nonsensical translations.

Today, Google’s machine translation service is used by more than two hundred million Internet users and translates in one day the equivalent of the work produced by all the translators in the world in one year (or 1 billion translations, source Amit Singhal).

Why does Google (sometimes) suck so bad?

To translate from one language to another, Google uses multilingual corpora, for example texts translated by the UN into the 6 main languages. When he has enough texts translated from the requested source language into the requested target language, all is well. But when it’s not the case, Google goes through intermediate languages and it gives weird results, even very bad results…

Here are the explanations in video (by a person who works for a human translation service):
