Atlas Ii

ATLAS II is a semantic-based machine translation system which aims at high quality multilingual translation. In order to develop a system which deals with various languages with a high degree of precision, analysis and generation mechanisms must be independent of any language, and linguistic knowledge of one language must be independent of other languages. Therefore, we adopt the interlingua approach, which uses conceptual structure as an interlingua, and develop a language-independent processing method, with a language-independent dictionary structure. In this paper, we present the ATLAS II translation mechanism, emphasizing the processing method, and explain what kind of knowledge is used for translation.
