AI Summary

This study addresses the longstanding challenge of quantifying and scaling intertextuality analysis in literary texts. We propose a novel intertextuality modeling method based on *n*-gram embeddings: texts are segmented into *n*-gram sequences, projected into a unified semantic space, and pairwise intertextual strength is computed as the average cosine similarity across all *n*-gram embeddings—yielding an intertextual strength matrix and enabling intertextual network construction for identifying central texts and community structures. This work pioneers the systematic application of *n*-gram embeddings to intertextuality quantification, overcoming limitations of manual annotation and syntactic matching while ensuring scalability and interpretability. Empirical evaluation on four benchmark texts confirms validity; large-scale validation across 267 heterogeneous literary works demonstrates efficiency and robustness. The approach establishes a new paradigm for cross-text relational mining in digital humanities.

Abstract

Intertextuality is a central tenet in literary studies. It refers to the intricate links between literary texts that are created by various types of references. This paper proposes a new quantitative model of intertextuality to enable scalable analysis and network-based insights: perform pairwise comparisons of the embeddings of n-grams from two texts and average their results as the overall intertextuality. Validation on four texts with known degrees of intertextuality, alongside a scalability test on 267 diverse texts, demonstrates the method's effectiveness and efficiency. Network analysis further reveals centrality and community structures, affirming the approach's success in capturing and quantifying intertextual relationships.
