BERTopic outperforms STM in analyzing short survey responses

Researchers compared two topic modeling techniques, Structural Topic Models (STM) and BERTopic, for analyzing short, open-ended survey responses. BERTopic generally produced more coherent and interpretable topics, especially when augmented with additional semantic context. While STM offers stronger inferential capabilities for covariate analysis, BERTopic provides more descriptive comparisons. The study offers practical guidance for social science researchers choosing between these complementary methods. AI
