Temporal Knowledge Graph Reasoning: A Review

Over the past few years, temporal knowledge graph reasoning has garnered considerable attention, driven by the time-sensitive nature of real-world knowledge. This paper presents a review of recent advancements in research on temporal knowledge graph reasoning. We start by defining the problem, exploring benchmark datasets, and outlining evaluation metrics specific to this domain. Then, we delve into existing methodologies, categorized by the temporal dimension of the reasoned facts. Finally, we offer insights into potential future research directions in temporal knowledge graph reasoning.
