The story formation defined here means a process of connecting the given sentences, which are logically independent of one another, and creating a new story of which the plot is reasonable. Such a work will be very essential near future to automatic writing of scenario of abstract, but it is not easy because creation is an innate ability of a man. The method suggested here is as follows: (1) a man first makes a fuzzy graph where the verteces are the given short sentences, (2) next he finds the fuzzy labels of verteces and the fuzzy relations among the verteces, (3) according to a given strategy, the computer searches its subgraphs of which the plots are semantically reasonable.
These subgraphs corresponds to the backgrounds and episodes of the candidate stories. A new fuzzy graph is mode of these episodes and backgrounds, and the same procedures are repeated until they are converged. As the result some candidate stories are induced. Though the final selection of the candidate stories is done by the computer, the man can easily intervene in it, because a fuzzy integral is adopted here as the criterion function and its fuzzy measures are difined subjectively.
Some numerical examples show us the validity of this method.
