In this article, I build an actantial model, $\mathcal{M}$, of John Cage's 1962 indeterminate work ${\mathit{\text{0}}}^{\mathrm{\prime }}{\mathit{\text{00}}}^{\mathrm{\prime }\mathrm{\prime }}$ (4${}^{\mathrm{\prime }}$33${}^{\mathrm{\prime }\mathrm{\prime }}$ No. 2). To further investigate Greimas' actantial axes of desire, knowledge and power, I generate an ontology, $\mathfrak{O}$, that records the facts of the model through hierarchies of relations and concepts. This allows for a conceptual graph (CG), $\mathcal{C}$, that describes the score's instructions and its actants. Extracting subgraphs of $\mathcal{C}$ then allows for reasoned arguments about the implications of Cage's instructions in the score, and in particular, the composer's reference to “an obligation to others.” Through a conceptual graph rule $\mathcal{R}$, I offer a framework for generating the structure of a score-informed interpretation of ${\mathit{\text{0}}}^{\mathrm{\prime }}{\mathit{\text{00}}}^{\mathrm{\prime }\mathrm{\prime }}$ (4${}^{\mathrm{\prime }}$33${}^{\mathrm{\prime }\mathrm{\prime }}$ No. 2) that is based on a number of key conditionals that map the actants of the piece and their relation to the unfolding of the work's narrative.

在本文中，我建立了一个行动模型， $\mathcal{中号}$，约翰·凯奇（John Cage）1962年的不确定作品 ${\mathit{\text{0}}}^{\mathrm{\prime }}{\mathit{\text{00}}}^{\mathrm{\prime }\mathrm{\prime }}$ （4${}^{\mathrm{\prime }}$33${}^{\mathrm{\prime }\mathrm{\prime }}$ 2号）。为了进一步研究Greimas的欲望，知识和力量的行动轴，我生成了一个本体，$\mathfrak{Ø}$，它通过关系和概念的层次结构记录了模型的事实。这允许使用概念图（CG），$\mathcal{C}$，它描述了乐谱的说明及其参与者。提取的子图$\mathcal{C}$然后就分数中Cage指示的含义，尤其是作曲家对“对他人的义务”的提法提出合理的论据。通过概念图规则$\mathcal{[R}$，我提供了一个框架，可用于生成分数通知解释的结构${\mathit{\text{0}}}^{\mathrm{\prime }}{\mathit{\text{00}}}^{\mathrm{\prime }\mathrm{\prime }}$ （4${}^{\mathrm{\prime }}$33${}^{\mathrm{\prime }\mathrm{\prime }}$ No. 2），它基于许多关键条件，这些条件映射了作品的参与者及其与作品叙事展开的关系。
