AUTOMATIC TRANSLATION DEVICE AND TRANSLATION MODEL LEARNING DEVICE

摘要

PROBLEM TO BE SOLVED: To increase accuracy of automatic translation of long sentences that can be divided into structural components.SOLUTION: A claim translation part 328 includes: a pattern search part 500 which identifies patterns of English claims 334 after syntactic analysis and divides them into structural components; a Japanese pattern generation part 504 which identifies Japanese patterns associated with English patterns; an input sentence division part 502 and a structural component kind determination part 510 which identify correspondence and grammatical characteristics of the structural components between English and Japanese patterns; a statistical automatic translation machine 524 which uses either a noun phrase translation model 320 or a verb phrase translation model 322 which are learned to use word strings of the structural components of the English claims 334 for translation of word strings of the grammatical characteristics of the structural components and generates Japanese translation; and a Japanese pattern substitution part 526 which substitutes respective Japanese translations of the structural components of the English claims 334 for structural components of the Japanese pattern according to the correspondence of the structural components and generates Japanese claims 326.SELECTED DRAWING: Figure 9
