为了总结一个故事，有必要对故事进行高水平的分析，突出其核心概念。一种基于绘图单元的记忆表示技术似乎为这种分析提供了丰富的基础。情节单位是一种概念结构，当叙事连贯时，这些结构相互重叠。当情节单元之间的重叠交叉点被解释为情节单元图形中的圆弧时，生成的图形将对故事的情节进行编码。然后，图表的结构特征揭示了哪些概念是故事的核心，哪些概念是外围概念。目前，计算机模拟实验和心理学实验都将情节单位分析作为叙事总结的一种加工策略进行研究。
In order to summarize a story, it is necessary to access a high level analysis of the story that highlights its central concepts. A technique of memory representation based on plot units appears to provide a rich foundation for such an analysis. Plot units are conceptual structures that overlap with each other when a narrative is cohesive. When overlapping intersections between plot units are interpreted as arcs in a graph of plot units, the resulting graph encodes the plot of the story. Structural features of the graph then reveal which concepts are central to the story, and which concepts are peripheral. Plot unit analysis is currently being investigated as a processing strategy for narrative summarization by both computer simulation and psychological experiments.
