HiTeC: Hierarchical Contrastive Learning on Text-Attributed Hypergraph with Semantic-Aware Augmentation
arXiv:2508.03104v3 Announce Type: replace Abstract: Contrastive learning (CL) has become a dominant paradigm for self-supervised hypergraph learning, enabling effective training without costly labels. However, node entities in real-world hypergraphs are often associated with rich textual information, which has been largely ignored in prior works. Directly applying existing CL-based methods to such text-attributed hypergraphs (TAHGs) leads to three key limitations: (1) The common use of graph-agnostic text encoders fails to capture the correlations between textual semantics and hypergraph topol
The paper addresses a current limitation in self-supervised learning for complex, text-rich hypergraphs, reflecting the ongoing quest for more efficient and robust AI training methodologies.
This research provides a more sophisticated approach to integrating textual semantics with hypergraph topology, which is crucial for advancing AI's ability to process and understand complex, interconnected data.
Traditional contrastive learning methods on text-attributed hypergraphs are shown to be limited, and new semantic-aware augmentation techniques are introduced to overcome these shortcomings.
