In this paper, we consider Vladimir Propp's narrative study from the viewpoint of “de-composition and re-composition”. Propp (В.Я.Пропп) is a 20 century's Russian folklorist and is known as one of pinoneer of narratology. First we show a list of Propp's decomposed narrative elements and some examples of the re-composition as computer programs. Next, based on the attempt of Propp's de-composition and re-composition, we discuss the positioning of Propp model as the narrative rhetoric in narratology and the method and directions for introducing its model into our narrative generation system.
