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.
