arXiv:2510.16311v3 Announce Type: replace Abstract: Graph Contrastive Learning (GCL) has emerged as a powerful tool for extracting consistent representations from graphs, independent of labeled information. However, existing methods predominantly focus on undirected graphs, disregarding the pivotal directional information that is fundamental and indispensable in real-world networks (e.g., social networks and recommendations).In this paper, we introduce S2-DiGCL, a novel framework that emphasizes spatial insights from complex and real domain perspectives for directed graph (digraph) contrastive
The paper addresses a significant limitation in current Graph Contrastive Learning (GCL) methodologies, which have primarily focused on undirected graphs, despite the prevalence and importance of directional information in real-world networks.
This development can significantly improve the accuracy and applicability of AI models in complex systems like social networks and recommendation engines, thereby enhancing the performance of AI agents and services built upon these structures.
The introduction of S2-DiGCL provides a framework specifically designed for directed graphs, enabling more sophisticated and accurate representation learning in domains where directional relationships are critical.
