METHOD AND APPARATUS FOR SELECTING TARGET WORD IN MACHINE TRANSLATION

摘要

A method and an apparatus for selecting a translated word in a machine translation are provided to obtain more natural translation quality by applying a translated word selecting scheme to the machine translation, and to get wanted information from a document written in foreign languages more easily and cheaply. A method for selecting a translated word in a machine translation comprises the following several steps. A co-occurring word class information applying unit checks whether a target word with respect to a word of a source sentence can be determined as a translated word by using a co-occurring word class information database(S300). In case that the target word is not determined from the co-occurring word class information database(S301), a meaning determining unit solves meaning ambiguity of the target word(S302). If the meaning determining unit solves the meaning ambiguity or the number of translated words of a target noun word is more than 2 but the translated words share the same meaning code, the translated word determining unit determines an optimal translated word by using a target language local context statistics information database which is constructed from a target language corpus in order to select more precise translated word(S303,S304).
