A hackneyed analogy between a living thing and a narrative provided us with authentically scientific approach by Propp in the field of narratology. The aim of this article is to make a rough sketch of the present and future situation of numerical analysis in folktale studies which we have started from the medieval French fabliau. By using Tesnière's structural syntax model, we can describe a motif, the minimal unit for the analysis, as a tree diagram that represents the dependency relations between a predicate and the other terms. We decompose further this tree diagram into terms and sub-decompose the latter into semes in order to obtain data that represents simultaneously the syntagmatic and paradigmatic structure of a narrative at a deep semantic level. This data can be handled by various computational tools based on a few models of genome informatics. Methodologically speaking, post-genome informatics which is now trying, from the end of reduction to the constituents, a synthesis of them to elucidate the vital phenomena as a complex system will be the fundamental model for the study of narratology also including the automatic narrative generation system.
