The present invention relates to a method and apparatus for constructing translation knowledge to be used in a translator. According to the invention, a source-language sentence and a target-language sentence are converted by receiving the source-language sentence and the target-language sentence corresponding to the source-language sentence and attaching a prototype, a part-of-speech, relative position information, and syntactic information in a base phrase to each morpheme of the source-language sentence and the target-language sentence. Then, word alignment and syntactic alignment are performed in the converted source-language sentence and target-language sentence, thereby extracting translation knowledge on words and syntaxes, translation knowledge on a subcategory of a bilingual inflected-word, and translation knowledge on a bilingual sentence pattern based on the results of the word and syntactic alignment.

Method and apparatus for constructing translation knowledge

Disclosed is a machine translation method for a PDF file. A machine translation device extracts source language text and non-text from the input source language PDF file through image transformation, corrects the extracted source language text by using the source language text extracted from text information, restores a part that is contextually separated by the non-text from among the extracted source language text, generates a source language XML/HTML file by rearranging the extracted text and non-text so as to satisfy the contextual flow of the source language PDF file, separates source language text from a tag of the source language XML/HTML file, generates target language text by using translation knowledge and a transformation engine specified for the technical field corresponding to the source language PDF file, inserts the translated target language text other than source language text into XML/HTML file, and transforms the generated target language XML/HTML file into a target language PDF file to be output.
