• Title: Historia Magistra Vitae: Dynamic Topic Modeling of Roman Literature using Neural Embeddings
• Authors: Michael Ginn, Mans Hulden,
• Abstract summary: We compare topic models built using traditional statistical models (LDA and NMF) and the BERT-based model. We find that while quantitative metrics prefer statistical models, qualitative evaluation finds better insights from the neural model.

• Abstract: Dynamic topic models have been proposed as a tool for historical analysis, but traditional approaches have had limited usefulness, being difficult to configure, interpret, and evaluate. In this work, we experiment with a recent approach for dynamic topic modeling using BERT embeddings. We compare topic models built using traditional statistical models (LDA and NMF) and the BERT-based model, modeling topics over the entire surviving corpus of Roman literature. We find that while quantitative metrics prefer statistical models, qualitative evaluation finds better insights from the neural model. Furthermore, the neural topic model is less sensitive to hyperparameter configuration and thus may make dynamic topic modeling more viable for historical researchers.

  We propose a novel approach that leverages large language models (LLMs) to extend short texts into more detailed sequences before applying topic modeling. Our method significantly improves short-text topic modeling performance, as demonstrated by extensive experiments on real-world datasets with extreme data sparsity.
