Co-Evolving LLMs and Embedding Models via Density-Guided Preference Optimization for Text Clustering

EMNLP 2025

Large language models (LLMs) have shown strong potential in enhancing text clustering when combined with traditional embedding models. However, existing methods predominantly treat LLMs as static pseudo-oracles, i.e., unidirectionally querying them for similarity assessment or data augmentation, whi

Leveraging BERT and TFIDF Features for Short Text Clustering via Alignment-Promoting Co-Training

EMNLP 2024main

BERT and TFIDF features excel in capturing rich semantics and important words, respectively. Since most existing clustering methods are solely based on the BERT model, they often fall short in utilizing keyword information, which, however, is very useful in clustering short texts. In this paper, we…
