Challenge: Existing cross-lingual topic models depend on sparse bilingual resources and often yield incoherent or weakly aligned topics.
Approach: They propose a framework that integrates LLM-guided topic refinement with self-consistency uncertainty quantification to enable black-box, stable, and scalable enhancement of cross-lingual topic models.
Outcome: Experiments on multilingual corpora show that the proposed framework achieves superior topic coherence and alignment while reducing reliance on bilingual dictionaries and expensive LLM calls.

A Multilingual Topic Model for Learning Weighted Topic Links Across Corpora with Low Comparability (D19-1)

Copied to clipboard

Challenge: Existing models implicitly assume that documents in different languages are highly comparable, a false assumption.
Approach: They propose a multilingual topic model that learns weighted topic links and connects cross-lingual topics only when the dominant words defining them are similar.
Outcome: The proposed model outperforms existing models in low-resource language tasks and outperformed LDA and previous models in classification tasks using documents’ topic posteriors as features.
Neural Topic Modeling with Large Language Models in the Loop (2025.acl-long)

Copied to clipboard

Challenge: Large Language Models (LLMs) have demonstrated promising capabilities in topic discovery, but their direct application to topic modeling suffers from issues such as incomplete topic coverage, misalignment of topics, and inefficiency.
Approach: They propose a novel LLM-in-the-loop framework that integrates Large Language Models with Neural Topic Models (NTMs) global topics and document representations are learned through the NTM, while an LLM refines these topics using an Optimal Transport (OT)-based alignment objective.
Outcome: The proposed framework improves topic interpretability while preserving the efficiency of existing NTMs.
