What is “Arabizi”?

The Arabic chat language, known as “Arabizi”, is a casual version of written Arabic that was born when Arabic speakers began using Western keyboards to spell out their native language with the Roman alphabet. With the growth of digital communication, Arabizi has become one of the most proliferate online languages. With as many as 420 million speakers in the world, Arabic coverage, and by extension, Arabizi, is necessary for any global text analytics system.

Arabizi transliteration

Rosette API converts all Arabizi variations to the correct modern Arabic word, minimizing information loss and ensuring consistency across translations. Its a linguistic algorithm looks at the frequency of the structural components of each word together with a statistical model trained on the input of millions of Internet users from all over the Arabic-speaking world. It can also transliterate standard Arabic into Arabizi.

In order to process the huge volumes of Arabizi text being created, it must first be converted to the long-form, Modern Standard Arabic (MSA). After Arabizi text has been transliterated to Arabic, it can be run through other forms of linguistic analysis, such as morphology, entity extraction, and sentiment analysis.

How It Works

Accurately translate

The Rosette Chat Translator (RCT) translates Romanized Arabic “chat” (also known as Arabizi) into standard Arabic script with very high accuracy. This product leverages two fundamental techniques:

  • An algorithmic approach, breaking down words into morphological components and phonemes to produce Arabic candidate transliterations. The transliterations are ranked according to many metrics, such as the popularity of the phoneme mappings or how frequently the Arabic output is used in Arabic text.
  • A statistical approach, using a large database of Roman alphabet spellings generated from the input of millions of Arabic speakers online.

This dual algorithmic and statistical approach is increasingly recognized as the most effective method for text analysis and machine translation. Our technology is the only commercially available product offering these features in the realm of Arabic transliteration. RCT is designed for performance and concurrency from the ground up. It is capable of transliterating thousands of words per second, enabling your applications to instantly convert textual input and quickly process large databases of text. Available both as a Java class library and as a web service, the functionality can be integrated into almost any software environment.

Crowd-sourced translations

Unlike machine translation systems which rely on conventional dictionaries, RCT is powered by a database of 300 million Arabic words collected from thousands of different websites. This approach enables translation which reflects contemporary usage throughout the various regional Arabic-speaking online communities. Our database subscription service enables the translation engine to remain current with the latest trends in terminology and personalities.
