LLM-powered rephrasing boosts social media topic modeling accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TM-Rephrase, a novel framework designed to improve the topic modeling of short texts from social media platforms like X (formerly Twitter). This model-agnostic approach utilizes large language models to rephrase informal tweets into more standardized language before topic modeling is applied. A case study using COVID-19 related tweets demonstrated that TM-Rephrase enhances topic coherence, uniqueness, and diversity, with a colloquial-to-formal rephrasing strategy showing the most significant improvements, particularly for the Latent Dirichlet Allocation algorithm.
