Abstract

See full text

A machine translation system capable of performing translation at a high processing speed with improved disambiguation rate in the parsing by applying grammar rules in dependence on the domains to which texts to be translated belong, objects of the texts and rules of sentences in the same text. The machine-translation system for translating a first language to a second language uses a grammer memory for storing grammar rules of the first or second language and a main memory for storing a variety of information, wherein the grammar rules stored in the grammar memory are prepared in groups at least on the basis of the domains to which texts to be translated belong and individual parts in the text. The system includes apparatus for deciding which of the grammar rules stored in the grammar memory should be applied to a given input text, and apparatus for translating the individual parts of the input text by applying the grammar rules determined on the basis of the result of decision made by the deciding apparatus.
