TopicMerge 结合了 LLM 和高效聚类技术,实现了可扩展的主题建模

研究人员推出了一种名为 TopicMerge 的新颖两阶段流水线,该方法通过结合高效聚类和大型语言模型(LLM)的强大功能来改进主题建模。该方法首先将文档分割成大量小型聚类,然后对其进行语义标记。随后,LLM 基于局部上下文迭代地合并这些微聚类,从而在显著降低计算成本的同时实现了最先进的性能。实验表明,与传统的文档级方法相比,TopicMerge 可将 LLM 调用次数减少 92% 以上,为主题分析提供了更具可扩展性和效率的解决方案。 AI

影响 提供了一种计算效率更高的方法来使用 LLM 进行主题建模,有可能在大规模文本分析中得到更广泛的应用。

    TopicMerge:一种分而治之的主题建模方法

    arXiv:2610.19323v1 Announce Type: new Abstract: Recent advancements in topic modeling have split into two main paths: efficient embedding-based methods that offer scalability but are often outperformed on standard clustering metrics, and Large Language Model (LLM) approaches that…
