Dynamic Graph Neural Networks (GNNs) combine temporal information with GNNs
to capture structural, temporal, and contextual relationships in dynamic graphs
simultaneously, leading to enhanced performance in various applications. As the
demand for dynamic GNNs continues to grow, numerous models and frameworks have
emerged to cater to different application needs. There is a pressing need for a
comprehensive survey that evaluates the performance, strengths, and limitations
of various approaches in this domain. This paper aims to fill this gap by
offering a thorough comparative analysis and experimental evaluation of dynamic
GNNs. It covers 81 dynamic GNN models with a novel taxonomy, 12 dynamic GNN
training frameworks, and commonly used benchmarks. We also conduct experimental
results from testing representative nine dynamic GNN models and three
frameworks on six standard graph datasets. Evaluation metrics focus on
convergence accuracy, training efficiency, and GPU memory usage, enabling a
thorough comparison of performance across various models and frameworks. From
the analysis and evaluation results, we identify key challenges and offer
principles for future research to enhance the design of models and frameworks
in the dynamic GNNs field.
