AI总结:

针对大语言模型与RAG系统未整合实体关系和社区结构、限制事实核查信息检索效果的问题,提出融合知识图谱社区结构的零样本框架CommunityKG-RAG,利用多跳特性提升检索准确率与相关性,实验证明其性能优于传统方法,为事实核查提供鲁棒高效的可扩展方案。

摘要:

尽管大语言模型(LLM)和检索增强生成(RAG)系统已取得进展,但它们的有效性往往因未与实体关系和社区结构整合而受限,削弱了其为事实核查提供上下文丰富且准确的信息检索的能力。我们提出CommunityKG-RAG(社区知识图谱-检索增强生成),这是一种新颖的零样本框架,将知识图谱(KG)内的社区结构与RAG系统相整合,以优化事实核查流程。CommunityKG-RAG无需额外训练即可适配新领域和新查询,利用KG中社区结构的多跳特性,显著提升信息检索的准确性和相关性。我们的实验结果表明,CommunityKG-RAG性能优于传统方法,通过提供一种鲁棒、可扩展且高效的解决方案,成为事实核查领域的一项重要进展。

英文摘要:

Despite advancements in Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) systems, their effectiveness is often hindered by a lack of integration with entity relationships and community structures, limiting their ability to provide contextually rich and accurate information retrieval for fact-checking. We introduce CommunityKG-RAG (Community Knowledge Graph-Retrieval Augmented Generation), a novel zero-shot framework that integrates community structures within Knowledge Graphs (KGs) with RAG systems to enhance the fact-checking process. Capable of adapting to new domains and queries without additional training, CommunityKG-RAG utilizes the multi-hop nature of community structures within KGs to significantly improve the accuracy and relevance of information retrieval. Our experimental results demonstrate that CommunityKG-RAG outperforms traditional methods, representing a significant advancement in fact-checking by offering a robust, scalable, and efficient solution.
