A survey of graph continual learning: a unified taxonomy and research landscape

Real-world networks, such as social, citation, and Internet of Things (IoT) graphs, evolve continuously, with both their topologies and node attributes changing over time. Conventional graph representation learning typically assumes a static structure and requires full retraining when new data arrive, which often results in catastrophic forgetting (CF) across tasks. Graph continual learning (GCL) aims to incrementally integrate new information from temporal graphs while retaining previously acquired knowledge, thereby enabling long-term and adaptive graph intelligence. Despite significant progress, existing studies on GCL remain fragmented and lack a unified conceptual framework. The growing role of external and pretrained knowledge has introduced a new dimension to graph continual learning, posing new challenges to methods that rely solely on traditional techniques. In this survey, we propose a fourfold taxonomy of GCL methods, encompassing replay-based, regularization-based, architecture-based, and knowledge-based approaches. This taxonomy extends core principles of continual learning and emphasizes the transformative impact of external knowledge on graph learning paradigms. Furthermore, we consolidate the GCL research landscape by summarizing representative applications, task formulations, evaluation protocols, and benchmark datasets, providing a foundation for reproducibility and fair comparison. Finally, we discuss emerging directions in cross-modal graph continual learning, the integration of pretrained knowledge into GCL frameworks, and the evolution of evaluation protocols for real-world scenes.
