在這篇論文中，我們指出現存的故事生成方法缺少了「多層敘事」(narrative level)的概念，並希望設計一個較為汎用的理論來描述且能與現存方法整合應用。我們首先介紹「真實感與戲劇張力」的兩難，並說明這兩者是如何得以相容；這個結果讓我們得到一種看待虛構性的方法，此即是我們理論的一項基礎元素—「重述關係」(re-describing relation)。繼續展開重述關係，我們可以看到兩個關於媒體對人產生的印象(depiction)的重要觀念：「世界」及「分析性描述」；我們用這些概念設計了形式化的方法，並試著形式化四個常見的修辭手法，最後再試著為 Alfred Noyes 的短篇故事"Midnight Express"建模。

In this thesis, we pointed out the lack of the concept of narrative level in existing works of story generation and aimed at devising a general theory for it that can be fused with the existing works. Started from a dilemma of "balancing reality and dramatic effects", we showed how the ideas are compatible, and it leads to a conception of fictionality, which is our fundamental element –\textit{the re-describing relation}– of the theory. Manifesting the re-describing relation, it shows two important concepts: \textit{world} and \textit{analytic description}, we then derived the formalization from them, and applied on modelling four common rhetorical devices and a short story "Midnight Express" by Alfred Noyes.
