Abstract
A translation rule learning scheme for a machine translation using a computer, in which an original sentence in a first language and a translated sentence in a second language of a bilingual text are analyzed to obtain dependency structures indicating a predicate and a case information associated with the predicate in each language; case frame correspondences between the first and second languages are estimated by estimating correspondences of words in the dependency structures in the first and second languages according to a bilingual dictionary; the estimated case frame correspondences are modified by comparing the case information in the dependency structures in the first and second languages and estimating a missing case information in one language from an existing case information in another language; and translation rules are extracted from the modified case frame correspondences.
