用音素编码分析但丁《神曲》的局部结构演化
From graphemic dependence to lexical structure: a Markovian perspective on Dante's Commedia
- 将诗中音节转为辅音/元音序列，建模为四状态马尔可夫链
- 从地狱篇到天堂篇，音素依赖性呈微弱持续上升趋势
- 发现重复出现的音素组合，关联词法与拼写特征
本研究通过元音-辅音（V/C）编码的符号表示，探究但丁《神曲》的结构组织。将所得序列建模为四状态马尔可夫链，得到一个简洁的音素记忆指数，捕捉局部持续性与交替模式。全诗范围内，该指数从《地狱篇》到《天堂篇》呈现轻微但稳定的上升，表明局部依赖结构存在方向性演变。三元组分析识别出一组有限的重复配置，作为音素探针，将马尔可夫模式与词法环境及撇号形式等正字法现象关联。互补分类分析揭示各篇章特有的词汇锚点，显示局部符号依赖既反映三篇章间的分离，也体现全诗的连续进展。结果提供了一个可解释的框架，连接局部符号结构与更高层级文本组织。
原文摘要 · Abstract (English)
This study investigates the structural organisation of Dante's Divina Commedia through a symbolic representation based on vowel-consonant (V/C) encoding. Modelling the resulting sequence as a four-state Markov chain yields a parsimonious index of graphemic memory, capturing local persistence and alternation patterns. Across the poem, this index shows a slight but consistent increase from the Inferno to the Paradiso, indicating a directional shift in local dependency structure. Trigram analysis identifies a restricted set of recurrent configurations acting as graphemic probes, linking Markov patterns to lexical environments and orthographic phenomena such as apostrophised forms. A complementary classification analysis identifies cantica-specific lexical anchors, showing that local symbolic dependencies reflect both the separation among the three cantiche and a continuous progression across the poem. The results provide an interpretable framework connecting local symbolic structure with higher-level textual organisation.
