1. An apparatus for generating a transfer dictionary used in a transfer-based translation machine system, the transfer dictionary storing a pair of the source/target language sentences and corresponding source/target language structure information, comprising: a receiving unit for receiving from a user a pair of source/target language sentences, wherein said source language sentence comprises at least one idiom, at least one argument wherein the collocation and the idiom therein are indicated as such, and said target language sentence comprises a target language translation for the idiom and the source language word(s) for the argument; a parsing unit for parsing the source language sentence to generate a corresponding source language syntactic tree data structure including a part-of-speech and syntactic information of each word in the source language sentence; an extracting unit for extracting, from said source language syntactic tree data structure, nodes corresponding to the idiom, the collocation and the argument, respectively, in said source language sentence; a calculating unit for calculating a least common ancestor node of the extracted nodes; a source language structure generating unit for generating source language structure information based on said source language syntactic tree data structure, wherein said language structure information starts from the information of the least common ancestor node; a target language structure generating unit for generating target language structure information by adding the part-of-speech information to each morpheme in said target language sentence and by replacing each source language word in said target language with the corresponding syntactic information within said source language syntactic tree data structure; and a transfer dictionary for storing, as a new entry, the received source/language sentences and the generated source/target language structure information.
