Researchers have developed a novel high-level text preprocessing framework designed to improve semantic similarity analysis for discursive texts. This method aims to mitigate semantic diffusion, where similarity scores are inflated by vocabulary acquired through discussion rather than substantive alignment. The framework introduces 12 rules to isolate a document's core claims from its discursive structure before standard NLP preprocessing. An empirical demonstration on philosophical texts from the Stanford Encyclopedia of Philosophy showed that this preprocessing reduces similarity scores and improves cross-model agreement, as measured by a new metric called the semantic diffusion index (SDI).
