Knowledge Graphs (KGs) have revolutionized knowledge representation, enabling a graph-structured framework where entities and their interrelations are systematically organized. Since their inception, KGs have significantly enhanced various knowledge-aware applications, including recommendation systems and question-answering systems. Sensigrafo, an enterprise KG developed by Expert.AI, exemplifies this advancement by focusing on Natural Language Understanding through a machine-oriented lexicon representation. Despite the progress, maintaining and enriching KGs remains a challenge, often requiring manual efforts. Recent developments in Large Language Models (LLMs) offer promising solutions for KG enrichment (KGE) by leveraging their ability to understand natural language. In this article, we discuss the state-of-the-art LLM-based techniques for KGE and show the challenges associated with automating and deploying these processes in an industrial setup. We then propose our perspective on overcoming problems associated with data quality and scarcity, economic viability, privacy issues, language evolution, and the need to automate the KGE process while maintaining high accuracy.
知识图谱(KGs)彻底改变了知识表示方式,构建了一个实体及其相互关系被系统组织的图结构框架。自诞生以来,知识图谱显著增强了各种知识感知应用,包括推荐系统和问答系统。由Expert.AI开发的企业知识图谱Sensigrafo,通过面向机器的词汇表示专注于自然语言理解,体现了这一进步。尽管取得了进展,但维护和丰富知识图谱仍然是一项挑战,通常需要人工努力。大语言模型(LLMs)的最新发展通过利用其理解自然语言的能力,为知识图谱丰富(KGE)提供了有前景的解决方案。在本文中,我们讨论了基于大语言模型的最新知识图谱丰富技术,并展示了在工业环境中自动化和部署这些过程所面临的挑战。然后,我们提出了关于克服与数据质量和稀缺性、经济可行性、隐私问题、语言演变以及在保持高精度的同时自动化知识图谱丰富过程的需求相关问题的观点。
