While LLMs are proficient in processing and generating natural language at scale, the structured, interconnected approach of ontologies and knowledge graphs remains critical for managing complex, entity-rich data. This talk will explore the evolving interplay between LLMs and knowledge graphs, emphasizing how each can complement the other: LLMs can enhance knowledge graph development by assisting in schema design, knowledge extraction, and quality assurance, while knowledge graphs offer LLMs a foundation to improve accuracy and reduce hallucinations. We will examine both the opportunities and challenges of this synergy, outlining practical strategies for getting the best of the two worlds.<\/p>\n\n\n\n<p><strong>Panos Alexopoulos<\/strong> has been working since 2006 at the intersection of data, semantics and software, contributing in building intelligent systems that deliver value to business and society. Born and raised in Athens, Greece, Panos currently works as a principal educator at OWLTECH, developing and delivering training workshops that provide actionable knowledge and insights for data and AI practitioners. He also works as Head of Ontology at Textkernel BV, in Amsterdam, Netherlands, leading a team of data professionals in developing and delivering a large cross-lingual Knowledge Graph in the HR and Recruitment domain.<\/p>\n\n\n\n<p>Panos has published several papers at international conferences, journals and books, and he is a regular speaker in both academic and industry venues. He is also the author of the O\u2019Reilly book \u201cSemantic Modeling for Data \u2013 Avoiding Pitfalls and Dilemmas\u201d, a practical and pragmatic field guide for data practitioners that want to learn how semantic data modeling is applied in the real world.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https:\/\/www.tdwi.fi\/blog\/blog\/wp-content\/uploads\/2024\/11\/Panos-A-pic.jpg\"><img decoding=\"async\" src=\"https:\/\/www.tdwi.fi\/blog\/blog\/wp-content\/uploads\/2024\/11\/Panos-A-pic.jpg\" alt=\"\" class=\"wp-image-2214\" style=\"width:162px;height:auto\"\/><\/a><\/figure>\n<\/div>\n\n\n<p>\u2013 tapahtumamme p\u00e4\u00e4ttyy viimeist\u00e4\u00e4n 16:30.
