The integration of Graph Neural Networks (GNNs) and Large Language Models (LLMs) is driving significant advancements in graph-based learning. A notable trend is the development of methods that leverage LLMs to enhance graph data preprocessing and feature extraction, enabling more effective cross-graph feature alignment and node classification. These innovations are particularly impactful in scenarios where textual data is scarce or non-existent, as they allow for the synthesis of text-attributed graphs from traditional graphs. Additionally, the use of LLMs in a cost-effective, label-free node classification framework is demonstrating superior performance over traditional methods, reducing the dependency on expensive labeled data. The synergy between GNNs and LLMs is also being explored to improve data quality and model generalization across diverse tasks and domains, with applications ranging from gene ontology annotation to career path prediction. Notably, the creation of unified datasets and benchmarks is further solidifying the foundation for these advancements, ensuring reliable and scalable solutions for real-world challenges.
