1. A verb pattern automatic extension and verification apparatus for use in a Korean-Chinese machine translation system, comprising: a verb pattern dictionary database in which Korean and Chinese verb patterns are registered; a sentence structure parser for parsing respective sentence structures contained in a newly inputted Korean raw corpus and detecting a verb pattern that is unregistered in the current verb pattern dictionary database among the verb patterns contained in the respective sentences; and a verb pattern generator for automatically generating a source sentence part of the unregistered verb pattern detected by the sentence structure parser, searching a Chinese verb target language corresponding to the verb pattern of the source sentence part in the verb pattern dictionary database to automatically generate a Chinese target sentence part, automatically generating a new verb pattern to newly register the new verb pattern in the verb pattern dictionary database, performing a pattern extension process of checking an identification of voice, a lexical pattern and a Chinese target language with respect to the new verb pattern and the Korean verb pattern having a target language identical to the Chinese verb target language, adding a specific verb pattern candidate, performing an automatic error verification process of judging whether or not the extended verb pattern candidate is registered in a large-capacity corpus database, newly registering the extended verb pattern judged as a suitable pattern in the Korean and Chinese verb pattern dictionary database, and registering the extended verb pattern judged as the error pattern in an error pattern database.
