G2T：基于预训练语言模型和社区检测的主题建模简单通用框架【英文版】

英文标题：G2T: A simple but versatile framework for topic modeling based on pretrained language model and community detection中文摘要：本文提出了一种名为图向话题（G2T）的框架，该框架能够使用预训练语言模型获取文档表示，并通过语义图和社区检测等方法进行主题建模。自动评估结果表明，G2T 在英文和中文文档上均取得了最优表现，并且比基线模型产生了更好的可解释性和覆盖范围。英文摘要：It has been reported that clustering-based topic models, which clusterhigh-quality sentence embeddings with an appropriate word selection method, cangenerate better topics than generative probabilistic topic models. However,these approaches suffer fro
