Patent ID: 8818792

Claim:
A verb phrase translation pattern constructing apparatus using bilingual parallel corpus, the apparatus comprising a computer, the computer configured to include: a predicate and argument recognizing unit configured to recognize predicates and arguments of a source sentence and a target sentence using a syntax analysis result of the source sentence and a word alignment result between the source sentence and the target sentence from a plurality of bilingual parallel corpus; a translation pattern candidate extracting unit configured to extract a translation pattern candidate including an original sentence pattern and a translated part pattern using the recognized predicates and arguments of the source sentence and the target sentence and confirm the corresponding occurrence frequency; a translation pattern candidate verifying unit configured to verify the extracted translation pattern candidate using the occurrence frequency of the original sentence pattern or the translated part pattern for the extracted translation pattern candidate and generate a first verb phrase translation pattern according to the verification result; and a translation pattern generalizing unit configured to generalize the generated first verb phrase translation patterns to generate a second verb phrase translation pattern, wherein the translation pattern generalizing unit is configured to make a group of patterns having the same predicate of the original sentence pattern among the first verb phrase translation patterns, and generate a second verb phrase translation pattern for all patterns that belong to the same group using tuples and the frequencies of the extracted tuples.
