Introduction
The introduction discusses the challenges researchers face in finding relevant reference papers due to the rapid growth of scientific publications. It highlights the limitations of existing methods that treat citation relationships as static and emphasizes the need for a dynamic approach that considers the evolving impact of citations over time.
Graph Neural Networks
Graph Neural Networks (GNNs) have transformed link prediction in graphs by learning complex node representations. This section details various GNN architectures and their applications, emphasizing their focus on static graphs and the need for models that can handle dynamic citation networks.
