Abstract: The emergence of sophisticated e-commerce ecosystems has transitioned the shopping cart from a static container into a dynamic, real-time decision hub. Conventional recommendation engines, rooted in collaborative filtering and simple recurrent architectures, frequently encounter limitations in modeling the high-order, non-linear dependencies prevalent in modern consumer behavior. This white paper provides an exhaustive analysis of Graph Neural Networks (GNNs) as a transformative paradigm for optimizing shopping cart dynamics. By leveraging the topological properties of user-product interaction graphs, GNNs facilitate the propagation of multi-hop relational signals, enabling more accurate next-click predictions, bundle optimizations, and intent detection. We examine core architectures including Graph Convolutional Networks (GCNs), Graph Attention Networks (GATs), and specialized frameworks such as Session-based Recommendation with Graph Neural Networks (SR-GNN) and Content Collaborative Graph Neural Networks (CC-GNN). Our analysis demonstrates that GNNs consistently provide superior representational power compared to traditional models, particularly under conditions of data sparsity and label scarcity. The integration of temporal dynamics and contrastive learning further addresses industrial challenges such as the cold-start problem and real-time latency. This research underscores the pivotal role of graph representation learning in enhancing personalization and user experience in the digital marketplace.
