The traditional implicit aspect extraction methods require too much manual feature engineering, which are inefficient when processing large-scale data. To address the problem, BERT-based model with different kinds of classifiers is proposed. In this paper, …

An Agent-based Approach to the Gravity Model of Linguistic Diffusion

2025 · SIAM Undergraduate Research Online

Mathematical models of language change promise to provide insight on how community-wide changes emerge from individual speaker interactions.We develop an agent-based model to test the validity of the gravity theory of linguistic diffusion.Our model uses …
