用大模型分析古代小说中的文学母题，发现共性与演变规律。
Investigating Literary Motifs in Ancient and Medieval Novels with Large Language Models
- 基于微调大模型识别文本中的文学母题
- 部分母题贯穿全期，部分随时间波动
- 为定量定性研究提供数据支持，适合文学分析者
从公元1世纪到15世纪的希腊虚构叙事（常被称为爱情小说或传奇）长期被认为在诸多方面相似，尤其体现在特定文学母题的使用上。本研究采用微调的大语言模型，探究该文集中文本共有的母题及其相互差异。结果显示，某些母题在整个文集中持续存在，而另一些则频率波动，暗示了趋势或外部影响。结论表明，该方法能有效依据既定标准提取文学母题，为定量与定性分析提供数据支持。
原文摘要 · Abstract (English)
The Greek fictional narratives often termed love novels or romances, ranging from the first century CE to the middle of the 15th century, have long been considered as similar in many ways, not least in the use of particular literary motifs. By applying the use of fine-tuned large language models, this study aims to investigate which motifs exactly that the texts in this corpus have in common, and in which ways they differ from each other. The results show that while some motifs persist throughout the corpus, others fluctuate in frequency, indicating certain trends or external influences. Conclusively, the method proves to adequately extract literary motifs according to a set definition, providing data for both quantitative and qualitative analyses.
