English-Japanese Translation Through Case-Structure Conversion

This paper reports some trials on mechanical translation from English to Japanese through a case structure constructed on Hornby~s verb patterns. Though the general theoryof case structures is still at the beginning of study, it provides partial sentential patterns with rough but resonable classification labels. After determination of schematic dependency relations, multi-vocal problems for choosing appropriate equivalents are dissolved using subcategories of terms and cases. Case structures of English are transformed into those of Japanese if necessary, and from those , Japanese sentences are generated by a Japanese grammar.
