Apparatus and method for constructing verbal phrase translation pattern using bilingual parallel corpus

A verb phrase translation pattern constructing method using bilingual parallel corpus, the method performed by a computer and comprising:

• recognizing 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;
• extracting a translation pattern candidate including an original sentence pattern and a translation pattern using the recognized predicates and arguments of the source sentence and the target sentence, and confirming the corresponding occurrence frequency;
• verifying the extracted translation pattern candidate using the occurrence frequency of the original sentence pattern or the translation pattern for the extracted translation pattern candidate, and generating a first verb phrase translation pattern according to the verification result;
• and
• generalizing the generated first verb phrase translation pattern to generate a second verb phrase translation pattern,
• wherein the generalizing of the generated first verb phrase translation pattern comprises:
• making a group of patterns having the same predicate of the original sentence pattern among the first verb phrase translation patterns, and
• generating the second verb phrase translation pattern for all patterns that belong to the same group using tuples and the frequencies of the extracted tuples.

A non-transitory computer readable recording medium in which a program for causing a computer to execute a verb phrase translation pattern constructing method using bilingual parallel corpus is recorded, the method comprising:

• recognizing 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;
• extracting a translation pattern candidate including an original sentence pattern and a translation pattern using the recognized predicates and arguments of the source sentence and the target sentence, and confirming the corresponding occurrence frequency;
• verifying the extracted translation pattern candidate using the occurrence frequency of the original sentence pattern or the translation pattern for the extracted translation pattern candidate, and generating a first verb phrase translation pattern according to the verification result;
• and
• generalizing the generated first verb phrase translation pattern to generate a second verb phrase translation pattern,
• wherein the generalizing of the generated first verb phrase translation pattern comprises:
• making a group of patterns having the same predicate of the original sentence pattern among the first verb phrase translation patterns, and
• generating the second verb phrase translation pattern for all patterns that belong to the same group using tuples and the frequencies of the extracted tuples.
