| Research Abstract |
Written Japanese sentences have often same ending phonemes like " -da. -da. -da.", and thus seem to be stylistically similar or monotone. This is due to the fundamental construction of a Japanese sentence. A typical final word in a Japanese sentence is a verb, an auxiliary verb, or an adjective. They have only three ending phonemes : "-u. ", "-a." and "-i." We considered an automatic method of the resolution of the stylistic monotony of Japanese sentence endings.
(1) As a result of a statistical investigation of the newspaper texts and a psychological experiment, we got the following measure of stylistic monotony. A Japanese text is ibonotony if it contains more than five contiguous sentences having same ending phonemes.
(2) In order to resolve these monotony we considered transformation of "sahen"-verb into "sahen"-noun, and conversion of word affixes. An experimental system showed a resolution rate of 74%.
(3) For a more flexible measure of monotony we statistically examined the sentence endings of a novel by J.Yoshiyuki as well as an essay by S.Maruya.
(4) Transformation or conversion of a sentence ending affects the meaning of the sentence. We investigated the effects from the standpoint of the change of modality.
