A recent surge in heterogeneous graph neural networks (HGNNs) has led to impressive advancements in representation learning by capturing long-range dependencies and heterogeneity at the node level. However, this paper focuses on the often-overlooked impact of node attributes on HGNNs performance within the benchmark task of node classification. The authors empirically find that typical models exhibit a significant decline in performance when classifying nodes with attribute disparities compared to their neighbors. To address this issue, they propose the Attribute-Guided heterogeneous Information Networks representation learning model with Transformer (AGHINT), which integrates higher-order similar neighbor features and modifies the message-passing mechanism based on attribute disparities. Experimental results on three real-world benchmarks demonstrate that AGHINT outperforms state-of-the-art models.

This paper is about how computers learn from complex networks of information. Right now, these computers are very good at learning from simple networks where all the pieces have similar characteristics. But what happens when the pieces are different? The researchers found that the computers struggle to learn from these more complex networks. To fix this problem, they created a new way for the computers to learn by paying attention to how the different pieces relate to each other. They tested their new method on three real-world networks and it worked much better than the old ways.
