  • Patent number: 5732276
    Abstract: A system for helping the production of a desired translation by aiding the operator to make revisions within the text results of each stage of the translation process. The system achieves this goal by receiving text inputted by the operator and conferring IDs to each character of text, and for this text, successively proceeding through morphological analysis, conferring of equivalents to content words, and conversion of sentence structure to that of the target language while referring to a dictionary/grammar section and conferring IDs to corresponding language units. Text corresponding to each stage is stored and moreover, the stage to which translation has advanced is detected, and upon receiving a designation as to which translation stage the operator wishes to have displayed, outputted text of the translation process designated by the operator is copied from the corresponding buffer if the most advanced translation process at that time is beyond the designated translation stage.
