Knowledge graphs (KGs) have become foundational in representing complex, structured relationships among entities in diverse domains, from social networks to biomedical research. Traditional knowledge graph embedding methods rely on algebraic or geometric models. Still, recent breakthroughs leverage neural architectures, particularly transformers, attention mechanisms, and large language models (LLMs), to learn richer, context-aware embeddings. This workshop will introduce participants to the core concepts and recent advances in applying transformers and LLMs to knowledge graph embedding. We will explore how these techniques utilize both graph structure and textual semantics and examine real-world applications.
