Chinese generation apparatus for machine translation to convert a dependency structure of a Chinese sentence into a Chinese sentence

A Chinese generation apparatus for machine translation which converts a dependency structure of a Chinese sentence into a Chinese sentence, said apparatus comprising:

• a statistic information memory unit that stores an argument item of the dependency structure of the Chinese sentence, a possible sentence pattern, a possible case marker arrangement of each of a plurality of slots and a corresponding probability value;
• an accessory item information memory unit that stores a case marker, a source language surface case marker, an argument semantic code, a semantic code of a modifier and a corresponding phrase head surface case marker and a phrase tail surface case marker;
• a main item location determining unit that retrieves a sub-structure from the dependency structure of an input Chinese sentence, retrieves the corresponding possible sentence pattern and the corresponding possible case marker arrangement in each slot and the corresponding probability value from the statistic information memory unit using a main argument of the sub-structure as a searching key, calculates an evaluation function by using an undetermined modifier case marker and a corresponding statistic information and generates a Chinese phrase structure in accordance with the evaluation function;
• an accessory item generating unit that retrieves the case marker of a leaf node item, the source language surface case marker, the argument semantic code and the corresponding node item semantic code as a searching key from the Chinese phrase structure, that retrieves the phrase head surface case marker and the phrase tail surface case marker from the accessory item information memory unit in accordance with the searching key, and generates a preposition structure for the Chinese phrase structure;
• and
• a post processing unit that retrieves each clause structure from the Chinese phrase structure for generating a question sentence or a “” (“ba”) sentence or a negative sentence or a passive sentence or an imperative sentence and a corresponding tense marker and a punctuation, and converts the Chinese phrase structure into the Chinese sentence with the use of a lining approach.
