HYBRID AUTOMATIC TRANSLATION APPARATUS AND METHOD BY COMBINING RULE-BASED METHOD AND TRANSLATION PATTERN METHOD, AND THE MEDIUM RECORDING THE PROGRAM

摘要

A hybrid automatic translation device for generating a high quality translation result of high coverage combining a rule-based method and a translation pattern method, a method thereof, and a computer-readable recording medium recording a program are provided to minimize ambiguity of parsing and a side effect of sentence division, and increase correctness of a phrasal pattern for translation pattern matching by extracting only the phrase unit result from a parsing result. A morpheme parser(101) parses morphemes from an input sentence. A tagger(102) determines each part of speech for a morpheme parsing result. A parser(103) parses a tagging result and outputs a parsing tree. A phrasal pattern generator(104) generates the phrasal pattern by extracting a chunking result of the phrases included in a sub category of verbs in the parsing tree. A phrasal pattern translator(105) performs translation for the phrasal pattern by using a translation pattern. A clause structure parser(106) checks a structure of a clause unit for the sentence in case that the translation pattern matching for the phrasal pattern is failed. A partial pattern translator(105-1) recognizes a partial phrasal pattern for each sub-clause by referring to a clause structure parsing result and performs the translation by using a partial translation pattern.
