Abstract

A machine translation system has an input unit for inputting an original sentence, a dictionary section for storing language information used in translation processing, a translation processor for translation-processing the original sentence with reference to the language information stored in the dictionary section, and an output unit for outputting a translated sentence obtained by the translation processor. The translation processor has an analysis section, a translated sentence generation section, and a punctuation mark generation section. The analysis section analyzes the original sentence. The translated sentence generation section generates the translated sentence in accordance with the analysis result of the analysis section. The punctuation mark generation section generates a punctuation mark substantially independently of a punctuation mark present in the original sentence, and appropriately inserts it in the translated sentence.
