<p>PURPOSE:To convert an original sentence in a first language to a translated sentence in a second language with a high precision by flexibly selecting word meanings and translated words in the unit of word and phrase so that the original sentence and the translated sentence correspond to each other most suitably. CONSTITUTION:An input sentence in the first language is analyzed to a graph structure having nodal points and branches by an input analysis part 14. In a translated word selector 20, a variable introducing part 22 introduces variables in parts having ambiguity in the graph structure. Restrictions of these variables are propagated to the other parts by a restriction carcelling part 24 to obtain solutions of translated word determination in the other parts, and a contradictionless solution is locally obtained at every part. A variable materializing part 26 locally obtains a solution at every contradictionless part in accordance with the pattern of variables. An output sentence generating part 36 generates a sentence in the second language from a set of these solutions. Consequently, the combination explosion of original words and translate word which can occur at the time of analysis is avoided, and determination of words in the second language in ambiguous parts is delayed till the time just before sentence generation to utilize maximum information.</p> |
