Flexible English writing support based on negative-positive conversion method

With development of the recent globalization, the chance to exchange in English increased in the business field. In particular, it's necessary to write a thesis and a charter handwriting in English. Because many Japanese are not used to making English sentence, it is a great burden to write appropriate sentence in English without any support for creating English sentence. In this study we have developed an English composition support system. By this system, it's to search for the interlinear translation example to refer to by database and generate a new sentence by replacing a noun in the example sentence. In this paper, based on the technique of Super-Function, we propose a method to convert an affirmative sentence into negative sentence and vice versa to realize more flexible and extensive text conversion.
