Knowledge Graphs (KGs) describe relationships between entities as a set of facts. KG embeddings map entities and relations into a vector space while preserving their relational semantics. This enables effective inference of missing knowledge from the embedding space. Most KG embedding approaches focused on triple-shaped KGs. A great amount of real-world knowledge, however, cannot simply be represented by triples.
In recent years, there have been significant advancements in KG embeddings that go beyond the traditional representation of triple-shaped facts. These advancements enable more nuanced and expressive representations, leading to enhanced KG embeddings.
In this tutorial, we will give a systematic introduction to KG embeddings that go beyond the triple representation. In particular, the tutorial will focus on temporal facts where the triples are enriched with temporal information, hyper-relational facts where the triples are enriched with qualifiers, N-ary facts describing relationships between multiple entities, and also facts that are augmented with literal, text, and multimodality. We will also cover advanced topics in beyond-triple KGs such as complex query answering, ontologies, LLMs and so on. During the tutorial, we will introduce both fundamental knowledge and advanced topics for understanding recent embedding approaches for beyond-triple representations.
Our tutorial will be held on October 21 (all the times are based on GMT+1 = UK local time). Slides may be subject to updates.
