<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for constructing a target language word inflection model (TLWI model) which can improve translation precision when translating into a target language having word inflections. <P>SOLUTION: A word string obtained by adding a part of speech to the base form of each word in a source language corpus is generated for a corpus pair of a source language corpus and a target language corpus, pre-processing for adding a part of speech to the base form of each word in the target language corpus to generate a word string with the part of speech added thereto is performed, a word C of the source language associated with a word W whose word form in the target language is inflected is obtained on the basis of word association information obtained by making a word in the pre-processed source language corpus associate with a word in a corresponding pre-processed target language corpus, and a pattern containing the word inflection information (TLWI information) of a word W of the target language is generated on the basis of a combination of the word W of the target language, the word C of the source language and words existing around the word C in un-pre-processed source language corpus. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
