Large Language Models for Knowledge Graph Embedding: A Survey

  • 利用大模型的语义理解能力改进知识图谱嵌入表示
  • 覆盖多模态、开放域等多样化知识图谱场景
  • 适合对知识推理和自然语言交互有需求的研究者

大语言模型(LLMs)在万维网上的诸多知识驱动应用中表现出卓越性能,其通过在海量文本数据上训练数亿甚至更多参数,具备强大的自然语言理解和生成能力。随着其优势日益显现,LLMs被逐步引入知识图谱嵌入(KGE)任务以提升处理效果。传统KGE方法将实体和关系映射到低维向量空间,使知识图谱三元组在向量空间中满足特定打分函数。而基于LLMs强大的语言理解与语义建模能力,它们已在多模态KGE、开放域KGE等不同场景中被不同程度地应用。本文系统调研了各类基于LLMs的KGE相关方法,按任务类型进行分类总结,并讨论其主要应用场景,最后提出该新兴研究方向的未来展望。

原文摘要 · Abstract (English)

Large language models (LLMs) have garnered significant attention for their superior performance in many knowledge-driven applications on the world wide web.These models are designed to train hundreds of millions or more parameters on large amounts of text data, enabling them to understand and generate naturallanguage effectively. As the superior performance of LLMs becomes apparent,they are increasingly being applied to knowledge graph embedding (KGE) related tasks to improve the processing results. Traditional KGE representation learning methods map entities and relations into a low-dimensional vector space, enablingthe triples in the knowledge graph to satisfy a specific scoring function in thevector space. However, based on the powerful language understanding and seman-tic modeling capabilities of LLMs, that have recently been invoked to varying degrees in different types of KGE related scenarios such as multi-modal KGE andopen KGE according to their task characteristics. In this paper, we investigate awide range of approaches for performing LLMs-related tasks in different types of KGE scenarios. To better compare the various approaches, we summarize each KGE scenario in a classification. Finally, we discuss the applications in which the methods are mainly used and suggest several forward-looking directions for the development of this new research area.
