Abstract
Abstract A machine translation system has a dictionary wherein a single special cooccurrence code or a collective special cooccurrence code is stored in association with entry words in a first language which have a dependency relation among them and which are separately stored. A pair of entry and equivalent words is associated with another pair of entry and equivalent words via the same single or collective special cooccurrence code when the entry words in the pairs have a dependency relation between them. An equivalent-word selector searches the dictionary for a subordinate-side pair of entry and equivalent words having the same single special cooccurrence code or collective special cooccurrence code as that of a dominant-side pair of entry and equivalent words for a head or modifier in a case structure tree, so that cooccurring equivalent words in a second language of the cooccurring entry words are determined. A translation generator generates a translation in the second language based on the case structure tree and the cooccurring equivalent words determined.
