According to an article published by Alan K. Melby in Revista tradumàtica, such systems consist of three phases of processing:

• Analysis of the source text
• Transfer (to accomodate differences between the source and target languages)
• Generation of the target text from an intermediate representation

Firsty, I will provide five examples by MT systems applied to closely related languages (Spanish, Catalan, Portuguese, French, or Italian) and less related languages (English, Spanish, Japanese, German, Chinese, or Arabic):

MT systems that tranlate closely related languages:

• Instituto Cervantes: Its aim is to translate close languages such as Spanish, Portuguese or Catalan.
• ATS: This company’s goal is to translate close languages such as English, Portuguese or Spanish.

The following MT systems translate less related languages:

• Reverso: This webpage deals with the translation of languages such as Spanish, English, Russian…
• Systran: It translates less related languages such as Chinese, Arabic, English or Portuguese.
• Freetranslation: It translated languages such as Chinese, Arabic, Italian, Portuguese, English.
