ULTRA_(machine_translation_system)
ULTRA is a machine translation system created for five languages (Japanese, Chinese, Spanish, English, and German) in the Computing Research Laboratory in 1991.
ULTRA (Universal Language Translator), is a machine translation system developed at the Computing Research Laboratory,[1] which can translate between five languages (Japanese, Chinese, Spanish, English and German). It uses Artificial intelligence as well as linguistic and logic programming methods. The main goal of the system is to be robust, to cover general language and to be simple to use. It uses bidirectional parsers/generators.
The system has a language-independent system of intermediate representation, which means that it takes into account needs for expression (expression is one of the main elements of language) and it uses relaxation techniques to provide the best translation. It used an X Window user interface.[2]
